NVIDIA CMP 50HX vs NVIDIA GeForce RTX 5080 Comparison

The benchmark data places the NVIDIA GeForce RTX 5080 and the NVIDIA CMP 50HX in completely different performance tiers. In the two shared tests, the RTX 5080 delivers decisive victories, leading by 320.2% in Geekbench OpenCL and 438.4% in Geekbench Vulkan. These are not marginal gains; the RTX 5080's scores of 235,901 and 255,450 dwarf the CMP 50HX's 56,135 and 47,445 respectively. The data shows a generational gap that no amount of driver optimization could close.

Head-to-Head Benchmarks

The head-to-head comparison is limited to two compute-oriented workloads, but the results are unambiguous. In Geekbench OpenCL, the RTX 5080 scores 235,901 against the CMP 50HX's 56,135. That is a 320.2% advantage, meaning the RTX 5080 delivers more than four times the raw compute throughput in this API. The Geekbench Vulkan result is even more lopsided: 255,450 versus 47,445, a 438.4% margin. The RTX 5080's Vulkan score is over five times higher, reflecting a substantial lead in graphics and compute tasks that leverage this modern API.

These deltas are far larger than anything seen in the rivals list. The RTX 5080's nearest rival, the AMD Radeon RX 9070 GRE, sits only 2.2% higher in average score, while the AMD Radeon 8060S is a mere 0.6% behind. The CMP 50HX, by contrast, leads its nearest rival, the AMD Radeon RX 6900 XT, by only 1.6%. The head-to-head margins between the two NVIDIA cards are two orders of magnitude larger than the differences separating either card from its closest competitors. The data indicates the CMP 50HX is not competing in the same weight class.

Architecture Differences

The architectural divide between these two cards is stark. The RTX 5080 uses the GB203 chip built on Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. It packs 45,600 million transistors into a 378 mm² die, yielding a transistor density of 120.6 million per square millimeter. The CMP 50HX, in contrast, uses the TU102 chip from the Turing architecture, built on a 12 nm process at the same foundry. Its 18,600 million transistors occupy a much larger 754 mm² die, resulting in a density of just 24.7 million per square millimeter. The RTX 5080 crams more than twice the transistors into half the physical space.

Memory configurations also diverge sharply. The RTX 5080 features 16 GB of GDDR7 across a 256-bit bus, delivering 960.0 GB/s of bandwidth. The CMP 50HX has 10 GB of GDDR6 on a 320-bit bus, with 560.0 GB/s of bandwidth. Although the CMP 50HX has a wider memory interface, the RTX 5080's faster memory technology gives it a 400 GB/s bandwidth advantage. The RTX 5080 also runs at much higher clocks: 2295 MHz base and 2617 MHz boost versus 1350 MHz base and 1545 MHz boost. This clocks gap, combined with the architectural leap, explains the massive performance delta.

Feature sets reveal their different purposes. The RTX 5080 includes display outputs (1x HDMI 2.1b, 3x DisplayPort 2.1b) and a PCIe 5.0 x16 interface. The CMP 50HX has no display outputs at all, confirming its mining-focused design, and uses a legacy PCIe 1.0 x4 bus. Both support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, but the RTX 5080 doubles the FP32 throughput at 56.28 TFLOPS versus 11.07 TFLOPS. Interestingly, the CMP 50HX has more tensor cores (448 versus 336), but this does not translate into higher compute scores in the tested workloads.

Where Each One Wins

The RTX 5080 wins every shared benchmark, so its strengths are straightforward. It dominates in Geekbench OpenCL and Vulkan, with margins of 320.2% and 438.4% respectively. Its architectural advantages — newer process node, higher clocks, faster memory, and more shading units — make it the clear choice for any compute-heavy workload. The presence of display outputs and a modern PCIe 5.0 interface also makes it suitable for general graphics use, including gaming and professional visualization. Its 87th percentile ranking and average score of 56,083 place it above the vast majority of GPUs.

The CMP 50HX, despite losing every head-to-head test, still holds some distinctions. Its 448 tensor cores exceed the RTX 5080's 336, suggesting a theoretical advantage in tensor-based operations, though the benchmark data does not confirm this in practice. Its lower TDP of 250 W versus 360 W means it draws less power, and its shorter length (267 mm versus 304 mm) makes it more compact. The 2:1 FP16 ratio (22.15 TFLOPS) indicates a different compute profile than the RTX 5080's 1:1 ratio (56.28 TFLOPS). Its 86th percentile ranking shows it remains competitive against its own peers, leading the AMD Radeon RX 6900 XT by 1.6%.

The Verdict

The data points to an unambiguous conclusion. The RTX 5080 is the superior card by every measurable benchmark, with lead margins exceeding 300% in both shared tests. Its architecture is newer, denser, and faster on every front: more transistors, higher clocks, more memory bandwidth, and more shading units. The RTX 5080 is also an active product with display outputs, making it a versatile choice for any graphics workload. The CMP 50HX is end-of-life, lacks display outputs, and uses a legacy PCIe interface.

For users who need maximum compute performance, the RTX 5080 is the only rational pick. Its Geekbench scores are multiples of the CMP 50HX's, and its 87th percentile standing reflects its position among the top GPUs. The CMP 50HX, with its 86th percentile and mining-specific design, serves a narrow niche. Its lower power draw and compact size are its only advantages, but these do not compensate for a five-fold performance deficit in Vulkan. Anyone choosing between these two based on benchmark data should select the RTX 5080 without hesitation. The CMP 50HX's 2.3% lead over the AMD Radeon Pro W5700X in its rivals list suggests it remains functional in its intended role, but that role is not competitive with the RTX 5080.
