Default Re: Return of AMD FX: My OC'd AMD FX 8150 / 6990 review

3DMark11 Performance / Extreme Performance

ROUND 2 : 3DMark11

Finally a benchmark that utilizes GPU! We will see here whether FX bottlenecks or not while overclocked to 4.8 Ghz. The score to really look at is GPU score (as this directly relates to fps of the rendered scenes), but because the total score also heavily relies on GPU score (especially in the Extreme Preset) it is also a good measure.


3DMark11 Performance Preset:

AMD FX 8150 @ 4.8 Ghz
6990 OC @ 990/1500 Mhz

Compared Results (with several 6990 OC's) :

As you can see the graphics score of my OC'd 6990 does not fall systematically behind intel rigs with similar GPU OC's. My GPU Score of 12046 is a clear winner over the rest of the rigs tested., however with combined and physics scores also put into consideration FX falls behind with a total score of only 10318.

The most noted comparison is that with the i5 2500k at 5.35 Ghz with a 6990 @ 1000/1420. Although it manages to squeeze out slightly higher combines/physics score, it still seems to bottleneck in GPU scores. The only intel cpu coming close to FX GPU score is the 3960x.

It should be noted that the OC on the 6990 does play a role in GPU score, so take these results with a grain of salt. a 930 Mhz OC is still 7% below a 990 Mhz OC, but nevertheless we can determine that FX does not heavily bottleneck when it is overclocked to 4.8 Ghz. What about Extreme Preset?

3DMark11 Extreme Preset:

AMD FX 8150 @ 4.8 Ghz
6990 OC1 @ 880/1250Mhz
6990 OC2 @ 990/1500 Mhz

- - - OC1 - - - 6990 @ 880/1250Mhz
