AMD Radeon Pro WX 7100 vs NVIDIA CMP 50HX Comparison

Where Each One Wins

The NVIDIA CMP 50HX is the clear performance leader in every recorded benchmark test. The data shows it wins both head-to-head comparisons, with a 39.8% advantage in Geekbench OpenCL and a 19.6% advantage in Geekbench Vulkan. The AMD Radeon Pro WX 7100 does not win a single test in the comparison. That said, the two cards occupy entirely different use cases. The CMP 50HX is a mining-focused product with no display outputs, while the WX 7100 is a professional workstation card with 4x DisplayPort 1.4a outputs.

For compute-heavy workloads that rely on OpenCL, the CMP 50HX is the obvious choice. Its average benchmark score is 51,790, which places it in the 86th percentile of all GPUs. The WX 7100 averages 40,063, sitting in the 82nd percentile. The 11,727-point average gap is substantial. The CMP 50HX also has a third benchmark result in its favor on the Vulkan side, where it scores 47,445 versus 39,683 for the AMD card. If your workload is purely computational and you do not need video output, the NVIDIA part dominates.

The WX 7100 wins on practicality for workstation environments. It is a single-slot card with a 130 W TDP and a single 6-pin power connector. The CMP 50HX is dual-slot, requires 250 W, and needs two 8-pin connectors. The AMD card also uses a standard PCIe 3.0 x16 interface, whereas the NVIDIA part uses PCIe 1.0 x4, which is an unusual limitation for a modern card. For anyone building a system that must output to displays, the WX 7100 is the only functional option here, since the CMP 50HX has no display outputs at all.

Architecture Differences

The NVIDIA CMP 50HX is built on the TU102 chip using the Turing architecture on a 12 nm process from TSMC. It packs 18,600 million transistors into a 754 mm² die, giving a transistor density of 24.7 million per square millimeter. The architecture includes 3,584 shading units, 192 texture mapping units, and 80 ROPs. It also features 56 RT cores and 448 tensor cores, which are absent entirely from the AMD part. The memory subsystem uses 10 GB of GDDR6 on a 320-bit bus, delivering 560.0 GB/s of bandwidth. Memory operates at 1750 MHz, translating to 14 Gbps effective.

The AMD Radeon Pro WX 7100 uses the Ellesmere chip with the GCN 4.0 architecture on a 14 nm process from GlobalFoundries. It has 5,700 million transistors on a 232 mm² die, with a transistor density of 24.6 million per square millimeter. The compute configuration includes 2,304 shading units, 144 TMUs, and only 32 ROPs. There are no RT cores or tensor cores. Memory is 8 GB of GDDR5 on a 256-bit bus, with 224.0 GB/s of bandwidth and 7 Gbps effective. The FP32 throughput is 5.728 TFLOPS, while the FP16 throughput is identical at 5.728 TFLOPS because GCN 4.0 processes FP16 at a 1:1 ratio.

The architectural gap is stark. The CMP 50HX has 56% more shading units, 33% more TMUs, and 150% more ROPs. The transistor count is more than 3 times higher. The Turing architecture also supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the GCN 4.0 card is limited to DirectX 12 (12_0) and Vulkan 1.3. Both support OpenGL 4.6. The CMP 50HX also has dedicated RT and tensor cores for ray tracing and AI workloads, which the WX 7100 cannot handle with dedicated hardware.

The clock speeds differ as well. The NVIDIA card has a base clock of 1350 MHz and a boost clock of 1545 MHz. The AMD card runs at 1188 MHz base and 1243 MHz boost. The pixel rate is 123.6 GPixel/s for the CMP 50HX versus 39.78 GPixel/s for the WX 7100. Texture rate is 296.6 GTexel/s versus 179.0 GTexel/s. These raw rates explain the large benchmark deltas, as the NVIDIA card is simply doing more work per clock across every pipeline.

The AMD card has no recorded width.

API support differs as well. The NVIDIA card supports DirectX 12 Ultimate (12_2) and Vulkan 1.4. The AMD card supports DirectX 12 (12_0) and Vulkan 1.3. Both support OpenGL 4.6. The release dates are far apart: the CMP 50HX launched on 2021-06-23, while the WX 7100 launched on 2016-11-09. The AMD card had a launch MSRP of 799 USD. The NVIDIA card has no recorded launch MSRP.

