SK hynix says DDR5 mass production will begin this year

First DDR5 DIMMs will be about 1.5x faster and offer over a third more bandwidth than DDR4.

The consoles are using GDDR6 not DDR6. Different beast totally...

Ok thanks for the correction, only thing is the consoles use it for the whole system not just graphics.
So i'm guessing the PC accesses the CPU mostly so DDR5 is lower bandwidth tighter timing more efficient for CPU access whereas GDDR6 is high bandwidth loose timing better for GPU i guess.
Just found this explanation it was quite helpful.

Re: SK hynix says DDR5 mass production will begin this year
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....
Re: SK hynix says DDR5 mass production will begin this year
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.
Re: SK hynix says DDR5 mass production will begin this year
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....
Re: SK hynix says DDR5 mass production will begin this year
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.
Re: SK hynix says DDR5 mass production will begin this year
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.
