NVIDIA CMP 50HX vs NVIDIA GeForce RTX 4080 Comparison

# NVIDIA GeForce RTX 4080 vs NVIDIA CMP 50HX

The RTX 4080 and CMP 50HX are both NVIDIA products, but they target completely different workloads. The RTX 4080 is a GeForce 40-series consumer graphics card built on the Ada Lovelace architecture, while the CMP 50HX is a dedicated mining GPU from the Turing generation. Benchmark data shows the RTX 4080 dominates in compute and graphics tests, with a 282.5% lead in Geekbench OpenCL and a 456% lead in Geekbench Vulkan. The CMP 50HX, despite having no display outputs and a mining-focused design, still holds an 86th percentile ranking among all GPUs, but its average benchmark score of 51,790 trails the RTX 4080's 54,247.

The Verdict

The RTX 4080 is the clear choice for anyone needing a full-featured graphics card with display outputs, ray tracing capabilities, and substantially higher compute performance. Its average benchmark score of 54,247 places it 4.7% above the CMP 50HX's 51,790, and it wins both head-to-head benchmark tests decisively. The Geekbench OpenCL score of 214,739 versus 56,135 represents a 282.5% advantage, while the Vulkan score of 263,779 versus 47,445 shows a 456% gap. For gaming, content creation, or any workload requiring visual output, the RTX 4080 is the only viable option between these two.

The CMP 50HX, with no display outputs and a PCIe 1.0 x4 interface, is strictly a compute-oriented product. Its 11.07 TFLOPS FP32 performance and 22.15 TFLOPS FP16 performance are far below the RTX 4080's 48.74 TFLOPS in both precision formats. However, the CMP 50HX does offer a dual-slot form factor and a lower 250 W TDP compared to the RTX 4080's 320 W. The data suggests the CMP 50HX is only suitable for specialized compute tasks where display output and consumer features are irrelevant, and even then, its performance is significantly lower than the RTX 4080.

Architecture Differences

The two GPUs come from different architectural generations. The RTX 4080 uses the AD103 chip built on the Ada Lovelace architecture with a 5 nm process at TSMC, packing 45,900 million transistors into a 379 mm² die. The CMP 50HX uses the TU102 chip from the older Turing architecture, manufactured on a 12 nm process at TSMC, with 18,600 million transistors spread across a much larger 754 mm² die. This results in drastically different transistor densities: 121.1 million per mm² for the RTX 4080 versus 24.7 million per mm² for the CMP 50HX.

Core configurations also differ substantially. The RTX 4080 features 9,728 shading units, 304 texture mapping units, 112 raster output pipelines, 76 ray tracing cores, and 304 tensor cores. The CMP 50HX has 3,584 shading units, 192 TMUs, 80 ROPs, 56 ray tracing cores, and 448 tensor cores. Notably, the CMP 50HX has more tensor cores than the RTX 4080, but its overall shading and texture capabilities are far lower. The RTX 4080's pixel rate of 280.6 GPixel/s and texture rate of 761.5 GTexel/s dwarf the CMP 50HX's 123.6 GPixel/s and 296.6 GTexel/s.

Clock speeds reflect the architectural differences. The RTX 4080 runs at a base clock of 2205 MHz and boost clock of 2505 MHz, while the CMP 50HX operates at 1350 MHz base and 1545 MHz boost. Memory configurations also differ: the RTX 4080 uses 16 GB of GDDR6X on a 256-bit bus with 716.8 GB/s bandwidth, while the CMP 50HX has 10 GB of GDDR6 on a 320-bit bus with 560.0 GB/s bandwidth. The RTX 4080's memory runs at 22.4 Gbps effective, compared to 14 Gbps effective on the CMP 50HX.

Head-to-Head Benchmarks

The benchmark results show a one-sided contest. In Geekbench OpenCL, the RTX 4080 scores 214,739 against the CMP 50HX's 56,135, a 282.5% advantage. This massive delta reflects the RTX 4080's superior compute throughput, with its 48.74 TFLOPS FP32 performance more than quadrupling the CMP 50HX's 11.07 TFLOPS. The gap in Geekbench Vulkan is even more pronounced: the RTX 4080 scores 263,779 versus 47,445, representing a 456% lead. This suggests the RTX 4080's Vulkan driver implementation and hardware capabilities provide an outsized advantage in this API.

The RTX 4080 also wins on aggregate metrics. Its average benchmark score of 54,247 exceeds the CMP 50HX's 51,790 by 4.7%. However, notably, the CMP 50HX's nearest rivals include the AMD Radeon RX 6900 XT (1.6% behind), AMD Radeon RX Vega 64 (3.6% behind), and NVIDIA GeForce RTX 5070 Ti (3.7% behind). Meanwhile, the RTX 4080's nearest rivals are the RTX 4080 SUPER (0.1% ahead), AMD Radeon Pro W5700X (1.1% ahead), and AMD Radeon RX 6750 GRE 12 GB (2.6% ahead). This places the CMP 50HX in more competitive company despite its mining-focused design, though the RTX 4080 maintains a clear edge.
