Looking at sustained single-core bandwidth for a kernel composed of 100% reads, the trends for a large set of high-end AMD and Intel processors are shown in the figure below: So from 2010 to 2023, the sustainable single-core bandwidth increased by about 2x on Intel processors and about 5x on AMD processors.

My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

By Werner Vogels on 12 July 2010 05:00 PM. In particular this has been true for applications based on algorithms - often MPI-based - that depend on frequent low-latency communication and/or require significant cross sectional bandwidth.

Hardware Past As Performance Prologue. Regardless, the overall story for hardware progress remains grim, particularly when we recall how long device replacement cycles are: Tap for a larger version. Sadly, data on latency is harder to get, even from Google's perch, so progress there is somewhat more difficult to judge.
