PCI Express And CrossFire Scaling: Is P55 Good Enough?

PCIe Scaling Results: Far Cry 2 And H.A.W.X.

Starting with Far Cry 2, most readers will probably notice that EVGA’s P55 SLI beats its X58 SLI in x16 mode. That’s not a benefit of P55 technology, but is instead a testament to how far EVGA has come as a motherboard manufacturer since the release of the earlier product. Both motherboards were chosen for their excellent layout, but our hopes that a BIOS update would correct the X58 SLI’s minor performance deficit have officially been dashed.

Far Cry 2 puts an exclamation mark on the P55’s poor x4 performance, but like previous benchmarks, it shows only a minor performance loss when switching from x16 to x8 transfer mode.

Unlike Far Cry 2, the P55’s x4 slot disadvantage appears to be slightly less pronounced in H.A.W.X. when AA is enabled.
