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.)

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.
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.).
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.
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.
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.
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).

N/A 5/22/2013 10:26:43 PM Tech Level: 5/5 Ownership: 3/5 Verified Owner	Rating: 5/5Great Am3+ processor Pros: cheap fast cost to go from 8120 to 8320 was next to nothing! if you have a am3+ motherboard that support this processor swap it out with this! Cons: None Other Thoughts: Steamroller around the corner. Did you find this review helpful? Thanks for the valuable feedback you provided!
N/A 5/21/2013 2:19:32 PM Tech Level: 5/5 Ownership: 2/5 Verified Owner	Rating: 4/5Feels so stable Pros: Fast. Very overclockable. Eight Core Scored 1K more on 3DMark11 physics than my old 1090T. Comes in a nifty aluminium box. Cons: Scored 0.3 less in Cinebench than my 1090T both at 4GHz. Stock cooler runs pretty hot. Other Thoughts: The overall 'feel' seems more stable than my 1090T.

Makinbacon 5/21/2013 1:42:23 PM Tech Level: 4/5 Ownership: 1/5 Verified Owner	Rating: 5/5Just some info that you need to know. Pros: See other comments. 8 Core CPU, Vishwera technology. above 3ghz. Watch the video on the overview tab. Cons: New egg shipping. New egg changed their shipping. Other people complaining about the heatsink. Other Thoughts: Ignore the rating. First off they ship the CPU with a basic Heatsink this CPU is marked for enthusiasts. If you watch the video on the overview tab it explains that. Also that most people who buy this will have bought a after market cooler for it. New egg is offering free shipping now on most products if your willing to wait. and 3 day shipping has gone up for standard items. Went to buy some SATA cables and Arctic Silver and total shipping for $10 worth the items was $8. This is a disappointment to me. Will review the CPU in another post.

Cyphris 5/17/2013 9:57:59 PM Tech Level: 5/5 Ownership: 4/5	Rating: 4/5Nice 1 AMD Pros: Extremely good price/performance. I got this for a new "Scorpius" platform build. Processor is pretty fast, almost as fast as some of the midrange i7's I've had. Cons: Processor runs pretty hot, your looking at 46c. That's using the stock heatsink/fan + a nice even layer of artic silver 5 thermal compound. Pretty hot but looking at other reviews the idle temps seem to be around 42c. Ambient temp might have had something to do with it but doubt it seeings its only 22c inside. Other Thoughts: Most definetly should consider getting a 3rd party cooler as it seems to run a bit hot idling. I'm sure its fine but to me seems a bit higher than it should. 0 out of 1 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
N/A 5/16/2013 5:51:27 AM Tech Level: 4/5 Ownership: 4/5	Rating: 5/5Amazing Budget CPU Pros: -AMD budget pricing -Works in older socket 939 (check motherboard support) -8 "cores" -Simple O.C., running 4.2 Ghz on stock voltage -Media encoding Cons: -Power consumption compared to Ivy Bridge Other Thoughts: Upgraded from a Phenom II X4 Black Edition at 3.8 Ghz, and this 8320-Vishera excels by 30+% across the board. Handles my HD media encodes, 720p, DTS-HD audio, in under 32 minutes. Boot up time with SSD around 12 secs. No more hiccups during heavy gaming with intense physics engines. Lower power consumption compared to my Phenom quad core. Overall, excellent upgrade, works with my Socket 939 890GXM-65 chipset, easy overclocking, and lots of power! 0 out of 3 people found this review helpful. Did you?

Yoderizer 5/14/2013 12:16:34 PM Tech Level: 3/5 Ownership: 2/5 Verified Owner	Rating: 5/5Great CPU Pros: Fast. Runs very cool @ 3.5 GHz. Stock fan is quiet without OCing. Cons: It seemed as if I was going to break the latch when I was installing the stock cooler. Other Thoughts: Stable OC @ just over 4GHz with stock cooler. The CPU fan is a lot louder at these speeds. WEI score 7.8 in Windows 7. 1 out of 1 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
ZeypherUndellus 5/13/2013 9:44:15 PM Tech Level: 5/5 Ownership: 4/5	Rating: 5/5 Pros: Look at the other reviews. This is the best CPU money can buy. Seriously, you can't get a better bang for your buck. It's overclockability is breathtaking (granted you have the required headroom to do it). The Prime95 tests are handled well at stock and overclock. It works in conjunction with the 990FX chipset (duh). It has 8 cores (Which can be turned off all the way down to 2 active cores [think of all the energy saved!]). Easy to install; a fine piece of silicon to game, work, socialize (although you should opt for something less if that's your goal). Cons: Some say they want pizza to come with this thing, others want a new car. I wanted a purple unicorn that talks and can do magic, and it didn't come with one (such a dissapointment). Other Thoughts: BURN. IT. IN. Prime95 for about three hours, let it sink into the depths of your motherboard and let it have fun with its new family. Overclock if you wish. serve with a side of bread. Feeds All and then some.

Computer Repair LV 5/8/2013 1:59:32 PM Tech Level: 5/5 Ownership: 1/5 Verified Owner	Rating: 1/5Failure Pros: none Cons: I am a Tech of 15 years. This is the 2nd processor I have RMA'd, each one failing the MP symmetry tests. Maybe AMD had a bad batch and hoped no one would notice. For anyone who doesn't know how important the MP symmetry is, look it up before you purchase. Never had any other problems with AMD ever. 0 out of 4 people found this review helpful. Did you?

N/A 5/5/2013 12:29:35 PM Tech Level: 5/5 Ownership: 2/5 Verified Owner	Rating: 4/55-egg CPU, 2-egg cooling Pros: Price, performance, better than other CPUs I checked at the same price point, better than my old i7 920. Cons: Day 2 and the stock heatsink and fan have outlived their usefulness. Installing them was harsh, too tight of a fit. There's a little lever made just for the purpose of tightening it, but that lever is almost useless because even in its "open" position THE PARTS DO NOT FIT and required more brute force than I wanted to use on a new CPU and motherboard. Now the fan makes noise. It's cool enough under load but sounds ridiculous. I probably bent something trying to force it into place, and hopefully that accounts for the noise. Other Thoughts: If you're not going to use the stock cooling anyway, count my rating as a 5. 0 out of 1 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
