AMD Radeon Pro W5700X vs NVIDIA GeForce RTX 3080 Ti Comparison

Head-to-Head Benchmarks

The recorded data contains two direct head-to-head comparisons, and in both cases the NVIDIA GeForce RTX 3080 Ti delivers a decisive victory. In the Geekbench OpenCL test, the RTX 3080 Ti scores 170,037 against the AMD Radeon Pro W5700X's 43,810, a delta of 74.2% in NVIDIA's favor. The margin is even larger in Geekbench Vulkan, where the RTX 3080 Ti reaches 192,697 while the AMD card manages 45,246, a 76.5% advantage. These are not marginal differences; the NVIDIA card is roughly four times faster in raw compute throughput in both APIs.

Looking at the broader database averages, the gap narrows considerably. The Radeon Pro W5700X holds an average benchmark score of 54,828, while the RTX 3080 Ti averages 41,187, meaning the AMD card actually leads by about 33% in aggregate across all recorded tests. This apparent contradiction is explained by the benchmark set: the AMD card's average is built from Metal, OpenCL, and Vulkan results, while the NVIDIA card's average includes a much wider range of tests including DirectX and Passmark suites. The head-to-head data only covers two common tests, and in those the RTX 3080 Ti is overwhelmingly dominant.

The percentile rankings place both cards in similar territory. The Radeon Pro W5700X sits at the 87th percentile of all GPUs in the database, while the RTX 3080 Ti is at the 83rd percentile. Despite the NVIDIA card's massive compute lead in shared tests, the AMD card's overall standing is slightly higher, driven by its strong Metal performance (75,427 in Geekbench Metal, a test the NVIDIA card does not have recorded). In the nearest rival comparisons, the Radeon Pro W5700X trades blows with the RTX 4080 and RX 6750 GRE-class hardware within 1.7%, while the RTX 3080 Ti sits near the RTX 5070, Tesla M40-class parts within 2%. This positions the AMD card as a top-tier performer in its own right, even if the head-to-head results paint a lopsided picture.

Architecture Differences

The two cards could hardly be more different in their underlying silicon design. The AMD Radeon Pro W5700X uses the Navi 10 chip built on TSMC's 7nm process, with 10,300 million transistors packed into a 251mm² die, yielding a density of 41.0M/mm². The RTX 3080 Ti uses the GA102 chip on Samsung's 8nm process, with 28,300 million transistors across a much larger 628mm² die. This gives the NVIDIA card nearly three times more transistors, and the larger die size, despite the smaller process node, as well as a higher transistor density of 45.1M/mm².

The compute resources reflect this scale. The RTX 3080 Ti packs 10,240 shading units, 320 texture mapping units, 112 ROPs, 80 RT cores, and 320 tensor cores. The AMD card counters with 2,560 shading units, 160 TMUs, and 64 ROPs, representing a fraction of NVIDIA's resources. Pixel throughput and texture throughput are both higher on the NVIDIA card: 186.5 GPixel/s and 532.5 GTexel/s, respectively, compared to the AMD card's 130.6 GPixel/s and 326.4 GTexel/s. Floating point performance is similarly lopsided: the RTX 3080 Ti delivers 34.10 TFLOPS FP32 and 34.10 TFLOPS FP16 (at 1:1), while the AMD card produces 10.44 TFLOPS FP32 and 20.89 TFLOPS FP16 (at 2:1). The NVIDIA card even has dedicated RT and tensor cores, features entirely absent from the AMD part.

Memory configurations differ significantly. The Radeon Pro W5700X provides 16GB of GDDR6 memory on a 256-bit bus, delivering 448.0 GB/s bandwidth. The RTX 3080 Ti offers 12GB of GDDR6X memory on a 384-bit bus, achieving 912.4 GB/s, more than double the bandwidth. The process node advantage goes to AMD (7nm vs 8nm), but the NVIDIA card compensates with a much larger and more powerful chip. The bus interface also differs: the AMD card uses an Apple MPX connector, while the NVIDIA card uses PCIe 4.0 x16. Display outputs are likewise distinct: the AMD card offers 1x HDMI 2.0b and 4x Thunderbolt, while the NVIDIA card has 1x HDMI 2.1 and 3x DisplayPort 1.4a.

API support shows a generation gap. The AMD card supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, adding the hardware ray tracing and mesh shaders implied by the Ultimate tier. Power and physical design also differ: the AMD card consumes 205W and occupies a quad-slot form factor, while the RTX 3080 Ti draws 350W in a dual-slot design with a single 12-pin power connector. The AMD card is 305mm long (12 inches), the NVIDIA card is 285mm (11.2 inches) with a height of 112mm (4.4 inches) and width of 40mm (1.6 inches).

The Verdict

The data makes clear that the NVIDIA GeForce RTX 3080 Ti is the superior choice for raw compute workloads in OpenCL and Vulkan, where it leads by 74.2% and 76.5% respectively. Its 34.10 TFLOPS FP32, 80 RT cores, and 912.4 GB/s memory bandwidth are class-leading figures that dwarf the AMD card's 10.44 TFLOPS and 448.0 GB/s. Users who need maximum throughput in cross-platform compute or modern DirectX 12 Ultimate workloads should favor the RTX 3080 Ti, despite its higher 350W power draw and need for a 750W PSU.

However, the AMD Radeon Pro W5700X holds its own in the broader picture. Its average benchmark score of 54,828 exceeds the RTX 3080 Ti's 41,187, and its 87th percentile rank edges out the NVIDIA card's 83rd. The 16GB GDDR6 memory at 448.0 GB/s, combined with a 205W TDP and quad-slot design, makes it a more power-efficient part in absolute terms, if not in performance-per-watt given the NVIDIA card's massive output. The Apple MPX bus interface and Thunderbolt outputs target a specific ecosystem, while the 4x Thunderbolt display outputs are unique to this card.

For users working within Apple MPX systems or prioritizing Metal performance, the Radeon Pro W5700X is the clear pick, backed by a 75,427 Metal score. For general-purpose compute, ray tracing, or maximum memory bandwidth, the RTX 3080 Ti is the only option with the recorded data. The choice hinges on platform and workload: the AMD card dominates in its niche, the NVIDIA card dominates in the shared benchmarks. Neither card is a universal winner, but the RTX 3080 Ti's decisive head-to-head victories make it the default recommendation for mixed workloads, while the W5700X remains relevant for Apple-centric environments.
