![]() ![]() ![]() So the primary goal here is to compare two-way SLI Titan performance on PCIe 2 versus PCIe 3.Īt 2560x1440 there’s very little change. So with that in mind we’re going to finally publish that data, since there’s clearly more interest in the matter than I initially expected.Īs a heads up this data is a bit stale it was taken back in April with NVIDIA’s 314.22 drivers. However in the last couple of weeks I’ve received several requests for two-way SLI Titan/780 PCIe performance benchmarks, which we did happen to collect while looking into tri-SLI and merely never published. PCIe 2 comparison for tri-SLI Titans, and as a result the subject never reached print. The third x16 slot (electrically x8) won’t operate beyond PCIe 2 speeds even after forcing it in NVIDIA’s drivers, which is unfortunately a bit of a double whammy since it’s the slot that’s already lacking in bandwidth. IVB/Haswell is of course limited to 16 PCIe 3 lanes, whereas if PCIe 3 is enabled SNB-E systems have more than twice that with a combined total of 40 lanes, giving SNB-E a large bandwidth advantage.Īs it turned out, the Intel DX79SR used in the Genesis supported PCIe 3, but only on the 2 full-fledged x16 slots. ![]() As a result there was some interest in whether PCIe 3 would improve performance at all compared to PCIe 2, due to the high amount of PCIe bus traffic generated by three GTX Titan cards working together. Because we tested the system with its default out of the box settings, the system was configured by default to only use PCIe 2 since NVIDIA does not officially support PCIe 3 on SNB-E based systems. Aborting for debugging purposes.If i run paraview just on its own it seems to work fine.Back when I had Origin’s tri-Titan equipped Genesis in house, I received a few requests for benchmarks with PCIe 3 enabled. ![]() VtkSISourceProxy (0x31f8630): Failed to create vtkAdiosPixieReader.
