Introduction

When Intel released their Nehalem architecture based on the 45nm process in 2008, AMD knew that they would once again be left trailing behind Chipzilla in their race to secure x86 performance dominance. A year later, AMD went ahead to release their own 45nm Phenom II processors which came as a surprise with AMD offering triple and hexa core processors within affordable price ranges but it still sparked less interest for consumers.

AMD knew that their K10 architecture just wasn’t upto the job so the company went all out to prepare a new line of FX processors up from scratch that would feature improved IPC over the older K10 architecture and would also deliver for the first time upto 8 cores to consumers. It should be noted that from 2009 till their release in 2011, AMD released nothing other than refreshed Phenom II core processors so that their R&D team can research on the new Bulldozer architecture.

After four years of wait came the most hyped about CPU platform ever in the history of computing world. Fans around the world were waiting for the moment when AMD would finally take the lead over Intel and offer them a true enthusiast platform to driver their needs. AMD’s Bulldozer is the first major architectural change in the company’s history since 2003 but did the new architecture live up to the hype or not?

AMD FX Makes a Comeback With Bulldozer Architecture

AMD made a comeback to the long forgotten FX brand with their new and improved Bulldozer architecture that’s based around a 32nm SOI process by Global Foundries. It features a die size of 315mm2, 1.2 Billion transistors and upto 8 core modules which was an update over the Sandy Bridge’s 995 Million transistors but located in a smaller die measuring 216mm2. The transistor count was first reported to be 2 Billion but it was later revealed that the total transistors available within the die were only 1.2 Million, the die size remained the same.

So coming to the architecture, the FX Processors come with two cores per modules with each CPU consisting of upto four modules that amounts to eight cores. These are two extra cores over the Phenom II architecture that featured 6 cores. Each module comes with 2 MB of L2 cache while a FX Processor features 8 MB L3 cache. The Fetch and Decode Logic is shared by both integer cores located within a single module, these fetch and decode the x86 instructions into AMD’s internal format and send it towards the scheduler for execution. Coming back to the L3 Cache, AMD says that they won’t remove their FX processors from it though it is only useful in server work loads. An APU such as Trinity is deprived from the L3 cache since its a cost effective product which doesn’t need to make use of the extra available cache on the Bulldozer-E “Piledriver” module.

The bulldozer core comes with its shared FPU “Floating Point Unit” that consists of Dual 128-bit FMAC pipes, Dual 128-bit packed integer pipes, PRF-based register renaming and a Unified scheduler for both threads. Each core also comes with its own Integer Scheduler, Instruction Retire, L1 Data Cache and L1 DTLB as detailed above. The latest FX-Processors based on the Bulldozer core feature the latest instruction set which include  SSE 4.1 and 4.2; 256-bit AVX, -256-bit YMM registers, -Non-destructive source operand capability, -AES subset, -FMAC subset (AMD 4-operand form); XSAVE state space management; XOP Instructions. This is a huge update over Phenom II which lacked SSE4 and AVX support.

AMD released a few more slides that year which detailed the performance of their upcoming processor architecture releases such as the Piledriver (2012), Steamroller (2013), Excavator (2014). All of these bring 15-20% IPC improvement over their predecessors. The FX-Zambezi which is the codename for the desktop platform would later on go ahead and fused in the Interlagos and Valencia based server processors within AMD’s Opteron 6300 series chips. The integral architecture of the new processors would be carried over from the desktop parts.

AMD Turbo Core and Power Management Technologies

AMD has also focused on power efficiency with the Bulldozer architecture by minimizing the silicon area through sharing various functions and components between two cores on a single module. Each module will have its own set of functions cross-shared between two cores hence saving space and power. Bulldozer also under goes an extensive flip-flop clock gating throughout design and the circuits are power gated dynamically to ensure less leakage within the new processors.

Various other power-saving features are added to the design through software/firmware which includes C6 and Low power C1E state that dynamically reduces clock speed when the processor is not being used. Application power management and DRAM power management is also include with the new processors.

