AMD's latest Ryzen processors expected to support CUDIMMs, just like Intel's Arrow Lake-S.

Meh without increased IF speeds whats the point?

 

[edzieba]

CUDIMMs fall back to regular DDR behaviour (external clocking) by design. That they work in regular DDR slots is the intended outcome.

Yeah, that's what I was thinking.
I was under the impression AM5 had no benefit over DDR5-6000, so you are better off going for tighter timings than speed.

I'm still mostly curious about the bypass mode implementation because while I haven't got into the specifications my understanding from reporting on CUDIMMs is that it's intended to be for slower speeds. There's a slide wccftech has showing that they only work in bypass mode which negates the advantage they bring.

As for AMD memory scaling TPU did a piece and it seems to largely be a wash right now, but low latency 7200 shows some potential:

DDR5 Memory Performance Scaling with AMD Zen 5

Our AMD Zen 5 Memory Scaling Review examines six different DDR5 memory speeds, including DDR5-8000, DDR5-6400 1:1, DDR5-6400 CL28 and others. We looked into how these speeds impact performance in gaming at four resolutions and a wide range of application workloads.
