AMD Instinct MI100 vs NVIDIA RTX A2000: Comparison
What is the difference between AMD Instinct MI100 and NVIDIA RTX A2000?
On tdp the spread is 329%, AMD Instinct MI100 300 W against NVIDIA RTX A2000 70 W, so NVIDIA RTX A2000 takes it. Memory bandwidth runs the same way, 1200 GB/s on the AMD Instinct MI100 versus 288 GB/s on the NVIDIA RTX A2000, another win for AMD Instinct MI100. NVIDIA RTX A2000 also leads on slot width, 2 on the AMD Instinct MI100 versus 1 on the NVIDIA RTX A2000. Add memory bus width to that, 4096 bit on the AMD Instinct MI100 versus 192 bit on the NVIDIA RTX A2000, and the pattern holds. Card length runs the same way, 267 mm on the AMD Instinct MI100 versus 168 mm on the NVIDIA RTX A2000, another win for NVIDIA RTX A2000. AMD Instinct MI100 also leads on boost clock, 1502 MHz on the AMD Instinct MI100 versus 1200 MHz on the NVIDIA RTX A2000.
AMD Instinct MI100 vs NVIDIA RTX A2000: which one fits your build
The AMD 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). It is not the one for buyers wanting a specific retail card with cooler and warranty details. The NVIDIA RTX A2000 suits small-form-factor CAD and engineering workstations and entry-level CUDA-accelerated professional software, though it is not built for heavy rendering or simulation workloads and large VRAM-hungry AI models (see the 12GB variant instead).

Which one should you pick?
Choose AMD Instinct MI100 if you want the higher boost clock (1502 MHz vs 1200 MHz), the higher memory bus width (4096 bit vs 192 bit) and the higher memory bandwidth (1200 GB/s vs 288 GB/s).
Choose NVIDIA RTX A2000 if you want the lower TDP (70 W vs 300 W), the lower card length (168 mm vs 267 mm) and the lower slot width (1 vs 2).
Verdict
NVIDIA RTX A2000
6.7 / 10 Expert Rating
The default sensible pick for CAD-capable small-form-factor workstations that don't need heavy rendering or simulation horsepower.
