I just want to add on that sentence as that's not what I wrote in the piece: I don't think the memory subsystem is to blame.

It's significantly stronger than ICL and showcases *much* better DRAM latency and significant single core bandwidth uplift. 429.mcf showcases great scaling well beyond clocks, showing that latency for example is not to blame. In my opinion it's a regression *because* of the reworked cache, as essentially the L3 is now 20% slower per clock versus ICL.
