The Xbox Series X heatsink in their teardown looks to be less than half the size. I'm guessing the larger heatsink is to make sure the console survives long enough to make up for the massive losses this generation. It's possible that they need a larger heatsink due to overclocks. Maybe they plan to reuse the same system with an upgraded "pro" chip and wanted to save design and tooling costs. Maybe it's just the normal conservative design choice common in Japanese companies. Some interesting room to conjecture. EDIT: 315w for xbox vs 350w for PS4 isn't that big of a difference. In any case, massive graphics cards like the GTX480 or those old AMD dual 4xxx/5xxx cooled more than 350w with a much smaller heatsink (though in a larger case with better airflow -- though not all of that power goes just to the CPU/GPU in the consoles).
