AMD Radeon PRO W7400 vs NVIDIA RTX PRO 5000 Blackwell Comparison

Where Each One Wins

The recorded data splits these two professional GPUs into completely different performance classes. The AMD Radeon PRO W7400 occupies the 50th percentile among all GPUs in the database, with an average benchmark score of zero, meaning no standardized benchmark entries exist for it. The NVIDIA RTX PRO 5000 Blackwell sits at the 98th percentile, with an average benchmark score of 182,109 across three recorded tests. This is not a close contest; the NVIDIA card outclasses the AMD card in nearly every measurable specification, and the benchmark data confirms the gap.

The AMD Radeon PRO W7400 wins in exactly one area that matters for certain workstation builds: power draw. It runs at a 55 W TDP with no power connectors required, and its suggested power supply is 250 W. The NVIDIA RTX PRO 5000 Blackwell demands 300 W, uses a single 16-pin connector, and suggests a 700 W power supply. For compact systems, low-noise builds, or environments with strict power budgets, the AMD card is the clear choice. It is also physically smaller: 168 mm long, 69 mm tall, and 20 mm wide, versus 267 mm, 111 mm, and 40 mm for the NVIDIA card. The AMD card is single-slot; the NVIDIA card is dual-slot.

The NVIDIA RTX PRO 5000 Blackwell wins everywhere else. Its 48 GB GDDR7 memory dwarfs the AMD card's 8 GB GDDR6. Its 384-bit memory bus delivers 1.34 TB/s of bandwidth, compared to 172.8 GB/s on a 128-bit bus. The NVIDIA card has 14,080 shading units, 440 texture mapping units, 160 raster operation units, 110 ray tracing cores, and 440 tensor cores. The AMD card has 1,792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores, with no tensor cores listed. The NVIDIA card's FP32 compute is 66.94 TFLOPS; the AMD card delivers 7.885 TFLOPS. FP16 is identical to FP32 on both cards at a 1:1 ratio.

Architecture Differences

The two cards come from fundamentally different design philosophies. The AMD Radeon PRO W7400 uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed "Hotpink Bonefish." It belongs to the Radeon Pro Navi generation, which the database labels as the Navi III Series. The chip is manufactured on a 6 nm process at TSMC, contains 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per square millimeter. The NVIDIA RTX PRO 5000 Blackwell is built on the GB202 chip using Blackwell 2.0 architecture, part of the Blackwell PRO W generation. It uses a 5 nm TSMC process, packs 92,200 million transistors onto a 750 mm² die, achieving a transistor density of 122.9 million per square millimeter. The NVIDIA die is nearly four times larger and holds almost seven times more transistors.

The memory architectures differ completely. The AMD card uses 8 GB of GDDR6 at 1,350 MHz with a 10.8 Gbps effective data rate, on a 128-bit bus. The NVIDIA card uses 48 GB of GDDR7 at 1,750 MHz with a 28 Gbps effective data rate, on a 384-bit bus. The bandwidth difference is enormous: 172.8 GB/s versus 1.34 TB/s, a factor of roughly 7.75.

Clock behavior also differs. The AMD card has a base clock of 330 MHz and a boost clock of 1,100 MHz, which are very low figures reflecting its power-efficient design. The NVIDIA card runs at a 1,740 MHz base clock and boosts to 2,377 MHz. The NVIDIA card's pixel rate is 380.3 GPixel/s versus 70.40 GPixel/s on the AMD card. Texture rates are 1,045.9 GTexel/s versus 123.2 GTexel/s.

Interface and output differences matter for workstation integration. The AMD card uses PCIe 4.0 x8; the NVIDIA card uses PCIe 5.0 x16. Both support four DisplayPort outputs, but the AMD card uses DisplayPort 2.1 while the NVIDIA card uses DisplayPort 2.1b. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card has 440 tensor cores, which the AMD card lacks entirely; this indicates the NVIDIA card is designed for AI and machine learning workloads, while the AMD card focuses on traditional graphics and compute.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two cards. The wins count is zero for both. However, the NVIDIA RTX PRO 5000 Blackwell has three recorded benchmark scores, and its nearest rivals provide context for interpreting those numbers.

In 3DMark Steel Nomad DX12, the NVIDIA card scores 9,579.5. This is a modern DirectX 12 ray-traced test, and the score places it comfortably in the high-end tier. In Geekbench OpenCL, it scores 254,116. In Geekbench Vulkan, it scores 282,631. The average benchmark score across these three tests is 182,109.

The nearest rivals in the database show where this card sits. The NVIDIA A100 SXM4 80 GB has an average score of 183,725, which is 0.9% lower than the RTX PRO 5000 Blackwell. The NVIDIA RTX 5000 Ada Generation scores 184,664, which is 1.4% lower. The NVIDIA GeForce RTX 4090 D scores 178,050, which is 2.3% higher than the RTX PRO 5000 Blackwell. The NVIDIA A100 SXM4 40 GB scores 187,147, which is 2.7% lower. So the RTX PRO 5000 Blackwell sits in a tight cluster with these four cards, all within roughly 3% of each other. It is essentially tied with the A100 80 GB and RTX 5000 Ada Generation, slightly ahead of the RTX 4090 D, and slightly behind the A100 40 GB.

The AMD Radeon PRO W7400 has no benchmark entries and no nearest rivals in the database. Its percentile rank of 50 places it at the median of all GPUs, but the absence of benchmark scores means the database cannot quantify its actual performance. The specification data suggests it operates in a much lower performance tier, with roughly one-tenth the FP32 compute of the NVIDIA card (7.885 TFLOPS versus 66.94 TFLOPS) and one-thirteenth the memory bandwidth.

Specification Differences

The Verdict

The specification data makes the performance hierarchy unambiguous. The NVIDIA RTX PRO 5000 Blackwell is a top-tier workstation GPU, ranked at the 98th percentile with an average benchmark score of 182,109. It trades within 3% of the NVIDIA A100 SXM4 80 GB, RTX 5000 Ada Generation, GeForce RTX 4090 D, and A100 SXM4 40 GB. Its 48 GB GDDR7 memory, 440 tensor cores, and 66.94 TFLOPS FP32 compute position it for large model inference, rendering, and compute workloads. The launch MSRP of 5,099 USD reflects its professional positioning.

The AMD Radeon PRO W7400 is a different kind of product. With a 55 W TDP, no power connectors, and a 250 W suggested PSU, it fits into systems where the NVIDIA card cannot operate. Its 168 mm length and single-slot profile allow installation in compact chassis. Its 8 GB memory and 7.885 TFLOPS compute are sufficient for lighter professional workloads, but the absence of tensor cores and the much smaller memory subsystem limit its range.

The choice depends entirely on the workload and the physical constraints of the system. For users who need large memory capacity, high compute throughput, or tensor core acceleration, the NVIDIA RTX PRO 5000 Blackwell is the only option between these two. For users constrained by power delivery, chassis space, or thermal limits, the AMD Radeon PRO W7400 offers a functional path forward. The data does not support any middle ground; these are two products at opposite ends of the professional GPU spectrum.
