Question DDR5 MB first AMD or Intel?

[Kedas]

AMD has the flexibility to do DDR4 and DDR5 at the same time with the same 8 core dies. (limited cost)
Intel has the money to just make extra dies. (after they figure out to use 10nm or not)

Did Haswell ever support DDR4?

Haswell-E did, though true that's a new chip entirely.

but for me, I would like them to keep the voltages high where possible (process) and start chasing some higher clocks!

I'm afraid that DDR5 will need active cooling regardless. BTW Hynix plans DDR5-8400 with just 1.1v so the clocks will be fine regardless (just think what 1.25v can do then). Also, there hasn't been a DDR generation that hasn't lowered voltages

That's what I'm talking about. If you look at DDR latency by generation, some of the best latency rated in ns still belongs to some old DDR systems from over a decade ago. I don't expect AMD to go that low due to IF, but the opportunities for lower latency are there.

Also Broadwell and Skylake. I have a 6700HQ laptop with DDR3. I'm not sure if the IMC in all Skylake derivatives still supports DDR 3 though. Certainly the platforms haven't been exposing support for a long time.
