The Verdict

The data paints a clear picture for different audiences. The NVIDIA GeForce RTX 4080 is the choice for anyone prioritizing raw compute and modern API performance. Its Geekbench OpenCL score of 214,739 and Vulkan score of 263,779 are decisive wins, and it offers a 1:1 FP16 ratio, 76 RT cores, and 304 tensor cores for workloads that leverage those features. The RTX 4080 also carries a lower launch MSRP of 1,199 USD compared to the WX 9100's 1,599 USD.

The AMD Radeon Pro WX 9100, however, holds its own in the average benchmark standings. Its 64,212 average score exceeds the RTX 4080's 54,247, and it ranks at the 89th percentile versus the 86th percentile for NVIDIA. This suggests that in the specific tests the database runs for the WX 9100, the older AMD card performs surprisingly well, likely due to its massive 2048-bit HBM2 memory bus and workstation-oriented design.

For workstation users running legacy OpenCL workloads, the WX 9100's 483.8 GB/s of bandwidth and 16 GB of HBM2 may still be relevant, but the RTX 4080's newer architecture and higher transistor density (121.1M per mm² versus 25.3M per mm²) make it the more future-proof option. The RTX 4080 is end-of-life, as is the WX 9100, so neither is a new purchase, but the NVIDIA card offers significantly more compute headroom for modern applications.

Head-to-Head Benchmarks

The head-to-head data in the database covers two tests, and the NVIDIA GeForce RTX 4080 wins both decisively.

In Geekbench OpenCL, the RTX 4080 scores 214,739 against the WX 9100's 66,605. The delta is 69% in NVIDIA's favor. This is a massive gap that reflects the generational leap between the 2017-era Vega 10 chip and the 2022 AD103 silicon. The RTX 4080's 48.74 TFLOPS of FP32 compute dwarfs the WX 9100's 12.29 TFLOPS, and its 9728 shading units provide more than double the parallel processing capacity.

Geekbench Vulkan shows an even wider margin. The RTX 4080 hits 263,779, while the WX 9100 manages 54,711, a 79.3% difference. Vulkan performance often scales with driver optimization and hardware features, and the Ada Lovelace architecture's dedicated RT cores and tensor cores likely contribute to this result. The WX 9100's Vulkan score is respectable for its era, but it cannot compete with NVIDIA's modern implementation.

The winsA count is 0 and winsB is 2, leaving no ambiguity about which card performs better in these shared benchmarks. However, the average benchmark scores tell a different story: the WX 9100's 64,212 average is notably higher than the RTX 4080's 54,247. This occurs because the database uses different benchmark suites for each card; the WX 9100 is tested on Geekbench Metal, OpenCL, and Vulkan, while the RTX 4080 includes PassMark tests and 3DMark, which pull its average down.

Specification Differences

The two cards differ substantially in nearly every specification category.

The WX 9100 uses a 14 nm process node from GlobalFoundries, while the RTX 4080 uses a 5 nm node from TSMC. The transistor counts reflect this: 12,500 million for AMD versus 45,900 million for NVIDIA. Die size favors AMD in area at 495 mm² versus 379 mm², but transistor density is overwhelmingly in NVIDIA's favor at 121.1M per mm² compared to 25.3M per mm².

Clock speeds show the RTX 4080 running much higher: 2205 MHz base and 2505 MHz boost, versus 1200 MHz base and 1500 MHz boost for the WX 9100. Memory clocks differ too, with the WX 9100 at 945 MHz (1890 Mbps effective) and the RTX 4080 at 1400 MHz (22.4 Gbps effective).

Memory type and bus width are major differentiators. The WX 9100 uses HBM2 with a 2048-bit bus and 483.8 GB/s bandwidth. The RTX 4080 uses GDDR6X with a 256-bit bus but achieves 716.8 GB/s bandwidth. The AMD card's wider bus is its key advantage, though the NVIDIA card's faster memory technology wins on throughput.

Shading units number 4096 for AMD versus 9728 for NVIDIA. TMUs are 256 versus 304, and ROPs are 64 versus 112. Pixel rate is 96.00 GPixel/s for the WX 9100 versus 280.6 GPixel/s for the RTX 4080. Texture rate is 384.0 GTexel/s versus 761.5 GTexel/s.

FP32 compute is 12.29 TFLOPS for AMD versus 48.74 TFLOPS for NVIDIA. FP16 differs in ratio: the WX 9100 offers 24.58 TFLOPS at a 2:1 ratio, while the RTX 4080 offers 48.74 TFLOPS at 1:1, meaning full-rate FP16 on NVIDIA.

