NVIDIA CMP 50HX Review
NVIDIA CMP 50HX cryptocurrency mining GPU - 8GB GDDR6, Ampere GA104, 225W, no display output, ~45 MH/s legacy Ethereum hashrate
The CMP 50HX was NVIDIA's entry point into Ampere-based mining silicon, built on the same GA104 die family that powers the RTX 3060 Ti and RTX 3070. It kept the CMP formula of no display outputs and mining-tuned firmware, and like every other card in the line, it lost its entire reason to exist when Ethereum abandoned Proof-of-Work mining in September 2022.
What Is a CMP Card, and Why Did It Exist?
Launched in March 2021 alongside the CMP 70HX and CMP 90HX, the CMP 50HX marked NVIDIA's shift from Turing-based mining cards (30HX/40HX) to Ampere-based ones, using a cut-down GA104 die from the same silicon family as the RTX 3060 Ti and RTX 3070. The rationale was unchanged from the rest of the line: crypto miners were buying up GeForce cards during the 2021 shortage, so NVIDIA carved out display-less, mining-only SKUs to preserve gaming GPU supply for gamers, selling them exclusively through mining and system-integrator channels.
Performance & Legacy Status
At launch the CMP 50HX delivered around 45 MH/s mining Ethereum, positioning it as a solid mid-tier option below the 70HX and 90HX. As with the rest of the CMP family, that number is now essentially a historical footnote. Ethereum's Merge to Proof-of-Stake in September 2022 eliminated GPU mining's largest and most lucrative use case almost overnight, and the CMP 50HX today survives only as a cheap, niche secondary-market card for miners of smaller Proof-of-Work coins or hobbyists repurposing it as a compute accelerator. We're honest that this is now a legacy product with limited practical relevance.
Comparison to Alternatives
Within the CMP lineup, the 50HX sits above the Turing-based 30HX/40HX but below the 70HX (a higher-binned version of the same GA104 die) and well below the GA102-based 90HX and A100-derived 170HX. Its closest gaming relative is the RTX 3060 Ti/3070 family, cards that share its core silicon but retain full display output and driver support. For virtually any modern buyer, a used RTX 3060 Ti is the more versatile purchase; the CMP 50HX only makes sense for someone who specifically wants a dedicated, display-less mining or compute card at a lower price point.

Expert rating3.5 / 10
Capable Ampere-generation mining silicon in its day, now a niche secondary-market product with no display output and diminished relevance after Ethereum's Merge.
Best for
- Secondary-market buyers mining non-Ethereum proof-of-work coins
- Repurposing as a cheap compute card for non-graphics CUDA workloads
- Collectors/hobbyists documenting the 2021 mining-boom hardware era
Not for
- Gaming, no display output at all, cannot drive a monitor under any configuration
- Anyone expecting current relevance post-Ethereum Merge (Sept 2022 ended its main use case)
- Buyers who might ever need to repurpose the card as a general-purpose GPU
