NVIDIA CMP 90HX vs NVIDIA GeForce RTX 4080 Comparison

The NVIDIA CMP 90HX and the NVIDIA GeForce RTX 4080 share the same manufacturer and TDP, but the recorded benchmark data places them in entirely different performance classes. In the single head-to-head benchmark available, the GeForce RTX 4080 delivers a score of 214,739 in Geekbench OpenCL, while the CMP 90HX scores 69,000. This represents a 67.9% deficit for the mining-oriented card, making the RTX 4080 the decisive winner in every measurable compute scenario.

Head-to-Head Benchmarks

The only direct comparison recorded in the database is the Geekbench OpenCL test. The RTX 4080 more than triples the CMP 90HX’s output, with a delta of -67.9% for the older card. This is not a marginal gap; it is a generational leap in raw compute throughput. The RTX 4080’s score of 214,739 places it well above the CMP 90HX’s 69,000, and the difference is consistent with the architectural and specification chasm between the two.

Looking at the broader database context, the CMP 90HX’s average benchmark score is 69,000, which puts it at the 90th percentile of all GPUs. Its nearest rivals include the Intel Arc A770 at 68,809 (0.3% ahead), the AMD Radeon Instinct MI25 at 68,562 (0.6% ahead), the AMD Radeon Pro WX 8200 at 69,870 (1.2% behind), and the NVIDIA Quadro P6000 at 69,986 (1.4% behind). These are tight margins, indicating the CMP 90HX sits in a competitive mid-range cluster despite its mining-specific design.

The RTX 4080, by contrast, has an average benchmark score of 54,247, but this figure is pulled down by a mix of diverse tests. Its 86th percentile ranking is lower than the CMP 90HX’s 90th, yet the raw Geekbench OpenCL score tells a different story. Its nearest rivals include the RTX 4080 SUPER at 54,209 (0.1% ahead), the AMD Radeon Pro W5700X at 54,828 (1.1% behind), the AMD Radeon RX 6750 GRE 12 GB at 55,698 (2.6% behind), and the AMD Radeon 8060S at 55,757 (2.7% behind). These deltas are small, but the RTX 4080’s individual test scores reveal its true strength: 263,779 in Geekbench Vulkan, 34,457 in Passmark G3D, and 20,671 in Passmark GPU Compute.

The head-to-head data is unambiguous. The RTX 4080 wins the only shared test, and it wins by a margin that dwarfs any rivalry within the CMP 90HX’s own comparison group. The CMP 90HX cannot compete on compute performance; its role in the database is defined by its mining heritage, not its benchmark dominance.

Where Each One Wins

The CMP 90HX wins in one narrow sense: its average benchmark score of 69,000 exceeds the RTX 4080’s average of 54,247, and its 90th percentile rank is higher than the RTX 4080’s 86th. However, this is a statistical artifact of the test mix. The CMP 90HX has a single benchmark entry (Geekbench OpenCL), while the RTX 4080 is subjected to ten different tests, including older DirectX and 2D workloads that pull its average down. In any direct compute comparison, the RTX 4080 wins outright.

For use cases involving raw compute, rendering, or modern API workloads, the RTX 4080 is the clear choice. Its Vulkan score of 263,779 and OpenCL score of 214,739 indicate robust performance in cross-platform graphics and general-purpose compute. The Passmark G3D score of 34,457 reinforces its dominance in 3D rendering tasks. The CMP 90HX, with only a single OpenCL score, offers no data suggesting it can approach these figures.

The CMP 90HX’s strengths lie elsewhere, but not in benchmarking. It has no display outputs, making it unsuitable for conventional gaming or workstation use. Its architecture is designed for mining, and the database records no gaming or professional rendering tests for it. The only scenario where the CMP 90HX “wins” is in the aggregate percentile ranking, which is misleading given the test disparity.

Specification Differences

The two cards diverge on nearly every technical specification. The CMP 90HX uses the GA102 chip on an 8 nm Samsung process, while the RTX 4080 uses the AD103 chip on a 5 nm TSMC process. Transistor counts differ massively: 28,300 million for the CMP 90HX versus 45,900 million for the RTX 4080. Die size also flips the expected trend, with the CMP 90HX at 628 mm² and the RTX 4080 at 379 mm², giving the RTX 4080 a much higher transistor density of 121.1M per mm² versus 45.1M per mm².

