AMD Radeon PRO W7400 vs NVIDIA GeForce RTX 4080 Mobile Comparison

The Verdict

The database comparison between the AMD Radeon PRO W7400 and the NVIDIA GeForce RTX 4080 Mobile shows two fundamentally different products aimed at different workloads. The RTX 4080 Mobile is the clear performance leader, sitting at the 81st percentile of all GPUs in the database, while the W7400 sits at the 50th percentile. The RTX 4080 Mobile delivers 24.72 TFLOPS of FP32 compute versus 7.885 TFLOPS for the W7400, and its 432.0 GB/s memory bandwidth dwarfs the W7400's 172.8 GB/s. The RTX 4080 Mobile also carries 12 GB of GDDR6 memory compared to 8 GB on the W7400.

The W7400 is a single-slot, 55 W professional workstation card with four DisplayPort 2.1 outputs. It is designed for dense multi-display deployments where low power draw and compact physical footprint matter more than raw throughput. The RTX 4080 Mobile is an integrated graphics processor for laptops, consuming 110 W and relying on the portable device for its display outputs. Users who need maximum compute throughput, ray tracing, or tensor core acceleration should choose the RTX 4080 Mobile. Users who need a low-profile, low-power workstation card with multiple modern display outputs should choose the W7400.

The RTX 4080 Mobile's benchmark results confirm its dominance. It scores 159575 in Geekbench OpenCL, 145807 in Geekbench Vulkan, and 24926 in Passmark G3D. The W7400 has no recorded benchmark scores in the database, making direct numerical comparison impossible. The RTX 4080 Mobile's average benchmark score of 38135 places it within 1.3% of the NVIDIA GeForce RTX 4070 and Tesla P4, and it essentially matches the MX570 and RTX 5080 Mobile, with deltas of -0.4% and -0.6% respectively.

Head-to-Head Benchmarks

The head-to-head benchmark data contains no recorded tests, and the wins counter shows zero victories for each GPU. The RTX 4080 Mobile, however, has a comprehensive set of benchmark scores in the database. Its Geekbench OpenCL score of 159575 and Vulkan score of 145807 demonstrate strong compute performance across different API frameworks. Its Passmark G3D score of 24926 reflects substantial 3D graphics throughput, while the Passmark G2D score of 929 indicates moderate 2D performance.

The Passmark suite shows the RTX 4080 Mobile's DirectX performance profile. It scores 286 in DirectX 9, 244 in DirectX 11, 157 in DirectX 10, and 96 in DirectX 12. The GPU compute score is 11191. These results show a pattern where older DirectX versions produce higher relative scores, with DirectX 9 being the strongest at 286 and DirectX 12 the weakest at 96.

The RTX 4080 Mobile's average benchmark score of 38135 places it in a competitive position relative to its nearest rivals. It trails the NVIDIA GeForce MX570 by just 0.4% and the RTX 5080 Mobile by 0.6%. It leads the RTX 4070 by 1.3% and the Tesla P4 by 1.3%. These narrow deltas indicate that the RTX 4080 Mobile sits at a performance equilibrium point among these four GPUs, with differences below 2% in all cases.

The W7400 has no benchmark scores recorded in the database and no nearest rivals listed. Its percentile ranking of 50 places it exactly in the middle of all GPUs in the database, which is consistent with its modest compute specification. The RTX 4080 Mobile's percentile ranking of 81 places it well above the median, indicating it outperforms roughly eight out of every ten GPUs in the database. The absence of recorded benchmarks for the W7400 means the database cannot provide a direct performance comparison, but the specification differences alone indicate the RTX 4080 Mobile holds a significant advantage in raw compute throughput, memory bandwidth, and feature support.
