AMD Radeon Pro WX 9100 vs NVIDIA GeForce RTX 4080 SUPER Comparison

The Verdict

The benchmark database presents a clear generational divide between these two cards. The AMD Radeon Pro WX 9100, released in 2017, is a workstation-focused GPU built on the older GCN 5.0 architecture. The NVIDIA GeForce RTX 4080 SUPER, released in 2024, is a consumer-grade powerhouse using the Ada Lovelace architecture. Based on the recorded head-to-head data, the RTX 4080 SUPER wins both shared benchmarks decisively. In Geekbench OpenCL, the NVIDIA card scores 219065 against the AMD card's 66605, a delta of -69.6 percent. In Geekbench Vulkan, the NVIDIA card scores 260075 against 54711, a delta of -79 percent.

The data suggests that anyone seeking maximum compute performance in OpenCL or Vulkan workloads should pick the RTX 4080 SUPER without hesitation. The Radeon Pro WX 9100, while end-of-life and significantly older, still holds a place in the database with an average benchmark score of 64212 and a percentile ranking of 89 versus all GPUs. The RTX 4080 SUPER has a lower percentile ranking at 86, but its average score of 54209 is dragged down by including a wide range of Passmark tests, including older DirectX 9 and DirectX 10 results. The verdict from the data is simple: for raw modern compute throughput, the RTX 4080 SUPER is the superior choice. The Radeon Pro WX 9100 is only relevant for legacy compatibility or niche workstation tasks where its specific feature set, like six mini-DisplayPort outputs, is required.

Architecture Differences

The architectural gap between these two GPUs is enormous. The AMD Radeon Pro WX 9100 uses the Vega 10 chip on a 14 nm process from GlobalFoundries. It packs 12,500 million transistors on a 495 mm² die, resulting in a transistor density of 25.3 million per square millimeter. The NVIDIA GeForce RTX 4080 SUPER uses the AD103 chip on a 5 nm process from TSMC. It contains 45,900 million transistors on a smaller 379 mm² die, achieving a density of 121.1 million per square millimeter. This density difference, roughly 4.8 times higher for the NVIDIA chip, is a direct result of the newer manufacturing node.

The Radeon Pro WX 9100 features 4096 shading units, 256 texture mapping units, and 64 raster output pipelines. It has no dedicated ray tracing or tensor cores. The RTX 4080 SUPER has 10240 shading units, 320 TMUs, and 112 ROPs. It also includes 80 ray tracing cores and 320 tensor cores. The NVIDIA card supports DirectX 12 Ultimate (12_2) while the AMD card only supports DirectX 12 (12_1). Both support OpenGL 4.6, but the NVIDIA card supports Vulkan 1.4 while the AMD card supports Vulkan 1.3. The memory subsystems also differ fundamentally. The AMD card uses 16 GB of HBM2 on a 2048-bit bus, achieving 483.8 GB/s of bandwidth. The NVIDIA card uses 16 GB of GDDR6X on a 256-bit bus, achieving 736.3 GB/s. The NVIDIA memory interface is narrower but much faster per pin.

Clock speeds show the process advantage. The AMD card has a base clock of 1200 MHz and a boost clock of 1500 MHz. The NVIDIA card has a base clock of 2295 MHz and a boost clock of 2550 MHz. This higher clock speed, combined with more shading units, explains the massive compute gap. The AMD card delivers 12.29 TFLOPS of FP32 performance, while the NVIDIA card delivers 52.22 TFLOPS. For FP16, the AMD card achieves 24.58 TFLOPS using a 2:1 ratio, while the NVIDIA card achieves 52.22 TFLOPS at a 1:1 ratio. The pixel and texture rates tell the same story: 96.00 GPixel/s and 384.0 GTexel/s for AMD versus 285.6 GPixel/s and 816.0 GTexel/s for NVIDIA.

Head-to-Head Benchmarks

The database contains two direct comparisons between these GPUs, and the results are lopsided. In Geekbench OpenCL, the RTX 4080 SUPER scores 219065 while the Radeon Pro WX 9100 scores 66605. This represents a 69.6 percent deficit for the AMD card. The OpenCL test is a general-purpose compute benchmark, so this gap reflects the sheer difference in raw processing power. The RTX 4080 SUPER has more than double the shading units, nearly double the boost clock, and more than four times the FP32 throughput.

