Architecture Differences

The two GPUs are built on fundamentally different architectures. The NVIDIA CMP 50HX uses the Turing architecture with a TU102 chip, fabricated on a 12 nm process at TSMC. The RTX 3080 Ti uses the newer Ampere architecture with a GA102 chip, manufactured on Samsung's 8 nm node. This process shrink allows the RTX 3080 Ti to pack 28,300 million transistors into a 628 mm² die, whereas the CMP 50HX contains 18,600 million transistors on a larger 754 mm² die. The transistor density tells the story clearly: the RTX 3080 Ti reaches 45.1M transistors per mm², while the CMP 50HX manages only 24.7M per mm².

The compute resources differ dramatically. The RTX 3080 Ti has 10,240 shading units, 320 texture mapping units, and 112 ROPs. The CMP 50HX has 3,584 shading units, 192 TMUs, and 80 ROPs. For ray tracing, the RTX 3080 Ti carries 80 RT cores versus 56 on the CMP 50HX. Tensor core counts also differ: the RTX 3080 Ti has 320 tensor cores, while the CMP 50HX has 448. Interestingly, the mining-focused card has more tensor cores, though the RTX 3080 Ti's Ampere architecture processes FP16 at a 1:1 ratio (34.10 TFLOPS for both FP32 and FP16), while the CMP 50HX achieves 22.15 TFLOPS FP16 at a 2:1 ratio versus 11.07 TFLOPS FP32.

Memory technology also separates the two. The CMP 50HX uses GDDR6 at 14 Gbps effective, while the RTX 3080 Ti uses faster GDDR6X at 19 Gbps effective. The bus widths differ as well: 320-bit for the CMP 50HX and 384-bit for the RTX 3080 Ti. The bandwidth gap is substantial, with the RTX 3080 Ti delivering 912.4 GB/s versus 560.0 GB/s for the CMP 50HX.

The interface and power delivery also reflect their different purposes. The CMP 50HX uses a PCIe 1.0 x4 interface and has no display outputs, consistent with its mining-oriented design. The RTX 3080 Ti uses PCIe 4.0 x16 and provides 1x HDMI 2.1 and 3x DisplayPort 1.4a outputs. The power connectors differ: dual 8-pin on the CMP 50HX versus a single 12-pin on the RTX 3080 Ti. The suggested PSU is also higher for the RTX 3080 Ti at 750 W versus 600 W for the CMP 50HX.

Head-to-Head Benchmarks

The database records two direct head-to-head benchmark comparisons between these GPUs, and the RTX 3080 Ti wins both decisively.

In Geekbench OpenCL, the RTX 3080 Ti scores 170,037 against the CMP 50HX's 56,135. This represents a delta of -67% for the CMP 50HX, meaning the RTX 3080 Ti is roughly three times faster in this compute workload. The OpenCL test exercises general-purpose compute across the GPU, and the RTX 3080 Ti's advantage comes from its much higher shading unit count and faster memory subsystem.

The Geekbench Vulkan result shows an even larger gap. The RTX 3080 Ti scores 192,697, while the CMP 50HX manages only 47,445. The delta here is -75.4%, indicating the RTX 3080 Ti delivers over four times the performance in this graphics API workload. Vulkan is a low-level API that benefits from raw hardware throughput, and the RTX 3080 Ti's Ampere architecture, with its 10,240 shading units and higher clock speeds, dominates.

The RTX 3080 Ti also has a wider benchmark portfolio in the database. Beyond the two shared tests, it records scores in 3DMark Steel Nomad DX12 (5,077), Passmark DirectX 10 (184), DirectX 11 (223), DirectX 12 (110), DirectX 9 (274), G2D (1,091), G3D (26,896), and GPU Compute (15,282). The CMP 50HX has no additional recorded benchmarks beyond the two Geekbench tests.

Despite losing both head-to-head tests, the CMP 50HX holds a higher average benchmark score across all recorded tests: 51,790 versus 41,187 for the RTX 3080 Ti. This apparent contradiction is explained by the different test sets: the CMP 50HX's average is based on only two Geekbench scores, while the RTX 3080 Ti's average includes the much lower Passmark scores, which use different scoring scales. The percentile ranking reflects this: the CMP 50HX sits at the 86th percentile, while the RTX 3080 Ti is at the 83rd.

Specification Differences

The recorded specifications show clear differences across nearly every category.

Process and Die: The CMP 50HX uses a 12 nm process from TSMC with an 18,600 million transistor count on a 754 mm² die. The RTX 3080 Ti uses an 8 nm process from Samsung with 28,300 million transistors on a 628 mm² die. Density differs at 24.7M per mm² versus 45.1M per mm².

Where Each One Wins

The RTX 3080 Ti wins decisively in raw graphics and compute performance. Its Geekbench Vulkan score of 192,697 is more than four times the CMP 50HX's 47,445. The OpenCL result shows a similar pattern, with the RTX 3080 Ti at 170,037 versus 56,135. The RTX 3080 Ti also has a much larger memory bandwidth (912.4 GB/s versus 560.0 GB/s), more shading units, higher boost clock (1665 MHz versus 1545 MHz), and twice the FP32 throughput (34.10 TFLOPS versus 11.07 TFLOPS). For any gaming or graphics-intensive workload, the RTX 3080 Ti is the clear choice based on these measurements. It also has display outputs, making it usable for standard desktop and gaming scenarios.

The CMP 50HX wins in average benchmark score (51,790 versus 41,187) and percentile ranking (86th versus 83rd). However, this is driven by its limited benchmark set of only two Geekbench tests. The CMP 50HX also has a lower TDP at 250 W versus 350 W, which could be relevant for power-constrained environments. It has more tensor cores (448 versus 320), though this does not translate to a benchmark win in the recorded data. Its smaller physical footprint (267 mm versus 285 mm length) and lower suggested PSU (600 W versus 750 W) make it less demanding on system power delivery. The CMP 50HX has no display outputs, so it is unsuitable for any use case requiring video output.

The Verdict

The data clearly favors the NVIDIA GeForce RTX 3080 Ti for any workload requiring graphics output or maximum compute throughput. It wins both head-to-head benchmarks by wide margins (67% in OpenCL, 75.4% in Vulkan), has over three times the FP32 throughput, and provides more than 60% higher memory bandwidth. Its 12 GB of GDDR6X memory, 80 RT cores, and 10,240 shading units make it a substantially more capable card for gaming, rendering, and general GPU compute. The launch MSRP of 1,199 USD reflects its positioning as a high-end consumer product.

The NVIDIA CMP 50HX was designed for a specific purpose: mining. Its lack of display outputs, PCIe 1.0 x4 interface, and higher tensor core count all point to compute-oriented tasks rather than graphics. Its higher average benchmark score (51,790) and percentile rank (86th) are notable, but these figures come from a limited test set. For anyone choosing between these two cards, the RTX 3080 Ti is the better choice for gaming, content creation, or any task requiring video output. The CMP 50HX might be considered for specialized compute roles where its lower power draw (250 W versus 350 W) and smaller footprint matter, but its benchmark deficits in every shared test make it difficult to recommend for general use. The RTX 3080 Ti's successor in the GeForce 40 series and the CMP 50HX's end-of-life status mean neither card represents a forward-looking purchase, but within the recorded data, the RTX 3080 Ti is the superior performer.
