It would make zero difference, except, maybe, for the PCIe bandwidth test. Because all other tests were stressed interfaces that reside within the GPU silicon itself or between the GPU and the DRAM.
Even the numbers of PCIe bandwidth test might not change much, even it's trying to test medium size memory to memory block transfers.
