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 eggsFx octobeast

Pros: 8 cores (see other thoughts for a fun rant about this lol).
Multi tasks like a champ
This cpu is like a v8 turbo diesel truck engine (powerstroke ftw). It is not the fastest out there but it can handle any load that your standard gamer or home 3d or video renderer will do with plenty of room to spare.
the 8320 and its "bigger" brother the 8350 are the best overall bang for your buck in raw cpu power. If you are a comfortable with over clocking go with the 8320, but if not go with the 8350. They are identical in all areas aside from the clock speeds they come with out of the box. Not that you really need it to be any faster than it is out of the box in my opinion. Runs all my games like butter at max settings at perfectly playable to obscenely high fps paired with my r9 270x which is overclocked to 1100mhz. I have worked with the fx 6300 (which I put in my brother's build) and the 8350 which is in one of my friends builds. All of them are very solid cpus.
The 8350 out of the box scored a slightly lower than a stock i7 3770 for a good chunk less! (do the math I would tell you how much it is but I dont want that to scratch my review as it would be including "prices/avaialblilty"
Cinebench revision 15
i7 3770 score: 662 this score was provided to me by the sofware itself I didnt get to test this one, all the other ones I tested 5 times and took an average of them.
8350@4ghz: 636
8320@3.5ghz: 556
Comparison to i5 series: 489 (3570 specifically which is VERY similar to the 4670 in performance aside from the new Haswell power saving features etc): which is priced comparably to the 8350 when it is not on sale.

Cons: 32nm tech. This is getting very outdated I hope amd will release a new fx line based on their 28 nm tech that is being used in their new apu line. Intel is at 22nm currently and plans to be at 14 by december 2014!
For those of you who dont quite know what this means, an intel cpu at 22nm clocked at say 3.5 ghz is comparable to an amd 32nm cpu clocked at 4 ghz. This means a bit more power usage and heat.
If you are gaming this is really irrelevant because there is no real gain in investing in faster ram speeds than 1333mhz (SPECIFIC TO DISCRETE GRAPHICS CARD USERS), but this line of cpus is not going to be able to handle some of the redonculous ram speeds some of the intel cpus will be able handle.
The stock heatsink provided will work, but I wouldn't use it. Idle with the stock heatsink is between 35-40 and that was enough for me to get an aftermarket cooler. I didn't want to see its max temps under load. Bought myself a cm hyper t4 brought my idle temps to 25-30 degrees C. Just factor some kind of aftermarket cooling into this if you want to fully push this thing without being worried about shortening its life span.
Lastly this will "limit you" to pci 2.0 slots for expansion, not that it really matters ( the story may be different if you plan to do 4k but that is not in my area of expertiese. 1080p is plenty for me. also if you plan to do 4k I would guess your budget allows for a bit fancier cpu and you arent hunting for the best performance per dollar, as much as you are hunting for sheer performance.

Other Thoughts: Ignore anyone who says it is only 4 core with 8 threads they only looked at what windows task manager showed them. There are in fact 8 cpu core modules, they just share cache memory per 2 cores which makes it read as 1core with 2 threads x4. They do this because it makes the cpus run more effieciently then the preivious version of this line the fx X1X0 such as 8150 or 6100 otherwise known as bulldozer.
Maxed out settings (aside from anti aliasing and games that require 3gb of vram) on:
Assasins creed 4
Tomb Raider- Benchmark provided with the game gave me 40 fps on average with vertical sync on. (60hz 1080p tv)
Crysis 3-
BattleField 4 and 3-
Watch dogs-
World of tanks
Sniper Elite 2 and 3
Starcraft 2 (this was the only game the 8320 “struggled with” at stock settings because sc2 only utilizes 2 cores)
League- max fps of 360 so far ahah
Another thing start discounting the idea that games only use 4 cores. That is changing rapidly and I expect it to become more and more common for games to recomend 8 threads. Xbox 1 and ps4 both have 8 core cpus. Watch dogs in my opinon just needs 6 cores minimum on the amd side. Games that I know of at the time of writing this review that can use 8 threads or more recieved a hyphen (-) aside from league in my list of games maxed.
Hope this reivew helps out alot of people!
My personal build:
Fx 8320
xfx r9 270x 2gb black edition (may upgrade this to a r9 280 or 290 sometime in the future to aquire more vram)
xfx 650Watt psu pro series
gskill ares 1600mhz
gigabtye 990fx motherboard
1 tb wd blue 7200
256gb samsung evo ssd
Rosewill Challenger usb 2.0 version case
Cooler master hyper t4 cpu cooler
Windows 8.1 home premium- I would highly recommend 8.1 btw it boots faster, is a bit more effiecient esp in its usage of multiple cpu cores, although you can fix this in 7 I hear with a patch that is not automatically found in windows update. I may be wrong about that bit however. the info I am using for 7vs 8 in core usage is a bit older from another reiview on newegg and a youtube video that was released before 8.1 was a thing and it was just windows 8.

