AMD Radeon RX 5600 OEM vs NVIDIA CMP 40HX Comparison

Head-to-Head Benchmarks

The recorded data shows a clear and consistent advantage for the NVIDIA CMP 40HX across both benchmark workloads. In the Geekbench OpenCL test, the CMP 40HX scores 93,395 points against the AMD Radeon RX 5600 OEM's 62,427 points, a decisive 49.6% lead. This is not a marginal edge; it is a substantial margin that places the two cards in different performance tiers despite their shared mining-oriented positioning.

The Vulkan results tell a similar story, though with a slightly narrower gap. The NVIDIA CMP 40HX posts 77,879 points, while the AMD Radeon RX 5600 OEM manages 53,743 points. That works out to a 44.9% advantage for the NVIDIA part. It is notably both cards score lower in Vulkan than in OpenCL, but the relative ordering remains unchanged, and the NVIDIA part's lead persists across both API environments.

Looking at the broader database context, the CMP 40HX holds an average benchmark score of 85,637, which places it in the 93rd percentile of all GPUs tracked. The AMD Radeon RX 5600 OEM, by contrast, averages 58,085 and sits in the 87th percentile. The percentile gap is smaller than the raw score gap might suggest, which indicates that the RX 5600 OEM is still a capable performer relative to the wider GPU landscape, but the CMP 40HX is operating in a higher performance bracket altogether.

The nearest rivals for the CMP 40HX reinforce its standing. The AMD Radeon PRO W7600 sits just 1.7% ahead, while the NVIDIA Quadro GP100 is 2.1% ahead. On the other side, the AMD Radeon PRO W6600 trails by 4.4%, and the AMD Radeon Pro Vega 64X trails by 5.8%. These are tight margins, suggesting that the CMP 40HX is positioned squarely in a competitive mid-high tier of workstation and compute-oriented cards.

For the AMD Radeon RX 5600 OEM, the nearest rivals cluster much closer. The Intel Arc A570M is only 0.3% ahead, the AMD Radeon RX 6950 XT is 0.5% ahead, and the NVIDIA P102-100 is 0.8% ahead. The Intel Arc A580 trails by a mere 0.6%. This clustering suggests that the RX 5600 OEM is very much in the middle of a dense pack of similarly performing GPUs, with no clear standout rival either above or below it.

Architecture Differences

The two GPUs are built on fundamentally different architectures and process nodes. The NVIDIA CMP 40HX uses the TU106 chip based on the Turing architecture, fabricated on TSMC's 12 nm process. The die measures 445 mm² and contains 10,800 million transistors, yielding a transistor density of 24.3M per mm². Turing is a mature architecture that includes dedicated ray tracing cores and tensor cores, which the CMP 40HX carries in the form of 36 RT cores and 288 tensor cores. This is notable because the card is a mining product with no display outputs, yet it retains the full compute feature set of the Turing family.

The AMD Radeon RX 5600 OEM, by contrast, uses the Navi 10 chip based on the RDNA 1.0 architecture, also fabricated by TSMC but on a more advanced 7 nm node. The die is much smaller at 251 mm², with 10,300 million transistors, resulting in a transistor density of 41.0M per mm², which is nearly double that of the NVIDIA part. RDNA 1.0 does not include dedicated ray tracing or tensor hardware, and the RX 5600 OEM has neither RT cores nor tensor cores listed in the data.

The process node difference is significant for power efficiency and die size, but the NVIDIA part compensates with a larger die and more specialized compute units. The CMP 40HX also supports DirectX 12 Ultimate (12_2), while the AMD card is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4, so API compatibility is otherwise similar.

Another architectural distinction lies in the bus interface. The NVIDIA CMP 40HX uses PCIe 1.0 x4, which is an unusual and very limited interface, likely because the card is intended for mining rigs rather than general-purpose systems. The AMD Radeon RX 5600 OEM uses PCIe 4.0 x16, a full-bandwidth modern interface. This difference does not impact the benchmark scores recorded, but it does affect how the cards would behave in real-world systems.

Specification Differences

The two cards differ across nearly every major specification category. The NVIDIA CMP 40HX has a base clock of 1470 MHz and a boost clock of 1650 MHz, while the AMD Radeon RX 5600 OEM has a lower base clock of 1130 MHz and a boost clock of 1560 MHz, with a game clock of 1375 MHz. The memory clocks also differ: the CMP 40HX runs at 1750 MHz (14 Gbps effective), while the RX 5600 OEM runs at 1500 MHz (12 Gbps effective).

