The Vishera Review: AMD FX-8350, FX-8320, FX-6300 and FX-4300 Tested

General Use Performance
We'll start out our tests with the 7-zip benchmark, a CPU bound multithreaded integer workload that looks at 7-zip compression/decompression algorithms where the IO subsystem is removed from the equation:
7-zip is almost the perfect scenario for AMD's Vishera: a heavily threaded integer benchmark. Here the FX-8350 is able to outperform the Core i7 3770K. In fact, all of the Vishera parts are able to outperform their price competitive Ivy Bridge alternatives. The old Core i7 920 does pretty well here thanks to its 8-thread architecture.
Next up is Mozilla's Kraken JavaScript benchmark. This test includes some forward looking js code designed to showcase performance of future rich web applications on today's software and hardware. We run the test under IE10:
If the 7-zip benchmark is the best case scenario for AMD, Mozilla's Kraken test is among the worst. Largely dominated by single threaded performance, the FX-8350 is significantly slower than a Core i3 3220. Only Intel's old Core i7 920 is slower here, and that's a chip that debuted in 2008.
Although not the best indication of overall system performance, the SYSMark 2012 suite does give us a good idea of lighter workloads than we're used to testing.
Overall performance according to SYSMark 2012 is within striking distance of Ivy Bridge, at least for the FX-8350. AMD seems to have equalled the performance of last year's 2500K, and is able to deliver almost 90% of the performance of the 3750K. It's not a win by any means, but AMD is inching closer.
Par2 File Recovery Performance
Par2 is an application used for reconstructing downloaded archives. It can generate parity data from a given archive and later use it to recover the archive
Chuchusoft took the source code of par2cmdline 0.4 and parallelized it using Intel’s Threading Building Blocks 2.1. The result is a version of par2cmdline that can spawn multiple threads to repair par2 archives. For this test we took a 708MB archive, corrupted nearly 60MB of it, and used the multithreaded par2cmdline to recover it. The scores reported are the repair and recover time in seconds.
Crank up the threads and once again you see Vishera do quite well. The FX-8350 outpaces the Core i5 3570, and the FX-4300 falls only slightly behind the Core i3 3220.

but at least priced decently. Replyleexgx - Tuesday, October 23, 2012 - link
still like how AMD think they have 8 full cores in there (some sites list the Modules not FP cores in their lists)8x is 4 Modules (4M/8T)
6x is 3 Modules (3M/6T)
4x is 2 Modules (2M/4T)
they hardly outperform stock clocked matched cpus (that they listed) Reply

also to add if you own an Bulldozer (or Vishera) type of cpu you should all ready have these patches installedhttp://support.microsoft.com/kb/2646060

There are 8 fully pipelined integer cores in there, they are just very weak. Some of it is the shared frontend/decoder some of it is the integer execution units themselves. Weak SIMD/FPU-performance isn't the only thing it got. It just does so much less. You don't have two pipelines with separate resources to achieve SMT/HT. They need wider execution here. Preferably dropping the shared front end thing too. Makes no point of having it around, focus on making it faster and dump all that cache which does no good. Mobile/Notebook chips can't really have 16MB of cache any way. Just a few MB. ReplyDDR4 - Wednesday, November 07, 2012 - link
It's just a marketing thing, the cores don't have that much power, AMD's just looking to do better than Intel in one area. ReplyHomeles - Sunday, October 28, 2012 - link
Because performance = core count. Brilliant. ReplyCeriseCogburn - Tuesday, October 30, 2012 - link
You know, you look at this crap amd chip in the review, and then it hits you... hardYou can lock sandy b 2500K at 4,500.00 mhz all day long on every motherboard out there, all 4 cores, with no voltage increase, w the crap stock intel fan for years on end, never a hiccup, and smoke the every living daylights out of everything amd has.
I mean, I find it very interesting that with videocards we STILL hear about overclocking, but when it comes to cpu's, suddenly all the OC fanboys of amd fall dead freaking silent on the matter.
Sorry, just cannot help noticing when the wannabe emperor is stark naked and moments ago his glorious worshippers were pointing and admiring and swooning over just how fast the amd jaybird can run when pushed, and then.... suddenly, the MASTER OC CHIP OF ALL TIME, the Sandy Bridge... is rather ignored... and the naked jaybird streaking thing becomes the dejected peasants silence...
Really sick of it man. Really sick of it. Reply

Oh look, it's the highly ignorant fool CeriseCogburn...You make demonstrably false statements on every single AMD article and merely provide further proof of your ignorance. Honestly, if you're unable to find anything better to do than post idiotic comments on every anadtech article, I have a suggestion: EDUCATE YOURSELF, LITTLE DIPSHIT. Reply

Dude, seriously? Did you know the current world record for overclocking is held on an AMD processor? AMD is incredible when overclocking, especially super cooling, yes it may be a bit slower than Intel, but damn you can't beat AMDs price.You're a bit of an idiot mate. Reply

think about this..which one is better an eight unlock cores as AMD called it.
or 4 cores with hyperthreading technology?
4 cores with hyperthreading it will act like an eight cores because single core will act like two cores as claimed by intel but bear in mind there would be a mathematical complex going on behind intels hyperthreading. but WHAT if you unlock this thing so it would go freely to eight cores as claim by AMD?
THAT IS THE REASON WHY AMD HOLDS THE WORLD RECORD FOR OVERCLOCKING BECAUSE THEY MANAGED TO UNLOCK THIS THING.
IF INTEL WILL PRODUCE 8 CORES CPU..THEN AMD WILL MAKE 16 CORES..AND THEN AMD STILL WIL BE THE WINNER FOR WORLD RECORD..
ON THIS POINT OF VIEW JUST BE OPEN MINDED.
DO NOT ACT LIKE YOU REALLY SICK WHEN ITS NOT BECAUSE YOU WOULD MAKE YOURSELF LIKE TWICE MORON AND TWICE IDIOT.
JUST TAKE AN ADVICE FROM G101. EDUCATE YOURSELF.
I USED TO BE AN INTEL USER.. BUT WHEN I'M BEGINNING TO UNDERSTAND THIS TREND..I WOULD LOVE AMD AS THEY LOVE CONSUMER'S POCKET (AGAIN- BE OPEN MIND. ITS MY OPINION) Reply
