I wasn’t suggesting probing caches is the main cost, I only wanted to describe that there is a long journey to DRAM in current architectures of which signal propagation is such a small part. You are totally right that…
Transmission time isn’t really the main issue, it’s more about the work required to get a memory request through the levels of the hierarchy to DRAM and back. Probing each level of cache, propagating through the miss…
