Computer architects use the term 'memory wall' to refer to this latency problem. CPU microarchitectures are constantly improved to improve IPC, Die technology helps increase CPU frequency, but memory access latency is not keeping up with the CPU improvements.
- NovemberWhiskey 4y agoRight - I think, at this point, that L1 cache latency is worse than main-memory latency on a 'per CPU clock' basis than it was in the late 1990s!
- rbanffy 4y agoMakes sense for a larger cache to take longer to decode an address.
