Futuremark 3DMark05 build 120

There are benefits from the 32 PCI Express lanes servicing a multi-GPU graphics subsystem, but they show up only at very resource-consuming antialiasing levels when the amount of transferred data is so large that 16 lanes just cannot cope with it.

There’s almost no advantage visible in the second test because it renders a smaller scene than the first test, so the load on the graphics memory subsystem and the graphics bus is much lower.

The third 3DMark05 test renders a larger scene than the first one, but the new chipset from Nvidia doesn’t offer a big performance gain here because it is the number and efficiency of pixel processors that determine the speed in this test. Anyway, the nForce4 SLI X16 platform looks a little better in the 8x and 16x SLI AA modes.
