AMD Radeon Pro WX 9100 vs NVIDIA CMP 50HX Comparison

Head-to-Head Benchmarks

The recorded data shows a clear sweep for the AMD Radeon Pro WX 9100 across the two shared benchmark tests. In Geekbench OpenCL, the AMD part scores 66,605 against the NVIDIA CMP 50HX's 56,135, an 18.7% advantage. The Vulkan result follows the same pattern: 54,711 for the AMD card versus 47,445 for the NVIDIA card, a 15.3% gap. Neither benchmark falls within a margin that could be considered a statistical tie; the AMD card leads by a meaningful margin in both compute and graphics API workloads.

The average benchmark score reinforces this picture. The AMD Radeon Pro WX 9100 holds an average of 64,212 across all recorded tests, while the NVIDIA CMP 50HX averages 51,790. That is a substantial overall gap of roughly 24% when comparing the aggregate figures. However, the context matters: the AMD card has three recorded benchmark entries (Geekbench Metal, OpenCL, and Vulkan), while the NVIDIA card only has two (OpenCL and Vulkan). The AMD card's Geekbench Metal score of 71,319 is its strongest result and pulls its average upward, whereas the NVIDIA card's highest recorded score is its OpenCL result of 56,135.

Looking at the nearest rivals in the database provides additional context for each card's standing. The AMD Radeon Pro WX 9100 sits just 0.6% above the NVIDIA CMP 30HX and the AMD Radeon RX 9060 XT LP in average score, and 0.7% above the AMD Radeon RX 7600M. These are tight margins, suggesting the WX 9100 is clustered with a group of cards that perform at a similar level. The NVIDIA CMP 50HX, by contrast, is 1.6% ahead of the AMD Radeon RX 6900 XT, 3.6% ahead of the AMD Radeon RX Vega 64, and 4.1% ahead of the Intel Arc A550M in average score. The CMP 50HX leads its nearest rivals by a wider margin than the WX 9100 leads its own, but the absolute scores for the CMP 50HX's rivals are lower, reflecting its weaker overall position.

The percentile rankings tell a similar story. The AMD Radeon Pro WX 9100 sits at the 89th percentile among all GPUs in the database, while the NVIDIA CMP 50HX sits at the 86th percentile. That three-point gap in percentile placement aligns with the benchmark deltas: the AMD card is the stronger performer in head-to-head testing, and the database's overall ranking reflects that advantage.

Architecture Differences

The two cards come from different manufacturing nodes and foundries. The AMD Radeon Pro WX 9100 uses a Vega 10 chip built on a 14 nm process at GlobalFoundries, while the NVIDIA CMP 50HX uses a TU102 chip built on a 12 nm process at TSMC. The AMD chip integrates 12,500 million transistors on a 495 mm² die, giving a transistor density of 25.3 million per square millimeter. The NVIDIA chip packs 18,600 million transistors onto a 754 mm² die, resulting in a slightly lower density of 24.7 million per square millimeter. The NVIDIA chip is physically larger and houses more transistors, but the AMD chip achieves a modestly higher packing density.

Architecture generations differ as well. The AMD card belongs to the GCN 5.0 architecture under the Radeon Pro Polaris (WX x100) generation. The NVIDIA card uses the Turing architecture under a Mining GPUs generation. These design philosophies diverge significantly in feature set. The NVIDIA CMP 50HX includes 56 ray tracing cores and 448 tensor cores, hardware that the AMD Radeon Pro WX 9100 lacks entirely. The AMD card has no equivalent dedicated acceleration blocks for ray tracing or tensor operations. This is a notable architectural split: the NVIDIA card is built with Turing's specialized cores, even though it is marketed for mining rather than graphics workloads.

Compute resource allocation also differs. The AMD card carries 4,096 shading units, 256 texture mapping units, and 64 render output units. The NVIDIA card has 3,584 shading units, 192 TMUs, and 80 ROPs. The AMD card therefore has more shading units and TMUs, while the NVIDIA card has more ROPs. These differences show up in the theoretical throughput figures: the AMD card reaches 12.29 TFLOPS FP32 and 24.58 TFLOPS FP16 (at a 2:1 ratio), while the NVIDIA card reaches 11.07 TFLOPS FP32 and 22.15 TFLOPS FP16 (also at 2:1). The AMD card's pixel rate is 96.00 GPixel/s versus 123.6 GPixel/s for the NVIDIA card, but the AMD card's texture rate of 384.0 GTexel/s exceeds the NVIDIA card's 296.6 GTexel/s. The ROP advantage for NVIDIA and the TMU advantage for AMD are clearly reflected in these rates.

