Architecture Differences

The two GPUs come from different architectural families and process nodes. The NVIDIA GeForce RTX 4070 Ti uses the Ada Lovelace architecture on a 5 nm process at TSMC, built around the AD104 chip with 35,800 million transistors on a 294 mm² die. The AMD Radeon PRO W6400 uses the RDNA 2.0 architecture on a 6 nm process at TSMC, built around the Navi 24 chip with 5,400 million transistors on a 107 mm² die. The transistor density reflects the difference: 121.8M per mm² for the NVIDIA chip, versus 50.5M per mm² for the AMD chip.

The RTX 4070 Ti features 7,680 shading units, 240 texture mapping units, and 80 raster output pipelines. The W6400 has 768 shading units, 48 TMUs, and 32 ROPs. Ray tracing hardware also differs: the RTX 4070 Ti has 60 RT cores, while the W6400 has 12. The RTX 4070 Ti further includes 240 tensor cores, while the W6400 lists no tensor cores at all. The memory subsystem diverges sharply as well: the RTX 4070 Ti uses 12 GB of GDDR6X on a 192-bit bus, whereas the W6400 uses 4 GB of GDDR6 on a 64-bit bus. The bus interface also differs, with the RTX 4070 Ti using PCIe 4.0 x16 and the W6400 using PCIe 4.0 x4. Both cards share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data points to a clear performance hierarchy. The RTX 4070 Ti dominates in every recorded benchmark, winning both head-to-head tests. In Geekbench OpenCL, the RTX 4070 Ti scores 176,953 versus 35,027 for the W6400, a delta of 405.2%. In Geekbench Vulkan, the RTX 4070 Ti scores 213,808 versus 39,286, a delta of 444.2%. The average score gap is equally stark: 44,795 versus 37,157.

For users choosing between these two, the RTX 4070 Ti is the only option for compute-heavy workloads. Its shading unit count is 10 times higher than the W6400, its FP32 throughput is 40.09 TFLOPS versus 3.565 TFLOPS, and its memory bandwidth is 504.2 GB/s versus 128.0 GB/s. The W6400 is a low-power, single-slot card with a 50 W TDP and no power connectors, making it suitable for constrained systems, but its performance ceiling is far lower.

The RTX 4070 Ti also sits in a different competitive bracket. Its nearest rivals include the RTX 5090 Mobile, the Radeon Pro 5500 XT, and the RTX A6000, all with average scores within 1.7% of each other. The W6400 competes with the RX Vega 56, the Tesla P4, and the RTX 4070, again all within 1.7%. The delta between these two brackets is roughly 20.6% in average score, which is the gap a user should expect when moving from the W6400 to the RTX 4070 Ti.

Specification Differences

The two cards differ across nearly every specification field. The RTX 4070 Ti runs at a base clock of 2310 MHz and a boost clock of 2610 MHz, while the W6400 runs at 2039 MHz base and 2321 MHz boost. The memory clocks are 1313 MHz with 21 Gbps effective for the NVIDIA card, and 2000 MHz with 16 Gbps effective for the AMD card. The RTX 4070 Ti has a pixel rate of 208.8 GPixel/s and a texture rate of 626.4 GTexel/s, versus 74.27 GPixel/s and 111.4 GTexel/s for the W6400. FP32 performance is 40.09 TFLOPS for the RTX 4070 Ti, while the W6400 delivers 3.565 TFLOPS. FP16 performance is 40.09 TFLOPS (1:1) for the RTX 4070 Ti, and 7.130 TFLOPS (2:1) for the W6400.

The RTX 4070 Ti is a dual-slot card with a 285 mm length, 112 mm height, and 42 mm width, requiring a 1x 16-pin power connector and a 600 W suggested PSU. The W6400 is a single-slot card with no power connectors and a 250 W suggested PSU. Display outputs differ: the RTX 4070 Ti has 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the W6400 has 2x DisplayPort 1.4a. The RTX 4070 Ti has a launch MSRP of 799 USD. The W6400 has no recorded launch MSRP.

Head-to-Head Benchmarks

The only two benchmarks shared by both cards are Geekbench OpenCL and Geekbench Vulkan. In both, the RTX 4070 Ti wins decisively. In Geekbench OpenCL, the RTX 4070 Ti scores 176,953, which is 405.2% higher than the W6400's 35,027. In Geekbench Vulkan, the RTX 4070 Ti scores 213,808, which is 444.2% higher than the W6400's 39,286. The delta percentages are among the largest recorded in the database for any pair of GPUs.

Beyond the shared tests, the RTX 4070 Ti has additional benchmark entries that show its range. In 3DMark Steel Nomad DX12, it scores 5,024. In Passmark tests, it scores 187 in DirectX 10, 288 in DirectX 11, 116 in DirectX 12, and 352 in DirectX 9. Its Passmark G2D score is 1,200, its G3D score is 31,624, and its GPU compute score is 18,396. The W6400 has no entries for these tests, so no direct comparison can be made from the recorded data.

The RTX 4070 Ti's nearest rival, the RTX 5090 Mobile, has an average score of 45,152, which is 0.8% higher than the RTX 4070 Ti. The Radeon Pro 5500 XT scores 45,384, 1.3% higher. The RTX A6000 scores 44,075, 1.6% lower. The Intel Arc A730M scores 45,592, 1.7% higher. For the W6400, the RX Vega 56 scores 37,507, 0.9% higher, and the Tesla P4 and RTX 4070 both score 37,628, 1.3% higher. The GTX TITAN X scores 36,530, 1.7% lower.

Where Each One Wins

The RTX 4070 Ti wins in every recorded benchmark category. It holds a 405.2% lead in Geekbench OpenCL and a 444.2% lead in Geekbench Vulkan. Its FP32 throughput is 40.09 TFLOPS, which is more than 11 times that of the W6400. Its texture rate of 626.4 GTexel/s is over 5.6 times higher, and its pixel rate of 208.8 GPixel/s is roughly 2.8 times higher. The RTX 4070 Ti also carries 60 RT cores versus 12, and 240 tensor cores versus none.

The W6400 wins in power and physical footprint. It has a 50 W TDP, which is 235 W lower than the RTX 4070 Ti. It is a single-slot card with no power connectors, while the RTX 4070 Ti is dual-slot with a 1x 16-pin connector. The W6400 also requires a 250 W suggested PSU versus 600 W for the RTX 4070 Ti. For systems with strict power or space constraints, the W6400 is the only viable option from these two.

The use-case split is therefore clear. For raw compute, gaming, ray tracing, and high-resolution texture work, the RTX 4070 Ti is the decisive choice, backed by its 12 GB memory capacity, 504.2 GB/s bandwidth, and 84th percentile ranking. For low-power, single-slot installations where minimal power draw is a priority, the W6400 offers a compact solution with a 50 W TDP and no external power requirement, though its 4 GB memory and 128.0 GB/s bandwidth limit its workload range. The RTX 4070 Ti's 2 wins in head-to-head tests versus 0 for the W6400 leaves no ambiguity in benchmark performance.
