AMD FX-8350 Vishera 8-Core CPU Review

Test System Configuration Notes: When configuring our test systems for this article, we first entered their respective system BIOSes and set each board to its "Optimized" or "High performance Defaults". We then saved the settings, re-entered the BIOS and set the memory speed to each platform's highest, officially supported frequency--1866MHz in the case of AMD's newest FX series processors.  The solid state drives in the test systems were then formatted, and Windows 7 Ultimate x64 was installed. When the Windows installation was complete, we fully updated the OS, and installed the drivers necessary for our components. Auto-Updating and Windows Defender were then disabled and we installed all of our benchmarking software, performed a disk clean-up, cleared any prefetch and temp data, and ran the tests.

Preliminary Testing with SiSoft SANDRA 2012
Synthetic Benchmarks

We began our testing with SiSoftware's SANDRA 2012, the System ANalyzer, Diagnostic and Reporting Assistant. We ran four of the built-in subsystem tests that partially comprise the SANDRA 2012 suite with Intel's new Core i7 "Ivy Bridge" processor (CPU Arithmetic, Multimedia, Memory Bandwidth, and Cache and Memory). All of the scores reported below were taken with the processor running at its default clock speed of 4GHz (4.2GHz Turbo) with 8GB of DDR3-1866 RAM running in dual-channel mode on the Asus CrossHair V Formula motherboard.


Processor Arithmetic
 AMD FX-8350

 

Processor Multimedia
 AMD FX-8350

Memory Bandwidth
 AMD FX-8350

Cache and Memory
 AMD FX-8350

SiSoft SANDRA didn't reveal any surprises with the AMD FX-8350. As expected, the FX-8350 proved to be faster than the previous-gen FX-8150 across the board, but it couldn't keep pace with the higher-end Intel Core i5 or Core i7 processors. According to SANDRA, the FX-8350 / 990FX combo put up just shy of 19GB/s in the memory bandwidth benchmark and the Cache and Memory test shows relatively high latency until the data set hits about the 512K mark, where the FX-8350 then becomes more competitive with other platforms.

results are weird. I5 doing just as well as the i7s in some cases. Are these software tests suitable?

Results are not weird at all. The tests are a combination of single and multi-threaded workloads, and we've got three families / generations of Intel processors represented. In single threaded workloads, the newer Ivy Bridge-based Core i5's are sometimes able to outperform older Sandy Bridge-based chips due to architectural enhancements and higher Turbo speeds. Also note that additional cores and support for HT won't benefit a test that's single or dual-threaded at most.

I just had to make this decision for a client who was having difficulties with her Phenom II 965 system which I recognized because we have the same issues on my system with the same processor and MB and frequent lock ups. This is a different architecture all together from CPU to board to memory bus I know but the price difference for an i7-3820 relative to the productivity it produces for her applications as a professional architect are to good to not go with them. This processor is also a couple weeks to late for the necessity we had at then, either way the price VS the performance makes it irrelevant either way.

Irrelevant?,......I don't think so.

When you consider that most of Intel's latest CPUs require you to buy a new motherboard to go with your shiny new chip, the AM3+ board's ability to run the latest FX processors gains a new clarity.

Even though I already have an FX-4170, I can just buy a FX-8350 CPU and install it and I'm upgraded. I might need a BIOS update, but that's no big deal. The performance isn't what my i7-2600K gets, but it's completely acceptable for my needs.

Marco, I have a question,............I've heard it said that Windows eight has optimizations built-in that take advantage of AMD Vishera's newer design. Is this true, or is it just so much BS?

Did you test this CPU with Win-8 to see if it performs better in Win-8 as opposed to Win-7? Are there any plans to do so?

@Realneil - Windows 8 does have updates to the scheduler that should increase performance and efficiency slightly with Bulldozer and Piledriver, but the I haven't done any official testing. Don't expect much of a boost though--a couple of percentage points here and there, tops.

Thanks for the answer Marco.

I may get one of these FX-8350 CPUs once the prices calm down a little.

Me too, the performance looks good enough for me, but Newegg has them listed for $30 over msrp. Maybe next month will be the time to buy.

That's why I'm waiting. I don't like the 'brand new' tax either.

Ok, so I am in the middle of deciding between this Amd fx 8350 processor and the Intel® Core™ i7 3970X Six-core 3.5GHz/4.0GHz Turbo 15MB L3 Cache w/ HyperThreading. I have been asking a lot of people for their opinion and really want to know, which processor will preform better? Can someone please tell me which processor has better performance? Thanks.

They both will perform well, but the Intel part is certainly faster.

You already know that you'll pay a hefty price premium for the extra performance though. The motherboard will be more expensive too.

The bottom line is that the AMD setup is plenty good enough for most uses, but the Uber Expensive Intel part that you're comparing it to is the performance king.
