AMD Radeon PRO W6400 vs NVIDIA GeForce RTX 5070 Ti Comparison

The Verdict

The data separates these two GPUs into entirely different performance tiers. The NVIDIA GeForce RTX 5070 Ti is the clear choice for demanding workloads, delivering benchmark scores that dwarf the AMD Radeon PRO W6400 by a factor of five or more. The RTX 5070 Ti sits at the 86th percentile among all GPUs in the database, while the W6400 ranks at the 80th percentile, but that percentile gap understates the massive absolute performance difference. For users needing high-end compute, ray tracing, or 4K-class rendering, the RTX 5070 Ti is the only rational pick. The W6400, meanwhile, is a low-power, single-slot professional card suited for basic 2D workloads, legacy compatibility, or scenarios where power draw and physical footprint matter more than raw throughput. It is end-of-life and offers no contest in compute-bound tasks. If the workload is light, the W6400's 50 W power draw and slotless power connector requirement make it an easy fit for compact systems. If the workload is heavy, the RTX 5070 Ti's 300 W draw and 16-pin connector are the price of entry for its dominant performance.

Architecture Differences

The two cards come from opposite ends of the GPU design spectrum. The NVIDIA GeForce RTX 5070 Ti uses the GB203 chip built on TSMC's 5 nm process, packing 45,600 million transistors into a 378 mm² die for a transistor density of 120.6 million per square millimeter. Its Blackwell 2.0 architecture supports the full modern feature set: DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The AMD Radeon PRO W6400 uses the Navi 24 chip on TSMC's 6 nm node, with 5,400 million transistors on a 107 mm² die, a transistor density of 50.5 million per square millimeter. It runs RDNA 2.0 and also supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, so API coverage is identical despite the generational gap.

Core counts tell the story of scale. The RTX 5070 Ti features 8,960 shading units, 280 texture mapping units, 96 ROPs, 70 ray tracing cores, and 280 tensor cores. The W6400 has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores, with no tensor core equivalent. That is an 11.7x difference in shading units and a 5.8x difference in ray tracing cores. Clock speeds are closer than the core counts: the RTX 5070 Ti runs at 2295 MHz base and 2452 MHz boost, while the W6400 runs at 2039 MHz base and 2321 MHz boost. The RTX 5070 Ti still leads, but the architecture's advantage comes mostly from having far more execution resources, not from a radically higher clock.

Memory is another chasm. The RTX 5070 Ti carries 16 GB of GDDR7 on a 256-bit bus with 896.0 GB/s of bandwidth, running at 1750 MHz (28 Gbps effective). The W6400 has 4 GB of GDDR6 on a 64-bit bus with 128.0 GB/s of bandwidth, at 2000 MHz (16 Gbps effective). That is a 4x capacity difference and a 7x bandwidth advantage for the NVIDIA card. Pixel rate is 235.4 GPixel/s versus 74.27 GPixel/s, and texture rate is 686.6 GTexel/s versus 111.4 GTexel/s. FP32 throughput is 43.94 TFLOPS versus 3.565 TFLOPS, a 12.3x gap. FP16 performance is 43.94 TFLOPS (1:1) on the RTX 5070 Ti, while the W6400 delivers 7.130 TFLOPS (2:1). The RTX 5070 Ti also has a wider PCIe 5.0 x16 interface versus the W6400's PCIe 4.0 x4, which matters for data transfer in compute scenarios.

Physical and power characteristics diverge sharply. The RTX 5070 Ti is a dual-slot card, 304 mm long, 137 mm tall, and 48 mm wide, with a 300 W TDP and a single 16-pin power connector, requiring a 700 W power supply. The W6400 is a single-slot card with a 50 W TDP, no power connector, and a 250 W suggested PSU. Display outputs differ as well: the RTX 5070 Ti offers 1x HDMI 2.1b and 3x DisplayPort 2.1b, while the W6400 offers only 2x DisplayPort 1.4a. The RTX 5070 Ti launched on 2025-02-19 and remains in active production; the W6400 launched on 2022-01-18 and is now end-of-life.

