Ramspeed is not going to matter given rumors that RDNA4 is aiming for small-die low-mid segment. If AMD even went for that option (small monolithic dies) in the first place, they clearly are aiming for value, lower BOM, can price it competitive & still profit.
Been rumoured for a while now that RDNA4 will be for entry-level/midrange, with no high-end/enthusiast cards, so this makes sense.
18Gbps will be readily available, also what PS5 Pro is rumoured to use.