Memory architecture is another major divergence. The AMD Radeon Pro WX 9100 uses 16 GB of HBM2 with a 2048-bit bus and 483.8 GB/s of bandwidth. The NVIDIA CMP 50HX uses 10 GB of GDDR6 with a 320-bit bus and 560.0 GB/s of bandwidth. The NVIDIA card has higher raw bandwidth despite a narrower bus, but the AMD card has 60% more memory capacity. The AMD card's memory clock is listed at 945 MHz (1890 Mbps effective), while the NVIDIA card runs at 1750 MHz (14 Gbps effective). The effective data rates differ substantially, and the NVIDIA card's GDDR6 implementation delivers the higher bandwidth figure.

Interface and output configurations differ sharply. The AMD card uses PCIe 3.0 x16 and provides 6x mini-DisplayPort 1.4a outputs. The NVIDIA card uses PCIe 1.0 x4 and has no display outputs at all, a design choice consistent with its mining-focused purpose. The NVIDIA card's PCIe interface is dramatically narrower, which limits host communication bandwidth but is sufficient for mining workloads. The AMD card's full x16 interface and display outputs make it a functional workstation graphics card.

The Verdict

The data points to a straightforward conclusion: the AMD Radeon Pro WX 9100 is the stronger performer in every recorded head-to-head test. It wins both shared benchmarks, holds a higher average score, and ranks higher in the database's overall percentile placement. For any workload measured by Geekbench OpenCL or Vulkan, the AMD card is the better choice based on the recorded results.

The NVIDIA CMP 50HX does have architectural features that the AMD card lacks, specifically ray tracing cores and tensor cores. However, the benchmark data does not show these features translating into higher scores on the tests recorded in the database. The NVIDIA card also has higher memory bandwidth (560.0 GB/s versus 483.8 GB/s) and a higher pixel rate (123.6 GPixel/s versus 96.00 GPixel/s), but these advantages do not overcome the AMD card's lead in the actual benchmark results.

For users who need display outputs, the choice is unambiguous: the AMD card provides 6x mini-DisplayPort 1.4a connections, while the NVIDIA card has none. For users who need a PCIe 3.0 x16 interface, the AMD card offers it, while the NVIDIA card is limited to PCIe 1.0 x4. The AMD card is also more power-efficient in the sense that it achieves higher benchmark scores with a lower TDP of 230 W versus 250 W for the NVIDIA card. The AMD card's suggested PSU is 550 W, while the NVIDIA card's is 600 W.

The production status for both cards is end-of-life, so neither is a current-generation product. The AMD card's launch MSRP was 1,599 USD. The NVIDIA card has no recorded launch MSRP in the database.

Where Each One Wins

The AMD Radeon Pro WX 9100 wins in every recorded benchmark category. In Geekbench OpenCL, it leads by 18.7%. In Geekbench Vulkan, it leads by 15.3%. Its average benchmark score of 64,212 is higher than the NVIDIA card's 51,790, and it also has a third benchmark entry (Geekbench Metal) where it scores 71,319, a result the NVIDIA card cannot match because it has no Metal score recorded. The AMD card also wins on memory capacity with 16 GB versus 10 GB, and on shading units with 4,096 versus 3,584.

The NVIDIA CMP 50HX wins in several specification categories that do not translate into benchmark victories. Its memory bandwidth of 560.0 GB/s exceeds the AMD card's 483.8 GB/s. Its pixel rate of 123.6 GPixel/s is higher than the AMD card's 96.00 GPixel/s. It has more ROPs (80 versus 64), and it includes 56 ray tracing cores and 448 tensor cores that the AMD card lacks entirely. Its die is larger at 754 mm² versus 495 mm², and it packs more transistors at 18,600 million versus 12,500 million. The NVIDIA card also supports DirectX 12 Ultimate (12_2), while the AMD card supports DirectX 12 (12_1). For Vulkan, the NVIDIA card supports version 1.4, while the AMD card supports 1.3. These specification advantages are real, but the benchmark data shows they do not produce higher scores in the recorded tests.
