The Vishera Review: AMD FX-8350, FX-8320, FX-6300 and FX-4300 Tested
by Anand Lal Shimpi on October 23, 2012 12:00 AM ESTFinal Words
Vishera is a step in the right direction for AMD, it manages to deliver tangibly better performance than last year's disappointing FX processor without increasing power consumption. Thanks to architectural and frequency improvements, AMD delivers up to 20% better performance than last year's FX-8150 for a lower launch price, while remaining within the same thermal envelope.
AMD does manage to pull away with some very specific wins when compared to similarly priced Intel parts. Performance in the latest x264 benchmark as well as heavily threaded POV-Ray and Cinebench tests show AMD with the clear multithreaded performance advantage. Other heavily threaded integer workloads also do quite well on Vishera. The only part that didn't readily beat its Intel alternative was AMD's six-core FX-6300, the rest did extremely well in our heavily threaded tests. Look beyond those specific applications however and Intel can pull away with a significant lead. Lightly threaded applications or those whose performance depends on a mixture of single and multithreaded workloads are typically wins for Intel. The story hasn't really changed in that regard. For AMD to become competitive across the board it needs significant changes to the underlying architecture, some of which I don't know that we'll see until the 2013 - 2014 timeframe. Even then, Intel's progress isn't showing any signs of slowing.
Power consumption is also a big negative for Vishera. The CPU draws considerably more power under load compared to Ivy Bridge, or even Sandy Bridge for that matter.
Ultimately Vishera is an easier AMD product to recommend than Zambezi before it. However the areas in which we'd recommend it are limited to those heavily threaded applications that show very little serialization. As our compiler benchmark shows, a good balance of single and multithreaded workloads within a single application can dramatically change the standings between AMD and Intel. You have to understand your workload very well to know whether or not Vishera is the right platform for it. Even if the fit is right, you have to be ok with the increased power consumption over Intel as well.

LOL - seems like... hahahahhahahah in some imaginary future in a far off land, if and when and only if amd does xxxx and yyyyyy and blah blah blah blah,.... blew it.g101 - Wednesday, November 21, 2012 - link
More extreme ignorance from the idiot CeriseCogburn. Little boys who only game should seriously consider not commenting on things they aren't capable of comprehending.Stupid little bitchboy CeriseCogburn...What a waste of oxygen.

nice to see AMD make better procs and lower their pricesandrewkoch - Friday, November 9, 2012 - link
If you live in an area that requires A/C most of the year like me, the true cost of owning a FX8350 processor is about an additional $100 year vs. owing a 3570k.Fx8350 +15 watts idle +95 watts load vs. i5 3570k
50 hours week light cpu usage = 75W
10 hours week heavy cpu usage = 760w
Combined usage = 1025w @$0.11 Kw/h = $1.12
A/C usage 75%-80% @$0.11 Kw/h = $.84
Extra electrical cost $2/week
Extra electrical cost $100/yearly or $300/3 years
Maybe my math is wrong, but if you use A/C most of the year and pay for electricity an AMD cpu is a waste of money. Then again some people still use incandescent light bulbs instead of compact fluorescent lamps or LED bulbs.

LoL my math was wrong in the above post.Fx8350 +15 watts idle +95 watts load vs. i5 3570k
68 hours week light cpu usage = 1kW
100 hours week heavy cpu usage = 9.5w
Combined weekly usage = 10.5kw @$0.11 Kw/h = $01.15
Average A/C usage 80%*$1.15 @$0.11 Kw/h = $.0.92
Extra electrical cost $2/week vs. owing a 3570k
Extra electrical cost $100/yearly or $300/3 years vs. owing a 3570k
In this usage scenario the computer is heavily used for tasks like folding, gaming or video editing

What is this pile of copy/pasted shit?Principle - Thursday, November 29, 2012 - link
Why is it that every review I see, no one uses the RAM that the CPU memory controller is rated for? Or in overclocking, did you see what a RAM overclock added?Just because your Intel chip may not perform any better with 1333, 1600, or 1866, doesnt mean you dont run your AMD chip with the 1866 its rated for. I see this all over the review sites. You dont have to use the same RAM in both systems for a comparison of CPU performance. RAM choice is designed into the CPU, and has an affect.

Nice job AMD. I guess some of these benchmarks are skewed because windows 8 is superior to windows 7 because it uses the modules better, but still.. the $166 8350 outperforms in some cases or comes close to the performance of a $200 i5-3570k.This is great news for AMD. Keep up the good work!

I find it funny all the Intel lovers are hating on so called AMD "fanboys."Isnt defending Intel and hating on AMD in turn make you all Intel "Fanboys."?
...Intel has not served me well I havent used one since my ol P4... I gladly claim the title of AMD "Fanboy.".
I have this CPU, Its pretty Epic.
