AMD Radeon RX 5600 OEM vs NVIDIA CMP 30HX Comparison

NVIDIA CMP 30HX and AMD Radeon RX 5600 OEM are both end-of-life graphics cards aimed at different corners of the market, yet benchmark data shows a clear overall winner. The NVIDIA CMP 30HX, a Turing-based mining GPU with no display outputs, edges out the Radeon RX 5600 OEM in both recorded Geekbench tests, taking a 4.4% lead in OpenCL and a commanding 16.3% lead in Vulkan. However, the Radeon RX 5600 OEM, built on RDNA 1.0, counters with a higher theoretical FP32 throughput, more shading units, and a full PCIe 4.0 x16 interface, making it the more versatile card for general compute and gaming workloads despite its lower benchmark scores.

The Verdict

The data splits these two cards into distinct buyer profiles. For anyone needing raw compute performance in OpenCL or Vulkan workloads, the NVIDIA CMP 30HX is the pick: it wins both head-to-head benchmarks, with its Vulkan advantage especially pronounced at 16.3% over the RX 5600 OEM. Its 89th percentile ranking among all GPUs, versus the RX 5600 OEM's 87th, reinforces this edge in aggregate performance. The CMP 30HX also posts a higher average benchmark score of 63,842 compared to 58,085 for the RX 5600 OEM, a gap of roughly 10% in favor of the NVIDIA part.

But the RX 5600 OEM is not without its own rationale. It offers display outputs (1x HDMI 2.0b and 3x DisplayPort 1.4a) while the CMP 30HX has none, meaning the AMD card can actually drive a monitor. For users who need a functional graphics card for everyday use, gaming, or content creation—not just mining or headless compute—the RX 5600 OEM is the only viable choice between the two. Its higher shading unit count (2048 vs 1408) and larger transistor budget (10,300 million vs 6,600 million) suggest greater architectural headroom, even if benchmark results lag. The verdict: choose the CMP 30HX for pure compute performance; choose the RX 5600 OEM if you need a card that can output video.

Where Each One Wins

The CMP 30HX dominates in benchmark scores. In Geekbench OpenCL, it scores 65,199 against the RX 5600 OEM's 62,427, a 4.4% win. In Geekbench Vulkan, the gap widens dramatically: 62,484 versus 53,743, a 16.3% margin. These are the only two head-to-head tests recorded, and the NVIDIA card wins both, giving it a 2-0 record in the wins column. The CMP 30HX also has a higher memory bandwidth at 336.0 GB/s versus 288.0 GB/s, which likely contributes to its compute advantage.

The RX 5600 OEM wins in architectural specifications that don't directly translate to those benchmark scores. It offers higher FP32 performance at 6.390 TFLOPS versus 5.027 TFLOPS, a 27% theoretical advantage. Its texture rate is also higher at 199.7 GTexel/s versus 157.1 GTexel/s, and its pixel rate is 99.84 GPixel/s versus 85.68 GPixel/s. These numbers suggest the AMD card should be faster in pixel-heavy and texture-heavy workloads, even though the Geekbench results tell a different story. The RX 5600 OEM also has a smaller die at 251 mm² despite more transistors, indicating a denser, more modern design on a 7 nm process versus the CMP 30HX's 12 nm process.

Architecture Differences

The two cards represent fundamentally different architectural approaches. The NVIDIA CMP 30HX uses the TU116 chip based on Turing architecture, fabricated on a 12 nm process at TSMC. It packs 6,600 million transistors into a 284 mm² die, yielding a transistor density of 23.2 million per mm². The RX 5600 OEM uses the Navi 10 chip based on RDNA 1.0, also from TSMC but on a more advanced 7 nm process. It contains 10,300 million transistors in a smaller 251 mm² die, achieving a much higher density of 41.0 million per mm².

Memory configurations are similar on the surface: both have 6 GB of GDDR6 on a 192-bit bus. However, the CMP 30HX runs its memory at 1750 MHz (14 Gbps effective) for 336.0 GB/s of bandwidth, while the RX 5600 OEM runs at 1500 MHz (12 Gbps effective) for 288.0 GB/s. Clock speeds also differ: the CMP 30HX has a base clock of 1530 MHz and boost of 1785 MHz, while the RX 5600 OEM has a lower base of 1130 MHz, a boost of 1560 MHz, and a game clock of 1375 MHz. The NVIDIA card also features a PCIe 1.0 x4 interface, a severely limited bus, whereas the RX 5600 OEM uses PCIe 4.0 x16, offering far greater bandwidth for data transfers. Both cards share the same TDP of 125 W, require a 300 W PSU, and use a single 8-pin power connector. The CMP 30HX has no display outputs, while the RX 5600 OEM has a full set including HDMI and DisplayPort.

Head-to-Head Benchmarks

The largest victory in the head-to-head results belongs to the NVIDIA CMP 30HX in Geekbench Vulkan. Its score of 62,484 dwarfs the RX 5600 OEM's 53,743, a delta of 16.3%. This is a significant margin that suggests the Turing architecture's Vulkan driver implementation and memory bandwidth advantage (336.0 GB/s vs 288.0 GB/s) pay off substantially in compute-heavy Vulkan workloads. The CMP 30HX also wins Geekbench OpenCL, but by a narrower 4.4% margin: 65,199 versus 62,427. This smaller gap aligns with the RX 5600 OEM's higher theoretical FP32 throughput, indicating that OpenCL may be more sensitive to raw shader count than Vulkan.

Despite losing both benchmark tests, the RX 5600 OEM shows strengths in other metrics. Its FP32 of 6.390 TFLOPS is 27% higher than the CMP 30HX's 5.027 TFLOPS, and its texture rate of 199.7 GTexel/s beats the NVIDIA card's 157.1 GTexel/s by over 27%. The AMD card's pixel rate of 99.84 GPixel/s also exceeds the CMP 30HX's 85.68 GPixel/s. These numbers suggest that in workloads not captured by the Geekbench tests—such as gaming, ray-traced effects, or specific compute kernels—the RX 5600 OEM could outperform its rival, especially given its full PCIe 4.0 x16 interface versus the CMP 30HX's severely limited PCIe 1.0 x4. The CMP 30HX's higher clock speeds (1785 MHz boost vs 1560 MHz) and bandwidth may compensate in memory-bound tasks, but the RX 5600 OEM's architectural superiority in raw throughput makes it the better-rounded card for traditional graphics workloads.
