@mrvn: it is much more complex very fast. For example a different number of GPU-kernels can make a difference in result, if they are not somehow synchronized. This synchronization can become super complex (number of kernels is just one factor of many) for quite simple tasks.
That would be relevant for multiplayer. Different GPU from different vendors might not even get anywhere close to the same result because they round floats differently. (Do they? I know intel and amd cpus do. Anything that relies on the lowest bits of a float will desync.)

But I was talking about running the same game on the same hardware again. You have the same number of GPU-kernels then.
