This Apple silicon reveal marks the first time the company has announced an M series chip at the same time as an M Pro and M Max series chip. M1 and M2, for example, were announced months before M1 Pro/Max and M2 Pro/Max chips, respectively.
Apple is also bringing 3 nanometer chip architecture to the Mac for the first time with M3 — like the A17 Pro in iPhone 15 Pro.
GPU improvements are a focus Hardware-accelerated ray tracing Performance per watt improvements: uses roughly 1/2 power to match M1 performance and graphics 16% faster Neural Engine than M2 Up to 128GB RAM for the first time
