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

Redis's microsecond latency has made it a de facto choice for caching. Four years ago, as part of our AWS fast data journey, we introduced Amazon ElastiCache for Redis , a fully managed, in-memory data store that operates at microsecond latency. Whether it is gaming, adtech, travel, or retail—speed wins, it's simple.

A few years ago I spent a few weeks doing some memory investigations on live game servers. I found a series of bugs that were causing memory usage to be triple what it needed to be and I fixed those: I found map ID mismatches which meant that a new copy of ~20 MB of data was loaded for every game instead of being reused I found an unused (!)

We're burning our inheritance and polluting the ecosystem on shockingly thin, perniciously marketed claims of "speed" and "agility" and "better UX" that have not panned out at all.

In recent years GPU development that was originally funded by the gaming market (and ended up being used as a supercomputer accelerator) has been dominated by use in the AI/ML accelerator market. Many HPC workloads synchronize work on a barrier, and work much better if there’s a consistently narrow latency distribution without a long tail.

This is a complex topic, but to borrow from a recent post , web performance expands access to information and services by reducing latency and variance across interactions in a session, with a particular focus on the tail of the distribution (P75+). Consistent performance matters just as much as low average latency.
