Intel released their first generation High-End Desktop (HEDT) platform, the Nehalem (X58 Tylersburg) back in November 2008. At that time, Chipzilla introduced their first high-end desktop processor codenamed Core i7-980X that introduced 6 cores and 12 threads for the first time in the consumer market. The Core i7-980X was followed by the Core i7-990X which featured the same specification and brought a minor clock bump which has become a tradition now a days when companies usually refresh their processor lineups. These chips were the high-end parts of their time and time passed with Intel updating to two new product series and a totally new platform codenamed X79 (Patsburg). The X79 chipset featured the LGA 2011 socket which featured support for the 2012's Sandy Bridge-E and 2013's Ivy Bridge-E processors (32nm and 22nm). While new at the time of its launch, most of the X79 features haven't been upgraded since 2012 on the HEDT side and mainstream platform such as the Z87 and Z97 have picked up the pace in terms of features, designs and overclocking.

Today, Intel has a new platform and not just any platform, a new HEDT platform. Intel has had a heart for PC enthusiasts since their emergence and they have already said that they are committed to the market. To show that, Intel has unveiled their latest X99 platform codenamed Wellsburg and along with it, launched the latest Haswell-E processors. Things are not only great on the performance side but there are some major key updates on the features side as well. The Haswell-E X99 platform actually is the first consumer platform which will set standards for the upcoming platforms since it is the first to support DDR4 memory and a load of new, improved technology enhancements.

The Haswell-E processor family comes a whole slew of a new generation of motherboards, packed full of new features to propel the technological race forward into a state of electric proportions. The LGA2011 V3 socket has brought about a lot of positive commotion in the industry with the X99 chipset while the DDR4 memory is the latest standard in the memory architecture which will boost performance plus bandwidths at very low voltages compared to its predecessors. The X99 motherboards from various manufacturers have been given the same enhancements as the latest Z97 series boards which were introduced with the Haswell Refresh CPU lineup and updated with enhanced designs suited and built for the enthusiast crowd.

Right now, we are looking at three key products, the fastest Haswell-E processor known as the Core i7-5960X, Gigabyte's high-performance and feature loaded X99-UD7 WiFi motherboard and a 16 GB Ripjaws IV memory kit based on the DDR4 standard from our friends at G.Skill. All three products are available to consumers and can be readily purchased from various hardware retail outlets. Our review will show the generational increase in performance and new features and enhancements introduced in Haswell-E and the technologies that have surrounded it at launch. So let's get in and have a look at the Godzilla-E chip!

Haswell-E Architecture Insight

Intel's Haswell-E is codenamed after Haswell  which means its based on the same architecture that makes use of a 22nm Tri-gate 3D transistor technology which is an improvement over the regular Tri-gate transistor technology featured on Ivy Bridge. The Haswell architecture  makes use of a two chip platform technology which includes the processor itself and the Wellburg 9-Series X99 PCH (Platform control hub). Intel's X99 chipset is featured on the LGA 2011-V3 socketed motherboards with which Haswell-E processors are fully compatible.

The Haswell die is largely similar to its predecessors Ivy Bridge and Sandy Bridge. The Haswell-E die comes with up to eightcores which share the same L3 cache. It features 2.6 Billion transistors and a die size of 335.2 mm2 compared to 1.86 Billion (257mm2) on the Ivy bridge-E based Core i7-4960X processor. Other than these, the Haswell die include system agent, display agent, DDR4 Quad Channel Memory controller I/O and PCI-e 3.0 memory controller while the large L3 cache is shared by a slice of four cores on its side. The Haswell instruction set includes Intel VT, AMT 9.0, Intel TXT, SSE4.2, Hyper Threading, Turbo Boost 2.0, AVX2, AES-NI, PCLMULQDQ, Secure key, Intel TSX, PAIR (Power aware interrupt routing and SMEP. Haswell for the first time features C-states of C0, C1, C1E, C3, C6, C7 and enhanced Intel Speedsted technology.

