New microarchitecture, new level of performance

Piledriver microarchitecture, a tuned-up Bulldozer, has finally reached the flagship AMD FX processors (the new FX series processors are codenamed as Vishera) for improved performance and better energy-efficiency. Up to eight “Piledriver” cores ensure unrivaled multitasking and pure core performance. The AMD Turbo Core technology pushes your core frequencies to the most when you need it most. To top it off, like all other AMD’s Black Edition processors, the new AMD FX 8-core Vishera processor black edition is unlocked for fabulous overclocking* capability.  Unrivaled performance is not the only trick AMD has up their sleeve. Vishera processors are at a reasonable price point. (*AMD’s product warranty does not cover damage caused by overclocking even when overclocking is enabled via AMD Overdrive software.)

  • newegg New Piledriver microarchitecture Piledriver microarchitecture is the second generation of AMD Bulldozer microarchitecture. The internal core structure has been modified for higher frequencies even without any changes in the manufacturing process. Piledriver has a more precise branch predictor and a larger instruction window with ISA extensions FMA3 and F16C. The execution units acquired an enhanced scheduler and learned to process individual instructions faster, such as integer and floating-point division. And Piledriver microarchitecture delivers higher power efficiency compared with Bulldozer microarchitecture.
  • newegg Unlocked AMD FX processor with 8 Piledriver cores The native 8-core desktop processor delivers unrivaled multitasking and pure core performance with the new Piledriver microarchitecture. 32 nanometer die shrink was designed to reduce leakage for improved efficiency, increased clock rate headroom and better thermals. The AMD unlocked technology offers more headroom for your overclocking (AMD’s product warranty does not cover damage caused by overclocking even when overclocking is enabled via AMD Overdrive software.).
  • newegg AMD Turbo technology The AMD FX Processors come equipped with AMD Turbo CORE Technology, a performance boosting technology that helps increase performance on the applications that need it the most.
  • newegg Amazing instruction capabilities Like Bulldozer, Piledriver has some amazing instruction capabilities. Advanced Vector Extensions (AVX) increase parallelism tailored for scientific and 3D applications that use heavy floating point calculations. Floating Point Vector Multiply-Accumulate improves throughput and performance on many vector functions (integer and floating point). Advanced Encryption Standard noticeably increases performance on the latest encryption applications like TrueCrypt and benchmarks like PCMark.
  • newegg AMD Hypertransport technology HyperTransport Technology (HT or HTT) is a high-speed, low latency, point-to-point link which helps reduce the number of buses in a system thus reducing system bottlenecks and enabling today's faster microprocessors to use system memory more efficiently in high-end multiprocessor systems.
  • newegg Integrated DRAM Controller with AMD Memory Optimizer Technology AMD FX Vishera Processor features a high-bandwidth, low-latency integrated memory controller that supports faster and low voltage memories and provides new Pre-Fetcher improvements and direct communications to each core in Dual-Core module (APIC registers in each core).

5 out of 5 eggsSolid performer

Pros: One of the best price:performance ratios available today. Runs at perfectly manageable temperatures with a closed-loop water cooler.

Cons: I did not use the stock fan, but it does not look substantial enough to properly cool this processor. Does not effect score since I didn't actually test it.

Other Thoughts: I have this processor in my media and video transcoding server. I upgraded from an i5-661 and I was expecting a modest increase in transcoding performance, but I was blown away when I measured a 293% increase. This is certainly due to my software being integer heavy and supports over 8 simultaneous threads, so don't expect this kind of performance in every scenario. However, I doubt I could have found a higher value purchase for my server.

5 out of 5 eggsVery nice CPU!

Pros: No installation issues.

I am using the "stock" fan that the CPU came with. The system is not going to be overclocked, and I also added two additional fans to the top of the case, so I won't have any heating issues. The systems been on for about 30 hours now, and the system temp is in the normal range.

Cons: N/A

Other Thoughts: For the first 48 hours, I'm going to have an MPEG set as the desktop just to keep it busy.

5 out of 5 eggsGood CPU, Fair heatsink fan

Pros: + Excellent price-performance ratio
+ Wonderful performance on multi-threaded tasks
+ Stock heatsink is equipped with heat pipes and is made by Cooler Master.

Cons: - Stock heatsink is equipped with a super thin, 80mm fan. Under low loads it's fine but when being pushed it gets loud, not unlike an optical drive spooling up to max speed and staying there. If I didn't know better, I might assume that's just how these things are. However I do know better, and I know this thing is LOUD under load.

Other Thoughts: Windows 7 Experience Index score: 7.7

Cinebench v11.5 CPU score: 6.01

Compare that to scores from:
Athlon II X2 of 1.77
Athlon II X3 of 2.54
Intel i7 960 of 5.7
Intel i7 3930K of 10.29

5 out of 5 eggsPerformance on a budget

Pros: + Cheap 8-core CPU for $150 (at the time I bought it on sale)
+ Overclocks like a champ
+ Nearly comparable to an i5 in gaming performance for less.

Cons: - Hot
- Power hungry
- Stock fan that comes with it is horrible. Small and sounds like a jet taking off with 6000 RPM and doesn't keep it very cool.
- Need to 'unpark' cores in Windows 7 for most performance

Other Thoughts: This is a very good CPU for the price, probably the best price/performance above $100. It is good if you want to use it for a virtual machine as, unlike unlocked Intel processors, you get features for shared access to hardware. However, I cannot recommend this enough: get a separate heatsink. The stock one is embarrassingly loud and horrible at cooling. I'd recommend CM's Hyper 212 EVO (what I use) or Corsair's H50i liquid cooler.

Overall, if you want a good processor now for the price, get this. Otherwise, I would wait for the next high performance FX or A series from AMD, whenever that may be released.

5 out of 5 eggsSo far, So good!

Pros: So far, I've seen remarkably fast speeds. I just built a new computer using this 8 Core FX Processor as it's CPU, and so far I can say I'm not let down.

I know what you're thinking, how can I even tell if all these reviews are real? Trust me, I am as real as they get! haha.

Cons: 8 Core needs better cooling, so don't use stock cooler, upgrade like I plan on doing.

Other Thoughts: My other thoughts would be... Have fun if you get this? hah.

5 out of 5 eggs

Pros: Fantastic value, great performance for the money

Cons: ran a little hot on start-up when I had the stock cooler installed.

Other Thoughts: Temperature not really an issue, I planned on upgrading the cooler to a Cooler Master 212 EVO anyways, I just had the stock one on for a quick install to see if my system would boot into BIOS. successful on that so I will continue from there. Great little chip.

Pros: strong CPU no matter what your computer is designed for. included fan/radiator block is sufficient at stock settings, when installed properly. includes pre-applied heat transfer paste.

Cons: none

5 out of 5 eggsLove this processor

Pros: if i could give it 6 stars i would. I went from an intel chip to this AMD chip and for the money there is no comparison. The 8320 has been fast and flawless. At this point i dont see going back to intel any time soon. The processor is also easily overclocked as well. This is a function that is not available in intel at this price point. It is my understanding that you can take this thing to 4.2 G to 4.5 G without issue.

Cons: It runs hot as all AMD's do. Cooler Master EVO 212 takes car of this issue for just over 30 bucks so this con isnt really a con at all considering to get the same performance from an intel your going to pay about $100.00 more.

5 out of 5 eggs  works...IT WORKS

Pros: It's cool, the fan is quiet, all 8 cores are running at expected frequency. Don't try to overclock without an aftermarket cooler, I get stable enough temps and don't need to push it unless I can cool it. GET IT.

Cons: None so far.
