Where Each One Wins

The RTX 5070 Ti Mobile wins every benchmark where both are tested. In Geekbench OpenCL, its 143,870 score is roughly 4.1x the AMD's 35,027. In Vulkan, the gap narrows slightly but NVIDIA still leads by 3.5x (139,213 vs 39,286). However, the Radeon PRO W6400 shows relative strength in Vulkan compared to its own OpenCL performance — its Vulkan score is 12.2% higher than its OpenCL score, while NVIDIA's Vulkan score is 3.2% lower than its OpenCL result.

The AMD card's wins are structural rather than performance-based. It is a single-slot workstation card with no power connectors and a 250 W suggested PSU, making it suitable for compact professional systems. The NVIDIA card is an IGP (integrated graphics processor) for mobile devices, with display outputs described as "portable device dependent," meaning it relies on the host laptop's display infrastructure.

For raw compute throughput, the RTX 5070 Ti Mobile delivers 17.04 TFLOPS FP32 versus 3.565 TFLOPS for the Radeon PRO W6400. NVIDIA also provides 184 tensor cores and 46 RT cores, while AMD offers 12 RT cores and no tensor core equivalents. The NVIDIA card supports FP16 at 1:1 ratio (17.04 TFLOPS), whereas AMD's FP16 is 7.130 TFLOPS at 2:1 ratio — meaning AMD trades half its FP32 throughput for FP16.

Architecture Differences

The two GPUs represent entirely different architectural generations and design philosophies. AMD's Radeon PRO W6400 uses the Navi 24 chip on RDNA 2.0 architecture, fabricated on TSMC's 6 nm process. NVIDIA's RTX 5070 Ti Mobile uses the GB205 chip on Blackwell 2.0, built on TSMC's 5 nm node. The process advantage alone explains much of the density gap: NVIDIA fits 31,100 million transistors into 263 mm², while AMD fits 5,400 million into 107 mm².

RDNA 2.0 is AMD's second-generation ray tracing architecture, supporting DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Blackwell 2.0 is NVIDIA's latest architecture for the GeForce 50-series, also supporting DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both support the same API level, but NVIDIA's implementation includes dedicated tensor cores (184) for AI workloads, which AMD's RDNA 2.0 lacks entirely.

The memory subsystems could not be more different. AMD pairs 4 GB of GDDR6 on a 64-bit bus with 2000 MHz memory clock (16 Gbps effective), yielding 128.0 GB/s. NVIDIA uses 12 GB of GDDR7 on a 192-bit bus with 1750 MHz memory clock (28 Gbps effective), yielding 672.0 GB/s. This 5.25x bandwidth advantage is critical for high-resolution textures and compute workloads.

The PCIe interface also differs: AMD uses PCIe 4.0 x4, while NVIDIA uses PCIe 5.0 x16. The x16 link provides up to 4x the bandwidth of x4, and PCIe 5.0 doubles the per-lane throughput versus PCIe 4.0. For a mobile IGP, the bus width matters less since memory is attached directly, but for a discrete workstation card, the x4 link could bottleneck data transfers in certain workloads.

The clock speed comparison is counterintuitive: AMD runs much higher clocks (2039 MHz base, 2321 MHz boost) versus NVIDIA's 847 MHz base and 1447 MHz boost. Yet NVIDIA's massive core count (5888 shading units vs 768) more than compensates. AMD's higher clock rates suggest a more efficiency-focused design, but the raw throughput numbers tell the real story.

Head-to-Head Benchmarks

The Geekbench OpenCL test delivers the most lopsided result in this comparison. NVIDIA's RTX 5070 Ti Mobile scores 143,870, while AMD's Radeon PRO W6400 manages 35,027. The -75.7% delta means AMD achieves less than a quarter of NVIDIA's raw compute score. This aligns with the FP32 gap: NVIDIA's 17.04 TFLOPS is 4.78x AMD's 3.565 TFLOPS, and the OpenCL benchmark closely tracks that ratio.

