AMD Radeon PRO W7400 vs NVIDIA GeForce RTX 4070 Mobile Comparison

Where Each One Wins

The AMD Radeon PRO W7400 and NVIDIA GeForce RTX 4070 Mobile occupy opposite ends of the mobile and workstation GPU spectrum. The RTX 4070 Mobile is the clear performance leader in every measured category, while the W7400 is a low-power, single-slot professional card with a different set of priorities.

The RTX 4070 Mobile wins all recorded benchmark comparisons. The database shows no benchmark wins for the AMD card. The RTX 4070 Mobile delivers an average benchmark score of 27,435, placing it in the 73rd percentile of all GPUs. The W7400 has an average benchmark score of zero in the database, with no individual benchmark entries recorded, and sits at the 50th percentile.

The RTX 4070 Mobile's advantage is not marginal. Its FP32 compute rating of 15.62 TFLOPS is nearly double the W7400's 7.885 TFLOPS. Texture throughput follows the same pattern: the NVIDIA card processes 244.1 GTexel/s versus 123.2 GTexel/s for AMD. Pixel rate favors NVIDIA as well, at 81.36 GPixel/s compared to 70.40 GPixel/s.

Memory bandwidth is another clear differentiator. The RTX 4070 Mobile delivers 256.0 GB/s across a 128-bit bus, while the W7400 manages 172.8 GB/s on the same bus width. Both cards have 8 GB of GDDR6 memory, but the NVIDIA part accesses it faster.

The use-case split is straightforward. The RTX 4070 Mobile is built for gaming and general compute in laptops, with 4,608 shading units, 144 tensor cores, and 36 RT cores. The W7400 is a professional workstation card with 1,792 shading units, 28 RT cores, and no tensor cores, designed for stability and low power consumption rather than peak throughput.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. AMD uses the Navi 33 chip based on RDNA 3.0 architecture, codenamed Hotpink Bonefish. This is part of the Radeon Pro Navi series, specifically the Navi III generation. NVIDIA uses the AD106 chip based on Ada Lovelace architecture, belonging to the GeForce 40 Mobile series.

Manufacturing processes differ significantly. The W7400 is built on a 6 nm TSMC node, while the RTX 4070 Mobile uses a 5 nm TSMC node. Transistor counts reflect this: the NVIDIA chip packs 22,900 million transistors into a 188 mm² die, giving a density of 121.8 million transistors per square millimeter. The AMD chip contains 13,300 million transistors on a larger 204 mm² die, resulting in a lower density of 65.2 million per square millimeter.

Shader configuration differs dramatically. The RTX 4070 Mobile has 4,608 shading units, 144 texture mapping units, and 48 ROPs. The W7400 has 1,792 shading units, 112 TMUs, and 64 ROPs. NVIDIA's card includes 144 tensor cores and 36 RT cores, while AMD provides 28 RT cores and no tensor core equivalent. The higher ROP count on the AMD card helps narrow the pixel rate gap despite its much lower shader count.

Clock behavior is notable. The W7400 has a very low base clock of 330 MHz and a boost clock of 1,100 MHz. The RTX 4070 Mobile runs at a 1,395 MHz base and 1,695 MHz boost. Memory clocks also differ: AMD runs GDDR6 at 1,350 MHz (10.8 Gbps effective), while NVIDIA runs it at 2,000 MHz (16 Gbps effective), explaining the bandwidth gap.

Power envelopes separate these cards completely. The W7400 has a 55 W TDP, requires no external power connectors, and is a single-slot card measuring 168 mm long. The RTX 4070 Mobile has a 115 W TDP and is an IGP form factor for laptops, with dimensions dependent on the portable device. The AMD card specifies a 250 W suggested PSU, while the NVIDIA part lists none.

Both cards support PCIe 4.0 x8 interfaces. Display outputs differ: the W7400 provides 4x DisplayPort 2.1, while the RTX 4070 Mobile's outputs are portable device dependent. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Release timing also differs. The W7400 released on August 2, 2025, succeeding the Radeon Pro Vega line. The RTX 4070 Mobile released on January 2, 2023, succeeding GeForce 30 Mobile and being succeeded by GeForce 50 Mobile. The NVIDIA card is thus from an earlier generation but still dominates in raw performance.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between these two cards. The RTX 4070 Mobile has a full suite of benchmark scores, while the W7400 has none recorded. This absence itself is informative: the W7400 appears optimized for professional workloads that do not map to the consumer-oriented benchmark suite.

Focusing on the RTX 4070 Mobile's recorded data provides context. Its Geekbench OpenCL score is 109,197 and Vulkan score is 108,367. PassMark results show a G3D score of 19,587, a GPU compute score of 8,399, and a G2D score of 763. Legacy DirectX tests show scores of 223 for DirectX 9, 179 for DirectX 11, 116 for DirectX 10, and 85 for DirectX 12. These numbers indicate strong general compute and gaming performance.

The nearest rivals for the RTX 4070 Mobile place it in a competitive field. The AMD Radeon RX 6700 XT scores 27,425, essentially identical to the RTX 4070 Mobile's 27,435, a delta of 0 percent. The NVIDIA GeForce RTX 3090 scores 27,565, which is 0.5 percent higher than the RTX 4070 Mobile. The NVIDIA RTX PRO 4000 Blackwell scores 27,135, 1.1 percent lower. The AMD Radeon Pro Vega 20 scores 27,839, 1.5 percent higher. This places the RTX 4070 Mobile in a tight cluster of high-end desktop and workstation cards, despite being a mobile part.

The W7400 has no rivals listed in the database and no benchmark scores. Its percentile ranking of 50 versus the RTX 4070 Mobile's 73 suggests it falls well below the NVIDIA card in overall performance distribution, though the lack of recorded benchmarks makes direct quantification impossible.

The Verdict

The data clearly favors the NVIDIA GeForce RTX 4070 Mobile for anyone needing raw compute performance. Its FP32 throughput of 15.62 TFLOPS, texture rate of 244.1 GTexel/s, and memory bandwidth of 256.0 GB/s place it in a different performance class than the AMD Radeon PRO W7400. The RTX 4070 Mobile's 73rd percentile ranking and its competitive standing against desktop cards like the RTX 3090 and RX 6700 XT confirm that this mobile part delivers substantial performance.

The AMD Radeon PRO W7400 serves a different purpose. Its 55 W TDP, single-slot design, and lack of external power connectors make it suitable for compact workstations where power efficiency and space are priorities. The 4x DisplayPort 2.1 outputs and professional Radeon Pro branding target multi-display workstation environments. Its 7.885 TFLOPS FP32 and 172.8 GB/s bandwidth are modest but adequate for professional visualization tasks.

For users choosing between these two, the decision hinges on the workload and system constraints. The RTX 4070 Mobile is the performance choice, delivering roughly double the FP32 compute and 48 percent more memory bandwidth. It also brings 144 tensor cores for AI acceleration, which the W7400 lacks entirely. The W7400 wins on power efficiency, running at 55 W versus 115 W, and on its fixed workstation form factor with four DisplayPort 2.1 outputs.

The RTX 4070 Mobile's benchmark scores against desktop rivals indicate it can handle demanding 3D workloads, compute tasks, and modern games. The W7400 has no recorded benchmarks, making its real-world performance uncertain, but its specs suggest a capable professional card for lighter workloads. The RTX 4070 Mobile is the pick for performance, while the W7400 suits power-constrained professional systems with specific display requirements.
