Buffering Disabled
WIthout buffering, prefetching is disabled which means that there is no real data streaming possible, even though accesses can stay
in page. This naturally reduces the overall bandwidth and consequently, the chipset and bus bottlenecks are no longer as limiting as
they were in the streaming application. Therefore, it is not too surprising that bandwidth gets the better of latencies, meaning that the
higher memory frequency shows slightly better results.
