AMD Radeon PRO W7900 vs NVIDIA RTX PRO 5000 Blackwell Comparison

Where Each One Wins

The benchmark data presents a clear asymmetry between these two workstation GPUs. The NVIDIA RTX PRO 5000 Blackwell wins both recorded head-to-head tests, and the margins are substantial. In Geekbench OpenCL, the NVIDIA card scores 254,116 against AMD's 84,379, a 201.2% advantage. In Geekbench Vulkan, the gap narrows somewhat but remains decisive: 282,631 versus 137,070, a 106.2% lead. These are not marginal victories; they represent a doubling of performance in one API and a tripling in the other.

The use-case split is therefore less about "which card wins which workload" and more about "how much does each card win by." The RTX PRO 5000 Blackwell dominates compute-oriented OpenCL workloads with a 201.2% delta, suggesting it is the stronger choice for general-purpose GPU compute tasks that leverage this API. The Vulkan result, while still a clear NVIDIA win, shows a smaller relative gap, indicating that AMD's architecture is comparatively less disadvantaged in graphics-centric or cross-platform rendering workloads.

The AMD Radeon PRO W7900 does not win any of the recorded head-to-head tests. Its average benchmark score of 110,725 places it at the 94th percentile of all GPUs, which is respectable, but the RTX PRO 5000 Blackwell sits at the 98th percentile with an average score of 182,109. The data suggests that for users whose software stack relies heavily on OpenCL compute, the NVIDIA card is in a different performance class entirely. For Vulkan-based workloads, the AMD card is more competitive but still trails by over 100%.

Architecture Differences

The architectural gap between these two cards is significant and explains much of the performance delta. The NVIDIA RTX PRO 5000 Blackwell uses the GB202 chip built on Blackwell 2.0 architecture, manufactured on a 5 nm process at TSMC. It packs 92,200 million transistors on a 750 mm² die, yielding a transistor density of 122.9 million per mm². The AMD Radeon PRO W7900 uses the Navi 31 chip with RDNA 3.0 architecture, codenamed Plum Bonito, also on TSMC's 5 nm node. However, it contains only 57,700 million transistors across a 529 mm² die, for a density of 109.1 million per mm².

The NVIDIA card's transistor advantage translates directly into a much larger compute configuration. It features 14,080 shading units, 440 texture mapping units, and 160 ROPs. The AMD card counters with 6,144 shading units, 384 TMUs, and 192 ROPs. Interestingly, AMD has more ROPs (192 versus 160), which contributes to its higher pixel rate of 479.0 GPixel/s compared to NVIDIA's 380.3 GPixel/s. However, NVIDIA's texture rate of 1,045.9 GTexel/s edges out AMD's 958.1 GTexel/s.

The memory subsystems also differ substantially. Both cards have 48 GB of memory on a 384-bit bus, but NVIDIA uses GDDR7 at 1750 MHz (28 Gbps effective), delivering 1.34 TB/s of bandwidth. AMD uses GDDR6 at 2250 MHz (18 Gbps effective), providing 864.0 GB/s. That is a 55% bandwidth advantage for NVIDIA, which matters greatly in memory-bound workstation tasks. NVIDIA also includes 440 tensor cores and 110 RT cores, while AMD's card lists 96 RT cores and no tensor core equivalent in the database.

Clock speeds tell a different story. AMD runs higher: 1760 MHz base and 2495 MHz boost versus NVIDIA's 1740 MHz base and 2377 MHz boost. Despite this, NVIDIA's FP32 throughput of 66.94 TFLOPS slightly exceeds AMD's 61.32 TFLOPS. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card uses PCIe 5.0 x16 while AMD uses PCIe 4.0 x16, a generational difference that could matter for data transfer in some workflows.

The Verdict

The recorded data points to a straightforward conclusion: the NVIDIA RTX PRO 5000 Blackwell is the superior performer in the benchmark suite. Its average score of 182,109 places it 64.5% higher than AMD's 110,725. The NVIDIA card also holds a higher percentile ranking at 98 versus AMD's 94. In direct head-to-head comparisons, NVIDIA wins both tests, with the OpenCL gap being particularly extreme at 201.2%.