AMD Power Management

A new feature introduced with AMD’s FX-Bulldozer processors is the addition of Turbo Core technology that allows the processor to dynamically boost up the turbo core speed for faster clock functionality. The Tech is already available on Intel’s processors starting with Nehalem generation of processors. AMD now brings the same yet improved Turbo Core tech to their processors and it allows them to run beyond 4 GHz clock speed.

The Turbo Core technology on AMD’s Bulldozer processors has improved dramatically since its first yet un-impressive introduction of Phenom II CPUs. With a more robust approach, AMD has now set various points which are configurable by the processor itself to adjust the Turbo Core limit. At base clock, a certain amount of TDP would be available which can be turned into extra clock speed when needed on all eight cores. Now suppose we have an application that doesn’t utilize all eight cores on the processor but instead makes use of four. The CPU would dynamically disable the four extra cores and configure the remaining four cores with the max available turbo core speed which would result in excess amount of performance improvement under demand.

AMD FX-Bulldozer CPU Lineup

AMD’s Bulldozer lineup consists of four FX processors all of which fall in three separate tiers. The high-end FX 8 Core series are labelled as “Black Edition” which feature 8 native CPU cores, enhanced gaming and faster task achieving. Next up are the FX 6 core processors followed by the entry level FX 4 core offerings. All of AMD FX-Processors come with an unlocked design allowing for unprecedented overclocking. The complete lineup is listed below:

Model

L3 Cache 8 MB L3 8 MB L3 8 MB L3 8 MB L3
Launch Price $245 $205 $165 $115

You can note that AMD didn’t only went with the “more cores are better” scheme but also bumped up the clock speeds to new heights. AMD’s CPUs easily reach the 4 GHz mark with turbo core technology although this means higher TDP of 125 W on the 8 core parts compared to 95 W on Sandy Bridge Core i7 processors.

AMD FX-8150 – 8 Cores and 4 GHz Achieved

Today, we will be testing the flagship FX-8150 processor that comes with an Octa-core design and features impressive clock speeds of 3.6 GHz base and 4.2 GHz Turbo. The chip is compatible with the latest AM3+ socket motherboards which will be detailed later on. The CPU comes with 8 MB of L3 cache and has a 125 W TDP. The AMD FX-8150 had a launch price of $245 (Current is $179.99) which made it a direct competition against the Sandy Bridge based Core i7-2500K.

At launch, AMD showed slides which advertised that with the FX-8150 users can save upto $800 on a PC compared to the one which uses Intel’s top dog at that time “Core i7 980X”. The slides they showed also compared the FX-8150 against the 980X in which both CPUs were equivalent of each other however FX-8150 came at a much lower price range.

 

AMD was for the first time not only aiming towards high-end performance users but also targeting gamers with their FX processors since a huge market for their discrete GPU solutions lied there and now they wanted to revisit it with their FX platform. Alot such slides were revealed which AMD thought would spark consumer interest and can be seen in the gallery below:

AMD 990FX Chipset and AM3+ Socket

With the launch of the new FX-Bulldozer platform, AMD released a new socket and chipset. While the previous generation processors have been socket compatible with each other, for instance an AM2 processor can be used on AM2+ and AM3 boards but the AM3+ socket is only compatible with the latest generation of FX processors.

AM3+ boards still come with a southbridge (SB950) and northbridge (990FX). The AMD 990FX chipset is the latest in the stack replacing the 890FX chipset though is alot similar to it. Both chips are directly connected to the AM3+ socket processor that offers a DDR3 Dual channel memory controller supporting memory with speeds of upto 1866 MHz. The chipset adopts the PCI-e 2.0 interface (3.0 isn’t available on 990FX chipset). The SB950 offers up to 14 USB 2.0 ports (USB 3.0 ports are offered through an separate chip), 6 SATA 6 GB/s ports, HD audio, Gigabit LAN and PCI interface.

