And in the case for the M1 Pro, apple is showing it to be faster than the Lenovo 82JW0012US - which has a RTX 3050ti. so the performance could be between RTX 3050ti - RTX 3060. All of this with insanely low power draw.
But still not fanless, right? Maybe they'll update the Macbook Air with some better graphics as well, so that one could do some decent gaming without a fan.
Air is already at the thermal limit range with the 8 core GPU, will probably have to wait until the next real iteration of the technology in the chip (M2 or whatever) which increases efficiency instead of just being larger.
