Benchmark Results: Synthetic

System Builder Marathon, Sept. 2010: $2000 Performance PC

Anxious to gauge the “raw power” combination of a 4 GHz six-core CPU and two GeForce GTX 480s, we jumped straight to the synthetic tests. The game and program tests you'll find on the following pages will show how these results affect real-world performance.

Though the Phenom II X6 1055T’s low 2.8 GHz stock speed places a significant barrier to 3D performance, pushing it to 4.0 GHz at least partially uncaps the GeForce GTX 480 graphics cards. The result is a big 3DMark win for this month’s overclocked PC.

PCMark doesn’t like the Nvidia chipset’s SATA controller and doesn’t care about the processor's extra cores, slapping down the new system even when overclocked.

Sandra Arithmetic appears to prefer Intel’s Core architecture taken from our June system, while its Multimedia test gets a big boost from this month’s AMD six-core chip.

The triple-channel memory subsystem on our June system beats this month’s dual-channel configuration. Because the performance difference is far greater than triple-channel’s 50% theoretical advantage, it appears that the former system’s Intel processor is also better at accessing available bandwidth. Both systems ran stock speed tests at DDR3-1333 CAS 9.
