I wish they would just jump DDR5 and go straight to DDR6, the PS5 and Xbox series X will have 16GB DDR6 as standard so I think anything new that comes to PC now should be at least that.
The consoles are using GDDR6 not DDR6. Different beast totally…
Consoles use GDDR as system memory?
Myself I've only just moved from DDR3 to DDR4. Please don't make my new system obsolete as soon as I've built it….
I will take new hardware ( CPU - MOBO ) with 8 X 64 GB DDR8400 RAM.
Only problem is no one will buy it for me
My current CPU will not push 64Gb of RAM at 3600 MHZ, it will only do that with 32GB, so i have to make do with just shy of 3500 MHZ cuz i cant be bothered with tweaking it more.

Next gen yes. Quickest memory/most bandwidth and available now

Only 16 gig of 3000 here. Ryzen 7 2700 won't go higher without odd cold boot issue

I suppose they really don't have to care about general system performance that much…. there will be more than enough grunt there to overcome the inefficiencies brought in by using suboptimal memory for the occasional application.
Is ECC part of the DDR5 spec? I can't find any details about that elsewhere, so perhaps it's a value-add just for this manufacturer.
I once read an estimate of a cosmic ray flipping a bit at once per decade per 8GB. So in a 64GB workstation that's every year or two, and in servers that'd be every few months :(

There will be millions sold they will get a great price. It's about cost V performance on a console anyhoo

I *think* ECC is part of the spec….
Big difference is these console's have the ram very close to the CPU so less issue with long length track traces in interference and timing differences. Classic PC memory is more further away and more likely the reason it lags behind a couple of sped generations from its GDDR equivalent.

On-die ECC is part of the spec.

While that does make a difference I'm not sure an extra few inches would be noticeable from an overall system perspective, we're talking about a signal travelling at something like 50 to 90 odd percent of the speed of light, IIRC that's roughly 12 inches per nanosecond so at most you'd be talking about 1ns.
It not so the travel speed but interference(Signal Quality), track trace resistance, capacitance rf interference from adjacent tracks isolation and grounding all effect the signal quality further away the greater the issues.
So there's potential for a ryzen 5, DDR5 and PCIe 5 combo in 2021?
