AMD Radeon Pro W5700 vs NVIDIA GeForce RTX 3080 Ti Mobile Comparison

The NVIDIA GeForce RTX 3080 Ti Mobile and AMD Radeon Pro W5700 sit at nearly identical average benchmark scores, with the NVIDIA part edging ahead by a mere 0.1% (25740 vs 25726). Both GPUs occupy the 71st percentile of all GPUs, making them statistical equals in overall performance, yet the data reveals starkly different personalities: the mobile Ampere chip wins 7 of 9 head-to-head tests, while the desktop RDNA 1.0 card claims 2, mostly in legacy and 2D workloads.

Where Each One Wins

The NVIDIA GeForce RTX 3080 Ti Mobile dominates modern compute and graphics workloads. Its largest margins come in PassMark DirectX 12, where it scores 88 versus 54 for the Radeon, a 63% advantage. In Geekbench OpenCL, the NVIDIA card posts 117866 against 74613, a 58% lead, and in Vulkan it reaches 107502 versus 70706, a 52% gap. These are not small margins; they represent a decisive edge in GPU-accelerated compute and current-generation graphics APIs.

The AMD Radeon Pro W5700 wins two specific tests: PassMark DirectX 9 (225 vs 201, a 10.7% lead) and PassMark G2D (899 vs 818, a 9% lead). The DirectX 9 result suggests the AMD card retains stronger performance in older, fixed-function-heavy workloads, which can matter for legacy enterprise applications. The G2D victory indicates slightly better 2D desktop composition and blitting performance, though the absolute difference of 81 points is modest.

For practical purposes, the NVIDIA card is the choice for modern gaming, machine learning inference, and OpenCL/Vulkan compute. The AMD card holds a niche for older DirectX 9 software and 2D-heavy workflows, but those wins do not offset the scale of NVIDIA's victories in every other tested category.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The NVIDIA GeForce RTX 3080 Ti Mobile uses the GA103 chip on Samsung's 8 nm process, packing 22,000 million transistors into a 496 mm² die (44.4M transistors per mm²). It is built on the Ampere architecture, which includes 58 ray tracing cores and 232 tensor cores—hardware features the AMD card lacks entirely.

The AMD Radeon Pro W5700 uses the Navi 10 chip on TSMC's 7 nm process, with 10,300 million transistors on a 251 mm² die (41.0M per mm²). Its RDNA 1.0 architecture has no ray tracing or tensor cores. The NVIDIA GPU also has a much larger execution resource pool: 7424 shading units, 232 TMUs, and 96 ROPs, versus 2304 shading units, 144 TMUs, and 64 ROPs on the AMD. Despite this 3.2x shading unit advantage, the NVIDIA card's FP32 throughput is 18.71 TFLOPS, only 2.16x the AMD's 8.663 TFLOPS, because the AMD GPU runs at higher clocks (1400 MHz base / 1880 MHz boost vs 810 MHz base / 1260 MHz boost).

Memory configurations differ sharply. The NVIDIA card has 16 GB GDDR6 on a 256-bit bus, delivering 512.0 GB/s bandwidth. The AMD card has 8 GB GDDR6 on the same 256-bit bus, yielding 448.0 GB/s. The NVIDIA part also supports DirectX 12 Ultimate (12_2), while the AMD card is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

Head-to-Head Benchmarks

The single biggest win for the NVIDIA GeForce RTX 3080 Ti Mobile comes in PassMark DirectX 12, where its score of 88 beats the AMD's 54 by 63%. This is a massive gap in the most modern graphics API tested, indicating the NVIDIA architecture handles contemporary rendering features far more efficiently. The Geekbench OpenCL result shows a 58% lead (117866 vs 74613), demonstrating superior general-purpose compute throughput. Vulkan follows closely at 52% (107502 vs 70706), which is particularly relevant for cross-platform games and professional applications using Vulkan.

PassMark DirectX 11 shows a 57.7% NVIDIA advantage (164 vs 104), and DirectX 10 shows a 48.9% lead (131 vs 88). The PassMark G3D score, which aggregates 3D rendering performance, gives NVIDIA a 32.8% win (19288 vs 14520). PassMark GPU Compute also favors NVIDIA by 30.4% (8471 vs 6495).

The AMD Radeon Pro W5700's two wins are smaller in magnitude. Its PassMark DirectX 9 score of 225 beats NVIDIA's 201 by 10.7%, and its PassMark G2D score of 899 beats 818 by 9%. These are niche victories in legacy and 2D workloads. Notably, no benchmark test shows the AMD card winning by more than 11%, while NVIDIA wins by 30% or more in five separate tests.

The Verdict

The data points to a clear split. The NVIDIA GeForce RTX 3080 Ti Mobile is the superior GPU for virtually all modern workloads. Its 63% DirectX 12 advantage, 58% OpenCL advantage, and 52% Vulkan advantage make it the obvious choice for gaming, 3D rendering, and compute-heavy tasks. The inclusion of 58 ray tracing cores and 232 tensor cores means it can handle hardware-accelerated ray tracing and AI workloads that the AMD card cannot process at all. Its 16 GB memory buffer also provides twice the capacity of the AMD card, which is critical for large datasets and high-resolution textures.

The AMD Radeon Pro W5700 is a workstation card with a 205 W TDP and dual-slot design, making it appropriate for desktop systems with adequate power delivery (550 W suggested PSU). Its wins in DirectX 9 and G2D suggest it retains usefulness for legacy enterprise software and 2D design work. However, its 8 GB memory and lack of ray tracing cores limit its future-proofing. The NVIDIA mobile part achieves near-identical average performance (25740 vs 25726) while consuming 115 W versus 205 W, a significant efficiency advantage. For anyone who needs a GPU that excels in modern APIs and compute, choose the NVIDIA. For legacy DirectX 9 compatibility and 2D desktop performance in a desktop workstation, the AMD card has a narrow but real edge. The overall verdict from the benchmark data is that the NVIDIA GeForce RTX 3080 Ti Mobile is the more capable and versatile GPU, winning 7 of 9 tests with larger margins than the AMD card's 2 narrow victories.
