I have read about the newest AMD Ryzen CPU's and their impressive performance. But - They have only two memory channels which I find a bit peculiar. Is the total processing power/throughput not also depending on the number of memory channels? The Intel 775's had two. The 1366's had three, the 2011's four, So my question is if selecting a top performing CPU should besides clock speed and the amount of cache also be made upon the number of available memory channels. And furter, if looking for a CPU also should include support chips (bridges) that can handle registered DRAMs. Comments invited.
