So the system memory is already slower than the memory on the GPU card? I suppose next you’ll also say the GPU memory is designed to be accessed in a much more “parallel fat pipe” way that can shove gobs of data across the bus all at once vs the CPU which doesn’t have that requirement? I mean the whole idea is “single instruction multiple data” and GPU takes that to the extreme… so yeah I guess the data pipeline has to be ultra-wide to shove shit across all the little cores as quickly as possible.
