  • 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).

4 out of 5 eggs

Pros: Decent speed for price.

Cons: Very very hot. An aftermarket cooler is a must. Stock cooler will not keep up at load with gaming.

Other Thoughts: Have stayed away from AMD CPU's for over 15 years after problems in the late 90's. This one seems better, but not sure worth the few dollars savings vs a i5.

5 out of 5 eggsBest Bang For Your Buck CPU

Pros: - Fast, even at stock speeds. I've never once had this choke on me.

- Because I don't overclock, I've never had this CPU go much higher than 40 C under load. Then again, I'm using a Hyper 212 fan/heatsink.

- Very good price:performance ratio.

Cons: - Very power hungry in comparison to similarly spec'd Intel CPUs.

- Pathetic stock fan/heatsink. I didn't even bother using it. May as well just chuck it once the package is opened.

- Doesn't make me breakfast.

Other Thoughts: I've been using it in conjunction with two Zotac GTX-560 graphics cards running in SLI. Almost everything I've played was in High settings, with a few in Ultra (!!). Had no noticeable problems with framerates or graphic hiccups, and the only time heat was a problem was with my graphics cards while running TERA Online. I plan to upgrade my graphics card as soon as I can afford it, though.

3 out of 5 eggsLooks great on paper

Pros: - Can be fast when it's not lava hot
- 8 cores for multitasking
- Cheap
- Easy install
- Only uses 125W

Cons: - Lava hot. 55-65 degrees celcius + on stock cooler. 45-60 degrees celcius when paired with arctic silver 5 and 212 EVO aftermarket. Looks like a liquid cooling system is needed. Did not expect my 139.99 investment to become a 200 dollar + investment. Would have just bought an I-series.
- Stock heatsink is so loud that it could be heard on the floor below me.
- FPS drops, although I'm not deducting an egg based on the fact that I believe it is my R9 280x causing the drops (issue existed with old i7, which prompted me to upgrade my CPU.)

Other Thoughts: My case is a very large case with six case fans and good air-flow. It bothers me that my age-old i7 860 performed similarly at lower temps on a stock heatsink. On paper, the FX-8320 destroys that CPU, but for me it hasn't. So disappointing, I wanted to give AMD a chance.

3 out of 5 eggsA letdown

Pros: - It can be fast
- It's really cheap
- 8 cores

Cons: - Runs REALLY hot, even on aftermarket cooler (Hyper 212 EVO) and arctic silver 5 thermal paste. Seriously. On stock cooler it was running at 55-60 degrees Celsius. With the 212 Evo it's running at 45-50 degrees celcius. I'm probably going to have to upgrade to liquid cooling. If I knew I was going to put up with this much heat, I'd have just paid extra and got an i-series processor.
- Performance is pretty inconsistent, but I'd probably gauge that to the poor cooling.
- I replaced my motherboard and CPU, my CPU was an i7 860 and I expected a huge increase in performance. In benchmarks, I notice. In everything else, including gaming, I don't.

Other Thoughts: My case has pretty good airflow, and every single fan in it is on and working. I've done no overclocking, it's just stock everything.

5 out of 5 eggsAmazing CPU

Pros: If you don't want an Intel, this is a perfect processor for your gaming needs.
I got this instead of the FX-8350 because I can just overclock this one to 8350's speeds and beyond if I need to.

Cons: The heatsink is terrible, but that's to be expected from all CPU's that come with a stock fan. It's too hot for the bundled heatsink, however.

Other Thoughts: This has gotten me high and ultra settings on most games (paired with a good graphics card, of course). Shame about the heatsink that's just laying around though.

5 out of 5 eggsNow an AMD guy

Pros: -Cheap
-8 Cores
-Overclocking ability

Cons: -Lower single-core clock

Other Thoughts: Honestly, I was an Intel guy. After buying this because I wasn't willing to spend twice the price for Intel I have no regrets. In 5 years 8 cores will be the norm, and the processor has plenty of room for a higher core clock.
Some people say it's bad at gaming but I have an opposite experience.

Running a 750ti with this processor I get 45-55 fps on GTAV Very High settings at 1080p. So don't listen to the people saying it's not good for gaming- because it is. (That's stock, too). If you have the money to spend $400 on a processor, I'd say go for Intel. But if you don't have that much just sitting around being wasted then definitely go this processor. You won't have any regrets!

5 out of 5 eggsVery good Price to performance CPU.

Pros: Can game very well at 1080p and play most modern games well paired with a GTX 970, most games today uses the GPU more than the CPU, so a beefy GPU will go further than a CPU.

Vulkan API and DX12 will bring multi-core optimization to everyone. This would literally bring the FX line to compete with the i7s. Look to multi-core benchmarks and games to see how.

Also if you do lag in Battlefield or get pesty microstutter look to CPU unparking. It would solve the issue.

Cons: Very hot, and a power hog. But with the money I saved over intels the difference would take a little over 5 years.

5 out of 5 eggsFast.

Pros: This is by far the best deal on a CPU I've had since the Phenom II chips were new. I own multiple i7 (4770, 4790) chips which were over $300, this chip right out of the box on stock voltage was able to hit 4ghz, I was able to get it to 4.4 ghz with only a tiny voltage increase and suspect it would do well at 4.6 - 4.8 for a heavy OC. Granted these have a lower IPC than Intel, for the price and a mild OC this easily gives fantastic performance per dollar. I really was not happy with the Bulldozer architecture but these later chips really push them to great performance.

Cons: Not a con at all but if you are looking to build a brand new rig, keep in mind that this is the end of the line for AM3+, AMD will be releasing AMD4 socket boards with their new Zen architecture next year. This chip was an upgrade for one of my rigs still running Phenom on an am3+ board. For people who don't need the cutting edge however, this chip will likely hold up for quite a few years before any major GPU bottlenecks start creeping in.

Other Thoughts: I may have been lucky with my OC but it seems that these are the same bin as FX 8350 chips (stable at 4.0 GHZ on stock vcore). I'm glad I grabbed the 8320 and saved a few more bucks.

5 out of 5 eggsExcellent buy!

Pros: Easy installation, no hassle, no errors

Cons: None that I've seen so far.

Other Thoughts: I installed this with the appropriate motherboard. I anticipated have to take all night to get it to work but on the very first start up it went straight to Windows on an existing hard drive. Thumbs up.
