Apple M1 Pro (MacBook Pro 2021 32GB UMA)
Overview
Apple M1 Pro is Apple Silicon's 2nd-generation Pro series chip, released on 2021-10-26 for the MacBook Pro 14"/16" 2021. Built on TSMC 5nm (N5) with 33.7 billion transistors, it features 8 or 10 CPU cores (6P+2E or 8P+2E @ 3.2 GHz), 14 or 16 GPU cores, 16-core Neural Engine (11 TOPS), 16/32 GB LPDDR5 unified memory, 200 GB/s memory bandwidth (4× the M1), and Thunderbolt 4. The M1 Pro was Apple's first professional-grade SoC designed for the MacBook Pro, introducing ProRes acceleration, Liquid Retina XDR display, HDMI 2.0, MagSafe 3, and other pro features.