Haswell-E Overclocking and Power Management

Intel shares the same overclocking features introduced on their Devil’s Canyon processor for the Haswell-E CPUs which provides tons of overclocking options to enthusiasts and overclockers.

Intel’s Haswell-E comes with a dynamically adjustable and fully unlocked Turbo Boost Technology limit that ensures users get the most out of their processors when they need it. Core ratios have been unlocked  up to 80 in 100 MHz increments while the CPU voltage is completely controllable via the iVR (Integrated Voltage regulator). DMICLK or BCLK allows for an unlocked PCH clock controller with increments upto 200 MHz while PEG and DMI will offer variable/adjustable ratios based on the BCLK frequency. Similarly, the GPU core also features an unlocked design that allows for frequency adjustments (60 Ratio in 50 MHz increments) and fully programmable voltage via iVR. An unlocked memory controller allows for upto 2933 MHz overclock on the DDR3 modules.

Intel has provided key details on the upcoming iVR through which voltage on CPU and GPU could be dynamically adjusted. Currently, voltage management is accomplished with the use of external VRM’s on the motherboard. There are in total four voltage override modes through the iVR module on Haswell chips which are accounted for when running the processor in default and overclocking mode. With the next generation Haswell processors, we would be looking at an increased BCLK of greater than 167 MHz (non-continuous) compared to the peak 116.95 MHz on Ivy Bridge along with a select CPU PEG/DMI ratios of 5:5, 5:4, 5:3 which is quiet impressive. The next few slides details various performance tuning ratios available on Haswell core for CPU/GPU/DDR/PEG,DMI and Ring.


Intel’s new processor will get a numerical naming scheme; 59xx and 58xx. The 59xx and 58xx series processors are quad-core offerings and will be available from launch. HD4600 however will not be uniformly implemented across the processors. The alphabet suffix will continue to be the same (i.e.“K” for fully unlocked processors, ‘T’ & ‘S’ for low TDP variants) while the new R-Series would be supplied in BGA packages making use of the HD 5200 “Iris Pro” graphics chip.

Intel LGA 2011 V3 Socket

Intel LGA 2011-3 Socket was meant to replace the Ivy Bridge-E HEDT (High End Desktop) platform and is based on the latest second generation 22nm Hi-K process architecture. The most interesting part is that Intel is finally providing up to 8 core SKUs in their desktop lineup with the launch of Haswell-E. Intel has detailed 6-8 cores for their Haswell-E processors that are equipped with massive 20 MB of L3 smart cache and just like Haswell, feature an integrated voltage regulator “FVIR.” Intel is aiming for an 55% IPC improvement over quad cores with their flagship Haswell-E processors.

Just like Haswell and Ivy Bridge-E before it, Haswell-E retains the great overclocking features that would ship with the “K” series and “Extreme Edition” processors. Both the memory and processor can be overclocked beyond limits with unlocked turbo limits, unlocked core ratios in 80/100 increments, programmable iVR voltage, support for XMP mode, unlocked memory controller and voltage limits, native support for memory upto 2667 MHz, Unlocked PCH and PLL voltage controls and more.Gigabyte X99 UD7 WiFi_Socket Close Up 2

Cooler Compatibility With LGA 2011 V3 Socket

Anyone who has a cooler capable of supporting the LGA 2011 socket need not worry about the dash 3 at the end. Any LGA 2011 compatible cooler/bracket combo works on LGA 2011-3 sockets. Intel is advertising to use liquid cooling solutions with the Haswell-E processors since they provide more cooling performance. Intel has their own TS13X liquid cooler which include

First Desktop Platform To Feature DDR4 Memory Support

Coming to the memory controller,  Intel’s Haswell-E is officially the first HEDT platform to feature support for DDR4 memory. The DDR4 memory controller lies on the processor itself through which it is directly connected. The new DDR4 memory modules consume only 1.2 V of power compared to 1.65/1.5V standard with DDR3. The can feature upto 16 banks of memory and require a 288-Pin DIMM connectors which would be available on the new X99 chipset motherboards. The DDR4 memory controller offers Quad channel memory support. DDR4 would offer faster clock speeds and the Haswell-E platform supports frequencies o 2133 MHz, 2667 MHz O.C +.

