![]() We saw a 1.5ns memory penalty from Coffee/Comet to Rocket Lake, and should see slightly more on Alder, but we'll have to wait and see, regardless we should still be able to hit very close to 40ns, meanwhile on DDR5 you'd be lucky to get even remotely close to 50ns, that'd take new ICs that can do 8000 MT/s C元0, fastest DDR5 overclock I've seen is 8000 MT/s at CL50, we're maybe a year away from decent DDR5 latency. Coffee/Comet to Rocket Lake we saw 20% IPC improvement from 25% larger cores, double L2 cache and more, now we're seeing the same plus a little more from more than double L2 cache and close to double 元 cache. Zen3 gains a few % over Rocket Lake in some titles (mainly from increased core count on 5900X and 5950X) and in others the roles are reversed, Rocket Lake on top by a few %.Īlder Lake with Rocket Lake memory is where the magic will happen, looking at roughly ~20-25% higher performance. So they even out, that's really it, not more complicated than that. ![]() Click to expand.Rocket Lake and Zen3 trade blows, Rocket Lake has faster memory (~12ns lower) but Zen3 has twice the 元 cache, 2 to 4MB per core.
