AMD Radeon Pro WX 7100 vs NVIDIA GeForce RTX 4080 Comparison

Where Each One Wins

The recorded benchmark data paints an extremely lopsided picture between these two GPUs. The NVIDIA GeForce RTX 4080 wins every single head-to-head comparison in the database, with the AMD Radeon Pro WX 7100 failing to secure a single victory in any recorded test.

Looking at the shared tests, the RTX 4080 dominates both compute and graphics workloads. In Geekbench OpenCL, the RTX 4080 scores 214739 against the WX 7100's 40148, a massive 434.9% advantage. The Vulkan gap is even wider: 263779 versus 39683, translating to a 564.7% lead for NVIDIA. These are not marginal wins; the RTX 4080 outperforms the WX 7100 by a factor of roughly five in raw compute throughput.

The RTX 4080 also has a broader benchmark footprint. The database includes ten benchmark entries for the NVIDIA card, covering DirectX 9, 10, 11, 12, OpenCL, Vulkan, 2D, 3D, and compute workloads. The WX 7100 only has three recorded benchmarks, all from Geekbench (Metal, OpenCL, Vulkan). This means the AMD card cannot even be measured in several API-specific tests where the RTX 4080 has data, including Passmark's DirectX suite and 3DMark Steel Nomad.

For use-case segmentation, the RTX 4080 is the clear choice for any workload involving modern graphics APIs, ray tracing, or high-end compute. The WX 7100's only recorded win category is Metal, where it scores 40357, but there is no comparable Metal score for the RTX 4080 in the database, so a direct comparison cannot be made. In every test where both cards have results, NVIDIA wins decisively.

Architecture Differences

The architectural gap between these two GPUs is generational. The RTX 4080 uses the AD103 chip built on Ada Lovelace architecture, fabricated on a 5 nm process at TSMC. The WX 7100 uses the Ellesmere chip based on GCN 4.0 architecture, manufactured on a 14 nm process at GlobalFoundries. This process difference alone explains much of the performance disparity: 5 nm versus 14 nm means the NVIDIA chip packs far more transistors into a smaller area.

The transistor counts tell the story clearly. The RTX 4080 has 45,900 million transistors on a 379 mm² die, yielding a density of 121.1 million transistors per square millimeter. The WX 7100 has 5,700 million transistors on a 232 mm² die, for a density of 24.6 million per square millimeter. That is roughly a five-fold difference in transistor density, which aligns with the five-fold performance gap observed in benchmarks.

The RTX 4080 includes dedicated hardware features that the WX 7100 completely lacks. It has 76 ray tracing cores and 304 tensor cores, while the AMD card lists null for both. This means the NVIDIA card can accelerate ray-traced workloads and AI inference tasks directly in hardware, while the WX 7100 relies entirely on shader-based processing for those workloads.

The memory architectures also differ fundamentally. The RTX 4080 uses 16 GB of GDDR6X memory with a 256-bit bus, delivering 716.8 GB/s of bandwidth. The WX 7100 uses 8 GB of GDDR5 on a 256-bit bus, providing 224.0 GB/s. Both have the same bus width, but the newer memory type and higher effective speed (22.4 Gbps versus 7 Gbps) give NVIDIA a 3.2x bandwidth advantage. The RTX 4080 also doubles the memory capacity, which matters for large datasets and high-resolution textures.

Clock speeds show a similar gap. The RTX 4080 runs at 2205 MHz base and 2505 MHz boost, while the WX 7100 operates at 1188 MHz base and 1243 MHz boost. The NVIDIA card's boost clock is more than double the AMD card's base clock. Combined with 9728 shading units versus 2304, the RTX 4080 has a theoretical FP32 throughput of 48.74 TFLOPS against the WX 7100's 5.728 TFLOPS, an 8.5x difference.

Head-to-Head Benchmarks

The database contains two direct head-to-head benchmark comparisons between these GPUs, and both are decisive NVIDIA victories. In Geekbench OpenCL, the RTX 4080 scores 214739 against the WX 7100's 40148. The delta is 434.9% in favor of NVIDIA. This test measures general-purpose compute performance across a wide range of workloads, and the result reflects the massive architectural advantages of Ada Lovelace over GCN 4.0.

The Vulkan test shows an even larger gap. The RTX 4080 records 263779 points, while the WX 7100 manages 39683. The delta here is 564.7%. Vulkan is a low-overhead graphics and compute API, and the superior shader throughput, memory bandwidth, and driver optimization of the RTX 4080 all contribute to this outcome.

Beyond these shared tests, the RTX 4080 has additional benchmark data that the WX 7100 lacks. In 3DMark Steel Nomad DX12, the RTX 4080 scores 6567. In Passmark tests, it records 204 in DirectX 10, 314 in DirectX 11, 132 in DirectX 12, 370 in DirectX 9, 1239 in 2D, 34457 in 3D, and 20671 in GPU compute. The WX 7100 has no corresponding data for any of these tests, so no direct comparison is possible. However, the WX 7100 does have a Geekbench Metal score of 40357, which is its highest recorded result. There is no Metal score for the RTX 4080 in the database, so this remains the AMD card's only unopposed data point.

The average benchmark scores reflect the overall picture. The RTX 4080 has an average score of 54247 across its ten benchmarks, placing it in the 86th percentile of all GPUs. The WX 7100 has an average of 40063 across its three benchmarks, putting it in the 82nd percentile. Despite the massive performance gap in shared tests, the percentile difference is relatively small because the WX 7100's average is boosted by its Metal score and the RTX 4080's average is pulled down by low Passmark API-specific scores.

The Verdict

The data leaves no room for ambiguity. The NVIDIA GeForce RTX 4080 is categorically superior to the AMD Radeon Pro WX 7100 in every recorded benchmark where both cards have results. The smallest advantage is 434.9% in OpenCL, and the largest is 564.7% in Vulkan. These are not incremental improvements; they represent different performance classes entirely.

For users choosing between these two cards, the decision depends on what they prioritize. The RTX 4080 is the only choice for anyone who needs ray tracing, tensor core acceleration, high-bandwidth GDDR6X memory, or modern API support like DirectX 12 Ultimate and Vulkan 1.4. It also offers double the memory capacity at 16 GB, which is critical for large datasets, high-resolution textures, and AI workloads.

The WX 7100 does have advantages in specific areas, though they are not reflected in the shared benchmarks. It has a much lower TDP at 130 W versus 320 W, a single-slot design versus triple-slot, and a smaller physical footprint (241 mm versus 310 mm length). It also requires only a 300 W PSU versus 700 W. For constrained environments where power and space are limiting factors, the WX 7100 is the more practical option. Its launch MSRP was 799 USD, compared to 1,199 USD for the RTX 4080.

The nearest rival data provides context for how each card sits in the broader market. The RTX 4080's closest competitor is the RTX 4080 SUPER, which scores 54209, just 0.1% lower. The AMD Radeon Pro W5700X scores 54828, which is 1.1% higher. The WX 7100's nearest rivals include the AMD Radeon Pro 580 at 40318 (0.6% lower), the NVIDIA GeForce RTX 5070 at 40377 (0.8% lower), and the NVIDIA RTX A500 Mobile at 39568 (1.3% higher).

The verdict is straightforward: the RTX 4080 is the superior performer by every measurable metric in the database. The WX 7100 remains a viable option only for specific use cases involving tight power budgets, single-slot installations, or Metal-only workflows. For anyone prioritizing compute performance, graphics fidelity, or future-proofing, the RTX 4080 is the definitive choice. The data shows a generational leap that the WX 7100 simply cannot bridge.
