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

x264 HD 5.0.1 Benchmark
We migrated to the latest verison of the x264 HD benchmark which features a much newer version of x264 and a much heavier workload. The focus here is on quality rather than speed, thus the benchmark uses a 2-pass encode and reports the average frame rate in each pass.
The latest version of the x264 HD test does extremely well on Vishera. With the exception of the FX-6300, AMD is able to come away with a win at all of its price points. The FX-8350 even outperforms the Core i7 3770K.
Visual Studio 2012 - Multithreaded Compile Performance
Our compile test is back and better than ever. With a much larger and faster SSD (Samsung SSD 830, 512GB), we're able to get more consistent compile times between runs. We're now using Visual Studio 2012 to compile Mozilla's Firefox project. The compile is multithreaded however there are periods of serial operation where performance is bound by the speed of a single core. The end result is a benchmark that stresses both single and multithreaded performance. Compile times are reported in minutes elapsed.
It's all or nothing with Vishera. Mixed workloads that stress both single and multithreaded performance don't turn out as well on AMD's platform. With the FX-8350 AMD is able to sneak up on Sandy Bridge, but the competitive Ivy Bridge parts simply pull ahead. If there ever was a reason to fix AMD's single threaded performance, you're looking at it.

Now what I'd like to see is how many of these benchmarks are compiled with intel compiler. In case you don't know yet, Intel Compiler disables a lot of optimizations if you are not running a Genuine Intel CPU, even if your CPU supports required features and would benefit from these optimizations. In other words, anything compiled with intel compiler will run slower on AMD cpus just because of Intel compiler.Now you can argue that this is a reflection of real performance on Windows, as in Windows quite a few of DLLs are compiled with Intel Compiler as well.
What I'd like to see is some more benchmarks for Linux operating system and/or professional software. Things like data base servers (including something non-Microsoft, like PostgreSQL or MySQL), java application servers, GCC compiler benchmarks, apache/PHP server, virtualization, python/perl/ruby, LibreOffice/OpenOffice productivity.
Now, back to Vishera. This looks like a nice CPU. I haven't been CPU bound in my work for a while now, so performance wise this would be sufficient for my needs. What I'd like to see however is lower power consumption. Unfortunatelly I don't see that coming until Global Foundries minimizes their process...

So amd has abandoned gamers on the cpu side.Good to know.

"As I mentioned earlier however, this particular test runs quicker on Vishera however the test would have to be much longer in order to really give AMD the overall efficiency advantage. "If you think about it, efficiency is unrelated to length of test.

He was talking about electrical usage vs work done, hence with amd's higher per second use of electricity, it must complete the test MUCH faster than Intel in order to win that.It completed faster, but not fast enough to use less power.
This lesson is over for amd.

In price per performance. A 125w part beating a 67w (Not sure about that figure) will cause Intel to keep the same TDW for 2014 and just have a 35-40% performance increase. I can only hope.CeriseCogburn - Tuesday, October 30, 2012 - link
If you're used to running or servicing Intel cpu's then you pick up the LEAD WEIGHT that is the modern AMD cpu, all that HEAT SINKING comes to mind.I mean they are just honkers. You pick it up and it's like what the heck !?

I wish Anandtech would include some form of value scatter graphs like Techreport does in its reviews. The graphs do not have to be an exact imitation of what Techreport does, and the benchmark(s) used to determine the 'overall performance' can be different. Perhas we could even get performance per watt per dollar graphs.Graphs like these make the whole exercise of comparing competing products so much more relevant to users, because most of us will buy the most performant processor per dollar.
As example:
http://techreport.com/r.x/amd-fx-8350/value-scatte...
http://techreport.com/r.x/amd-fx-8350/gaming-scatt...
This is, of course, considering the result without any attention to performance/watt. If you include power consumption in the calculations at all, Intel is an easy choice.
Difficult to see how AMD will cope with Haswell, even if they get another 15% boost next year. The gap in performance / watt only seems to be diverging, Intel taking a commanding lead.
