For the most part, the M1 iPad Pro features a desktop-class chip, which is incredible given how thin and light it is. This can mean that for intensive CPU and GPU tests, the M1 will crush anything thrown in its direction, but at the same, consume more power than traditional smartphone chipsets. Well, that is exactly the case, according to a series of tests done.

Golden Retriever on Twitter has published some power consumption tests of the M1 iPad Pro, and given that the same chip found in the redesigned iMac also made its way to Apple’s flagship tablet, you can expect it to consume a fair amount of power. According to the tweet, playing Divinity: Original Sin II allows the M1 chip to really flex its muscles, so the combined load on the 8-core CPU and 8-core GPU mounts to 19.9 watts of power consumption.
