AMD Instinct MI100 vs AMD Radeon RX 6700 XT: Comparison
Instinct MI100 vs Radeon RX 6700 XT: the memory bandwidth difference
On memory bandwidth the spread is 68%, Instinct MI100 1200 GB/s against Radeon RX 6700 XT 384 GB/s, so Instinct MI100 takes it. Radeon RX 6700 XT also leads on boost clock, 1502 MHz on the Instinct MI100 versus 2581 MHz on the Radeon RX 6700 XT. Add memory bus width to that, 4096 bit on the Instinct MI100 versus 192 bit on the Radeon RX 6700 XT, and the pattern holds. Tdp runs the same way, 300 W on the Instinct MI100 versus 230 W on the Radeon RX 6700 XT, another win for Radeon RX 6700 XT. Shader units is not the same on both, 7680 on the Instinct MI100 versus 2560 on the Radeon RX 6700 XT. They differ on compute blocks too, 120 on the Instinct MI100 versus 40 on the Radeon RX 6700 XT.
Instinct MI100 vs Radeon RX 6700 XT: which one fits your build
The Instinct MI100 suits 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). Avoid it for buyers wanting a specific retail card with cooler and warranty details. Buy the Radeon RX 6700 XT for 1440p gaming builds that prioritize rasterization performance and VRAM capacity, though it is not built for buyers who want strong ray tracing or DLSS-equivalent upscaling. Our rating of the Radeon RX 6700 XT (8/10): strong 1440p rasterization with 12GB of VRAM, weaker in ray tracing and upscaling.
