Introduction

Intel or Chipzilla as we know it is the largest company in manufacturing semiconductor computer processors. Starting from 2006, Intel unveiled their Tick-Tock model which aims to deliver a new generation CPU architecture each year. If we look back then, that Intel was launching their 65 nm Core 2 Duo series and six years later the company introduced Ivy Bridge their first 22nm CPU. The “Tick” and “Tock” in Intel’s model represent a specific architectural change and die change in the new generation core processors. A Tock represents a totally new CPU architecture while a Tick represents a die shrink of an existing architecture. Ivy Bridge architecture was a Tick since it carried over the same architecture from Sandy Bridge and shrunk it down to 22nm. Today, Intel is unveiling a new Tock, a new architecture, one which brings massive changes and revamps the way Intel thinks how processors should be built.

Today, Intel launches their much anticipated fourth generation core processors codenamed Haswell. The Haswell micro-architecture carries new architectural changes while carrying over the 22nm architecture while improving its efficiency. The Haswell generation of core processors are compatible with the 8-series Lynx Point chipset and the socket LGA 1150 motherboards. Today, we will be reviewing the Intel Core i7-4770K and Intel’s DZ87L-75K motherboard but before we talk about the products themselves, first we have to look into the architecture that powers them.

Haswell Architecture Insight

As previously mentioned, the Haswell architecture makes use of 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 Lynx Point 8-Series PCH (Platform control hub). The 8-Series chipset is featured on the LGA 1150 socket motherboards with which Haswell processors are compatible.

The Haswell die is largely similar to its predecessors Ivy Bridge and Sandy Bridge. The Haswell die comes with up to four cores which share the same L3 cache. It features 1.6 Billion transistors and a die size of 177mm2. The Ivy Bridge die featured 1.4 Billion transistors in a 160mm2 die. A large portion of the die is dedicated to the Intel’s HD graphics in Haswell processors which also shares the same L3 cache. Other than these, the Haswell die include system agent, display agent, Memory controller I/O and PCI-e 3.0 memory controller. 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 processors would provide a nice overall improvement as far as x86 performance is concerned but the bulk of advancements lie inside the 4th generation HD graphics core. The reason behind Intel pushing graphical power other than IPC improvements is mainly due to AMD pushing the graphics processing boundaries with their APUs which with the current HD 7000 series cores offer improved visuals compared to Intel’s HD 4000 offerings on Ivy Bridge. With Haswell, Intel wants to change the game and they are making several HD graphics chips for various tiers. The HD 4600 or GT2 graphics chip would be fused on most of the Haswell mobile and complete desktop line up. There are also faster GT3 variants but would be limited to low-power and desktop R-series which can be seen here. We will discuss more about the HD 4600 GPU in the article later on.

Haswell Block Diagram

We already detailed the Haswell die above, what you see below is the block diagram for Haswell platform. You can see that the processors is directly connected to the Lynx Point PCH through DMI 2.0 and FDI. The PCH offers USB 3.0/USB 2.0, SATA 6 GBps (Native), High definition Audio, VGA, integrated LAN, PCI-e 2.0, TPM 1.2 and Super IO/EC.

Haswell Overclocking and Power Management

Intel’s fourth generation Haswell core would feature Integrated voltage regulator “FVIR” and enhanced BCLK overclocking. Board manufacturers today offer a wide variety of products which help drive overclocking needs for consumers and enthusiasts.

Intel’s Haswell 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  upto 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.

For power management, Intel has developed new C-States such as C6 and C7 while Speedstep which is naively enabled would adjust frequency, core voltage based on user workload. Available C-State would differ on various SKUs.

Nomenclature

Intel’s new processor will get a numerical naming scheme; 47xx, 46xx, 45xx and 44xx. The 47 and 46 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.

