AMD Radeon Pro WX 9100 vs NVIDIA RTX 5880 Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data contains a single direct comparison between these two workstation cards, and the result is decisive. In the Geekbench OpenCL test, the NVIDIA RTX 5880 Ada Generation scored 326,898, while the AMD Radeon Pro WX 9100 managed 66,605. This represents a 79.6% advantage for NVIDIA in this specific workload, meaning the RTX 5880 delivers roughly five times the raw compute throughput of the older AMD card. The magnitude of this delta is substantial enough to define the entire competitive landscape between these products.

The AMD Radeon Pro WX 9100, despite being the older architecture, still holds its own in the broader database context. Its average benchmark score of 64,212 places it in the 89th percentile of all GPUs tracked, which is notably higher than the RTX 5880's 85th percentile ranking despite the latter's far superior raw scores. This discrepancy stems from the different benchmark suites each card has been subjected to, with the AMD card having results in Metal, OpenCL, and Vulkan, while the NVIDIA card has a broader range of Passmark tests that pull its average down. The RTX 5880's average score of 45,972 is dragged lower by its Passmark DirectX results, particularly the DirectX 12 score of just 70 and the DirectX 10 score of 167, which are likely testing scenarios that do not reflect the card's workstation strengths.

Looking at the nearest rivals in the database, the AMD Radeon Pro WX 9100 sits just 0.6% above the NVIDIA CMP 30HX and the AMD Radeon RX 9060 XT LP, with a 0.7% edge over the AMD Radeon RX 7600M and 0.8% over the AMD Radeon Pro Vega 56. These are all very tightly clustered scores, indicating that the WX 9100's performance profile is well understood and firmly established within a narrow band. The NVIDIA RTX 5880 Ada Generation, by contrast, has nearest rivals including the NVIDIA RTX A2000 at a 0.2% deficit, the Intel Arc A730M at 0.8% behind, and the AMD Radeon Pro 5500 XT at 1.3% behind, while the AMD Radeon RX 5600M sits 1.4% ahead. This clustering suggests the RTX 5880's average score is less representative of its peak capability, given the wide variance between its OpenCL result and its Passmark scores.

Architecture Differences

The fundamental architectural gap between these two cards is generational and profound. The AMD Radeon Pro WX 9100 utilizes the Vega 10 chip built on GCN 5.0 architecture, manufactured on a 14 nm process at GlobalFoundries. This chip contains 12,500 million transistors on a 495 mm² die, yielding a transistor density of 25.3 million per square millimeter. The NVIDIA RTX 5880 Ada Generation employs the AD102 chip with Ada Lovelace architecture, fabricated on a 5 nm process at TSMC, packing 76,300 million transistors into a 609 mm² die for a density of 125.3 million per square millimeter. The density difference is nearly fivefold, reflecting the massive process node advantage NVIDIA holds.

The compute resources differ by an order of magnitude. The AMD card offers 4,096 shading units, 256 texture mapping units, and 64 render output units. The NVIDIA card counters with 14,080 shading units, 440 TMUs, and 176 ROPs. More critically, the RTX 5880 includes 110 dedicated ray tracing cores and 440 tensor cores, features entirely absent from the AMD architecture. These specialized units enable hardware-accelerated ray tracing and AI-assisted workloads that the WX 9100 cannot accelerate at all. The pixel rate tells the story: 96.00 GPixel/s for AMD versus 433.0 GPixel/s for NVIDIA, and the texture rate of 384.0 GTexel/s versus 1,082.4 GTexel/s reinforces the same conclusion.

Clock behavior also diverges sharply. The AMD card runs at a 1200 MHz base and 1500 MHz boost, while the NVIDIA card has a lower 975 MHz base but a much higher 2460 MHz boost. This indicates the NVIDIA card is designed to sustain high boost clocks under load, whereas the AMD card operates within a tighter frequency envelope. Floating-point performance scales accordingly: the WX 9100 delivers 12.29 TFLOPS FP32 and 24.58 TFLOPS FP16 with a 2:1 ratio, while the RTX 5880 achieves 69.27 TFLOPS for both FP32 and FP16 with a 1:1 ratio, meaning no throughput penalty for reduced precision.

Where Each One Wins

The data supports a clear split: the NVIDIA RTX 5880 Ada Generation wins decisively in compute-heavy OpenCL workloads, while the AMD Radeon Pro WX 9100 demonstrates broader benchmark coverage across multiple API families. The WX 9100 has recorded scores in Geekbench Metal (71,319), OpenCL (66,605), and Vulkan (54,711), showing respectable performance across three different rendering APIs. The RTX 5880, with its single OpenCL score of 326,898, dominates that specific metric but has no comparable Metal or Vulkan results in the database, limiting direct cross-API comparisons.

For users whose work involves OpenCL-accelerated compute, the RTX 5880 is categorically superior, outperforming the WX 9100 by 79.6% in that test. This makes it the clear choice for general-purpose GPU computing, scientific simulation, and data-parallel workloads that leverage OpenCL. The RTX 5880 also benefits from its tensor cores, which enable AI inference and training acceleration that the WX 9100 physically cannot perform, though no benchmark in the data directly quantifies this advantage.

The AMD card's strengths lie in its balanced performance across multiple APIs and its higher percentile ranking of 89 versus 85. For legacy applications that rely on Metal or Vulkan, the WX 9100 has verified performance data, whereas the RTX 5880 lacks such records entirely. The WX 9100 also wins on memory capacity per dollar of power draw in relative terms, though the database does not provide a direct efficiency metric. The 16 GB of HBM2 memory on the AMD card, while smaller than the RTX 5880's 48 GB, operates across a 2048-bit bus with 483.8 GB/s bandwidth, whereas the NVIDIA card uses a 384-bit GDDR6 bus at 864.0 GB/s.

The Verdict

The data makes the choice straightforward for compute-intensive workloads: the NVIDIA RTX 5880 Ada Generation is the superior performer, delivering 79.6% higher OpenCL scores than the AMD Radeon Pro WX 9100. Its 69.27 TFLOPS FP32 performance dwarfs the 12.29 TFLOPS of the AMD card, and its 48 GB memory capacity is three times larger. For professionals running OpenCL-accelerated simulation, rendering, or AI workloads, the RTX 5880 is the only rational pick, provided their systems can accommodate its 285 W TDP and 600 W power supply recommendation.

However, the AMD Radeon Pro WX 9100 retains relevance for specific scenarios. Its higher 89th percentile ranking versus 85th suggests it performs more consistently across the benchmarks it has been tested in, with verified Metal and Vulkan results that the RTX 5880 lacks entirely. The 16 GB of HBM2 memory with a 2048-bit bus may be preferable for certain bandwidth-sensitive legacy applications, and its 230 W TDP makes it easier to integrate into existing power envelopes. The six mini-DisplayPort outputs versus four on the NVIDIA card also give it an edge for multi-display configurations.

Users who require ray tracing, tensor core acceleration, or maximal compute throughput should choose the NVIDIA RTX 5880 Ada Generation without hesitation. Users with legacy OpenCL or Metal dependencies, constrained power budgets, or extensive multi-monitor setups may find the AMD Radeon Pro WX 9100 sufficient, though they must accept its end-of-life status and significantly lower peak performance. The recorded data shows one decisive winner in compute, but the AMD card's broader API coverage and higher percentile rank mean it is not obsolete for all purposes.
