How can the chip itself consume that kind of power? Or is the 15kw value for the entire unit? That's like 10 residential space heaters all turned to max. I'm surprised that much heat could be dissipated over such a small surface area. Does it use refrigerant for cooling? If my math is correct, if you had a 6500BTU window air conditioner, you'd need 8 of them to move the heat from this chip.
- philjohn 5y agoWell, a single 7nm CPU (AMD Ryzen) can pull down 95 odd watts at peak, granted, the IO die is a fair bit of that as it's on an older process, but if you extrapolate that out across a giant wafer it's "only" 157 Ryzen 7's.
