Foveros and 3D stacking are a really cool technology. Packing so much logic into such a small form factor is awesome. Somewhat underwhelming, though, that there’s only a single sunny cove core. Now that Windows has ARM support, it would be much more interesting if Intel replaced the Atom cores with first party designed ARM cores then used the sunny cove/large x86 core as a sort of coprocessor to accelerate x86 programs without needing it to be emulated on ARM. Best of both worlds.
