  Might be that AMD wants most gamers on these so they can sell their discrete GPU wares to the AI folks at double the revenue. All the games market has been chasing graphically is diminishing returns in terms of pumping rasterized polygons. 4k gaming is kind of stupid. Now the real time raytracing they are starting to do is interesting, but I noticed that has faded from the headlines as NVidia's stock exploded due to AI coprocessors.

  I do not really expect that, but it's possible to have higher-performance iGPUs than PCs have now; the bandwidth of two memory channels is a big constraint here. Apple's M3 Pro and Max appear to use 3 to 8(!) channels (and of course a lot of die area) to achieve good GPU performance. More channels may not even be physically possible in AM5. And economically any big change to build a super-iGPU has to compete with just not taping a bigger APU out and letting folks who want lots of oomph go discrete. The other thing that can maybe help is cache. AMD uses cache dies in their datacenter APUs (very unlike laptop APUs) and of course their dGPUs. Way back, Intel also made a product with eDRAM to boost effective memory bandwidth (Crystalwell). For an integrated chip, that could also act as an "L4" for the CPU and help with its bandwidth needs, though the impact there will be lower than for the GPU.