Head-to-Head Benchmarks

The Geekbench OpenCL test shows the largest gap. The NVIDIA CMP 50HX scores 56,135, while the AMD Radeon Pro WX 7100 scores 40,148. That is a 39.8% difference. This is the single biggest win for the NVIDIA card in the recorded data. The 15,987-point raw difference is larger than the entire average benchmark score of many mid-range GPUs. The OpenCL result reflects the raw compute throughput differences, where the NVIDIA card has 11.07 TFLOPS of FP32 performance versus 5.728 TFLOPS for the AMD card.

The Geekbench Vulkan test shows a smaller but still decisive gap. The NVIDIA card scores 47,445 versus 39,683 for the AMD card, a 19.6% difference. This is a 7,762-point gap. Vulkan performance depends more on driver efficiency and architecture overhead, and the Turing architecture's newer design shows a clear advantage here, though not as large as in OpenCL. The NVIDIA card also has a higher peak FP16 rate of 22.15 TFLOPS, which can benefit certain Vulkan compute paths.

The average benchmark scores tell a similar story. The CMP 50HX averages 51,790 across its two tests. The WX 7100 averages 40,063 across its three tests, which include a Geekbench Metal score of 40,357 that has no direct counterpart on the NVIDIA card. The NVIDIA card's average is 29.3% higher, even though it has fewer benchmark results. The percentile ranking also favors NVIDIA: 86th versus 82nd for AMD.

Nearest rival data provides context. The CMP 50HX's average score of 51,790 is 1.6% higher than the AMD Radeon RX 6900 XT's 50,951, and 3.6% higher than the AMD Radeon RX Vega 64's 50,001. The WX 7100's average of 40,063 is 0.6% lower than the AMD Radeon Pro 580's 40,318 and 0.8% lower than the NVIDIA GeForce RTX 5070's 40,377. This means the WX 7100 is competitive with those two cards, but it is firmly below the CMP 50HX's performance class. The CMP 50HX sits closer to high-end gaming cards like the RX 6900 XT, while the WX 7100 sits in a mid-range workstation tier.

The Verdict

The data is unambiguous. The NVIDIA CMP 50HX wins both head-to-head benchmark tests and has a significantly higher average benchmark score. It is 39.8% faster in OpenCL and 19.6% faster in Vulkan. It has more shading units, more memory bandwidth, higher clock speeds, and newer architecture features like RT and tensor cores. It also sits in a higher performance percentile (86th versus 82nd). For any compute workload that does not require a display output, the CMP 50HX is the stronger card by a wide margin.

The AMD Radeon Pro WX 7100 wins on practicality in professional settings. It is single-slot, uses 130 W instead of 250 W, requires only one 6-pin connector, and has 4x DisplayPort 1.4a outputs. It also uses a standard PCIe 3.0 x16 interface, whereas the NVIDIA card's PCIe 1.0 x4 interface is a potential bottleneck for some workloads. The WX 7100 launched at a lower power envelope and has a recorded launch MSRP of 799 USD. It is also from an earlier generation (2016 versus 2021), which explains its lower performance.

For buyers who need raw compute performance in OpenCL or Vulkan and have no need for video output, the CMP 50HX is the clear choice. Its 10 GB GDDR6 memory and 560.0 GB/s bandwidth handle large datasets, and its 11.07 TFLOPS FP32 throughput is nearly double the AMD card's 5.728 TFLOPS. For buyers who need a workstation card with display outputs, professional driver validation, and low power draw, the WX 7100 is the only viable option in this comparison, despite its lower performance. The CMP 50HX cannot output video at all, so it is simply not a workstation replacement.

The verdict depends entirely on the use case. Compute-only workloads favor the NVIDIA card heavily. Display-capable workstation use favors the AMD card by default, because the NVIDIA card has no outputs. There is no scenario where the WX 7100 beats the CMP 50HX on raw performance, and no scenario where the CMP 50HX can substitute for the WX 7100's display capabilities. Choose based on whether you need pixels or pure throughput.
