Half that - 4 MB per core so the 64 core CPU has 256 MB (dual socket is where the 512 number comes from but that's 128 cores and NUMA).

It's also not fully accessible, each core can only directly access the 16 MB in its group of 4. Everything else is the same as a cross cache read.

Ah, yeah. Mixed up their CCD and CCX terms. The 690MP was dual socket though, so still a somewhat valid comparison.
