AMD Radeon PRO W7400 vs NVIDIA RTX 4000 Ada Generation Comparison

Head-to-Head Benchmarks

The data available for direct comparison is limited, as the AMD Radeon PRO W7400 has no recorded benchmark scores in the database, while the NVIDIA RTX 4000 Ada Generation has two recorded results. This makes a full head-to-head statistical comparison impossible, but the NVIDIA card's recorded performance can be contextualized against its nearest rivals, and the AMD card's theoretical specifications can be examined alongside that data.

The NVIDIA RTX 4000 Ada Generation delivers a Geekbench OpenCL score of 146,593 and a Geekbench Vulkan score of 123,842. Its average benchmark score across all recorded tests is 135,218. This average places it in the 95th percentile of all GPUs in the database, indicating that it outperforms the vast majority of recorded graphics cards. The AMD Radeon PRO W7400, by contrast, has an average benchmark score of 0 and sits in the 50th percentile, with no benchmark entries to support any empirical comparison.

The NVIDIA card's nearest rival in terms of average score is the NVIDIA A10M, which scores 135,230, a delta of 0% from the RTX 4000 Ada. This means the two cards are essentially tied in aggregate performance. The AMD Radeon PRO W6800 trails by a negligible 0.1% with a score of 135,396. The AMD Radeon Pro W6800X Duo scores 135,774, a delta of -0.4%, and the AMD Radeon PRO V620 scores 136,472, a delta of -0.9%. These figures show that the RTX 4000 Ada Generation is statistically indistinguishable from its closest competitors, with all deltas within 1% of its own average.

Since the AMD Radeon PRO W7400 has no recorded benchmarks, the only quantitative comparison available comes from its theoretical specifications. The NVIDIA card's FP32 compute throughput is 26.73 TFLOPS, while the AMD card is rated at 7.885 TFLOPS. This means the NVIDIA card has approximately 3.4 times the raw single-precision compute capability. The texture fill rate shows a similar gap: 417.6 GTexel/s for NVIDIA versus 123.2 GTexel/s for AMD, a factor of roughly 3.4. Pixel rate is 139.2 GPixel/s versus 70.40 GPixel/s, a smaller but still substantial 1.98 times advantage for NVIDIA.

Memory bandwidth also favors the NVIDIA card decisively. The RTX 4000 Ada Generation provides 360.0 GB/s of bandwidth, while the Radeon PRO W7400 provides 172.8 GB/s, exactly half. The NVIDIA card also carries 20 GB of GDDR6 memory compared to 8 GB on the AMD card, a 2.5 times capacity advantage. These specification gaps suggest that in any memory-intensive or compute-heavy workload, the NVIDIA card would hold a commanding lead, but without recorded AMD benchmarks, the actual magnitude cannot be confirmed.

The Verdict

The recorded data shows a clear outcome for anyone choosing between these two cards: the NVIDIA RTX 4000 Ada Generation is the superior performer by every measurable specification and has verified benchmark scores to back it up. Its average benchmark score of 135,218 places it in the 95th percentile of all GPUs, while the AMD Radeon PRO W7400 has no recorded scores and sits at the 50th percentile by default. The NVIDIA card's FP32 throughput of 26.73 TFLOPS is over three times the AMD card's 7.885 TFLOPS, and its 360.0 GB/s memory bandwidth is double the AMD card's 172.8 GB/s.

The AMD card does have advantages in specific areas that might matter for certain deployments. It draws only 55 W of power compared to the NVIDIA card's 130 W, a reduction of more than half. It requires no external power connectors, while the NVIDIA card uses a single 16-pin connector. The AMD card is also physically smaller at 168 mm in length versus 245 mm for the NVIDIA card, and thinner at 20 mm width versus an unspecified width for NVIDIA. These factors make the AMD card suitable for constrained environments where power and space are at a premium.

However, the performance gap is too large to ignore. The NVIDIA card's pixel rate of 139.2 GPixel/s and texture rate of 417.6 GTexel/s dwarf the AMD card's 70.40 GPixel/s and 123.2 GTexel/s. The NVIDIA card also offers 48 ray tracing cores and 192 tensor cores, while the AMD card has 28 ray tracing cores and no tensor cores. For any workload that leverages ray tracing, AI inference, or high-throughput rendering, the NVIDIA card is the only defensible choice based on the data.

The database indicates that the NVIDIA card's nearest rivals are all within 1% of its average score, meaning it is part of a tightly clustered group of high-end workstation GPUs. The AMD Radeon PRO W7400, with no benchmark data, cannot be placed in that cluster. The verdict is straightforward: the NVIDIA RTX 4000 Ada Generation delivers verified, top-tier performance, while the AMD Radeon PRO W7400 offers only theoretical specifications and a much lower power envelope. Users who need maximum compute and memory throughput should select the NVIDIA card. Users who prioritize low power draw, minimal physical footprint, and no external power cabling might consider the AMD card, but they must accept a substantial reduction in raw performance.

