Well, this is much more interesting... With the smaller memory carve out, Lemonade with Llama.cpp was enjoying much greater gains out of AMD PerfOpt.

Some very nice improvements for throughput and lower latency with AMD PerfOpt on Strix Point with the Radeon 890M integrated graphics. Linux 7.4 just got a whole lot more exciting.
