AMD Instinct MI100 vs NVIDIA GeForce RTX 3070: Comparison
What is the difference between AMD Instinct MI100 and NVIDIA GeForce RTX 3070?
Start with memory bandwidth, because it is the widest measured gap between them: AMD Instinct MI100 1200 GB/s against NVIDIA GeForce RTX 3070 448 GB/s, 63% in favour of AMD Instinct MI100. Add memory bus width to that, 4096 bit on the AMD Instinct MI100 versus 256 bit on the NVIDIA GeForce RTX 3070, and the pattern holds. Add tdp to that, 300 W on the AMD Instinct MI100 versus 220 W on the NVIDIA GeForce RTX 3070, and the pattern holds. NVIDIA GeForce RTX 3070 also leads on boost clock, 1502 MHz on the AMD Instinct MI100 versus 1725 MHz on the NVIDIA GeForce RTX 3070. There is a split on shader units as well, 7680 on the AMD Instinct MI100 versus 5888 on the NVIDIA GeForce RTX 3070.
AMD Instinct MI100 vs NVIDIA GeForce RTX 3070: which one fits your build
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 not the pick for overclocking-focused enthusiasts (reference clocks only). It is not the one for buyers wanting a specific retail card with cooler and warranty details. Take the NVIDIA GeForce RTX 3070 for 1440p gaming builds that want strong performance-per-dollar from the Ampere generation. Avoid it for buyers planning to use high-res texture mods or run the card for many more years. Our rating of the NVIDIA GeForce RTX 3070 (8/10): A landmark 1440p value card at launch, now defined by its 8GB memory ceiling.
