AMD Radeon Pro W5700 vs NVIDIA GeForce RTX 3080 Mobile Comparison

Where Each One Wins

The benchmark data splits this comparison cleanly by workload era. NVIDIA GeForce RTX 3080 Mobile dominates modern API performance, winning 7 of 9 head-to-head tests. AMD Radeon Pro W5700 takes only 2 wins, but those wins are telling: legacy DirectX 9 and 2D graphics.

The RTX 3080 Mobile's largest margins come in compute and modern graphics APIs. It leads by 28.8% in Geekbench OpenCL (104831 vs 74613) and by 32.1% in Geekbench Vulkan (104066 vs 70706). DirectX 11 and DirectX 12 show similar patterns, with NVIDIA ahead by 28.8% and 25% respectively. These are not marginal differences; the NVIDIA part is decisively faster wherever contemporary game engines or GPU compute workloads are involved.

The W5700's wins reveal its specialized character. In Passmark DirectX 9, it scores 225 versus 170 — a 32.4% advantage. In Passmark G2D, it posts 899 versus 637, a 41.1% lead. These results suggest the AMD card retains strength in older DirectX 9 titles and 2D rendering tasks, likely due to driver optimization for professional OpenGL-adjacent workflows rather than raw hardware throughput.

The overall average benchmark scores reflect this split: W5700 averages 25726 across all tests, placing in the 71st percentile of all GPUs. RTX 3080 Mobile averages 23628, sitting in the 69th percentile. The AMD card's higher average despite fewer wins comes from its massive G2D and DX9 advantages pulling up the mean. The RTX 3080 Mobile's nearest rival is NVIDIA GeForce GTX TITAN Z (avg 23736, delta -0.5%), while W5700 sits within 0.4% of AMD Radeon RX 6700M (avg 25633) and 0.1% behind NVIDIA GeForce RTX 3080 Ti Mobile (avg 25740).

Architecture Differences

These are fundamentally different designs from different foundries and eras. The W5700 uses AMD's Navi 10 chip on RDNA 1.0 architecture, built on a 7 nm TSMC process. It packs 10,300 million transistors into a 251 mm² die, yielding a transistor density of 41.0M per mm². The RTX 3080 Mobile uses NVIDIA's GA104 chip on Ampere architecture, fabricated on Samsung's 8 nm node. It contains 17,400 million transistors across a 392 mm² die, for 44.4M per mm² density.

The compute resource disparity is stark. RTX 3080 Mobile has 6144 shading units, 192 TMUs, and 96 ROPs. W5700 counters with 2304 shading units, 144 TMUs, and 64 ROPs. More importantly, the NVIDIA part includes 48 RT cores and 192 tensor cores — hardware the AMD card lacks entirely. This explains the RTX 3080 Mobile's DirectX 12 Ultimate (12_2) support versus W5700's DirectX 12 (12_1). The NVIDIA card is built for hardware-accelerated ray tracing and AI workloads; the AMD card has no such dedicated units.

Clock speeds tell the inverse story. W5700 runs at 1400 MHz base and 1880 MHz boost, while RTX 3080 Mobile operates at 1110 MHz base and 1545 MHz boost. The AMD card's higher clocks partially compensate for fewer shading units, but not enough — its FP32 throughput of 8.663 TFLOPS is less than half of NVIDIA's 18.98 TFLOPS. FP16 performance differs even more fundamentally: W5700 delivers 17.33 TFLOPS at a 2:1 ratio, while RTX 3080 Mobile provides 18.98 TFLOPS at 1:1 ratio, meaning no performance penalty for half-precision workloads.

Power draw and physical design diverge sharply. W5700 is a 205 W dual-slot desktop card requiring 1x 6-pin + 1x 8-pin power connectors and a 550 W suggested PSU. RTX 3080 Mobile is a 115 W mobile part with no power connectors listed. The W5700 measures 267 mm in length and 111 mm in height with 5x mini-DisplayPort 1.4a and 1x USB Type-C outputs. The RTX 3080 Mobile has no listed dimensions and its display outputs are "Portable Device Dependent." Both use PCIe 4.0 x16 and 8 GB of GDDR6 on a 256-bit bus with identical 448.0 GB/s bandwidth and 1750 MHz memory clock (14 Gbps effective).