Who should pick the AMD Radeon PRO W7900? Based strictly on the data, the case is difficult to make on pure performance grounds. The card is still an active product and performs at the 94th percentile, which is not weak by any means. Its nearest rivals include the NVIDIA RTX A5500 Mobile (2.8% higher average score) and the Tesla V100 SXM2 16 GB (3.2% higher). It sits 3.2% above the Radeon Pro W6600X. But against the RTX PRO 5000 Blackwell, it loses by 64.5% on average score and 201.2% in OpenCL. The AMD card does have a higher pixel rate (479.0 versus 380.3 GPixel/s), which suggests it could be better for certain rasterization-heavy tasks, but the benchmark suite does not include tests that would confirm this.

The NVIDIA card is the data-backed choice for anyone whose workloads align with the recorded benchmarks. It wins on raw compute, memory bandwidth, and API performance. The 1.34 TB/s memory bandwidth versus 864.0 GB/s is a massive differentiator. The 440 tensor cores also provide AI acceleration capabilities that AMD's card lacks entirely, which is notable for any machine learning or neural network workloads.

Head-to-Head Benchmarks

The two recorded head-to-head tests paint a definitive picture. In Geekbench OpenCL, the NVIDIA RTX PRO 5000 Blackwell scores 254,116 against the AMD Radeon PRO W7900's 84,379. That is a delta of 201.2%, meaning NVIDIA more than triples AMD's score. This result is particularly striking given that both cards have 48 GB of memory and similar FP32 throughput figures (66.94 TFLOPS versus 61.32 TFLOPS). The huge gap likely stems from NVIDIA's 440 tensor cores, its 1.34 TB/s memory bandwidth, and its substantially larger shading unit count of 14,080 versus 6,144.

The Geekbench Vulkan test shows a closer comparison but still favors NVIDIA decisively. NVIDIA scores 282,631, which is 106.2% higher than AMD's 137,070. This 2.06x advantage indicates that even in a graphics API where AMD's higher pixel rate (479.0 GPixel/s) could theoretically help, the NVIDIA card's overall architecture wins out. The Vulkan delta of 106.2% is roughly half the OpenCL delta, which suggests AMD's RDNA 3.0 architecture is relatively more competitive in graphics-oriented tasks than in pure compute.

Looking at the broader competitive context, the NVIDIA card's nearest rivals include the NVIDIA A100 SXM4 80 GB (0.9% lower average score), the RTX 5000 Ada Generation (1.4% lower), and the GeForce RTX 4090 D (2.3% higher). The AMD card's nearest rivals are less impressive: the Radeon Pro Vega II (1% lower), the RTX A5500 Mobile (2.8% higher), and the Radeon Pro W6600X (3.2% lower). This positioning reinforces that the RTX PRO 5000 Blackwell competes at the top tier of GPU performance, while the Radeon PRO W7900 sits in a mid-to-high tier.

Specification Differences

The specification table reveals where the two cards diverge. On the compute side, NVIDIA leads with 14,080 shading units, 440 TMUs, 110 RT cores, and 440 tensor cores. AMD has 6,144 shading units, 384 TMUs, 96 RT cores, and no tensor cores. The ROP count favors AMD at 192 versus NVIDIA's 160. Clock speeds favor AMD as well: 1760 MHz base and 2495 MHz boost for AMD versus 1740 MHz base and 2377 MHz boost for NVIDIA.

Memory configuration is identical in capacity and bus width (48 GB, 384-bit), but the type and speed differ. NVIDIA uses GDDR7 at 1750 MHz with 28 Gbps effective speed, achieving 1.34 TB/s. AMD uses GDDR6 at 2250 MHz with 18 Gbps effective speed, achieving 864.0 GB/s. The bandwidth difference of roughly 476 GB/s is one of the largest specification gaps between the two.

Power and physical characteristics also differ. The NVIDIA card has a 300 W TDP with a 700 W suggested PSU and uses a single 16-pin connector. The AMD card has a 295 W TDP with a 600 W suggested PSU and uses two 8-pin connectors. NVIDIA is dual-slot while AMD is triple-slot. NVIDIA measures 267 mm in length, 111 mm in height, and 40 mm in width, while AMD measures 280 mm, 110 mm, and 51 mm respectively. The AMD card is noticeably larger in volume.

The bus interface differs: NVIDIA uses PCIe 5.0 x16 while AMD uses PCIe 4.0 x16. Display outputs also vary: NVIDIA provides 4x DisplayPort 2.1b, while AMD offers 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1. The NVIDIA card was released on 2025-03-17, while the AMD card came out on 2023-05-25. The process node is the same (5 nm TSMC), but the transistor counts differ substantially: 92,200 million for NVIDIA versus 57,700 million for AMD, on die sizes of 750 mm² and 529 mm² respectively.
