AMD Radeon PRO W7900 vs NVIDIA RTX 4000 SFF Ada Generation Comparison

The NVIDIA RTX 4000 SFF Ada Generation and AMD Radeon PRO W7900 represent two divergent philosophies in professional graphics, and the benchmark data reveals a stark split between compute and graphics workloads. In the Geekbench OpenCL test, the NVIDIA card posts a score of 124,812 against AMD's 84,379, a decisive 47.9% advantage. However, the tables turn completely in Geekbench Vulkan, where AMD's 137,070 score eclipses NVIDIA's 109,364 by 20.2%. This one-win-a-piece outcome underscores that neither card is universally superior; the right choice depends entirely on the software stack and API in question.

Head-to-Head Benchmarks

The most striking disparity appears in OpenCL compute performance. NVIDIA's RTX 4000 SFF Ada Generation achieves 124,812 points, which is 47.9% higher than the Radeon PRO W7900's 84,379. This is a massive margin, indicating that for OpenCL-accelerated tasks—common in scientific computing, rendering, and certain simulation workloads—the NVIDIA card is the clear performer. The data shows NVIDIA leading by nearly half its own score, which is a dominant position. For context, the RTX 4000 SFF Ada's average benchmark score of 117,088 places it at the 95th percentile of all GPUs, while the Radeon PRO W7900 sits at the 94th percentile with an average of 110,725. The NVIDIA card also holds a 2.4% delta over the Tesla V100 SXM2 16 GB (114,395) and a 2.8% lead over the RTX A5500 Mobile (113,944), whereas the Radeon PRO W7900 trails the same Tesla V100 by 3.2% and the RTX A5500 Mobile by 2.8%.

The Vulkan results invert the narrative entirely. The Radeon PRO W7900 scores 137,070, beating the RTX 4000 SFF Ada's 109,364 by 20.2%. This is a substantial win for AMD in a modern graphics API that underpins many current game engines, CAD viewports, and real-time visualization tools. Vulkan's lower overhead and explicit control favor the Radeon's architecture here. The delta between the two cards in Vulkan (20.2%) is less than half the delta seen in OpenCL (47.9%), but it is still a decisive victory for AMD. Notably, the RTX 4000 SFF Ada's Vulkan score is actually lower than its own OpenCL score (109,364 vs 124,812), while the Radeon PRO W7900 shows the opposite trend, with Vulkan performance significantly exceeding its OpenCL result (137,070 vs 84,379). This suggests the AMD card is far more optimized for Vulkan's execution model, while NVIDIA's strengths lie in OpenCL's compute-centric workloads.

Looking at the nearest rivals provides additional context. The RTX 4000 SFF Ada's average score of 117,088 is just 0.3% below the NVIDIA GB10 (117,393) and 1.6% below the AMD Radeon PRO W7700 (118,976). These are extremely tight margins, implying the RTX 4000 SFF Ada is positioned among a cluster of similarly performing GPUs. On the AMD side, the Radeon PRO W7900's average of 110,725 is 1.0% above the Radeon Pro Vega II (109,617) and 3.2% above the Radeon Pro W6600X (107,342). The Radeon PRO W7900's average is notably lower than the RTX 4000 SFF Ada's, despite its Vulkan advantage, because the OpenCL deficit drags its aggregate score down.

The Verdict

From the data, the choice is clear: pick the NVIDIA RTX 4000 SFF Ada Generation if your primary workloads are OpenCL-based or require the highest possible compute throughput per watt. Its 47.9% OpenCL lead is the single largest performance gap in this comparison, and its 70 W TDP (versus AMD's 295 W) makes it an exceptionally efficient option for dense, multi-GPU configurations or space-constrained systems. The card's dual-slot, 168 mm length (6.6 inches) and lack of power connectors further cement its suitability for SFF builds. Its 95th percentile ranking and 2.4% lead over the Tesla V100 in average score reinforce its compute credentials.