Head-to-Head Benchmarks

The most decisive NVIDIA victory comes in Geekbench Vulkan, where RTX 3080 Mobile scores 104066 against W5700's 70706 — a 32.1% gap. This is the largest percentage difference in any compute test and reflects NVIDIA's stronger driver support for modern cross-platform graphics APIs.

Geekbench OpenCL shows a 28.8% NVIDIA lead (104831 vs 74613). This is notable because OpenCL is often used in professional compute environments, where the W5700's workstation heritage might suggest an advantage. The data contradicts that assumption — the RTX 3080 Mobile's massive shading unit count and 192 tensor cores overwhelm the AMD part's higher clock speed.

DirectX tests follow a consistent pattern. Passmark DirectX 11: 146 vs 104, a 28.8% NVIDIA win. DirectX 12: 72 vs 54, a 25% win. DirectX 10: 120 vs 88, a 26.7% win. The margins are remarkably uniform across these three APIs, suggesting a general rasterization throughput advantage rather than API-specific optimization. Passmark G3D confirms this with an 11% NVIDIA lead (16321 vs 14520), and GPU Compute shows a 10.7% edge (7276 vs 6495).

AMD's wins are concentrated and dramatic. Passmark DirectX 9: 225 vs 170, a 32.4% AMD advantage — the single largest win for either side. Passmark G2D: 899 vs 637, a 41.1% blowout. These results indicate the W5700 retains exceptional legacy DirectX 9 performance and superior 2D rendering capability, likely valuable for older professional applications that never migrated to modern APIs.

Q: What is the transistor density difference?

A: The RTX 3080 Mobile has higher density at 44.4M transistors per mm², despite using a larger 8 nm Samsung process. The W5700's 7 nm TSMC process yields 41.0M per mm². The NVIDIA die is 392 mm² versus AMD's 251 mm², with 17,400 million transistors versus 10,300 million.

Q: Which GPU supports hardware ray tracing?

A: Only the RTX 3080 Mobile has dedicated RT cores (48) and tensor cores (192). This enables its DirectX 12 Ultimate (12_2) support, while the W5700 is limited to DirectX 12 (12_1) with no hardware acceleration for ray tracing or AI workloads.

Q: How do the power requirements compare?

A: The W5700 is a 205 W desktop card requiring 1x 6-pin + 1x 8-pin PCIe power connectors and a 550 W suggested PSU. The RTX 3080 Mobile is a 115 W mobile part with no power connectors and no suggested PSU listed, reflecting its laptop integration.

Q: Which GPU has higher average benchmark score?

A: The W5700 averages 25726 across all benchmarks, placing in the 71st percentile of all GPUs. The RTX 3080 Mobile averages 23628, in the 69th percentile. Despite winning fewer head-to-head tests, the W5700's massive 2D and DirectX 9 scores boost its overall average.

The Verdict

Choose the NVIDIA GeForce RTX 3080 Mobile for modern graphics and compute workloads. The data is unambiguous: it wins 7 of 9 benchmarks, with leads of 25-32% across OpenCL, Vulkan, DirectX 10, 11, and 12. Its 18.98 TFLOPS FP32 performance, 6144 shading units, 48 RT cores, and 192 tensor cores make it the superior choice for contemporary games, ray tracing, AI inference, and general GPU compute. The 1:1 FP16 ratio is particularly valuable for machine learning applications where the W5700's 2:1 penalty would halve throughput.

Choose the AMD Radeon Pro W5700 for legacy compatibility and 2D-centric professional workloads. Its 32.4% DirectX 9 advantage and 41.1% G2D lead suggest it remains viable for older CAD, GIS, or visualization applications that rely on DirectX 9 rendering or heavily exercise 2D paths. The dual-slot 205 W desktop design with 5x mini-DisplayPort 1.4a and USB Type-C outputs offers fixed workstation connectivity, whereas the RTX 3080 Mobile's outputs are portable-device dependent.

The RTX 3080 Mobile's higher average benchmark score does not match its head-to-head dominance — the W5700's 25726 average versus 23628 comes entirely from its extraordinary legacy performance. For any workload using DirectX 10 or newer, or any modern compute API, the NVIDIA part is the clear winner. The W5700's niche is narrow but real: applications frozen in the DirectX 9 era will run faster on AMD hardware. Everything else belongs to NVIDIA.
