  • They won’t all be interchangeable. They can have totally different max power delivery, and a device is free to require more (up to 240W by spec). The nice thing about USB-PD is it’s negotiated and a device won’t (shouldn’t) try to pull too much power for a given plug. So as long as everyone sticks to specs, they’ll be interchangeable so long as the supply can supply enough. If it cannot, at least a device should keep itself off as if a chord isn’t plugged in, or preferably have some sort of “supply too low” sign.







  • AI isn’t even the first or the twentieth use case for those operations.

    All the “FP” quotes are about floating point precision, which matters more for training and finely detailed models, especially FP64. Integer based matrix math comes up plenty often in optimized cases, which are becoming more and more the norm, especially with China’s research on shrinking models while retaining accuracy metrics.