Specification Differences

The two cards differ across nearly every major specification category. The NVIDIA RTX 4000 Ada Generation uses the AD104 chip on a 5 nm process, while the AMD Radeon PRO W7400 uses the Navi 33 chip on a 6 nm process. Both are fabricated by TSMC, but the NVIDIA chip contains 35,800 million transistors on a 294 mm² die, while the AMD chip contains 13,300 million transistors on a 204 mm² die. This results in a transistor density of 121.8M per mm² for NVIDIA and 65.2M per mm² for AMD.

Clock speeds differ substantially. The NVIDIA card has a base clock of 1500 MHz and a boost clock of 2175 MHz. The AMD card has a base clock of 330 MHz and a boost clock of 1100 MHz. Memory clocks are 2250 MHz (18 Gbps effective) for NVIDIA and 1350 MHz (10.8 Gbps effective) for AMD.

The compute resources are heavily skewed toward NVIDIA. The NVIDIA card has 6144 shading units, 192 texture mapping units, 64 ROPs, 48 ray tracing cores, and 192 tensor cores. The AMD card has 1792 shading units, 112 texture mapping units, 64 ROPs, and 28 ray tracing cores, with no tensor cores. FP32 performance is 26.73 TFLOPS for NVIDIA and 7.885 TFLOPS for AMD. FP16 performance is also 26.73 TFLOPS (1:1) for NVIDIA and 7.885 TFLOPS (1:1) for AMD.

Memory configuration differs in size, bus width, and bandwidth. The NVIDIA card has 20 GB of GDDR6 on a 160-bit bus, delivering 360.0 GB/s. The AMD card has 8 GB of GDDR6 on a 128-bit bus, delivering 172.8 GB/s. Pixel rate is 139.2 GPixel/s for NVIDIA and 70.40 GPixel/s for AMD. Texture rate is 417.6 GTexel/s for NVIDIA and 123.2 GTexel/s for AMD.

Physical and power characteristics also diverge. The NVIDIA card has a TDP of 130 W, requires a single 16-pin power connector, and has a suggested PSU of 300 W. The AMD card has a TDP of 55 W, requires no power connectors, and has a suggested PSU of 250 W. Both are single-slot cards, but the NVIDIA card is longer at 245 mm (9.6 inches) and taller at 112 mm (4.4 inches), while the AMD card is 168 mm (6.6 inches) long and 69 mm (2.7 inches) tall. The AMD card has a width of 20 mm (0.8 inches), while the NVIDIA card's width is not recorded.

The bus interface differs: NVIDIA uses PCIe 4.0 x16, while AMD uses PCIe 4.0 x8. Display outputs also differ, with the NVIDIA card offering 4x DisplayPort 1.4a and the AMD card offering 4x DisplayPort 2.1. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Architecture Differences

The two cards represent fundamentally different GPU architectures. The NVIDIA RTX 4000 Ada Generation is built on the Ada Lovelace architecture, which is part of the GeForce 40-series generation. The AMD Radeon PRO W7400 is built on the RDNA 3.0 architecture, part of the Radeon Pro Navi (Navi III Series) generation. The NVIDIA card's codename is not recorded, while the AMD card's codename is Hotpink Bonefish.

The manufacturing process differs by one generation node. NVIDIA uses a 5 nm process, while AMD uses a 6 nm process, both from TSMC. This process advantage, combined with a larger die (294 mm² versus 204 mm²), allows NVIDIA to pack nearly 2.7 times more transistors (35,800 million versus 13,300 million). The process node also contributes to higher clock speeds, as the NVIDIA card boosts to 2175 MHz versus 1100 MHz for AMD.

The architecture difference manifests most clearly in specialized compute units. The Ada Lovelace architecture includes 192 tensor cores, which are dedicated to AI and deep learning workloads. The RDNA 3.0 architecture has no tensor cores. Ray tracing hardware also differs, with NVIDIA providing 48 RT cores versus AMD's 28. This means the NVIDIA card has 1.7 times more ray tracing cores and an exclusive tensor core capability.

The shading architecture is also distinct. NVIDIA's Ada Lovelace uses 6144 shading units and 192 TMUs, while AMD's RDNA 3.0 uses 1792 shading units and 112 TMUs. The ROP count is identical at 64, but the NVIDIA card achieves a higher pixel rate due to its higher clock speeds. The FP16 to FP32 ratio is 1:1 on both cards, but the absolute throughput is much higher on the NVIDIA card.

Memory architecture differs in bus width and capacity. The NVIDIA card uses a 160-bit memory bus, which is unusual but effective, paired with 20 GB of GDDR6. The AMD card uses a 128-bit bus with 8 GB of GDDR6. Both use GDDR6 memory, but the NVIDIA card's effective data rate of 18 Gbps is higher than AMD's 10.8 Gbps, resulting in more than double the bandwidth.

The production status for both cards is Active, but their release dates are separated by roughly two years. The NVIDIA RTX 4000 Ada Generation was released on August 8, 2023, while the AMD Radeon PRO W7400 was released on August 2, 2025. The NVIDIA card's predecessor is Workstation Ampere, and its successor is Blackwell PRO W. The AMD card's predecessor is Radeon Pro Vega, and it has no recorded successor. These architectural and generational differences explain the substantial performance gap observed in the specification data.
