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.

I'm sorry, but I can't take seriously anything where the writer uses "Windoze". Any such text is obviously written by a heavily biased individual and therefore any "analysis" in it is flawed.Finally - Tuesday, October 23, 2012 - link

X2 this guy is one of those "Linux Zealots" Pretty sad that there are still people out there that feel that way.andrewaggb - Tuesday, October 23, 2012 - link
It would be interesting to see some linux benchmarks considering this chip's only future may be running servers or bargain machines.Some linux webserver and sql database benchmarks would be interesting. I didn't see any desktop use case for this processor at all. In every benchmarked case I'd rather have an intel chip. Even when Intel lost it wasn't by much. And the conclusion basically said the same thing, if you are 100% sure you are running heavily threaded code all the time, then this MIGHT be the chip for you if you don't mind a bigger power bill. That's just not great.
But as for the windows remark, windows is fine. Linux has some strong points, particularly with servers, and it's kernel->user mode transitions, but everything is a trade off. I use linux for many of my servers and have for years, but I mostly agree with this http://linuxfonts.narod.ru/why.linux.is.not.ready.... as to the problems with linux. If you've genuinely used linux alot, you'll know most of these things are true to one degree or another. Basically once you get X audio and video involved, it's not awesome and you'll appreciate windows more :-)

If you prefer to analyze things scientifically and think independently you would NOT use your computer primarily or exsclusively for gaming, you are a one-dimensional human being IIt is a multi-faceted tool that can do work , organize a revolution, spread joy through its communications ability. Help the oppressed get together to fight their expoliters It can be entertaining as well. Practicing being a paid mercenary like the Seals does not intrigue me, it repulses me.There is nothing this cpu can't do either better . as well, or almost as well asan Interl chip in its price class. Single-threaded apps are dying out. More and more games are being programmed to take advantage of multi cores and AMDs' superiority there is only going to grow. Dis it all you like it show your brain is not eoperating at a high efficiency. it is irrational just liek those Iphone nuts who stand on line for aproduct that is being bought as a status symbol rather than as a superior tool (which it is not).

Thank you so much mr revolution. By the way obnoxious idiot, you have NO IDEA how the person you responded to uses his or her computer(s) !We get it, you're a dyed in the wool amd freak. Now explain how the 2500K at 4500mhz on stock everything doesn't smoke the spanking lies out of you?
LOL - see you at the FEMA CAMP, i'll be on the other side of the barbed wire, mr revolutionary.

Let me just say. Shut up.als2we - Friday, August 16, 2013 - link
Just look at the facts , more performance for your $$ http://www.cpubenchmark.net/cpu.php?cpu=AMD+FX-835...AMD has it there we need it there , if amd goes away Intel can charge what ever they want ..........

It doesn't matter if something is multithreaded or not. If it doesn't use more than 4 threads Intel's Single threaded advantage still holds.Only until you fully saturate the 8threads does the AMD, maybe, pull ever so slightly ahead. Even sometimes there it falls way behind.
If the amount of threads your software is asking is equal to the amount of cores your Core I7,5,3 has the Intel is spanking AMD. Only if the amount of cores DOUBLES intel's is the AMD maybe winning alittle bit.

I'm sorry, this is a bit off-topic to the processors (although I can't say I'm partial to either, I'll be using an AMD because it works in the motherboard I want and performs well with all the other parts I want, but I have used my friend's i5 build and it runs very nicely) but how do you say that Linux is only for servers and bargain builds? Besides the fact that I have seen $600 builds that blow away multiple thousand dollar builds, Linux has become an extremely advanced OS in the last few years. The desktop environments available are all more intuitive than either Windows or Mac, given that they can be customized to the user's preferences down to where they interact directly with the kernel. Not to mention they offer a vast array of features that Windows and Mac don't, as well as using far less resources. I have Linux operating systems that will idle around 1.2% CPU usage. Windows 7 idles around 5%-6%. It manages network connections more efficiently, utilizes the resources it does use much more effectively, and in general just gives a much more immersive and intuitive user experience if you know what you're doing. I would really like to see more support for Linux, because if software and firmware that is available for Windows was available for Linux without the use of WINE, I would use Linux exclusively because it would be so much more efficient, and at this point it has become so streamlined and beautiful that most people who have seen me using it and are Windows users say they would switch because of it's ease of use and visual appeal if only all the software they use on Windows was available. Oh and putting servers and bargain builds in the same group really wasn't well thought out... Most servers have high end components to be able to handle large amounts of traffic and heavy loads on resources.
