Sandra SiSoftware 2012 Benchmark Results!

Round 14 : Sandra SiSoftware 2012 Benchmark Results!  

CPU 1: Intel i7 2600k @ 4.3 Ghz
CPU 2: Intel i7 2600k @ 4.6 Ghz, DDR3 @ 2133 CL11
CPU 3: AMD FX 8150 @ 4.8 Ghz, Gskill DDR3 @ 2183 CL10

Here we see that the FX Patch brings a decent boost in performance, averaging +5.17% across all 12 tests. The largest performance increase comes in the .NET Arithmetic - Dhrystone test, where we see a +24.6% difference. This is the most significant increase in performance I have yet to see for the FX patch. 

Comparing my AMD FX 8150 @ 4.8 Ghz to an intel 2600k @ 4.6 Ghz for 10 of the 12 tests, and a 2600k @ 4.3 Ghz for 2 of the 12 tests, we see an average performance difference of -0.07% , implying that AMD is still not so behind in this notoriously Intel favoured benchmark. The reason that two of the tests were not carried out @ 4.6 Ghz in the .NET Arithmetic scores , but instead @ 4.3 Ghz , is because scores @ 4.6 Ghz were not included in the internal comparison benchmarks listed. Of course this will play into the averaged difference, so I suspect that the 2600k @ 4.8 Ghz should beat the FX 8150 @ 4.8 Ghz by an average of 5% give or take. I might re visit this later on with my own testing to confirm this. 

We can really see that intel and AMD have different strengths and weaknesses across the 12 tests in this benchmark. 

Also notice how memory scores for G.Skill Ram @ 2183 Mhz CL10 only trail the intel's score with Ram @ 2133 Mhz CL11 by -4.8%/-4.6%.