Geekbench Vulkan narrows the gap slightly. NVIDIA scores 139,213 versus AMD's 39,286, a -71.8% delta. Interestingly, AMD's Vulkan score (39,286) is 12.2% higher than its OpenCL score (35,027), suggesting RDNA 2.0's Vulkan driver or architecture handles this workload more efficiently. NVIDIA's Vulkan score (139,213) is 3.2% lower than its OpenCL score (143,870), indicating a slight regression in the alternate API.

The RTX 5070 Ti Mobile's nearest rivals in the database include NVIDIA Quadro GV100 (35,520 avg, -0.2% delta), AMD Radeon Pro Duo (35,860 avg, -1.2% delta), NVIDIA A2 (34,690 avg, +2.1% delta), and NVIDIA T1000 (36,289 avg, -2.4% delta). The Radeon PRO W6400's rivals include AMD Radeon RX Vega 56 (37,507 avg, -0.9% delta), NVIDIA Tesla P4 (37,628 avg, -1.3% delta), NVIDIA GeForce RTX 4070 (37,648 avg, -1.3% delta), and NVIDIA GeForce GTX TITAN X (36,530 avg, +1.7% delta).

What is remarkable is that both GPUs sit at the 80th percentile of all GPUs, yet their average benchmark scores differ by only 4.6% (37,157 for AMD vs 35,435 for NVIDIA). This is because the NVIDIA part has many more benchmark entries — including PassMark tests where it scores 24,004 in G3D, 10,101 in GPU compute, but only 151 in DirectX 10 and 102 in DirectX 12. These low DirectX scores drag down its average. The AMD card has only two benchmark entries, both Geekbench tests.

The Verdict

The data is unambiguous: the NVIDIA GeForce RTX 5070 Ti Mobile outperforms the AMD Radeon PRO W6400 in every head-to-head benchmark. In OpenCL, NVIDIA leads by 75.7%; in Vulkan, by 71.8%. The NVIDIA card offers 4.78x the FP32 throughput, 5.25x the memory bandwidth, 3x the memory capacity, and 15.3x the shading units. It also adds 184 tensor cores that AMD's architecture lacks entirely.

However, the Radeon PRO W6400 is a different product category. It is a single-slot, 50 W workstation card with two DisplayPort 1.4a outputs, designed for professional environments requiring compact, low-power discrete graphics. Its 250 W suggested PSU and lack of power connectors make it drop-in compatible with many existing systems. The RTX 5070 Ti Mobile is an IGP for laptops, with display outputs dependent on the host device, making it unsuitable as a drop-in desktop upgrade.

For users needing maximum compute performance in a mobile or laptop form factor, the RTX 5070 Ti Mobile is the clear choice based on benchmark results. For users requiring a low-profile, low-power workstation GPU with dedicated display outputs for compact desktop systems, the Radeon PRO W6400 remains a viable option — but its end-of-life status and 4 GB memory limit make it increasingly difficult to recommend for modern workloads.

The 80th percentile placement for both cards masks their true positioning. The AMD card achieves this with minimal resources (768 cores, 50 W TDP), while NVIDIA achieves it with overwhelming compute power (5,888 cores, 60 W TDP) but suffers from inconsistent benchmark scores across different test suites. The RTX 5070 Ti Mobile's PassMark DirectX scores (151, 237, 102, 259) are anomalously low compared to its G3D score (24,004), suggesting driver or test harness issues rather than hardware limitations. In contrast, the Radeon PRO W6400 shows consistent performance across its two Geekbench tests.

Ultimately, these GPUs should not be cross-shopped. The RTX 5070 Ti Mobile is the superior performer by every measurable metric in the head-to-head data. The Radeon PRO W6400's only advantages are its smaller footprint, lower TDP, and dedicated display outputs — factors that matter for specific workstation use cases but do not close the performance chasm demonstrated by the benchmark results.
