I’m interested in such hardware in a steam deck
- bryanlarsen 2y agoI don't think you're going to fit a 45W-115W chip in a Steam deck.
- jauntywundrkind 2y agoCould be wrong but I fully expect these chips to TDP-doen very very very well, as AMD chips have been doing since Ryzen/Epyc first came out. The performance drop off is far less than linear; efficiency climbs and climbs. Even at 20W, I expect this would be an absolutely dominant gaming handheld, if someone was inclined to pack it all in. But what really excited me is the idea that the Deck could Dock to a BFC, Big Fucking Cooler, that let it throttle up to 100+ watts. Good portable power, but then at home it could be a beast.
- bryanlarsen 2y agoSure, it'll likely throttle down, but at 15W it'll likely have similar performance to a 15W AMD mobile chip. So you're running a chip that costs most of $1000 at the performance level of a $200 chip.
- jauntywundrkind 2y agoThe thesis I'll try to state again more clearly is that bigger parts at lower frequencies can trump smaller parts at higher frequencies. Efficiencies increase significantly as you downclock. Sure, a mobile part runs 15w. But it's relatively inefficient at doing so. If you want to drop it to 7w, now you're pretty efficient (Steam Deck lets you TDP down 15 -> 3w!!). But you are too slow for most games. Starting with a big APU with gobs of ram bandwidth and downclocking that system is going to get you much better results from that 15w than using the small part at 15w.