The AMD 990FX chipset also features SLI multi-gpu functionality on AM3+ motherboards which wasn’t available on 890FX chipset.

A Closer Look At Gigabyte GA-990FX-UD7

Gigabyte ships the motherboard in a large boxed package that’s well featured with marketing logos and details. Both the front and back ends are engulfed with a wide variety of feature logos and details. A front cover can be opened up which reveals the motherboard itself through a clear plastic cut, we can also note the black and grey heatsink theme used on the motherboard.

Inside the cover is a large cardbox package which contains yet another box through which the motherboard can be seen at. Removing the motherboard box reveals another hidden package beneath it which consists of the bundled accessories and manuals.

There are a wide variety of accessories bundled with the motherboard which include an installation guide, User manual, Driver installation disc, 2-Way Crossfire cable, 4-Way SLI connector, 3-Way SLI connector, 2 Way SLI cable, backpanel shield, 2 SATA cables and a Gigabyte logo sticker.

Finally, the motherboard itself is taken out from the box and it may look bigger than a normal ATX sized board due to the E-ATX form factor. The socket AM3+ is colored black since it supports the black edition FX processors. The motherboard should have no problem equipping high-end coolers such as the NH-D14 or the Phantek’s PH-TC14 PE on it. Although liquid coolers are a must if you wish to overclock the 8 Core processors.

A large aluminum heatsink array which makes use of copper heatpipe to dissipate heat runs from the southbridge, all the way up to the 990FX northbridge and ends up at the top most VRM. The VRM and nortbridge sit beneath the larger section of the heatsink while the southbridge is also located underneath a separate heat-sink block.

By removing the heatsink, we can note that the motherboard features a 8+2 Phase power supply featuring Ultra Durable 3 design that offers 2x Copper PCB, Japanese solid state capacitors with 50,000 hours of lifetime, Low rds (ON) MOSFETs and Ferrite core chokes.

These are the features that allow for improved overclocking and stability on the GA-990FXA-UD7 motherboard. The CPU socket is powered through an 8-Pin connector.

There are four DDR3 DIMM slots on the board that support a max capacity of 32 GB of ram in dual channel mode with speeds of upto 2000 MHz O.C+. Right next to the DIMMs, we can spot the 24 Pin ATX connector along with the Power On/Off, Reset and Clear CMOS switches which come handy for overclockers.

For storage, the GA-990FXA-UD7 motherboard includes 8 SATA III 6Gbps ports. Six of the SATA ports are powered by the SB950 chipset while the rest of the two grey colored ports are powered by a Marvell 88SE9172 controller. Right next to the grey colored ports, a SATA power connector is spotted which provides additional power to the PCI-e slots for better stability while using upto 3 or 4 GPUs in either SLI or Crossfire modes. Beneath the black color ports, we can spot a DEBUG LED, fan port, CMOS Battery and the front panel connector along with TPM and USB 3.0 front panel connectors.

Expansion slots include a mighty 6 PCI-e x16 slots and a single PCI legacy slot. Although only two of the PCI-e slots offer x16 functionality while two offer x8 and the remaining two offer x4 functionality. The motherboard offers 4-Way CrossFireX and 4-Way SLI compatibility. As mentioned earlier, the motherboard can be provided extra juice through the SATA power connector when using multiple GPUs.

The I/O is also equipped with various ports that include upto 9 USB ports (2 USB 3.0, 7 USB 2.0), SPDIF out (optical and coaxial), Firewere (Ieee1394a), RJ-45 LAN, 6 Channel audio jack and two eSATA ports powered by the Marvell 88SE9172 controller. The Gigabyte GA-990FXA-UD7 is truly a high end motherboard which is equipped with a wide variety of features and is available for $204.99.

