What’s up all. I am waiting to see AMD and Intel offerings. Wanted to see what others might have done in my situation. I previously ran 13900ks with 4090 and 48GB of RAM. I use programs such as After Effects, Photoshop, Davinci Resolve, AI rendering programs but also gaming.
I want to achieve the same performance I’m used to but with more ram (128-192GB) but also keeping the cost down as much as possible.
I considered the 7960x and WX and I’m wondering what trade offs there are with trying to still get fast ram and more of it. I know on mainstream motherboards you can’t go over 48 for example without losing the speed. I’m also curious about the performance of those threadripper parts. Or… Should I just get the AMD or Intel part that’s about to launch.
I don’t know that you’ll find good memory scaling data for Storm Peak but Granite Ridge with 200-400 MT/s less capability should be close. 7960X and 9900X are both 6 cores/channel versus 3 cores/channel with a 7965X. From the OP it’s unclear how bandwidth or latency bound the workloads are so adding channels may or may not provide what you’re looking for. Particularly for gaming look also at the vcache (X3D) parts.
It’s not uncommon cost-workload analysis favors two (or more) desktops versus one workstation. In your case that sounds like maybe a dual UDIMM and a quad UDIMM build. For the quad I’d look at M- or A-die at lower speeds and tighter timings for easier thermals, particularly if you want tREFI > 3.9 μs, and the RDIMMs I’m seeing top out at DDR5-7600 anyways. (Inner DIMMs in quads see something like quadruple the thermal density of duals on a quad socket board and are harder to get airflow to.)
Insufficient data on Alder Lake as yet, wait and see. If it’s like Raptor the headline DDR5-6400 support’ll apply to dual DIMM on boards with two DIMM sockets rather than the usual four.
I’m unfamiliar with this aspect of Raptor’s scaling but with Zen 4 and Zen 5 there’s little to no penalty to like 2x48 dual rank DDR5-6000 versus 2x24 single rank DDR5-8000ish. What’s reported for quad DIMM on AM5 seems like it might often be B-die and XMP/EXPO limited with more recent AGESAs but it’s been hard to tell.
