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.