LGA 2011-3 Socket Supports Haswell-E Processors

Intel is also preparing the latest LGA2011-3 socket which has similar dimensions but a different ILM key pattern which allows only for Haswell-E processor compatibility. Intel adds compatibility for both their Channel DRX-B Liquid cooler and T-HPHS air cooler with the LGA 2011-3 socket for Haswell-E processors.

Better Overclocking Support For Overclockers

Just like Haswell and Ivy Bridge-E before it, Haswell-E  retains the great overclocking features that  ship with the “K” series and “Extreme Edition” processors. Both the memory and processor can be overclocked beyond limits with unlocked turbo limits, unlocked core ratios in 80/100 increments, programmable iVR voltage, support for XMP mode, unlocked memory controller and voltage limits, native support for memory upto 2667 MHz, Unlocked PCH and PLL voltage controls and more. A single Haswell-E processor would feature 2 x16 and 3 x8 Gen 3 PCI-e support with 40 lanes and would be directly connected to the DDR4 memory controller and the Wellsburg X99 chipset. The feature set would remain the with technologies such as SSE4, AVX, VT, AESNI under its belt.

Intel Core i7-5960X “Haswell-E”

Intel's First Native Eight-Core Processor

The Intel Core i7-5960X Extreme Edition is the be the flagship processor of the lineup boasting 8 Cores and 16 threads. The Haswell-E Core i7-5960X will house 2.6 Billion transistors inside its 22nm die and measures at 335.2 mm which is considered a huge die. The die block diagram also shows that the Core i7-5960X is not a 12 core die as previously expected which turns out to be a Xeon core. We can see 8 Cores with a large amount of shared L3 cache in the middle with a DDR4 memory controller at the bottom and Queue, Uncore and I/O at the top side. This would be Intel’s first 8 Core consumer processor and would be clocked at 3.0 GHz base and 3.5 GHz boost frequency. The processor would feature 20 MB of L3 cache, 140W TDP and support for DDR4-2133 MHz memory. Being the flagship processor of the Haswell-E lineup, the Core i7-5960X would end up with a price of $999 US.

In terms of raw performance, the Core i7-5960X is around 20% faster in terms of 4K Video Editing, 32% faster in 3D rendering and 14% faster in games and AI processing compared to the last generation Core i7-4960X CPU that is the flagship Ivy Bridge-E offering. The models will be available with Intel’s TS13X liquid cooler which has been in the market since the first generation of Sandy Bridge-E processors and is priced in between $85-$100 and compatible with LGA 2011-3, LGA 2011, LGA 1366 and LGA 115* platforms.

Intel Core i7-5930K Processor

The Core i7-5930K is the second best processor of the flock featuring 6 cores and 12 threads. Featuring a clock speed of 3.5 GHz base and around 3.7 GHz boost, the Core i7-5930K would integrate 15 MB L3 Cache and a TDP of 140W. The processor would be able to support DDR4-2133 MHz memory. From specifications, the Core i7-5930K looks a lot like the current generation Core i7-4960X processor however we are looking at better IPC due to the improved Haswell microarchitecture. The price forthe Core i7-5930K would be $583 US at launch.

Intel Core i7-5820K Processor

The Core i7-5820K is the the entry level processor of the lineup featuring 6 cores and 12 threads. The CPU comes with a 15 MB L3 Cache, 3.3 GHz base clock, 3.6-3.8 GHz boost clock, 140W TDP and support for DDR4-2133 MHz memory. Being similar to the Core i7-5930K in terms of technical specifications aside from the clock speeds, the Core i7-5820K might just become an attractive processor for the X99 chipset platform since it will be priced at $389 US. There is one limitation however that the processor features only 28 PCI-Express lanes which compared to 40 PCI-E lanes on the other two processors is skimmed down however, the processor would be able to cope with 2-Way and 3-Way SLI setups easily.