Conversely, the AMD Radeon PRO W7900 is the pick for Vulkan-centric applications and tasks that demand massive memory capacity. Its 48 GB of GDDR6 (versus NVIDIA's 20 GB) and 864.0 GB/s bandwidth (versus 280.0 GB/s) provide a 3.08x memory bandwidth advantage and 2.4x capacity advantage, which are critical for large datasets, high-resolution textures, and complex scenes that exceed 20 GB. The 20.2% Vulkan win shows AMD's strength in modern graphics APIs. However, the launch MSRP of 3,999 USD for the Radeon PRO W7900 is a significant factor, though the RTX 4000 SFF Ada has no listed launch MSRP. If raw Vulkan performance and memory headroom are non-negotiable, the Radeon PRO W7900 wins. If efficiency and OpenCL compute dominate, the RTX 4000 SFF Ada is the data-backed choice.

Where Each One Wins

The NVIDIA RTX 4000 SFF Ada Generation wins decisively in OpenCL compute tasks. The 47.9% delta in this benchmark suggests it is better suited for scientific simulation, machine learning inference, and rendering engines that rely on OpenCL. Its 19.17 TFLOPS FP32 and FP16 (1:1) performance, while lower than AMD's 61.32 TFLOPS, is delivered at a fraction of the power (70 W vs 295 W). The card also features 48 RT cores and 192 tensor cores, enabling hardware-accelerated ray tracing and AI workloads, though the data does not include specific RT benchmarks. Its 280.0 GB/s bandwidth and 160-bit bus are modest, but the 20 GB frame buffer is sufficient for many professional tasks. The card's 95th percentile ranking and average score of 117,088 place it above the Radeon PRO W7900's 110,725, indicating broader overall compute strength across the aggregated benchmark.

The AMD Radeon PRO W7900 wins in Vulkan graphics and memory-intensive scenarios. Its 137,070 Vulkan score is 25.3% higher than its OpenCL score, showing a clear architectural bias toward this API. The 48 GB memory pool and 864.0 GB/s bandwidth are the largest in this comparison, and the 384-bit bus width (versus 160-bit) allows for massive data throughput. The card's 96 RT cores double NVIDIA's count, and its 479.0 GPixel/s pixel rate and 958.1 GTexel/s texture rate dwarf NVIDIA's 99.84 GPixel/s and 299.5 GTexel/s, respectively. For real-time rendering, high-resolution viewports, and Vulkan-based game engines, the Radeon PRO W7900 is the superior choice. Its triple-slot design and 280 mm length (11 inches) indicate a larger physical footprint, but that is the trade-off for its performance class.

Architecture Differences

The architectural divide is stark. The NVIDIA RTX 4000 SFF Ada Generation uses the AD104 chip built on TSMC's 5 nm process, containing 35,800 million transistors on a 294 mm² die, yielding a transistor density of 121.8M per mm². Its Ada Lovelace architecture is the successor to Workstation Ampere and the predecessor to Blackwell PRO W. It operates with a base clock of 720 MHz and a boost clock of 1560 MHz, with memory clocked at 1750 MHz (14 Gbps effective). The card has 6144 shading units, 192 TMUs, 64 ROPs, 48 RT cores, and 192 tensor cores, delivering 19.17 TFLOPS FP32 and FP16 (1:1). Its 160-bit memory bus connects to 20 GB of GDDR6.

The AMD Radeon PRO W7900 is built on the Navi 31 chip (codenamed Plum Bonito) using the same TSMC 5 nm process, but packs 57,700 million transistors on a 529 mm² die, resulting in a lower density of 109.1M per mm². Its RDNA 3.0 architecture follows Radeon Pro Vega and has no listed successor. Clocks are substantially higher: 1760 MHz base and 2495 MHz boost, with memory at 2250 MHz (18 Gbps effective). The card features 6144 shading units (same as NVIDIA), but doubles the TMUs to 384 and triples the ROPs to 192. It has 96 RT cores and no tensor cores, producing 61.32 TFLOPS FP32 and FP16 (1:1). The 384-bit bus supports 48 GB of GDDR6. Physically, the AMD card is a triple-slot design measuring 280 mm by 110 mm by 51 mm, requiring two 8-pin power connectors and a 600 W suggested PSU, while the NVIDIA card is dual-slot at 168 mm by 69 mm, uses no power connectors, and needs only a 250 W PSU. Both use PCIe 4.0 x16. Display outputs differ: NVIDIA offers four mini-DisplayPort 1.4a, while AMD provides three DisplayPort 2.1 and one mini-DisplayPort 2.1.