The WX 9100 draws 230 W TDP with a dual-slot design and 1x 6-pin plus 1x 8-pin connectors, needing a 550 W PSU. The RTX 4080 uses 320 W, is triple-slot, has a single 16-pin connector, and requires a 700 W PSU. Physical dimensions differ: the WX 9100 is 267 mm long and 111 mm tall, while the RTX 4080 is 310 mm long, 140 mm tall, and 61 mm wide.

Bus interfaces are PCIe 3.0 x16 for AMD versus PCIe 4.0 x16 for NVIDIA. Display outputs are 6x mini-DisplayPort 1.4a on the WX 9100 versus 1x HDMI 2.1 and 3x DisplayPort 1.4a on the RTX 4080.

Architecture Differences

The AMD Radeon Pro WX 9100 is built on the Vega 10 chip using the GCN 5.0 architecture, part of the Radeon Pro Polaris generation. It has no RT cores and no tensor cores, relying purely on traditional shading units for compute. The 14 nm process from GlobalFoundries was state-of-the-art in 2017 but is now several generations old.

The NVIDIA GeForce RTX 4080 uses the AD103 chip with the Ada Lovelace architecture, part of the GeForce 40-series. It includes 76 RT cores and 304 tensor cores, enabling hardware-accelerated ray tracing and AI-based workloads. The 5 nm TSMC process offers significantly better density and efficiency potential.

The WX 9100's GCN architecture was designed for workstation compute, with its 2048-bit HBM2 interface providing massive memory bandwidth for large datasets. The RTX 4080's Ada Lovelace architecture focuses on a balance of rasterization, ray tracing, and compute, with a 256-bit GDDR6X interface that still achieves higher bandwidth due to faster memory clocks.

DirectX support differs: the WX 9100 supports DirectX 12 (12_1), while the RTX 4080 supports DirectX 12 Ultimate (12_2). Vulkan versions also differ, with 1.3 for AMD and 1.4 for NVIDIA. OpenGL support is the same at 4.6.

The transistor density gap is stark: 25.3M per mm² for AMD versus 121.1M per mm² for NVIDIA. This reflects the process node advantage and the architectural efficiency of Ada Lovelace. The WX 9100's larger die size (495 mm²) with fewer transistors suggests a less dense design, while the RTX 4080 packs far more transistors into a smaller area.

FP16 capability highlights another architectural split. The WX 9100 achieves 24.58 TFLOPS FP16 at a 2:1 ratio, meaning it runs FP16 at half the rate of FP32. The RTX 4080 achieves 48.74 TFLOPS FP16 at 1:1, offering full-rate FP16 compute, which is critical for machine learning and certain scientific workloads.

Where Each One Wins

The NVIDIA GeForce RTX 4080 wins in all shared benchmark tests, making it the clear choice for performance-heavy tasks. Its 69% lead in OpenCL and 79.3% lead in Vulkan indicate superior raw compute power. The 48.74 TFLOPS FP32 and FP16 performance, along with 76 RT cores and 304 tensor cores, make it suitable for modern gaming, ray tracing, AI inference, and content creation. Its 716.8 GB/s memory bandwidth and higher clock speeds (2505 MHz boost) support demanding real-time workloads. The DirectX 12 Ultimate support and Vulkan 1.4 ensure compatibility with the latest APIs.

The AMD Radeon Pro WX 9100 wins in average benchmark score, with 64,212 versus 54,247, and holds a higher percentile ranking at 89 versus 86. This suggests its benchmark suite, which includes Geekbench Metal (score of 71,319), showcases strengths that the RTX 4080's tests do not capture. The 2048-bit HBM2 memory bus provides 483.8 GB/s bandwidth, which can be advantageous for memory-bandwidth-bound workloads. Its lower TDP of 230 W and dual-slot design make it easier to integrate into dense workstation builds. The 6x mini-DisplayPort 1.4a outputs support multi-monitor professional setups. For legacy OpenCL applications or environments where the GCN architecture is optimized, the WX 9100 may still deliver adequate performance.

The RTX 4080's lower launch MSRP of 1,199 USD versus 1,599 USD for the WX 9100 is notable, though both cards are end-of-life. The NVIDIA card offers more future-proofing through its newer architecture and higher compute ceiling. The WX 9100's edge in average score and percentile is interesting but does not translate to wins in the direct head-to-head tests, indicating that its benchmark set is more favorable to its design. Users should consider their specific workload: the RTX 4080 for modern, compute-heavy tasks, and the WX 9100 for bandwidth-sensitive or legacy workstation applications.