        Gigabyte X99 UD7 WiFi - Unboxing

        The first thing we notice of the board is that it comes in the standard box packaging which we should expect from a high-end motherboard. The board weighs a bit more than standard motherboard which is due to the extra components found on the X99 motherboards. There's an easy carry handle on the top while the front side of the box displays a large Ultra Durable logo with a shied in the background. Gigabyte has three X99 lineups which include Gaming, Overclock and Ultra Durable.

        The back side of the box is once again the standard design which we should expect from companies these days with a ton of marketing material and feature details. A large specifications and feature map lists down each component of the motherboard and its I/O panel in detail. From the feature bar, we can see that Gigabyte has emphasized a lot on four key features; Performance, Durability, Protection and Looks on the X99 UD7 WiFi.

        Just like the Z97X SOC Force we tested a few months ago, the X99 UD7 WiFi has a flip cover which pops out on the front. The flip cover shows the X99 UD7 WiFi shot with its LEDs in action. The X99 UD7 WiFi's heatsinks are LED-backlit and we will detail them in a bit.

        On the other hand of the flip cover, we can see a transparent cut out which shows off the X99 UD7 WiFi in all its glory. It's a nice bit of detail and especially useful when buying the motherboard since you can take a quick peek at the motherboard without having to open up the box.

        The Gigabyte X99 UD7 WiFi is placed nicely inside a cardboard box, we can see that Gigabyte has went with a gold yellow and black color scheme with strikes of silver on the memory slots. The Gigabyte X99 UD7 WiFi is an E-ATX form factoe motherboard measuring at 30.5cm x 25.9cm. It's massive so don't expect to slot in an ATX sized chassis because that would be a recipe for disaster. Nevertheless the board looks gorgeous but before we move on, we take a look at the last major component of the box.

        The accessories are a fun part of any package and motherboards come with a plenty of them. For Gigabyte's X99 UD7 WiFi, we are looking at an LED Lit I/O Panel backplate with a mirror shielding at the front. This is the first time that I am looking at such a design for the I/O shield and it looks amazing. The I/O panel is powered through a 2-Pin connector. We also have six sleeved SATA cables which look gorgeous, a 4-Way SLI, an extended 3-Way SLI, a regular 3-Way SLI, a 2-Way SLI and a 2-Way Crossfire bridge, two antennas for wireless connectivity, a Molex 8-Pin to dual 8-Pin power connector, a Manual Guide, Installation Guide, a drivers CD and the LAN Utility driver disc.


        The X99 UD7 WiFi from Gigabyte can be found below in all its glory, showcasing the impressive design and build quality which it delivers to consumers.

        Gigabyte X99 UD7 WiFi - A Closer Look

        We are finally going to begin a closer inspection of the board but before we do that, let's take one more look at the Gigabyte X99 UD7 WiFi from the front. As we detailed earlier, this E-ATX motherboard is a beast and we are going to verify that in the performance section. There are several components scattered across the PCB such as the large heatsinks and the eight DDR4 DIMM slots.

        The back of the PCB does not include any electrical components but it indicates the several components that are integrated on the front. A large backplate can be found below the LGA 2011-3 socket while there's also a support bracket for the top most VRM heatsink.

        The first thing we notice on the motherboard is the LGA 2011-3 socket (3 stands for the third revision of the LGA 2011 socket). The socket is covered by a protective cover which can easily be removed. The socket should not be removed unless the motherboard is going to be used with a Haswell-E processors otherwise, even the slightest bit of pressure can damage the pins badly.

