AMD Radeon Pro W6600M vs NVIDIA CMP 50HX Comparison

Head-to-Head Benchmarks

The recorded data shows a clear, if lopsided, contest between these two end-of-life products. Across the two benchmark tests in the database, the AMD Radeon Pro W6600M takes both wins, with a final tally of 2 wins to 0. The most dramatic separation occurs in the Geekbench Vulkan test, where the AMD part posts a score of 67,652 against the NVIDIA CMP 50HX's 47,445. That is a 42.6% advantage for the AMD Radeon Pro W6600M, a massive margin that points to a fundamental difference in how these two cards handle modern graphics APIs.

The OpenCL results, by contrast, are almost dead even. The AMD Radeon Pro W6600M scores 56,140, while the NVIDIA CMP 50HX scores 56,135. The delta is recorded as 0%, which makes this a technical tie. The difference of five points out of more than fifty-six thousand is statistically negligible, and any conclusion drawn from that test alone would be subject to run-to-run variance. But the Vulkan result is not close, and it shifts the overall picture decisively.

Looking at the average benchmark score, the AMD Radeon Pro W6600M sits at 61,896, which places it in the 89th percentile of all GPUs in the database. The NVIDIA CMP 50HX, with an average score of 51,790, sits in the 86th percentile. That is a three-percentile gap, and it roughly corresponds to the difference in raw average score: the AMD part is about 19.5% ahead of the NVIDIA part on average, a substantial lead in overall compute performance.

The nearest rival data reinforces how each card fits into the broader landscape. The AMD Radeon Pro W6600M's closest competitor is the AMD Radeon 8050S, which averages 62,108, a delta of -0.3% relative to the W6600M. That means the W6600M is essentially a dead heat with that chip. It also edges out the NVIDIA GeForce RTX 4090, which averages 60,347, a 2.6% gap in favor of the W6600M. The Intel Arc Pro A60 scores 60,326, matching the RTX 4090 delta of 2.6% ahead of the W6600M. The AMD Radeon Pro Vega 48 is 2.9% behind the W6600M, scoring 60,140.

The NVIDIA CMP 50HX's nearest rivals tell a different story. Its closest rival, the AMD Radeon RX 6900 XT, averages 50,951, putting the CMP 50HX 1.6% ahead of that part. The AMD Radeon RX Vega 64 is 3.6% ahead of the CMP 50HX. The NVIDIA GeForce RTX 50 70 Ti is 3.7% ahead of the CMP 50HX. Intel Arc A550M is 4.1% ahead of the CMP 50HX. Notably, this means the CMP 50HX is surrounded by faster rivals on both sides, but its own average score of 51,790 is barely above the RX 6900 XT's 50,951.

The Vulkan score is where the two diverge most sharply, and it is also where the architectural differences become visible. The AMD Radeon Pro W6600M's 28 ray accelerators, part of its RDNA 2.0 design, clearly translate into better low-level GPU compute performance in this specific test. The NVIDIA CMP 50HX, despite having 56 ray tracing cores and 448 tensor cores, cannot match that Vulkan output.

The OpenCL result, near parity, suggests that raw shading power, texture rate, and pixel throughput are not the deciding factors. The data shows the AMD part hits 227.8 GTexel/s and 130.2 GPixel/s, while the NVIDIA part reaches 296.6 GTexel/s and 123.6 GPixel/s. Yet OpenCL scores are within five points. In Vulkan, where driver overhead is lower and the API access is more direct, the AMD part runs away with it. This pattern points to the NVIDIA card being held back by its architecture in this API, an inference supported by its 56 ray tracing cores per cluster, a design choice from the Turing generation that does not shine in Vulkan.

The Verdict

From the data alone, the AMD Radeon Pro W6600M is the outright winner of this comparison. It wins both head-to-head tests, holds a higher average score, and ranks higher in percentile standing, 89th percentile versus 86th. For any workload that leans on Vulkan performance, the choice is unambiguous, AMD Radeon Pro W6600M, by 42.6%. For OpenCL, where the two are effectively tied at 0%, the AMD part wins by a hair, but the practical takeaway from the benchmarks is that both cards perform nearly identically in OpenCL and the AMD part dominates in Vulkan.

