NVMe protocol introduced namespaces. Is it not the feature perfect for users to decide themselves, how to create 2 virtual SSDs with TLC and pseudo-SLC-mode, choosing how much space to sacrifice for pSLC?

There is a rather cheap mainboard ASUS K14PA-U12 for 9004 EPYCs [1]. Strange, but it is missing support for 9005 Turin. How can this be (except of 400W+ models)? What do you think, could there be some true hardware issue making it impossibl

I'd have rather a question why we had single (or already dual) core CPUs with dual-channel memory controller and now we have 16-core CPUs but still with only dual-channel RAM.

Isn't it the small embedded support CPU core within the CPU I/O die that controls voltages and frequencies? Sure it depends of what is configured in BIOS.

BTW, if we copy data between some device and RAM efficiently using DMA without spending CPU cycles, why we can't use DMA to copy RAM-to-RAM?
