When Apple first introduced the M1, questions arose in regards to the variations between it and the A14 chip which each share many architectural options and are each manufactured on TSMC’s 5 nm course of. Semiconductor evaluation agency TechInsights has not too long ago printed die images of the 2 processors and a abstract of the adjustments.
The M1 options 4 high-performance Firestorm cores and 4 energy-efficient IceStorm cores for a complete of eight CPU cores. The A14 solely options six CPU cores with two high-performance Firestorm cores and 4 energy-efficient IceStorm cores. The M1 consists of doubles the quantity of GPU cores and DDR interfaces then discovered on the A14. The M1 additionally incorporates silicon not discovered on the A14 together with the Apple T2 safety processor and different controllers. These additions lead to a die measurement 37% bigger than the A14.