Haswell 8-Series “Lynx Point” Z87 PCH

Intel’s Haswell processors would be compatible with the 8-Series “Lynx Point” chipset fused on the LGA 1150 socket motherboards. There are different tiers of Lynx Point chips on the Haswell platform which include Z87 /Z76/H87/H81/B85/Q87/Q85. The motherboard we would be testing today is based on the Z87 PCH. The 8-Series chipset in a whole isn’t much different from 7-Series Panther point. The following chart mentions key differences between both platform control hubs:

Item 7-Series “Panther Point” 8-Series “Lynx Point”

Intel Core i7-4770K – The Flagship Haswell CPU

Intel Core i7-4770K is the processor we would be reviewing today is the flagship part for Haswell generation of processors. The Core i7-4770K sticks to the four core and eight thread design we have been looking at since i7-860 “Lynnfield” and i7-920 “Bloomfield” however features a new microarchitecture design compared to them coupled with faster clock speeds. One of the main reasons behind not fusing more cores in their mainstream LGA lineup is the lack of competition from rival AMD. AMD has an 8 Core CPU but it lacks the horsepower to compete against Intel’s flagship parts.

The Core i7-4770K is clocked at 3.5 GHz base and 3.9 GHz Turbo and features 8 MB of L3 cache. The TDP has gone up from 77W “Ivy Bridge” to 84W “Haswell”. The FVIR “Fully integrated voltage regulator” and a boosted graphics core is the main reason behind the wattage increase but it still is lower compared to the power gushing Sandy Bridge-E 150W TDP and Piledriver 125W TDP parts. The processor we have is and ES sample with the C0 revision, stepping 3.

The Core i7-4770K features a boosted graphics core codenamed “GT2” and labeled HD 4600. The HD 4600 core packs 20 execution units with a clock speed of 1250 MHz which drops down to 350 MHz in idle mode. It has 2 ROPs and 4 TMUs and packs enough punch to run most of current generation games with low-medium settings. But it doesn’t matter since most of the buyers would probably have a discrete GPU solution to run their games and would hardly ever use the HD 4600 chip.

Intel DZ87KLT-75K – The Last Intel Motherboard

Since the Core i7-4770K chip is only compatible with LGA 1150 socketed boards, Intel sent us another product in their review kit. The DZ87KLT-75K motherboard is the latest from Intel featuring the Z87 chipset and LGA 1150 socket to support Haswell processors. Before going into detail, i’d like to mention that the board would also be the last which Intel manufacture’s on their own. Don’t worry though since partners of Intel would keep on making their own motherboards while Intel focuses on more important tasks. Following is the official statement by intel:

We disclosed internally today that Intel’s Desktop Motherboard Business will begin slowly ramping down over the course of the next three years. As Intel gradually ramps down its motherboard business we are ramping up critical areas of the desktop space including integration of innovative solutions for the PC ecosystem such as reference design development, NUC and other areas to be discussed later.

The internal talent and experience of twenty years in the boards business (which until recently has been largely focused on desktop tower type designs) is being redistributed to address emerging new form factors — desktop and mobile – and to expand Intel’s Form Factor Reference Design (FFRD) work and enable our partners to develop exciting new computing solutions.

The Desktop segment continues to be a major focus for Intel with hundreds of products across many subsegments and applications. Intel expects the broad and capable DT motherboard ecosystem (ie Asus, Gigabyte, MSI and many others) to fully support Intel’s growing roadmap and large worldwide customer base. Intel’s Desktop Motherboard Business will not develop any new Intel branded desktop motherboards after completion of Haswell-based 4th gen Core launch products in 2013 and will continue to support all products sold through the warranty period included with the specific product.

Intel remains very committed to the desktop business. We are making significant investments in the enthusiast platform with our K SKU portfolio and new 3rd Gen Intel Core Extreme Processors. In fact, Intel’s roadmap includes 227 desktop SKUs at 34 different price points, offering desktop solution for a wide range of customers… Intel will continue to support a broad portfolio of CPUs, on 3 different sockets, including LGA 2011, LGA 1155/1150, and BGA parts for entry level platforms. We maintain a broad portfolio of desktop products, covering 5 different power envelopes. Future product roadmaps will be evaluated based on platform performance and power needs.

Unboxing the DZ87KLTT-75K Motherboard

Back to the board itself, the DZ87KLT-75K falls under Intel’s Extreme series brand featuring the cool Extreme series skull logo on the packaging and heatsink. The front of the cardboard package has a black design with a theme similar to the Haswell CPU package.

The back of the box provides labels to the key components and features of the Intel motherboard. It comes with three years warranty, SLI, Thunderbolt, CrossFireX support. You can also see the new Visual BIOS interface for easier overclocking that we will detail later in this article.

