With its new M1 Pro and M1 Max chips, Apple declares all-out war on PCs, with a huge boost in performance, while sending battery consumption to the basement. The M1 Max is clearly gunning for the graphics professionals out there, but may also turn out to bring some more gaming capabilities to the Mac.

The M1 Max builds on the M1 Pro architecture, but adds a lot more oomph to the mix. The architecture features much higher bandwidth – up to 400GB/sec of memory bandwidth, which works out to about six times faster than the already blazingly fast M1 chip – and twice as fast as the just-announced M1 Pro chip.