In Geekbench Vulkan, the margin widens further. The RTX 4080 SUPER scores 260075 while the Radeon Pro WX 9100 scores 54711, a delta of -79 percent. Vulkan is a low-level graphics API that benefits from efficient driver overhead and modern hardware features. The NVIDIA card's Ada Lovelace architecture, with its dedicated ray tracing and tensor cores, clearly handles this workload more effectively. The AMD card, based on the older GCN 5.0 design, falls far behind.

The database records zero wins for the AMD card and two wins for the NVIDIA card in this head-to-head comparison. The nearest rivals for the Radeon Pro WX 9100 provide context for its performance level. Its average score of 64212 is only 0.6 percent ahead of the NVIDIA CMP 30HX and the AMD Radeon RX 9060 XT LP, and 0.7 percent ahead of the AMD Radeon RX 7600M. The RTX 4080 SUPER, by contrast, sits within 0.1 percent of the NVIDIA GeForce RTX 4080 and trails the AMD Radeon Pro W5700X by 1.1 percent. This places the RTX 4080 SUPER in a much higher performance tier.

FAQ

Q: Which card has a higher average benchmark score?

A: The AMD Radeon Pro WX 9100 has an average benchmark score of 64212, while the NVIDIA GeForce RTX 4080 SUPER has an average score of 54209.

A: The AMD Radeon Pro WX 9100 has a transistor density of 25.3 million per square millimeter on a 495 mm² die. The NVIDIA GeForce RTX 4080 SUPER has a density of 121.1 million per square millimeter on a 379 mm² die, which is roughly 4.8 times denser.

Q: How do the power requirements compare?

A: The AMD Radeon Pro WX 9100 has a TDP of 230 W and requires a 550 W suggested power supply. The NVIDIA GeForce RTX 4080 SUPER has a TDP of 320 W and requires a 700 W suggested power supply. The NVIDIA card uses a single 16-pin connector, while the AMD card uses one 6-pin and one 8-pin connector.

Q: Which card has more shading units?

A: The NVIDIA GeForce RTX 4080 SUPER has 10240 shading units, while the AMD Radeon Pro WX 9100 has 4096. This is a 2.5 times difference in favor of the NVIDIA card.

Where Each One Wins

The NVIDIA GeForce RTX 4080 SUPER wins in every benchmark category where both cards have recorded scores. In OpenCL compute, it is 69.6 percent faster. In Vulkan graphics, it is 79 percent faster. This makes it the clear choice for any modern workload involving compute shaders, machine learning inference, or high-resolution gaming. Its 52.22 TFLOPS of FP32 performance and 52.22 TFLOPS of FP16 performance at a 1:1 ratio make it suitable for AI-adjacent tasks. The 80 ray tracing cores and 320 tensor cores add hardware acceleration for ray-traced rendering and DLSS-style features, though the database does not include specific tests for these.

The AMD Radeon Pro WX 9100 has no wins in the recorded head-to-head data. Its strengths lie elsewhere. It has six mini-DisplayPort 1.4a outputs, which is a higher count than the RTX 4080 SUPER's single HDMI 2.1 and three DisplayPort 1.4a outputs. This makes the AMD card potentially more useful in multi-monitor workstation configurations. Its HBM2 memory, while slower in bandwidth, occupies a 2048-bit bus, which may offer different latency characteristics. The card is also physically smaller at 267 mm in length and 111 mm in height, compared to the NVIDIA card's 310 mm length, 140 mm height, and 61 mm width. The AMD card is dual-slot, while the NVIDIA card is triple-slot.

For legacy software that relies on older GCN-optimized code paths, the Radeon Pro WX 9100 might still function adequately. Its production status is end-of-life, as is the RTX 4080 SUPER, but the AMD card's release in 2017 means it has a longer history of driver maturation for professional applications. The RTX 4080 SUPER, released in 2024, is newer and benefits from more recent architectural features. The data does not support any scenario where the AMD card outperforms the NVIDIA card in raw compute, so the use-case split is clear: the RTX 4080 SUPER for performance, the Radeon Pro WX 9100 for specific display output requirements or legacy compatibility.
