>The reason you would care about GPU rendering of the UI is mainly for battery life. It depends on the power draw of the CPU, which for the M1 family is unusually low. For instance, in today's Mac Studio review, Ars tested the power draw for various systems running a Handbrake encode with the CPUs running wide open. The plain M1 system was drawing 27 watts. The M1 Max was drawing 47 watts. The M1 Ultra was drawing 87 watts. The PC desktop running Alder Lake unlocked was drawing 300 watts. >Both the power-unlimited Core i9-12900 and the M1 Ultra performed roughly the same in our Handbrake video-encoding test, and the i9 did even better than the M1 Ultra in a handful of our CPU benchmarks. But measured at the wall, the Core i9 PC was drawing roughly 300 W of power the entire time the encoding task was running compared to the mid-80s for the M1 Ultra. https://arstechnica.com/gadgets/2022/03/mac-studio-review-a-nearly-perfect-workhorse-mac/ https://arstechnica.com/gadgets/2022/03/mac-studio-review-a-...
