AMD Radeon PRO W7400 vs NVIDIA GeForce RTX 4090 D Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Radeon PRO W7400 and the NVIDIA GeForce RTX 4090 D. The AMD card has no recorded benchmark entries, while the NVIDIA card shows three separate test results. The RTX 4090 D scores 8,587 in 3DMark Steel Nomad DX12, 278,621 in Geekbench OpenCL, and 246,941 in Geekbench Vulkan. Its average benchmark score across these entries stands at 178,050, placing it in the 98th percentile of all GPUs in the database.

The Radeon PRO W7400 shows a 50th percentile ranking among all GPUs, but with an average benchmark score of zero, it cannot be directly compared numerically in any test. The absence of benchmark data for the AMD card means the only available quantitative comparison comes from architectural specifications rather than measured performance. The RTX 4090 D's nearest rivals in the database include the NVIDIA RTX PRO 5000 Blackwell with an average score of 182,109 (2.2% higher), the NVIDIA A100 SXM4 80 GB at 183,725 (3.1% higher), the NVIDIA RTX 5000 Ada Generation at 184,664 (3.6% higher), and the NVIDIA A100 SXM4 40 GB at 187,147 (4.9% higher). These deltas indicate the RTX 4090 D trails the top professional cards in the database by a narrow margin, between 2.2% and 4.9%.

For the AMD card, the specifications suggest a vastly different performance envelope. The FP32 compute rate of 7.885 TFLOPS compares to 73.54 TFLOPS for the NVIDIA card, a difference of nearly an order of magnitude. Pixel throughput stands at 70.40 GPixel/s versus 443.5 GPixel/s, and texture rate at 123.2 GTexel/s versus 1,149.1 GTexel/s. These figures indicate the NVIDIA part delivers roughly nine times the raw throughput in each category, though no benchmark data exists to confirm real-world scaling.

The Verdict

The recorded data shows a clear segmentation between these two products. The NVIDIA GeForce RTX 4090 D sits at the 98th percentile of all GPUs with an average benchmark score of 178,050, while the AMD Radeon PRO W7400 sits at the 50th percentile with no recorded benchmark scores. The RTX 4090 D holds a 24 GB GDDR6X frame buffer with 1.01 TB/s bandwidth, compared to the W7400's 8 GB GDDR6 at 172.8 GB/s. The difference in memory capacity alone, 16 GB, represents a substantial gap for large data sets or high-resolution textures.

The RTX 4090 D also carries 456 tensor cores and 114 ray tracing cores, while the W7400 lists 28 ray tracing cores and no tensor core entry. The NVIDIA card's 1,599 USD launch MSRP reflects its positioning as a high-end compute and rendering solution. The AMD card, with no launch MSRP recorded, targets a different segment entirely based on its 55 W TDP and single-slot profile. For workloads that require the massive compute throughput, memory bandwidth, and tensor acceleration of the RTX 4090 D, the data supports that part without qualification. For low-power, compact, multi-display professional use, the W7400's specifications indicate a lighter-duty role, but the absence of benchmark scores prevents a performance-based verdict.

Architecture Differences

The two GPUs come from entirely different architectural generations and process nodes. The AMD Radeon PRO W7400 uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed Hotpink Bonefish, on a 6 nm TSMC process. The NVIDIA GeForce RTX 4090 D uses the AD102 chip built on Ada Lovelace architecture on a 5 nm TSMC process. The transistor counts differ dramatically: the AMD chip contains 13,300 million transistors on a 204 mm² die, while the NVIDIA chip contains 76,300 million transistors on a 609 mm² die. Transistor density for the AMD chip measures 65.2 million per mm², while the NVIDIA chip reaches 125.3 million per mm², reflecting the smaller process node.

The RDNA 3.0 architecture configures 1,792 shading units, 112 texture mapping units, and 64 raster output units. The Ada Lovelace architecture configures 14,592 shading units, 456 texture mapping units, and 176 raster output units. The RTX 4090 D also includes 456 tensor cores, a feature absent from the W7400's specification list, and 114 ray tracing cores compared to 28 for the AMD part. The NVIDIA card's FP16 performance matches its FP32 at 73.54 TFLOPS with a 1:1 ratio, and the AMD card likewise shows FP16 at 7.885 TFLOPS with a 1:1 ratio.

Clock behavior also differentiates the parts. The AMD card lists a base clock of 330 MHz and a boost clock of 1,100 MHz, with memory clocked at 1,350 MHz (10.8 Gbps effective). The NVIDIA card lists a base clock of 2,280 MHz and a boost clock of 2,520 MHz, with memory at 1,313 MHz (21 Gbps effective). The memory subsystems diverge in type as well: GDDR6 for AMD versus GDDR6X for NVIDIA, and bus widths of 128 bit versus 384 bit. The resulting bandwidth difference, 172.8 GB/s versus 1.01 TB/s, reflects the combined effect of memory type, bus width, and clock speed.

Where Each One Wins

The RTX 4090 D wins decisively in every compute category where specifications can be compared. Its FP32 throughput of 73.54 TFLOPS is approximately 9.3 times the W7400's 7.885 TFLOPS. Its texture rate of 1,149.1 GTexel/s is approximately 9.3 times the W7400's 123.2 GTexel/s. Its pixel rate of 443.5 GPixel/s is approximately 6.3 times the W7400's 70.40 GPixel/s. Memory bandwidth of 1.01 TB/s is approximately 5.8 times the W7400's 172.8 GB/s. The ray tracing core count of 114 versus 28 gives the NVIDIA part a substantial advantage in any ray-traced workload, and the 456 tensor cores provide dedicated acceleration for AI inference and training tasks that the AMD card lacks entirely.

The RTX 4090 D also offers three times the memory capacity at 24 GB versus 8 GB, with a faster memory type (GDDR6X versus GDDR6) and a wider bus (384 bit versus 128 bit). Its boost clock of 2,520 MHz far exceeds the W7400's 1,100 MHz boost. The NVIDIA card supports PCIe 4.0 x16, double the interface width of the AMD card's PCIe 4.0 x8. Its 1,599 USD launch MSRP, while substantial, positions it as the only one of the two with any recorded market valuation.

The Radeon PRO W7400 wins in power efficiency and physical footprint. Its 55 W TDP is roughly 13% of the RTX 4090 D's 425 W TDP. It requires no power connectors and a suggested PSU of only 250 W, compared to the NVIDIA card's 1x 16-pin connector and 800 W suggested PSU. The AMD card measures 168 mm in length versus 304 mm for the NVIDIA card, and occupies a single slot versus a triple slot. Its 4x DisplayPort 2.1 outputs exceed the RTX 4090 D's combination of 1x HDMI 2.1 and 3x DisplayPort 1.4a, and the newer DisplayPort standard offers higher bandwidth per output. For systems with limited space, limited power delivery, or multi-monitor professional setups, the W7400's specifications align better with those constraints.