The AMD Radeon Pro W6600M should be chosen by anyone who needs a GPU for general compute tasks that favor Vulkan. The NVIDIA CMP 50HX's 10 GB of GDDR6 memory, 320-bit bus interface, and 560.0 GB/s of bandwidth are not enough to overcome the AMD part's Vulkan advantage. The NVIDIA CMP 50HX also presents practical constraints in a system context, a dual-slot design with 2x 8-pin power connectors 2x 8-pin, and requires a 600 W power supply, while the AMD part is an IGP with no power connectors, making it far easier to integrate into existing systems. The NVIDIA card measures 267 mm, 116 mm, 35 mm, and carries 18,600 million transistors on a 754 mm² die size, but that does not translate to wins in these tests. The AMD Radeon Pro W6600M, built on a 7 nm process node from TSMC, with 11,060 million transistors, 1,792 shading units, and 237 mm² die, carries 7.290 TFLOPS FP32 throughput, while offering 14.58 TFLOPS FP16 (2:1) performance. The NVIDIA CMP 50HX delivers 11.07 TFLOPS FP32, 22.16 TFLOPS FP16 (2:1), and also 56 ray tracing cores, 448 tensor cores, with 80 ROPs and 192 TMUs. None of that shows up in the measured results, aside from Vulkan where NVIDIA lags by 42.6%, which is a 42.6% margin for the AMD part.

The verdict is that the AMD Radeon Pro W6600M is the stronger card, strictly by the recorded numbers. The NVIDIA CMP 50HX does not win a single test in the head-to-head comparison. Its only saving grace, if any, is the OpenCL parity, where the delta is 0% and the score difference is five points. For anyone deciding between these two, the data says pick the AMD Radeon Pro W6600M.

The transistor density reflects this: 46.7M per mm² for AMD, 24.7M per mm² for NVIDIA.

Memory configurations differ sharply. The AMD card has 8 GB of GDDR6 on a 128-bit bus, delivering 224.0 GB/s bandwidth. The NVIDIA card has 10 GB of GDDR6 on a 320-bit bus, delivering 560.0 GB/s bandwidth. Memory clock is the same, 1750 MHz with 14 Gbps effective, but the wider bus gives NVIDIA the bandwidth advantage.

Clock speeds also differ. The AMD card has a base clock of 1224 MHz and a boost clock of 2034 MHz. The NVIDIA card has a base clock of 1350 MHz and a boost clock of 1545 MHz. The AMD card starts lower but boosts much higher.

Compute resources differ significantly. The AMD card has 1,792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores. The NVIDIA card has 3,584 shading units, 192 TMUs, 80 ROPs, 56 ray tracing cores, and 448 tensor cores. Despite having half the shading units, the AMD card posts higher or equal benchmark results in the tested workloads.

The power and physical profiles are very different. The AMD Radeon Pro W6600M is rated at 90 W TDP, is an IGP form factor, and has no power connectors. The NVIDIA CMP 50HX is rated at 250 W TDP, is a dual-slot card, requires 2x 8-pin power connectors, and has a suggested PSU of 600 W. The NVIDIA card measures 267 mm in length, 116 mm in height, and 35 mm in width.

The bus interface differs as well. The AMD card runs PCIe 4.0 x16, while the NVIDIA card runs PCIe 1.0 x4, a significant interface limitation. Display outputs also differ: the AMD card is portable device dependent, while the NVIDIA card has no display outputs at all. The release dates are close, with the AMD card released on 2021-06-07 and the NVIDIA card on 2021-06-23.

Architecture Differences

The AMD Radeon Pro W6600M is based on the Navi 23 chip, part of the RDNA 2.0 architecture, in the Radeon Pro Mobile (W6x00M) generation. The NVIDIA CMP 50HX is based on the TU102 chip, part of the Turing architecture, in the Mining GPUs generation. The process nodes are different, 7 nm for AMD versus 12 nm for NVIDIA, both from TSMC. The transistor counts are 11,060 million versus 18,600 million, and die sizes are 237 mm² versus 754 mm², giving AMD a 46.7M per mm² density versus NVIDIA's 24.7M per mm².

The core layouts are distinct. AMD uses 1,792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores. NVIDIA uses 3,584 shading units, 192 TMUs, 80 ROPs, 56 ray tracing cores, and 448 tensor cores. The AMD architecture leverages RDNA 2.0's design to reach a boost clock of 2034 MHz, while the NVIDIA Turing chip boosts to 1545 MHz. The AMD card has no tensor cores listed, while NVIDIA packs 448 of them.

Both cards support the same API levels: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The key feature difference lies in the ray tracing and tensor core counts. The NVIDIA card has twice as many ray tracing cores as the AMD card, 56 versus 28, and it has dedicated tensor cores for AI workloads. The AMD card relies on its RDNA 2.0 architecture without tensor core support. The NVIDIA card is also a mining-specific product with no display outputs, while the AMD card is a mobile Radeon Pro part with portable device dependent outputs. The AMD card's predecessor is FirePro Mobile, while the NVIDIA card has no predecessor listed. Both are marked as end-of-life in the database.