Head-to-Head Benchmarks

The database records two shared benchmark tests between these cards, and both are landslides. In Geekbench OpenCL, the RTX 5070 Ti scores 212,363 against the W6400's 35,027, a 506.3% advantage. That is not a marginal win; it is a six-fold difference in raw compute throughput. OpenCL is a common proxy for general-purpose GPU compute, and the result reflects the massive disparity in shading units, memory bandwidth, and FP32 throughput. The W6400's 3.565 TFLOPS of FP32 simply cannot compete with 43.94 TFLOPS.

In Geekbench Vulkan, the RTX 5070 Ti scores 225,122 versus 39,286, a 473% delta. Vulkan is the more modern graphics API, and the NVIDIA card again dominates. The gap narrows slightly compared to OpenCL, likely because Vulkan's lower overhead reduces some of the architectural penalties, but the RTX 5070 Ti still outperforms by nearly five times. The W6400's 12 ray tracing cores and 768 shading units are not enough to make any dent in this comparison.

Across the two head-to-head tests, the RTX 5070 Ti wins both, with a combined 2-0 record. The average benchmark score for the RTX 5070 Ti is 49,957, while the W6400's average is 37,157. That 34.4% average difference is much smaller than the head-to-head deltas, because the average includes the RTX 5070 Ti's other tests (3DMark Steel Nomad, Passmark DX9 through DX12, Passmark G2D/G3D, and GPU Compute) where it also posts strong numbers: 3DMark Steel Nomad at 6,604, Passmark G3D at 32,974, and Passmark GPU Compute at 20,203. The W6400 only has the two Geekbench scores in the database, which pulls its average down. The RTX 5070 Ti's nearest rival is the AMD Radeon RX Vega 64 at an average score of 50,001, a 0.1% difference, meaning the RTX 5070 Ti sits essentially at parity with that older high-end card in average terms, despite being far ahead in the two shared tests. The W6400's nearest rival is the AMD Radeon RX Vega 56 at 37,507, a 0.9% gap, so the W6400 is also close to its own peer group.

Where Each One Wins

The RTX 5070 Ti wins every measurable compute and graphics scenario in this comparison. Its 16 GB of GDDR7 with 896.0 GB/s bandwidth makes it suitable for large datasets, high-resolution textures, and memory-intensive rendering tasks. The 43.94 TFLOPS of FP32 and 43.94 TFLOPS of FP16 (1:1) enable heavy simulation, AI inference, and compute workloads. The 70 ray tracing cores and 280 tensor cores give it a clear path for ray-traced rendering and DLSS-style acceleration, though the latter is not benchmarked here. The 3DMark Steel Nomad score of 6,604 and Passmark G3D score of 32,974 confirm strong DirectX 12 and general 3D performance. Its PCIe 5.0 x16 interface also ensures fast data transfer from the CPU, which matters in professional content creation.

The W6400 has no benchmark wins in the head-to-head data, but it has a different set of strengths that are not captured by raw performance numbers. Its 50 W TDP and single-slot design make it ideal for space-constrained or low-power systems. It requires no external power connector, so it can drop into almost any chassis with a 250 W power supply. Its 2x DisplayPort 1.4a outputs are sufficient for basic multi-monitor setups. The 6 nm process and 107 mm² die mean it is a small, efficient chip, and its end-of-life status suggests it may be available at reduced cost in the secondary market, though the database does not track that. For 2D workstation tasks, legacy software compatibility, or as a display adapter in a server or industrial PC, the W6400 is a practical choice.

The decision hinges on workload intensity. If the task requires more than 128.0 GB/s of memory bandwidth or more than 3.565 TFLOPS of FP32, the W6400 will bottleneck. The RTX 5070 Ti clears those thresholds by factors of 7 and 12, respectively. If the task is light enough to fit within 4 GB of memory and 50 W of power, the W6400 offers a simpler physical installation and lower system-wide power draw. The RTX 5070 Ti, by contrast, demands a 700 W PSU, a 16-pin connector, and a dual-slot footprint. The data shows no scenario where the W6400 outperforms the RTX 5070 Ti in compute or graphics benchmarks, so the RTX 5070 Ti is the default choice for anyone who needs performance. The W6400 is only preferable when its power and size constraints are the primary concern.
