News Intel's Arrow Lake official memory speeds are unchanged with standard memory sticks — pricier CUDIMM memory needed for faster base spec

Intel Arrow Lake chips require CUDIMM sticks if you want to enjoy DDR5-6400 speeds without XMP.

I need some more information on this, but maybe I'll have to wait for the benchmarks. When building my last PC I caught a sale that made buying PC 3600 only a bit more expensive than 3200. But I learn later that it made almost zero difference on an Intel system. (I'm a bit of a perfectionist so it's annoyed me ever since even though we're talking about $20 or so.)

Any idea on how is this going to work out? Or do we have to just wait and see? I will be building a new PC at the beginning of the year, but I may snag an item or two before then if it's on sale.

Intel has mentioned to press DDR5-8000 is what they expect most ARL CPUs to be able to run at. This would be when using CUDIMMs as opposed to UDIMMs most likely. With ADL/RPL this was DDR5-7200 (easy on RPL, sometimes not on ADL) and while you could go higher diminishing returns meant not much to gain versus the massive cost increase.

It's a safe bet that 8000 will have some sort of performance improvement (as long as latency is equivalent), but without reviewers doing memory scaling tests it's impossible to say how much. That's the sort of thing which simply has to be a wait and see. CUDIMM availability does not seem like it will match the launch of ARL, but hopefully some will arrive before the end of the year.

If you were thinking of getting memory as one of your earlier purchases I'd suggest not unless the real world performance and stability has been tested. As it is if CUDIMMs do turn out to be the way to go chances of them having sale prices is likely very low.

XMP memory makes little to no difference unless you are running something that is really bandwidth starved, like unzipping or something like that.