The motherboard is packed inside a anti-static sheet with both ends held by thick polyfoam sheets. It ensures that the motherboard isn’t damaged while carrying the box.

Below the motherboard are a variety of accessories that come with the package. These include a Bluetooth 2.1/ WiFi 802.11 b/g/n module, backpanel plate, front header USB cable, 2-Way SLI connector, integration guide and the most coolest accessory which is a bundled mouse pad with the extreme series skull logo. I have always been a fan of the skull logo and its nice to see Intel providing enthusiasts with an additional cool accessory free of cost.

Finally, we take a look at the motherboard itself. The DZ87KLT-75K comes with a black and blue design theme. It features the LGA 1150 socket and Z87 chipset.

There are two set of heatsink on the VRMs which have the Extreme series skull and Intel logo embedded on them. The motherboard features an 8 Phase VRM for smooth power delivery to the CPU socket powered through an 8-Pin connector.

Four DDR3-DIMM slots offer supports for upto 32 GB of memory with native speeds of 1600 MHz and 2400 MHz O.C+. We can also spot Power On/Off and Reset switches near the memory slots.

The motherboard comes with 6 native SATA 6 GB/s ports and two SATA 3 GB/s ports. The motherboard supports Raid 0,1,5,10 modes.

Expansion slots include three PCI-e 3.0 x16 slots (electrical; x8/x8, ; x8/x4/x4). There’s also three PCi-e 3.0 x1 and a single PCI legacy slot.

The PCH sits beneath a large heatsink besides which lies a mPCIe connector which can be used for expansion card such as Wi-Fi or MSATA SSDs. There are two Debug LEDs located beneath the motherboard.

Near the top and lower section of the motherboard lies two superior phase shedding technology which helps keep the system performing in the most efficient state. It also tells the status of the VRMs through LEDs.

The I/O panel include various connectors such as a PS/2, 8 USB 3.0, Back-To Bios Switch, Dual GIgabit Ethernet LAN ports, 10 Channel high definition audio, Thunderbolt connector, Firewire and a HDMI switch.

Cooler Compatibility With LGA 1150 Socket

While Haswell processors ship with their own boxed coolers and cooler makers providing retention brackets for LGA 1150 compatibility, it should be noted that LGA 1150 socket is easily compatible with both reference LGA 1150 boxed coolers and custom products.

So if you’re upgrading from LGA 1155 to LGA 1150, you can easily equip your cooler on the latest socket from Intel without any sort of troubles.

It should be noted that due to improvements in 4th generation core processor power efficency, the requirements for the processor’s power supply have also been altered. Intel reccomends that the users running the Haswell cpu platform check the list of tested PSUs for ones capable of supporting fourth generation core processors. The list can be found at: http://www,intel.com/go/powersupplies/.

From the filters at the top right of the page, set 12V2 Min Load 0A to “Yes” to see which PSUs have been found to support the processor’s new power requirements. By default, the DZ87KLT-75K BIOS disables “Lowest CPU Idle power setting”. To make use of the power supplies that meet the 12V2 Min Load 0A, you have to enable the “Lowest CPU Idle power setting”. This option is located under the power tab section and you must set the “Intel Dynamic Power technology” to custom in the primary power settings section in Visual BIOS.

HD 4600 “GT2” Benchmarks

3DMark 2013

While 3DMark 11 was a success, 3DMark from Futuremark further pushes the boundaries of benchmarking utilies going all out with cross platform support which include Windows, Windows Phone, iOS, MAC and even Android. The utility comes with three benchmark tests configured for different tiers of high-performance PCs, Mid-range PCs/Tablets and smartphone devices.

3DMark 11

Futuremark released 3DMark 11 in 2011 bringing support for the latest DirectX 11 GPUs at that time. Since then, the benchmark tool is used widely for evaluating performance of high-end PCs.

Resident Evil 6

Capcom brings the horror back to the screens with their blockbuster Resident Evil 6 title which was well received among the community. The game features three playable campaigns which include Leon, Chris, Jake and downloadable content for Ada Wong.

Tomb Raider

The Tomb Raider franchise was rebooted this year with the latest title in the long running franchise. The players start off their journey with a younger and under-trained version of Lara who goes off on her first survival action journey.

