Hardware

GPUs have their own cooler to compenstate for pricing msrp. And AMD this generation offers much better pricing and performance (rander) with a 50 watts power delta.Intel just has worse performance and worse thermal performance. Also GPUs usually idle and throttle close to 80 degrees.while cpus get very hot spots.

GPU's are piss easy to cool, the giant bare dies make it so much easier to extract heat from when compared to CPUs which have relatively tiny dies with awful thermal paste transferring the heat to a stupid heat spreader, which finally makes it into the cooler.
