Spec wise this looks pretty much exactly what we are (likely) getting in the amd version.
The r7 7840hs(and probably also the u) has 8 zen4 cores and 12 rdna3 gpu cores and around 24mb of cache (if you add l3 and l2).
It’s interesting to see how bottlenecked the 12CU variant is.
By the ram or what do you mean?
Usually it’s memory throughput limiting these iGPUs. 3x the graphics cores for not nearly as great an uplift in performance.
