Benchmarks – Multi Core
The benchmarks were run on the QX9650 and E6850 with multi core enabled, this means though that benchmarks which benefit from the extra cores on the QX9650 you will see a large difference, but not all benchmarks support multiple cores, and thus the advantage of the QX is lost.
First up we compare the raw CPU performance with PiFast,SuperPi and Wprime:
PiFast and SuperPi take no advantage of the extra cores on the QX9650, but the extra L2 cache does pay off, SuperPi 1M improves by ~12%, 32M sees less effect, only ~3%; PiFast even less at only ~1%. Wprime does support multi core, the quick calculation of Wprime 32M is ~53% faster on the Quad Core QX9650, the longer Wprime 1024M also improves by the same amount.
Moving on the synthetic benchmarks of Sisoft Sandra 2008:
The multimedia tests more than double, the Multimedia Int improves by 135%! The Arithmetic tests are even more impressive, increasing up to 147%.
The Cinebench includes single core as well as multi core results, you can see that the QX9650 already has a small lead over the E6850 when both are using only 1 core, about ~10% better. The benchmark does not scale perfectly to the maximum amount of cores, otherwise the E6850 should be at 1000 and the QX9650 at 2000.
The x264 encoding test next:
The more cores the merrier, close to 100% increase at the 1st pass, and up to 123% faster on the 2nd pass.
