ddr4 vs ddr5 for Workstation and gaming

[Lizned]

Hey,

ok, so as a video editor by trade, and gamer by night, I’m upgrading soon and was leaning towards the R9 7950x which, in the first place, would have limited me to only ddr5 ram. However, with the recent announcement of the intel 13th Gen, 13900k, and it being cheaper, having more cores, and being backwards compatible with ddr4 ram, I’m definitely leaning more towards team blue.

 

But that leaves me with a decision in terms of ram. I don’t know a whole lot about the ram differences other than ddr5 is just faster, so I want to ask, what is the difference between ddr4 and ddr5 in laymans terms, and working mostly with the Adobe CC, would it matter that much performance wise, if I were to save a buck and use the less expensive ddr4 memory? At first glance it doesn’t seem to me that it’s worth an extra $300 to $400. I’ll be getting 128gb, if that helps your response. Thanks!

I'd wait for reviews to see how they actually stack up before making a purchasing decision.

A worthwhile thing might be the built in ECC inside DDR5. Unlike Ryzen which has supported ECC since first gen, intel has never allowed ECC ram with their consumer cpus, so you can only use normal ddr4.

But normal DDR5, while not having full end to end from memory cell to cpu ECC, still has on-die ECC, so it protects you still infinitely more than DDR4 with no ECC.

 

I pointed it out as you said workstation. But being that it seems like you won't do some super mission critical stuff, ECC might not be worth it to you, as you can just re-render etc if you encounter an error.