GRID 2

Grid 2 is the sequel to the highly successful racing game – GRID. While the game runs great on graphic cards, the developers have also optimized their coding for the latest Haswell processors with fourth generation HD graphics core which features AVX2/AVX and DirectX 11.1 support.

Batman: Arkham City

The second title in the Batman: Arkham series has also been developed by Rocksteady Studios. Batman: Arkham City takes place in (isn’t it obvious by the name?) Arkham City which is infested with all the super-villains and their minions which Batman has previously met past his journey.

The game was released on PC in November 2011 and runs on the latest Unreal Engine 3 which features rich DirectX 11 detail, tessellation and PhysX support for NVIDIA cards.

Power Consumption and Thermals

The power consumption of the Haswell chip are slightly higher compared to its Ivy Bridge predecessor. The TDP is 84W for the 4770K compared to the 77W of the 3770K.

The reason behind this is the large GPU core and dedicated VR module which helps deliver better performance and stability. Overall, we are looking at the same consumption rate as Ivy Bridge with improved performance. A downside is that the temperature issue from Ivy Bridge has also returned which results in higher temperatures when more voltage is supplied for overclocking. We used a relatively high end cooler – Phantek’s PH-TC14 PE with Triple fans and Junpus Nano Diamond Thermal Greases which work absolutely great for overclocking. We have a detailed article on both these products and overclocked Haswell at 5 GHz incoming for you to feast on but for now have a look at the temperatures. You can see the temperatures for yourself in the charts below:

Conclusion

Finally, we come to the conclusion for Intel’s 4th generation Haswell architecture. The first thing to note ios that the PC landscape is definitely shifting with consumers focusing towards low power, efficient and portable products. Haswell is built keeping these things in mind, for mobile and all-in-one solution it is a win win situation but things are different on the desktop LGA platform where consumers look and aim for power adn performance.

The Intel Core i7-4770K is currently the fastest Quad core processor in the world. It beats its Ivy Bridge based predecessor but not by the kind of margin people expected from a Tock. Coming to the Tock, which is essentially a new architecture in Intel’s year over year roadmap and Haswell while didn’t focused more on core improvements is definitely a Tock keeping in mind the tons of changes made to the core which include a near SOC design, improved performance per watt and a GPU core that aims to satisfy most of the desktop crows except the enthusiast and hardcore gamers.

Intel’s Core i7-4770K which is another quad core in the company’s flagship line of CPUs is not largely different from its 3770K predecessor. The quad module core is a reason why consumers and most definitely the enthusiast crowd would be disappointed from the 4770K and the fact that the heating issue somehow still exists on the platform due to low quality TIM between the IHS and CPU die. At the same time, it would spark some interest for overclockers since the 4770K retains all the overclocking features of the LGA 2011 platform and brings it to the mainstream LGA 1150 platform. The board themselves are quiet interesting this time around with the likes of Z87 XPower, Z87X-OC Force and Z87 OC Formula and many more which give an imitative to consumers to lean towards this feature packed platform.

The HD 4600 core while not enticing for the hardcore gamer crowd who rely on discrete graphics solution is something which Intel should be credited for given the fact that it improves the performance of Intel’s built in GPU bringing it on comparable levels to the Trinity HD 7000 GPU from AMD. The GT2 with its new AVX2 instruction set and full DX 11.1 support is a massive boost while the Iris and Iris Pro (Not available on desktops) takes the performance of iGPs to the next level.

So the question that comes to everyone’s mind after reading this lengthy review is, whether i should get Haswell or Not?

The answer is quiet simple, if you are coming from an older architecture based platform such as LGA 1156 or LGA 1366, then expect massive improvements with the latest Haswell architecture. If you are using a Sandy or Ivy Bridge processors, then there’s no need to buy Haswell because the performance gains you will get would be medicore. For overclockers, Haswell is something to look forward to, the features of LGA 2011 and overclocking are all there at a much less price range. Do make sure to grab some pots of LN2 since Haswell is just as hot as its older brother Ivy Bridge.

In short, Intel’s Core i7-4770K boosts performance to the next level bringing improved CPU and GPU speeds that bring a tons of feature for overclockers and enthusiasts.
