Here are some Geekbench 4 comparisons between the HP Elite x2 1012 G2 and the New Surface Pro, both on the same i5-7300U. They benchmark roughly the same with the Elite x2 having a slight edge overall. So if you were tied between those, you can take the CPU performance out of the equation, and focus on the other differences. https://browser.primatelabs.com/v4/cpu/compare/3093930?baseline=3091574 and https://browser.primatelabs.com/v4/cpu/compare/3093752?baseline=3019093 These aren't the best scores for an i5-7300U in their database, but the results are respectable: https://browser.primatelabs.com/v4/cpu/search?dir=desc&q=i5-7300u&sort=multicore_score Those Geekbench results should always be loeked at with a skeptical eye, since you never know the testing conditions and there is usually a big variation in test results for the same device configuration. But another thing that this tells us is, that just like Acer before with the Switch Alpha 12, Microsoft seems to have figured out fanless cooling of a U-class CPU. There is certainly still going to be some heavy throttling with extended CPU stress.
