Intel's Lakefield also comes to mind, pretty underrated chip imo. The first x86 big/small heterogenous chip, using Intel's Foveros to stack memory, CPU, and platform chip into one package. It made for a very simple design that just needed power. LPDDR4X-4266 doesn't crazy fast but in 2020 it was pretty swift. https://www.anandtech.com/show/15877/intel-hybrid-cpu-lakefield-all-you-need-to-know/3 https://www.anandtech.com/show/15877/intel-hybrid-cpu-lakefi... Alas the 1+4 Skylake+atom were all pretty meh chips & Intel hasn't tried again. Conceptually I really.liked it, and it was doing great against the Qualcomm 8cx competitor for the tablets/2-in-1s it was in, but people wanted more.