        Removing the socket cover, we can finally see the glorious housing of the Haswell-E processors. The socket has two levers which need to be pulled to open the socket and is quite tricky for someone who's new to the HEDT platform. A arrow on the top shows the position which needs to be aligned with the Haswell-E processor for proper use. Putting the CPU in any other position will damage the pins and make the board ineffective of use. The LGA 2011-3 socket houses 2011 pins but some manufacturers have released boards which come with more pins that allow better stability and performance. According to Gigabyte, their LGA 2011-3 socket comes with 6x (30u) gold plating which means better connectivity and stability allowing for longer usability without the worry of corroded pins.

        The other major thing about the Gigabyte X99 UD7 WiFi is that it supports DDR4 memory. Each side of the socket is surrounded by four DDR4 DIMM slots making a total of eight DDR4 DIMM slots. The motherboard features support for up to 64 GB of DDR4 memory (8 x 8 GB / 4 x 16 GB) in quad channel mode with speeds ranging to DDR4 3000(O.C.) / 2800(O.C.) / 2666(O.C.) / 2400(O.C.) / 2133 MHz, The motherboard is fully compliant with Intel's XMP 1.3 (Extreme Memory Profile).

        The next thing that comes into detail is the 8-Pin power connector which supplies power directly to the socket. The connector is placed in addition to the 24-Pin ATX connector which can be found to the right socket of the DDR4 DIMMs. The power circuitry which we will detail in a bit provides ample juice to the board and socket for overclocking support.

        The X99 UD7 WiFi is fitted with Gigabyte's AMP-UP Audio solution which is fitted on an isolated PCB which is separated from the rest of the PCB components and indicated by a yellow line which will litup under operation. According to Gigabyte, the AMP-UP audio design features the Realtek ALC1150 Audio codec with 115dB SNR HD Audio and built-in rear audio amplifier. There are ten DAC channels with support 7.1 Channel HD audio play back and 2 channels of independent stereo sound output.

        Gigabyte X99 UD7 WiFi_AMP UP Audio Design

        Gigabyte also makes use of what they call independent right and left audio channel PCB layers. This eliminates per channel cross talk and allows for better audio quality.

        Gigabyte X99 UD7 WiFi_AMP UP Audio 3One of the main features of this motherboard is the design. Gigabyte has used a total of four heatsinks on the X99 UD7 WiFi motherboard which include three for the electrical circuitry around the CPU socket and one for the PCH heatsink which sits near the storage ports. The top most heatsinks are interconnected with a large heat pipe solution which runs the entire surface of the motherboard. This design helps regulate and dissipate heat effectively through load regions.

        The PCH heatsink is not only bulky, but the most impressive of all four heatsinks. It comes with a Gigabyte logo engraved on the top in a metallic design, covered with Gold Yellow, Matte black and Brushed Aluminum black colors. The Yellow strikes on the heatsink are back lit which give out a nice effect when under operation.

        You can note in the following picture that the PCH Heatsink also uses a two-pin power connector just like the I/O shield to light up the LEDs. These small LEDs add up to the looks and aesthetics of the board showcasing Gigabyte's effort that went into designing this board.

        There are a few overclocking features that can be found on the X99 UD7 WiFi, the bulk of which can be found on near the ATX power connector. These include an onboard power button, Single BIOS / Dual BIOS mode switch, onboard restart button, onboard clear CMOS button, Direct to BIOS button, Debug LED display and an OC PEG connector which delivers extra power to the PCI-e graphics cards.

        Several voltage points can also be spotted in this OC section which can be used by enthusiasts and overclockers to have a real time display and analysis of the voltages being supplied to the motherboard for easy tuning. Do note that the X99 UD7 WiFi being the Ultra Durable oriented motherboard doesn't pack the OC panel which we have came to see on the Overclock series which include the Z97X SOC Force and X99 SOC Force.

        Storage options include 10 SATA 6 Gbps ports and one SATA Express port. Gigabyte has limited the SATA-E connectivity to just one port because there are also M.2 slots which need to be powered up for use. There's still a good amount of storage options for enthusiasts.