5 out of 5 eggsAwesome!

Pros: WAY better than the horrible fx-4100 i first bought for my build. Games that were bottlenecked by my cpu were running %100 better coupled with my 270x

Cons: none

5 out of 5 eggsGreat CPU

Pros: > Price, AMD CPU's are great value.
> Overclocks very easily in my Asus M5A99X EVO.

Currently running at 4.2 GHz @ stock voltage :)
I could definitely push it farther. Currently mounted with a ZALMAN CNPS9500A-LED 92mm Cooler.

Cons: None.

Other Thoughts: If you are considering the FX-8350 buy the 8320 instead and just overclock it.

Temperatures with my cooler are fine, I don't hit above 55 Celsius while gaming.

4 out of 5 eggsworks except for the fan

Pros: As powerful as almost anyone would really need it to be (4 Ghz AND 8 cores at max) for quite cheap, especially in comparison to Intel CPUs. Works for anything i through at it.

Cons: The stock fan was extremely loud, so i had to switch it out for a liquid cooling one.

5 out of 5 eggsUnhappy with Next Step up: FX8350

Pros: Ive been running this processor with an ASUS 990X since the week it was released. I switched to the FX-8350 just to see what the difference would be. I honestly have to admit, there is not much. You can overclock the Vishera 8320 to realitive speeds equal to the Vishera 8350 and actually get less heat. Why this is, I do not know. I might just switch back to the 8320 from the 8350 to save money on my A/C bills because, I am cooling it the (awesome) air cooler, Cooler Master Hyper 212 Evo.

So the point is, if your looking for a processor that is cheaper and runs insanely fast and cool (even when overclocked) go with this one instead of the Vishera 8350.

Cons: none

5 out of 5 eggsDoes the job

Pros: Works well w/ multiple apps running simultaneously, and I used a cooler master 212 plus, so the thermals are well controlled on stock speeds. I was playing Crysis 3 on this rig w/ a sapphire 7870 at ultra settings and there was no noticeable drag, screen tearing or stuttering. For the price and the performance, I am thoroughly satisfied.

Cons: Not enough applications take advantage of having sooo many cores and the stock heat sink and fan are essentially expensive paper weights.

Other Thoughts: If you are building on a budget and intend to use an independent GPU, go w/ this CPU.

5 out of 5 eggsFx8320 Great chip!

Pros: It seems to work really well. Fast load speeds, smooth gaming and decent Idle temps. People told me this chip would bottle neck my GPU's (GTX770 4gb sli) but I haven't noticed any drop in performance with dual 1080p monitors. Games max out very easily and this chip seems to keep a steady 60fps with the 2 gpu's. Very pleased with my purchase.

Cons: This chip is a power hungry beast and the stock CPU cooler is just awful. Have you ever wondered what a 80mm fan sounds like at 6000rpm? If you use this chip for anything other that web browsing you will find out. It sounds like a jet turbine spitting out a swarm of angry bees at a sack of cats being beaten by bag pipes! Invest in a after market cooler if you do t want to hear the scream of a banshee while playing your AAA game or watching a movie.

5 out of 5 eggsalmost better than i7 4770k

Pros: overclocking to 4.5 ghz is easy and safe, An no oc fails with the stock volts(4.668 is the highest/Not safe) if you look around an know what you're doing, you could oc to 5.0 ghz an be slightly better than a i7 4770k (high-med motherboards recommended for oc). I can run any game on high/ultra @1080p with a gtx 660 msi oc (1.2ghz). this cpu is really good for video editing and streaming, an everything else.

Cons: none.

4 out of 5 eggsAMD FX-8320

Pros: Fast
8 Cores

Cons: Not as fast as I was expecting
Runs pretty hot
Fan kind of loud
Locking lever for cooler broke during installation

Other Thoughts: I'm running this processor on an Asrock Fatal1ty 990FX board with 8GB Ripjaws 1600 and a 2GB XFX 7850 Black Edition. I have not overclocked anything, although the FTuner overclocking software that came with the mobo states the processor is running at 3697mhz.

Rips through everyday multitasking

FPS in demanding games I've tried with it have not been what I was expecting. 30-60fps ARMA 3 maxed out with no AI. Add AI and the framerate drops as low as 12fps depending on the amount of AI and action on the screen. Other less demanding games run without a hitch, though, and I have yet to try any of my other games yet.

I used Arctic Silver and temps are still not the greatest. In a super cool, air conditioned basement with an ambient temp of about 18c, the lowest the CPU has idled is 37c and reaches temps of 50-53c during gaming. Normally idles around 40-43c, idling at 44c as I type. Will definitely be buying a better cooler in the future, probably go water cooled.

Side note: my case has some pretty extreme airflow with 6 120mm fans, so the heat issue is not because of the case.
