How come integrated graphics is in the CPU, rather than being part of the chipset? For an actual single-chip SoC, i suppose it has to be, but even my Ryzen 5 7600X has graphics. I would have thought resources on the CPU would be at a premium, so you'd put them all towards compute. Particularly since integrated graphics doesn't need to be that powerful.
Today's northbridge (aka: Memory controller) is on CPUs. GPUs need a powerful memory controller. And the most powerful memory controller between CPU and Southbridge/Chipset is the memory controller on the CPU itself.
More generally there isn't really a place for low performance integrated graphis any more and southbridge style chips are made with old old cheap processes that cripped with poor memory access would probably not run any modern desktop well.
A second option for the memory would be to put a small amount of local memory on the mobo along with the chipset, which again would be slow and still costly while losing the normal iGPU advantage of unified gpu & cpu memory access to th same data (UMA).
High end Apple M chips have it beat still I think.
edit: there's a new marketing claim from AMD that it beats M4 in some configuraton by 2.6x: https://www.amd.com/en/developer/resources/technical-article... .. but it's a small memory mode of M4 Pro, I wonder if there's independently benchmarked numbers of M4 Max vs the 395 out there.
