AMD Instinct MI250 vs NVIDIA CMP 70HX: Comparison
AMD Instinct MI250 vs NVIDIA CMP 70HX tdp compared
On tdp the spread is 100%, AMD Instinct MI250 500 W against NVIDIA CMP 70HX 250 W, so NVIDIA CMP 70HX takes it. Memory bandwidth runs the same way, 3200 GB/s on the AMD Instinct MI250 versus 448 GB/s on the NVIDIA CMP 70HX, another win for AMD Instinct MI250. AMD Instinct MI250 also leads on memory bus width, 8192 bit on the AMD Instinct MI250 versus 256 bit on the NVIDIA CMP 70HX. They differ on tier too, Datacenter on the AMD Instinct MI250 versus Upper-Mid Mining on the NVIDIA CMP 70HX. There is a split on architecture as well, CDNA2 on the AMD Instinct MI250 versus Ampere , a higher-binned version of the same die... on the NVIDIA CMP 70HX.
Who each one is for
The AMD Instinct MI250 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 not the pick for overclocking-focused enthusiasts (reference clocks only). Avoid it for buyers wanting a specific retail card with cooler and warranty details. The NVIDIA CMP 70HX suits secondary-market buyers mining non-Ethereum proof-of-work coins and repurposing as a cheap compute card for non-graphics CUDA workloads. It is not the one for gaming, no display output at all, cannot drive a monitor under any configuration. Our rating of the NVIDIA CMP 70HX (4/10): one of the more efficient cards in NVIDIA's original CMP lineup, but still a legacy mining-only product whose core use case ended with Ethereum's Merge.
Frequently asked questions
