You need think of it as aggregate memory, not as per core memory to use if effectively. Are you aware of a chip with more than 64MB of on chip RAM?

The latest generations of IBM Power processors have >64MB L3 caches on chip. The Power 7+ has 80MB per chip, the 12 core Power 8 96MB, according to Wikipedia the Power 9 will have 120MB.

Good data! That puts e5 in good company with some big-iron heavies.

I realize comparing to Intel is unfair but I think the Skylake Iris Pro 580 has 128MB on chip RAM. https://en.wikipedia.org/wiki/Intel_HD_and_Iris_Graphics#Sky...

That's eDRAM though, and it's really on-module rather than on-chip. It's a separate die on the same module as the main SoC.

64 MB static RAM, no less. You've built a huge-ass static RAM chip and thrown in some local processing. (-:
