AMD Instinct MI100 vs AMD Radeon RX 6700: Comparison
Instinct MI100 vs Radeon RX 6700: the memory bandwidth difference
Start with memory bandwidth, because it is the widest measured gap between them: Instinct MI100 1200 GB/s against Radeon RX 6700 320 GB/s, 73% in favour of Instinct MI100. Add tdp to that, 300 W on the Instinct MI100 versus 175 W on the Radeon RX 6700, and the pattern holds. Add boost clock to that, 1502 MHz on the Instinct MI100 versus 2450 MHz on the Radeon RX 6700, and the pattern holds. Instinct MI100 also leads on memory bus width, 4096 bit on the Instinct MI100 versus 160 bit on the Radeon RX 6700. There is a split on compute blocks as well, 120 on the Instinct MI100 versus 36 on the Radeon RX 6700. There is a split on form factor as well, PCIe Add-in Card on the Instinct MI100 versus Component on the Radeon RX 6700.
Instinct MI100 vs Radeon RX 6700: which one fits your build
The Instinct MI100 is the one to take 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). Avoid it for buyers wanting a specific retail card with cooler and warranty details. Buy the Radeon RX 6700 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 the wrong buy for buyers wanting a specific retail card with cooler and warranty details.