        Next up, we have the two M.2 ports which are available on the X99 UD7 WiFi. One of the M.2 Socket is used for SSD support delivering full 10 GB/s data transfer speeds with the latest M.2 NGFF SSDs.

        The other M.2 socket is placed directly beneath the top SSD one and is already configured with an onboard WiFi and Bluetooth 4.0 card or module for wireless connectivity.

        Gigabyte has added support for both NVIDIA SLI and AMD CrossFire Multi-GPU support. They have featured 4 PCI-Express 3.0 x16 slots and three PCI-e 2.0 x1 slots.  Upon closer inspection, it can be seen that only two slots conform to the x16 lanes while the rest of the two are x8 slots. Gigabyte has mentioned that the allow full 320 GB/s bandwidth when all three or four slots are occupied. In four way operation, three slots would operate at x8 while one slot will operate at x16 while in 3-Way, two slots will operate in x16 and one in x8 mode. Gigabyte achieves this with an onboard external clock generator.

        Gigabyte X99 UD7 WiFi_PCI-Express slotsThe WiFi module has two cables running through the surface of the board which connect to two Antenna connectors. This offers wireless connectivity which includes WiFi and Bluetooth 4.0 functionality.

        There are two key components found beneath the PCH heatsink. First two are the front panel connector slot and two USB 3.0 front panel headers. These allow for four USB 3.0 ports to operate at any given time when connected.

        The second components are found to the left of these ports which include two front panel USB 2.0 headers, SPDIF connector, two system fan connectors and a front panel audio connector.

        Gigabyte X99 UD7 WiFi_Audio USB 2.0

        Now, we take off the heatsinks off the motherboard to show what else is under the hood and there's a lot more. First up, the PCB is all black which is a good thing since the brown PCB color is just awful. This is a 2oz copper PCB which makes use of two times more copper layers that provide better power savings, lower PC temperatures and better overclocking performance. The humidity protection feature protects the PCB from corrosion and increase its usability life.

        The most important thing which comes under this area is the PWM section. Gigabyte has resorted to a 8-Phase IR Digital PWM design which also features IR Powlrstage ICs. The fourth generation IR Digital controller deliver precise power delivery, more precise current sensing and distribute the thermal load between each ICs to prevent overheating. Gigabyte has used Server Level chokes from Cooper Bussman which deliver high-grade and long lasting efficiency with the added bonus of all black solid state capacitors rated at 10K hours. The board uses a single package IR MOSFET design which saves space and delivers much more power in overclocking then regular multi-chip designs.

        The DDR4 DIMMs also come with their own VRM and electrical circuitry with two phases dedicated to each side of the DDR4 slots. This enables better delivery and enhanced stability when operating in XMP modes and 3300 MHz + overclocked specifications.

        The X99 PCH is one big chip when compared to Z97 mainstream PCHs. The size of the X99 is even larger than a Kabini SOC which we are going to test in an upcoming review. The majority of the features which X99 delivers have already been detailed at the top of this review.

        Below, you can take a look at just how massive the heatsink is when removed from the board. There are four heatsinks which are all interconnected with each other to offer better thermal load management.


        The X99 UD7 WiFi is finally installed with our Core i7-5960X Extreme Edition processor and we are just a few more nifty details away from testing out this beast.

        Finally we have a few more shots which you can see below in the gallery and next up, we move towards the performance testing of the X99 HEDT platform.

