NVIDIA CMP 50HX vs NVIDIA GeForce RTX 5080 Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains two direct head-to-head comparisons between the NVIDIA CMP 50HX and the NVIDIA GeForce RTX 5080 Mobile, and in both cases the mobile part dominates decisively. The most lopsided result comes in the Geekbench Vulkan test, where the RTX 5080 Mobile scores 169,754 against the CMP 50HX’s 47,445. That is a 72.1% advantage for the mobile GPU, a gap so wide that it places the two products in entirely different performance tiers. The CMP 50HX trails by more than two-thirds in this compute-oriented API workload, which underscores how far the newer architecture has come.

The Geekbench OpenCL result tells a similar story, though with a slightly narrower margin. The RTX 5080 Mobile posts 166,986 points, while the CMP 50HX manages 56,135. The delta here is 66.4% in favor of the mobile part. In absolute terms, the RTX 5080 Mobile delivers nearly three times the OpenCL score of the CMP 50HX. This is not a close contest by any measure. The CMP 50HX, despite being a desktop-class card with a 250 W TDP, cannot keep pace with a laptop GPU that draws only 80 W.

Looking at the broader benchmark landscape, the CMP 50HX does hold a higher average score across all recorded tests. Its average sits at 51,790, which places it in the 86th percentile of all GPUs in the database. The RTX 5080 Mobile, by contrast, averages 38,349 across its benchmark suite, landing in the 81st percentile. This apparent contradiction, where the older card has a higher average yet loses both head-to-head tests, stems from the different benchmark sets recorded for each product. The CMP 50HX only has two Geekbench entries, while the RTX 5080 Mobile has ten tests spanning multiple suites, including several Passmark workloads where scores are numerically lower.

For context on the CMP 50HX’s standing, its nearest rivals in the database include the AMD Radeon RX 6900 XT with an average score of 50,951, a 1.6% difference, and the AMD Radeon RX Vega 64 at 50,001, a 3.6% gap. The NVIDIA GeForce RTX 5070 Ti sits at 49,957, just 3.7% behind, and the Intel Arc A550M rounds out the group at 49,737, a 4.1% delta. These are tight margins, suggesting the CMP 50HX performs in line with those established parts in aggregate.

The RTX 5080 Mobile’s nearest rivals are much closer in average score, with the NVIDIA GeForce MX570 at 38,299 (0.1% difference) and the NVIDIA GeForce RTX 4080 Mobile at 38,135 (0.6% behind). The MX570 A trails by 0.9% at 38,691, and the AMD Radeon Pro 580X is also 0.9% behind at 38,706. These proximity scores indicate that the RTX 5080 Mobile’s aggregate position is heavily weighted by its Passmark entries, which are not directly comparable to the Geekbench numbers that dominate the CMP 50HX’s record.

The Verdict

The data points to a clear winner for anyone prioritizing raw compute performance: the NVIDIA GeForce RTX 5080 Mobile. Its OpenCL score of 166,986 is 197% higher than the CMP 50HX’s 56,135, and its Vulkan score of 169,754 exceeds the CMP 50HX’s 47,445 by 258%. In both direct comparisons, the RTX 5080 Mobile wins by margins of 66.4% and 72.1% respectively. There is no benchmark in the head-to-head record where the CMP 50HX comes out ahead.

However, the CMP 50HX is not without its own merits. Its average benchmark score of 51,790 places it in the 86th percentile of all GPUs, five points higher than the RTX 5080 Mobile’s 81st percentile. The CMP 50HX also sits above its nearest rivals, including the RX 6900 XT and RTX 5070 Ti, in aggregate terms. For workloads that rely on the specific Geekbench tests recorded for both cards, the CMP 50HX outperforms those comparable desktop parts.

The choice depends on the use case. The RTX 5080 Mobile is the better pick for modern compute-heavy tasks where OpenCL and Vulkan performance matter most. The CMP 50HX, with its mining-focused design and no display outputs, is harder to justify in a general-purpose system. Its 10 GB of GDDR6 memory and 560.0 GB/s bandwidth are respectable but lag behind the RTX 5080 Mobile’s 16 GB of GDDR7 and 896.0 GB/s bandwidth. The RTX 5080 Mobile also consumes far less power, with an 80 W TDP versus 250 W for the CMP 50HX, making it the more efficient option on paper.

For a user who already owns a CMP 50HX and runs applications that align with its recorded strengths, the card remains serviceable. But for anyone purchasing new hardware today, the RTX 5080 Mobile offers a significantly higher performance ceiling in the benchmarks that were measured directly. The production status also favors the mobile part: the CMP 50HX is end-of-life, while the RTX 5080 Mobile is listed as active.

Architecture Differences

The two GPUs come from different architectural generations and process nodes, which explains much of the performance gap. The CMP 50HX is built on the Turing architecture using a 12 nm process at TSMC. It packs 18,600 million transistors into a 754 mm² die, yielding a transistor density of 24.7 million per square millimeter. The RTX 5080 Mobile uses the newer Blackwell 2.0 architecture on a 5 nm process, also at TSMC, with 45,600 million transistors on a 378 mm² die. That works out to 120.6 million transistors per square millimeter, nearly five times the density of the Turing part.

