Final 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.

    but at least priced decently. Reply

    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)

    also to add if you own an Bulldozer (or Vishera) type of cpu you should all ready have these patches installed

    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. Reply

    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. Reply

    Because performance = core count. Brilliant. Reply

    You know, you look at this crap amd chip in the review, and then it hits you... hard

    You 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.

    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.

    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.

    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)
