Concrete information about the successor of Apple M1 chip, the M1x surfaced online. This showed that the M1x has huge improvement in both CPU and GPU department compared to Apple M1 chip. Infact, the performance difference is so much that Apple M1x’s GPU performance is comparable to mighty Nvidia GTX 1070.
The Apple M1x processor will be released in second quarter of 2021 and will be used in Macbook Pro 15 and 16” models as well as in iMac 27. This also means no M1x for the current generation Apple Macbook Air.