Memory capacity and configuration are significant differentiators. The CMP 40HX has 8 GB of GDDR6 on a 256-bit bus, delivering 448.0 GB/s of bandwidth. The RX 5600 OEM has 6 GB of GDDR6 on a 192-bit bus, delivering 288.0 GB/s. The NVIDIA part has a clear advantage in both capacity and bandwidth.

Compute resources follow the same pattern. The CMP 40HX has 2304 shading units, 144 texture mapping units, and 64 ROPs. The RX 5600 OEM has 2048 shading units, 128 TMUs, and 64 ROPs. The pixel rates are close, with the CMP 40HX at 105.6 GPixel/s versus 99.84 GPixel/s for the AMD part, but the texture rate gap is wider: 237.6 GTexel/s versus 199.7 GTexel/s. FP32 throughput is 7.603 TFLOPS for the CMP 40HX and 6.390 TFLOPS for the RX 5600 OEM, while FP16 throughput is 15.21 TFLOPS and 12.78 TFLOPS respectively, both at a 2:1 ratio.

Power specifications also differ substantially. The CMP 40HX has a TDP of 185 W and a suggested PSU of 450 W, while the RX 5600 OEM has a TDP of 125 W and a suggested PSU of 300 W. Both are dual-slot cards with a single 8-pin power connector. The CMP 40HX has no display outputs, which is expected for a mining card, while the RX 5600 OEM includes 1x HDMI 2.0b and 3x DisplayPort 1.4a outputs.

Physical dimensions are only available for the NVIDIA part: 229 mm in length, 111 mm in height, and 35 mm in width. The AMD card's dimensions are not recorded. The release dates differ, with the RX 5600 OEM launching in January 2020 and the CMP 40HX in February 2021. The CMP 40HX has a launch MSRP of 699 USD, while no launch MSRP is recorded for the RX 5600 OEM.

Where Each One Wins

The NVIDIA CMP 40HX wins in every recorded benchmark category, and the data indicates it is the stronger performer for compute-heavy workloads. Its advantage in FP32 throughput (7.603 TFLOPS versus 6.390 TFLOPS), texture rate (237.6 GTexel/s versus 199.7 GTexel/s), and memory bandwidth (448.0 GB/s versus 288.0 GB/s) all contribute to its benchmark dominance. The 49.6% lead in OpenCL and 44.9% lead in Vulkan are consistent with these specification advantages.

The CMP 40HX is also the better choice for workloads that can leverage its ray tracing and tensor cores, which the AMD part lacks entirely. Its support for DirectX 12 Ultimate means it can handle the latest graphics feature sets, even though it has no display outputs. For compute tasks such as machine learning inference, cryptographic workloads, or any parallel processing that benefits from higher memory bandwidth and more shading units, the CMP 40HX is clearly superior based on the recorded data.

The AMD Radeon RX 5600 OEM, despite losing all head-to-head benchmarks, still has areas where it holds an advantage in the specification comparison. Its 7 nm process node gives it a much higher transistor density (41.0M per mm² versus 24.3M per mm²), which suggests better power efficiency per transistor. The TDP of 125 W is significantly lower than the CMP 40HX's 185 W, meaning it draws less power and requires a smaller PSU (300 W versus 450 W). For mining operations where power consumption directly impacts profitability, the RX 5600 OEM's efficiency could make it attractive despite its lower raw performance.

The RX 5600 OEM also has a full PCIe 4.0 x16 interface, which is far more flexible than the CMP 40HX's PCIe 1.0 x4. It includes display outputs, so it can be repurposed for gaming or general use after its mining life, something the CMP 40HX cannot do. Its smaller die size (251 mm² versus 445 mm²) likely means lower manufacturing costs, though no pricing data is available for the AMD part.

In practice, the choice between these two cards depends on the specific use case. For maximum compute throughput and memory bandwidth, the NVIDIA CMP 40HX is the clear winner. For lower power consumption, better process efficiency, and the flexibility of display outputs and modern PCIe connectivity, the AMD Radeon RX 5600 OEM has merits that the benchmark scores do not capture. The recorded data, however, is unambiguous: the CMP 40HX outperforms the RX 5600 OEM by roughly 45% to 50% in both OpenCL and Vulkan workloads, and its average benchmark score of 85,637 places it nearly 50% above the RX 5600 OEM's 58,085.
