NVIDIA CMP 50HX vs NVIDIA GeForce RTX 5090 Comparison

Where Each One Wins

The benchmark data makes the separation between these two NVIDIA cards unambiguous. The GeForce RTX 5090 wins every recorded head-to-head test, and it wins by margins that are not close. In the two shared benchmarks, Geekbench OpenCL and Geekbench Vulkan, the RTX 5090 leads by 495.7% and 694% respectively. The CMP 50HX, a Turing-era mining card with no display outputs, does not claim a single win in any common test.

The RTX 5090 is the clear choice for any workload that touches general-purpose compute, graphics acceleration, or API-level performance. Its OpenCL score of 334,370 versus the CMP 50HX's 56,135 shows that the gap is not incremental but generational. In Vulkan, the RTX 5090 scores 376,728 against 47,445 for the CMP 50HX. The RTX 5090 also holds a 92nd percentile ranking among all GPUs in the database, while the CMP 50HX sits at the 86th percentile. That percentile gap matters: the RTX 5090 is near the top of the entire field, whereas the CMP 50HX is merely above average.

The CMP 50HX does have one structural advantage: it was designed for mining, not rendering. It has no display outputs, which means it cannot drive a monitor. That is not a performance win, but it is a use-case split. If the task is purely compute without any visual output requirement, the CMP 50HX can operate in that niche. However, the recorded data shows that even in raw compute, the RTX 5090 dwarfs it. The average benchmark score for the RTX 5090 is 79,842, while the CMP 50HX averages 51,790. That is a 54% advantage in average score, and it comes from a card that also supports full display output and modern APIs.

Architecture Differences

The architectural gulf between these two cards is vast. The RTX 5090 uses the GB202 chip built on Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. It packs 92,200 million transistors into a 750 mm² die, giving a transistor density of 122.9 million per mm². The CMP 50HX uses the TU102 chip on the Turing architecture, built on a 12 nm process, also at TSMC. It contains 18,600 million transistors on a 754 mm² die, yielding a density of just 24.7 million per mm². The die sizes are nearly identical (750 vs 754 mm²), but the RTX 5090 crams nearly five times more transistors into that space.

The memory subsystems are equally divergent. The RTX 5090 ships with 32 GB of GDDR7 on a 512-bit bus, delivering 1.79 TB/s of bandwidth. The CMP 50HX has 10 GB of GDDR6 on a 320-bit bus, producing 560.0 GB/s. That is a 3.2x bandwidth advantage for the RTX 5090. Clock speeds also differ: the RTX 5090 runs at a base of 2017 MHz and boosts to 2407 MHz, while the CMP 50HX runs at 1350 MHz base and 1545 MHz boost. Memory clock is 1750 MHz on both, but the effective data rate is 28 Gbps on the RTX 5090 versus 14 Gbps on the CMP 50HX.

Compute resources tell the same story. The RTX 5090 has 21,760 shading units, 680 texture mapping units, 176 ROPs, 170 RT cores, and 680 tensor cores. The CMP 50HX has 3,584 shading units, 192 TMUs, 80 ROPs, 56 RT cores, and 448 tensor cores. The FP32 throughput is 104.8 TFLOPS on the RTX 5090 versus 11.07 TFLOPS on the CMP 50HX. The RTX 5090 also offers 1:1 FP16 at 104.8 TFLOPS, while the CMP 50HX offers 2:1 FP16 at 22.15 TFLOPS. Pixel rate is 423.6 GPixel/s versus 123.6 GPixel/s, and texture rate is 1,636.8 GTexel/s versus 296.6 GTexel/s.

The CMP 50HX uses a PCIe 1.0 x4 interface, which is a severe bottleneck for any data transfer. The RTX 5090 uses PCIe 5.0 x16. The CMP 50HX has no display outputs, while the RTX 5090 offers 1x HDMI 2.1b and 3x DisplayPort 2.1b. Power requirements also differ: the RTX 5090 has a 575 W TDP and requires a 950 W PSU with a single 16-pin connector, while the CMP 50HX has a 250 W TDP and needs a 600 W PSU with two 8-pin connectors. The RTX 5090 is 304 mm long, 137 mm tall, and 40 mm wide; the CMP 50HX is 267 mm long, 116 mm tall, and 35 mm wide.

Head-to-Head Benchmarks

Only two benchmark tests were recorded for both cards, and the RTX 5090 wins both. In Geekbench OpenCL, the RTX 5090 scores 334,370 against 56,135 for the CMP 50HX. That is a 495.7% delta, meaning the RTX 5090 delivers roughly six times the OpenCL performance. In Geekbench Vulkan, the RTX 5090 scores 376,728 against 47,445, a 694% delta. The Vulkan gap is even larger than the OpenCL gap. These are not marginal wins; they are complete overhauls of the compute pipeline.

The RTX 5090 also has a broader benchmark footprint in the database. It has recorded scores for 3DMark Steel Nomad DX12 (18,355), Passmark DirectX 10 (226), DirectX 11 (341), DirectX 12 (185), DirectX 9 (395), Passmark G2D (1,413), Passmark G3D (39,650), and Passmark GPU Compute (26,756). The CMP 50HX has no scores in any of those tests. That means the CMP 50HX cannot be compared on DirectX or Passmark workloads at all. The only common ground is the two Geekbench tests, and the RTX 5090 dominates both.

Average benchmark scores reinforce the pattern. The RTX 5090 averages 79,842 across all recorded tests, while the CMP 50HX averages 51,790. That is a 54% advantage for the RTX 5090 in aggregate performance. The nearest rivals for the RTX 5090 are the Tesla P100 PCIe 16 GB (79,605, 0.3% behind) and the Tesla P100 PCIe 12 GB (79,396, 0.6% behind). The RTX 5090 is effectively tied with those cards in average score, but it beats them on modern API support. The CMP 50HX's nearest rivals are the RX 6900 XT (50,951, 1.6% behind), RX Vega 64 (50,001, 3.6% behind), RTX 5070 Ti (49,957, 3.7% behind), and Arc A550M (49,737, 4.1% behind). The CMP 50HX leads those cards by small margins, but it is nowhere near the RTX 5090.

The Verdict

The data points to one conclusion: the RTX 5090 is the superior card by every measurable metric. It wins both head-to-head benchmarks, has a higher average score, holds a higher percentile rank, and offers modern features like display outputs, PCIe 5.0, and full API support. The CMP 50HX is an end-of-life mining card with no display outputs, a PCIe 1.0 x4 interface, and a fraction of the compute resources. If the choice is between these two, the RTX 5090 is the only sensible pick for any workload that involves rendering, graphics, or general compute.

The CMP 50HX does have one narrow use case: it can run in a mining rig where display output is irrelevant and power draw is a concern. Its 250 W TDP is lower than the RTX 5090's 575 W, and its PCIe 1.0 x4 interface is sufficient for mining workloads that do not move large amounts of data. But even in that niche, the RTX 5090's compute advantage is so large that it would outperform the CMP 50HX on any compute task that can use its resources. The CMP 50HX is not a competitor; it is a relic.

For users who need a card for gaming, content creation, or any modern graphics workload, the RTX 5090 is the only option with display outputs and current API support. Its launch MSRP is 1,999 USD. The CMP 50HX has no launch MSRP recorded. The RTX 5090's 92nd percentile ranking among all GPUs puts it near the top of the database, while the CMP 50HX's 86th percentile is solid but unexceptional. The verdict is straightforward: the RTX 5090 wins outright.
