Didn’t Intel have a similar idea with Skylake? Those had very fast albeit smaller eDRAM die glued to the processor. It was dropped on subsequent generations.

It’s actually still surprisingly relevant in terms of performance [1], and I see it as a precursor to the gigantic caches we are seeing in the latest chips.

It worked pretty well but Intel clearly never liked the idea. They only offered it on a couple low-end models even before dropping it.

My impression was that this may have been designed at Apple’ behest; certainly they were the major user. Older than Skylake, btw; Haswell had it.