The chip designs reflect different priorities. The CMP 50HX uses the TU102 chip, while the RTX 5080 Mobile is built around GB203. The CMP 50HX has 3,584 shading units, 192 texture mapping units, and 80 raster output pipelines. It also includes 56 ray tracing cores and 448 tensor cores. The RTX 5080 Mobile more than doubles the shading unit count to 7,680, with 240 TMUs and 96 ROPs. Its ray tracing core count rises to 60, but its tensor core count drops to 240. The FP32 compute throughput tells the story: the CMP 50HX delivers 11.07 TFLOPS, while the RTX 5080 Mobile reaches 23.04 TFLOPS, a 108% increase.

Memory configurations differ substantially as well. The CMP 50HX uses 10 GB of GDDR6 on a 320-bit bus, with memory clocked at 1750 MHz and 14 Gbps effective. This yields 560.0 GB/s of bandwidth. The RTX 5080 Mobile uses 16 GB of GDDR7 on a 256-bit bus, also at 1750 MHz but with 28 Gbps effective, resulting in 896.0 GB/s of bandwidth. The narrower bus is more than compensated by the faster memory technology.

The FP16 compute rates also diverge. The CMP 50HX achieves 22.15 TFLOPS with a 2:1 ratio to FP32, while the RTX 5080 Mobile hits 23.04 TFLOPS with a 1:1 ratio, meaning it does not gain a throughput advantage in half-precision workloads. Pixel and texture rates favor the mobile part: 144.0 GPixel/s versus 123.6 GPixel/s, and 360.0 GTexel/s versus 296.6 GTexel/s.

Power and physical characteristics are starkly different. The CMP 50HX carries a 250 W TDP, requires dual-slot cooling, uses two 8-pin power connectors, and has a suggested 600 W power supply. It measures 267 mm in length, 116 mm in height, and 35 mm in width. The RTX 5080 Mobile is an integrated graphics package with an 80 W TDP, no power connectors, and no listed dimensions. The CMP 50HX has no display outputs, while the RTX 5080 Mobile’s outputs are dependent on the portable device it ships in. The bus interface also differs: PCIe 1.0 x4 for the CMP 50HX versus PCIe 5.0 x16 for the RTX 5080 Mobile.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The release dates are far apart, with the CMP 50HX launching on June 23, 2021, and the RTX 5080 Mobile arriving on April 1, 2025.

Where Each One Wins

The RTX 5080 Mobile is the clear winner in raw compute performance. Its Geekbench OpenCL score of 166,986 and Vulkan score of 169,754 are both far ahead of the CMP 50HX’s 56,135 and 47,445 respectively. Any workload that relies on these APIs, such as machine learning inference, physics simulation, or GPU-accelerated rendering, will favor the mobile part by a wide margin. The RTX 5080 Mobile also wins on memory capacity and bandwidth, with 16 GB of GDDR7 at 896.0 GB/s versus 10 GB of GDDR6 at 560.0 GB/s. Its higher FP32 throughput of 23.04 TFLOPS, double the CMP 50HX’s 11.07 TFLOPS, makes it the stronger choice for general compute tasks.

The CMP 50HX has advantages in a few specific areas. Its average benchmark score of 51,790 is higher than the RTX 5080 Mobile’s 38,349, and its 86th percentile ranking beats the mobile part’s 81st. In the database, the CMP 50HX also outperforms its nearest rivals, including the AMD Radeon RX 6900 XT and the NVIDIA GeForce RTX 5070 Ti, by margins of 1.6% and 3.7% respectively. For users who already have a CMP 50HX and run applications that were benchmarked in the Geekbench suite, the card remains competitive against those desktop alternatives.

However, the CMP 50HX’s practical appeal is limited by its design. It has no display outputs, making it unsuitable for any system that needs video output. Its end-of-life production status and older Turing architecture mean it lacks the modern features of the Blackwell 2.0-based RTX 5080 Mobile. The mobile part also benefits from a much lower 80 W TDP, making it far more power-efficient despite delivering higher performance.

In terms of API support, both cards match on DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, so there is no differentiator there. The RTX 5080 Mobile’s PCIe 5.0 x16 interface provides a much faster host connection than the CMP 50HX’s PCIe 1.0 x4, which could matter for data transfer-heavy workloads. The newer mobile GPU also has an active production status, while the CMP 50HX is discontinued.

For a typical user choosing between these two, the RTX 5080 Mobile is the better investment. It wins every direct benchmark comparison, offers more memory, higher bandwidth, greater compute throughput, and does so at a fraction of the power draw. The CMP 50HX only makes sense in niche scenarios where its specific benchmark profile is valued and where the lack of display outputs is not a concern, such as dedicated compute arrays that already have separate display adapters. Even then, its 10 GB memory and older architecture put it at a disadvantage in modern workloads. The data is unambiguous: the RTX 5080 Mobile is the superior GPU in every measured head-to-head test.
