  • 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 eggsGood mid range CPU

Pros: - 8 cores
- $140
- No bottleneck to my GTX 780
- Runs even better when using Linux compared to Windows 10
- OC to 4.2ghz without touching voltage
- Cool case sticker

Cons: - Slower than intel at single threaded performance
- Compared to my i5 4690k, they are about the same with multi threaded performance even though my i5 has half the core count
- Old and outdated
- Multi-threaded performance is less than desirable
- Heat sink is trash

Other Thoughts: Overall this cpu is great for its price. It's a huge upgrade from my old fx 6120 that really sucked. The 8320 with a 780 runs War Thunder maxed out at 60 fps. Don't use the stock heat sink it's worse than Hillary Clinton.

1 out of 5 eggsWorst Processor I've ever bought

Pros: I liked the price tag.

Cons: This piece of garbage processor isn't worth ten dollars. I have gone through two of these things. The first one would run so hot that it would literally shut down my computer. I have the H100i cooler on it, by the way. I finally got a replacement unit, and this one is shutting down my computer as well. I even put the cool and quiet settings on and did everything else in my power to cool this terrible excuse for a processor down. I've swapped out everything else, and I know its the processor. AMD is the worst company to buy processors from, and from here on out, I'm going all intel. Don't waste your money, don't buy AMD. Go intel, its worth the money.

5 out of 5 eggsOverclocked right out of the box

Pros: Worked perfectly without any issues. Installed a third party cpu cooler and overclocked easily to 4 ghz as advertised without any stability issues. The CPU cooler that comes with it is a decent construction and better than the stock coolers of the past.

Cons: None

Other Thoughts: works great

5 out of 5 eggsGreat upgrade from FX-4300

Pros: - Fast Multi-threaded performance
- Very easily overclocked
- Won Silicon Lottery

Cons: - Stock heatsink & fan are not worth it

Other Thoughts: First off, you absolutely do not need to buy the FX-8350 to get more performance. They ARE the same processor with different default clock speeds (and different results of the silicon lottery). I have mine overclocked to a decent 4.2GHz (the same speed as the 8350's Turbo mode) without raising Voltage and I know I can get the clock up to higher speeds but 4.2GHz is perfect for me right now. I definitely feel that I have won the silicon lottery if I can get 700MHz out of the processor without increasing the Volts (My mobo set the volts unusually high though so I actually had to lower the Volts. It defaulted to 1.44V or something above 1.4V).

It is stable with 4.2GHz @ 1.344V.
You will have to buy a new heatsink if you want to Overclock this CPU though.

With an aftermarket heatsink idle CPU Core temps are around 24-28C and under 100% load from Prime95, CPU Core temps are around 56C.

5 out of 5 eggsLove it

Pros: Noticeably fast upgrade from my OC'd Phenom II 945. The shot in the arm my gaming system needed, for a great price. Was looking at Intel options (I was going to need a new MB too), and this was a much, MUCH cheaper alternative while delivering what I was looking for.

Many people are saying this thing runs hot, but not in my experience. I did not use the stock cooler at all (I never do), and paired it with a Hyper TX3, which you can get for just over $25 in some places. Have not tried overclocking yet, but at stock the thing never touches 50 C in Prime95, and actually dips into the teens (!) when idle. Impressive considering I don't live in a cold area. Untested during Summer months though; we shall see.

Cons: None off the top of my head.

Other Thoughts: Overall great choice if you're using it mostly for gaming, but not looking to pay what an i5 setup costs. If you plan on doing video editing or other multi-thread tasks, even better.

5 out of 5 eggsBest CPU for price performance point

Pros: Easily overclockable to over 4GHz(with better cooling can even push close to 5GHz). 8 cores, as detected by CPU-z. Comparable to similar gen i5 in game performance during benchmarks by a certain tech channel (just look up amd fx 83xx vs i5). It outperforms the i5 in games and applications that properly utilize more than 4 cores(i5 4 cores vs AMD FX 8xxx and 9xxx 8). The i5 only beats this CPU in single core performance, and that doesn't really matter because most programs nowadays use more than one.

It's also much cheaper than any i5 out there! The Intel motherboards are also more expensive (albeit usually higher quality) raising the price that much more.

The heat sink area which touches the CPU is made out of copper with copper heat pipes leading out.

I'm able to multitask big time with lots of tabs and programs open, not even losing much performance. Loading times on everything are great paired with an SSD (and probably would only be several MS slower on a standard HDD).

Cons: Not the most power efficient, though over the course of the year with normal usage, this won't amount to more than $10-$20 on your bill compared to Intel. Make sure you have a reliable PSU with enough watts if you plan on getting a powerful GPU. Stock cooler fan is loud(can get VERY loud if you put on a heavy load) and sub-par, but the heat-sink itself is good. You can replace the fan but I recommend getting something likea Cryorig H7 or Hyper 212 Evo which are both relatively silent and something you can overclock at ease.

Other Thoughts: I see a lot of people writing that they got this for their budget build.

For a true budget build I recommend getting one of the AMD APUs as you can usually run one of those in crossfire with a standalone GPU(you can start out with the APU and get the GPU later if you're short on money). Most games nowadays utilize the GPU significantly more than the CPU.

This is proven by many tech sites/videos where they take a relatively weak CPU and pair it with a powerful GPU to still get very high frame rates. It is much better to have a top of the line GPU paired with a mid-range or even low CPU than the other way around for any graphical related tasks.

Also, you shouldn't have to push very hard at all to put on this heat-sink, if you do, you're doing it wrong! simply re-position and balance the clamps better. Be careful when you're removing the heat sink if you're using your own thermal paste as it can glue to the CPU and pull out the CPU with the lock bar still positioned down. Twist and turn it and pull softly.

5 out of 5 eggsGreat Processor!!!

Pros: Very Very fast even today after 4 years old

Cons: Runs extremely hot!

Other Thoughts: This Processor after 4 years is still extremely fast!! I had to buy a bigger heat sink as the one that came with it was not sufficient in keeping it cool. But the build i put this in 2012 is still top of the line.

5 out of 5 eggsFantastic core count for the $$, throwaway fan.

Pros: -Fantastic performance and number of cores for this price point

Cons: -Stock fan is loud, seems insufficient for the CPU. If it is 125W TDP, it probably shouldn't come with the same stock heat sink as what comes with the 65W, 95W options. Either add a bigger heat sink and charge more, or remove the heat sink entirely, save the customer $ in cost and shipping.

Other Thoughts: Using it for a home VM Server, gaming VM. Works very well.

4 out of 5 eggsGreat card! But go for the 8350.

Pros: This CPU is great! i stole it from my parents new desktop and gave them my old one.
This CPU with my 770GTX run everything i put on it at high/very high settings, with lowest of 40 fps.
in WoW i get any where from 60-170 fps. games i have played on with this on high settings, witcher 3, fallout 4, gta V, numerous online MMOs, i wont be upgrading this amy time soon, seeing as i simply dont need to.

Cons: The CPU heatsink was terrible, and actually broke on me. i replaced it with corsair h100i water cooling from bestbuy for $100, temps never go past 40. its wonderful! and has increased my performance.

Other Thoughts: great card, but id go with the 8350, similar price and more performance