        Overclocking Intel’s Core i7-5960X "Haswell-E" Processor:

        Overclocking on the i7 5960X was pushed to 4.25 GHz with a multiplier of 34 and a BCLK speed of 125 MHz. The overclocking itself was rather difficult at first given how everything is tied to the BCLK. Furthermore, the chip is a hard clocker and only a few chips can achieve 4.4 GHz. Our chip was unable to push to 4.4 GHz without giving several crashes or being 100% stable hence we resorted to a lower overclock configuration. Nevertheless, 4.2 GHz for the 8 Haswell cores is pretty good. We used G.Skill's Ripjaws 4 DDR4 memory kit which is clocked at a good 3000 MHz. You can find the review of the memory kit separately at

        Power Consumption and Thermals

        The Gigabyte X99 UD7 WiFi might not be advertised for overclocking but its built quality is easier to reflect the overclocking potential it houses under the hood. Though higher overclocks mean higher power consumption for which high quality PSU’s are recommended, it also means better performance to break records and better gaming performance. The stock results of the Core i7-5960X are pretty high compared to mainstream chips due to a 140W TDP but its under the regular wattage which we may expect from an HEDT chip. Haswell is tuned to deliver much more efficiency in terms of consumption and the difference between an 8 Core Haswell-E and 6 core Ivy Bridge-E is nominal. Overclocking changes this with the Haswell-E pushing a lot of power to its central core.

        On the temperature side, we saw that the Haswell-E Core i7-5960X  pushed around the 81-83C even with the top-end air cooler available in the market (Phantek’s PH-TC14 PE). With such high temperatures under over clock configuration, a water cooling setup is recommended for 24/7 overclocked usage.


        With Haswell-E and X99 tested, I would like to say that I am thrilled with the time I spent analyzing the new platform. From the 8 Core Godzilla which Intel has released, to high performance motherboards and DDR4 memory kits, this has got to be one of the most biggest platform launches in recent years. We are not only looking at a new processor or a new motherboard lineup, we are looking at a change in the entire PC landscape.

        Starting with the Gigabyte's X99 UD7 WiFi motherboard which is a terrific high-end product built for enthusiasts and overclockers. Gigabyte has added all of their top-of-the-line features on a single PCB which has resulted in a monstrous board with tons of features, utilities and overclocking potential. The price will be a factor but for a HEDT platform, a flagship product does come with a higher price tag but for the price, the X99 UD7 WiFi is a brilliant motherboard which has all the goodness in a single package and there's nothing about it that I didn't like. For overclockers who think that the motherboard has a few options for them, Gigabyte has the X99 SOC Force which you should look into and offers a slew of overclocking features configured on its OC panel.

        The LGA 2011-3 socket is here to stay for a while and it wouldn't be soon when Broadwell-E comes to the market next year and Intel will add support for them on the same chipset and socket which exists in the market today. The Haswell-E keeps the price structure same as last year's Ivy Bridge-E, starting off with the entry level $389 US 5820K, $583 US 5930K and the $999 US 5960X. We have so far tested two of these chips, the 5930K and the 5960X. The 5930K is an absolute beast of a processor with performance outmatching the fastest Ivy Bridge-E processor. If the 5930K has to be regarded as a Godzilla, then the 5960X is easily the daddy of Godzilla being Intel's first 8 Core consumer chip with tons of multi-threaded performance at hand. The $999 US price will take some heavy commitment to the HEDT platform to get hands on but it is what it is, a fast processor for a heavy price. The Core i7-5820K is an entry level option for those who want to try out the X99 platform and is a good replacement to the Core i7-4790K with 6 cores and higher clocks that result in better IPC performance.

        The price of the platform is a major factor, the chips and memory are very expensive since this is the first generation of these products and the HEDT platform amounts to a little percentage of total desktop PCs. It would take a year before the DDR4 adoption rate catches up with Skylake generation of processors next year but for those who want to try it now can grab it now. Do note that Broadwell-E will end up being compatible with the same motherboards and memory so it would be wise for budget level buyers to stick with the 5820K and grab a faster Broadwell-E when it hits next year. The X99 motherboards are priced adequately with major board manufacturers offering decent solutions for under $250 US too. Overall, the X99 platform is a sight of the future of next generation desktop PCs across the board. It's a platform built for enthusiasts and delivers on that promise with several key innovations and technological support making it one of the biggest simultaneous tech launch in the Desktop PC industry.