Clock speeds favor the RTX 4080: base 2205 MHz versus 1500 MHz, boost 2505 MHz versus 1710 MHz. Memory configurations differ in size and bandwidth. The CMP 90HX has 10 GB of GDDR6X on a 320-bit bus with 760.3 GB/s bandwidth, while the RTX 4080 has 16 GB of GDDR6X on a 256-bit bus with 716.8 GB/s bandwidth. The CMP 90HX actually has higher memory bandwidth, but the RTX 4080 compensates with a 22.4 Gbps effective memory clock versus 19 Gbps.

Compute resources heavily favor the RTX 4080: 9728 shading units versus 6400, 304 TMUs versus 200, 112 ROPs versus 80, 76 RT cores versus 50, and 304 tensor cores versus 200. Pixel rate and texture rate are both higher on the RTX 4080 (280.6 GPixel/s and 761.5 GTexel/s versus 136.8 and 342.0). FP32 and FP16 throughput are more than double on the RTX 4080: 48.74 TFLOPS versus 21.89 TFLOPS.

Physical and interface differences are stark. The CMP 90HX is dual-slot with 2x 8-pin power connectors and a PCIe 1.0 x4 bus interface, while the RTX 4080 is triple-slot with 1x 16-pin power and PCIe 4.0 x16. The RTX 4080 has display outputs (1x HDMI 2.1, 3x DisplayPort 1.4a), while the CMP 90HX has none. Dimensions favor the CMP 90HX in length (285 mm versus 310 mm) and height (112 mm versus 140 mm), but the RTX 4080 adds width (61 mm) where the CMP 90HX has none recorded.

Architecture Differences

The CMP 90HX is built on Ampere architecture, while the RTX 4080 uses Ada Lovelace. This is a fundamental generational divide. The CMP 90HX is part of NVIDIA’s Mining GPUs generation, released on 2021-07-27, while the RTX 4080 belongs to the GeForce 40 series, released on 2022-09-19. The process node shift from 8 nm Samsung to 5 nm TSMC enables the RTX 4080 to pack 45,900 million transistors into a smaller die, resulting in a 121.1M per mm² density versus 45.1M per mm².

The CMP 90HX’s GA102 chip is a larger, older design optimized for mining throughput, with no display outputs and a PCIe 1.0 x4 interface that severely limits data transfer to the host. The RTX 4080’s AD103 chip is designed for consumer graphics, with full display support and PCIe 4.0 x16 connectivity. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical.

The RTX 4080’s architectural advantages translate directly to benchmark scores. Its higher shading unit count (9728 versus 6400) and RT core count (76 versus 50) explain the 67.9% lead in OpenCL compute. The CMP 90HX’s higher memory bandwidth (760.3 GB/s versus 716.8 GB/s) is its only architectural edge, but it does not compensate for the massive compute deficit. The RTX 4080’s tensor core count of 304 versus 200 further cements its lead in AI and machine learning workloads, though no specific benchmarks for that are recorded.

The Verdict

The data is one-sided. The RTX 4080 wins the only head-to-head benchmark by 67.9%, and it offers superior specifications across nearly every category: more shading units, more TMUs, more ROPs, more RT cores, more tensor cores, higher clocks, more memory, and a faster interface. The CMP 90HX holds advantages only in memory bandwidth and physical compactness, neither of which translates to a benchmark win.

Users seeking a graphics card for rendering, gaming, or general compute should choose the RTX 4080. Its Vulkan score of 263,779 and OpenCL score of 214,739 demonstrate exceptional performance in modern APIs. Its 16 GB memory capacity and display outputs make it a functional, versatile product. The launch MSRP of 1,199 USD reflects its position as a high-end consumer card.

Users considering the CMP 90HX should be aware that it is a mining-specific product with no display outputs and a PCIe 1.0 x4 interface. Its single benchmark score of 69,000 places it in the 90th percentile, but that is a solitary data point. The database records no gaming, rendering, or professional application tests for it. Its nearest rivals are all within 1.4%, suggesting it is comparable to mid-range cards from 2021, but it cannot approach the RTX 4080’s performance.

In summary, the RTX 4080 is the definitive choice for any compute or graphics workload. The CMP 90HX is an end-of-life mining card whose only distinction is a higher average percentile, which is an artifact of having fewer tests. For anyone building a system around benchmark performance, the RTX 4080 wins without qualification.
