More cache would be better for a number of workloads, sure, but it wouldn't work miracles. There's pretty much nothing that could be done to make Sapphire Rapids competitive with Genoa. Just a long, long wait to Granite or Diamond Rapids...A full unrestrained Raptor Cove vs Genoa Would be an amazing match. 64C/128T With 192 MiB L3. But instead the best Sapphire Rapids will bring 60C/120T with 112 MiB..
Chips and Cheese made Cache System Simulation and Alder Lake gains IPC just by encreasing the shared L3 from 30 MiB to 36 MiB, and that happens to be Raptor Lake.
Processor speed has rapidly outpaced advances in DRAM technology, so caching strategy is a huge part of CPU performance today. A couple of articles ago, we saw Intel’s decisions with Golden C…chipsandcheese.com