Overclocking the FX-8150

Overclocking the FX-8150 was a fairly easy job, we just had to raise the multiplier from 21x to 23x (200 MHz BCLK) with a voltage adjustment of 1.48V and turbo core disabled across all cores so the CPU reaches 4.6 GHz clock speed. This is a good improvement over the base speed of 3.6 GHz. The FX-8150 can easily reach around 4.7 – 5 GHz overclocked frequencies with better coolers. AMD shipped review samples of their FX-8150 processor with their latest liquid cooler, we didn’t get it with our review kit but our air cooler matches any high tier liquid cooler.

We have included the overclock scores in the charts which are provided in the performance section.

Gaming Performance

FX-8150 – Battlefield 3 Performance

Battlefield 3 is the award winning mutliplayer shooter from EA’s studio DICE. The game features an enhanced Frostbite 2.0 engine that implements DirectX 11 features such as tessellation, dynamic lightning and sub-surface scattering with per particle motion blur. Battlefield 3 relies heavily on graphics performance which is the reason we are looking at minimal differences in performance from each processor in the chart below:

FX-8150 – Elder Scroll Skyrim Performance

Bethesda released their Elder Scrolls Skyrim in 2011 and the hype level shattered the roofs. The game was met with wide success and is built with the latest Creation engine which meant a farewell to the much older game bryo engine from Bethesda. The game has one of the most biggest and well crafted world ever created. The game requires a good CPU for stable performance, most GPUs can handle the game well. It wasn’t until users started pouring in their custom content and mods for the PC version such as high-resolution textures and more which required GPUs with higher VRAM for adequate performance. Skyrim is known as one of the reasons by PC gamers for GPUs with higher VRAM.

FX-8150 – CRYSIS 3 Performance

Crysis franchise is the crown jewel for the PC gamers. Even after going multi-plat, the game is considered to be the most brilliant and gorgeous game ever brilliant, a visual marvel in short. The third and most probably the last title in the Crysis trilogy blends in the most deepest story line of the franchise with graphics that would make any other game cry in shame. Powering the game is the beastly and much user friendly CryEngine 3 that adopts all the features of DirectX 11 API. Simply speaking, the game demands a high performance graphics card than a high performance CPU to play well on higher settings.

Power Consumption

The FX-8150 is built on a 32nm process and comes in a 125W TDP package which is higher than the mainstream processors from Intel. This means higher temperatures and more power consumption which is a major down side for the Bulldozer processors.

Conclusion

You may wonder why it took us so long to review the FX-8150? We received the processor last month and had to cover the Haswell Core i7-4770K first along with Computex 2013 which had put alot of load on me. But here we finally have the Bulldozer review and we thank AMD for giving us the chance to review the FX-8150 with a fantastic motherboard such as the Gigabyte GA-990FX-UD7.

So let’s get to the point, AMD released their FX-8150 two years ago and it was one of the most hyped up chip ever released. The hype went down after people noticed the lackluster performance it featured against Intel’s Sandy Bridge processors at the time and we can see that from the benchmarks posted above. The FX-8150 has given AMD a roadmap to follow but they are still years behind Intel in performance. The power consumption is high and the performance fails to attract the audience. But there are some good parts about Bulldozer too, the chip proven to be a overclockers dream, it overclocked for me easily to 4.6 GHz. The chip can even do 5 GHz with decent cooling and the current world record for the chip sits at 8.8 GHz which is with a doubt impressive.

The chip was priced at $220 at launch but went down to the sub-$200 price range shortly after launch which is good for budget users. It has eight cores which are well for multi-threaded applications although we didn’t see any actual benefit of those cores compared to Intel’s four core offerings. In the end, the FX-8150 Bulldozer was a missed opportunity one which could have been much more than what the end product was. Most of the issues and problems faced with Bulldozer were fixed with the revision of Bulldozer codenamed Piledriver. The review for Piledriver FX-8350 would be published shortly.

Here’s a tilt of hat to the good folks at AMD Middle East, who were kind enough to share a ‘AMD FX-8150 Bulldozer’ and ‘Gigabyte GA-990FX-UD7″ with us and made the review possible.
