You were wrong about the memory latency¹ increasing, but the memory latency² has increased (substantially) for most systems, while the memory latency³ has indeed decreased. In general, the memory latency¹ has not improved much. Of course, the memory latency⁴ has greatly increased, due to the clock frequency being increased so much to enable the higher bandwidth, while the memory latency¹ stayed mostly the same. [1] as in: access latency of the DRAM [2] as in: how long does a CPU memory read which is _not_ cached take [3] as in: how long does a CPU memory read on average take [4] as in: CL |
