From past experience with the 7900X3D I use to have, the difference was pretty moot. 7800/8000 c36/38 was generally worse latency, 5-8% bandwidth increase and incredibly difficult to stabilize with the exception of using the Tachyon/Gene. Meanwhile 6400 c32 was much easier to run/stabilize (as well as getting others OCN’ers stabilized here), with better latency, and slightly less bandwidth at much more sane voltages.
Remains to be seen if DDR5 8000 is worth it, when something along the lines of 6400 with tight timings provides similar results. This is especially true when only very specific workloads or synthetics can take advantage of this; potentially useless for 90%+ of users.
Oh yeah stabilizing it on the 2DPC X670's is a nightmare and there are very few 1DPC boards out there. But apparently that's what they are aiming for with X870, not sure how. I do hear there's a Tachyon being released and if it's not vaporware i'll try to snag one.
I was thinking more along the lines of 8000 c34 with tuned subtimings should be possible and then see how it fares vs tuned 6400.
