Which should you buy, AMD Instinct MI100 or Apple M6 GPU?
Buy the AMD Instinct MI100 for buyers comparing AMD's official reference specifications and researching a chip before choosing a board-partner card, though it is the wrong buy for overclocking-focused enthusiasts (reference clocks only). It is the wrong buy for buyers wanting a specific retail card with cooler and warranty details. The Apple M6 GPU suits light gaming and creative app use within the Apple ecosystem. It is equally the pick for buyers comparing a base-tier Mac purchase against a PC build for general use, creative work, or on-device AI tasks. It is not the one for anyone shopping for an upgradeable or swappable PC component, this isn't one. Our rating of the Apple M6 GPU (6/10): Apple's newest base-tier GPU (August 2026), 12 cores with per-core Neural Accelerators, hardware ray tracing, and up to 170GB/s unified memory bandwidth, not a PC-installable component.
