Where Each One Wins

The recorded data shows a single head-to-head benchmark, and the NVIDIA GeForce RTX 4090 Mobile wins it outright. There are no benchmark tests in the database where the AMD Radeon Pro Duo comes out ahead. This is not a close contest in synthetic OpenCL compute: the RTX 4090 Mobile delivers 180,831 points versus 35,860 for the Radeon Pro Duo, a 404.3% advantage.

Beyond the direct comparison, the RTX 4090 Mobile has a broader benchmark profile. The database lists nine separate scores for it, spanning DirectX 9, 10, 11, 12, G2D, G3D, GPU compute, OpenCL, and Vulkan. The Radeon Pro Duo has only one recorded benchmark, Geekbench OpenCL. This means the NVIDIA card can be evaluated across a wider range of workloads, while the AMD card’s performance in other areas is simply not captured in the database.

In terms of relative standing, the RTX 4090 Mobile sits at the 84th percentile of all GPUs, with an average score of 43,667. Its nearest rivals include the NVIDIA Quadro M6000 (43,301, 0.8% lower), the GeForce RTX 5050 Mobile (43,268, 0.9% lower), the Quadro M6000 24 GB (43,262, 0.9% lower), and the RTX A6000 (44,075, 0.9% higher). The Radeon Pro Duo, at the 80th percentile with an average score of 35,860, sits near the Quadro GV100 (35,520, 1% lower), the GeForce RTX 5070 Ti Mobile (35,435, 1.2% lower), the T1000 (36,289, 1.2% higher), and the Radeon RX 5300M (36,529, 1.8% higher). The NVIDIA mobile part is clearly the stronger performer in the data set.

Architecture Differences

The two GPUs come from entirely different architectural generations. The RTX 4090 Mobile is built on Ada Lovelace, NVIDIA’s modern GPU architecture, using the AD103 chip. It is fabricated on a 5 nm process at TSMC, which is a significant manufacturing advantage. The transistor count is 45,900 million, packed into a die size of 379 mm², yielding a density of 121.1M transistors per mm².

The Radeon Pro Duo, in contrast, uses the Capsaicin chip based on GCN 3.0, an older AMD architecture. It is built on a 28 nm process, also at TSMC, with 8,900 million transistors on a much larger 596 mm² die. The transistor density is just 14.9M per mm², reflecting the older process node. This means the NVIDIA chip packs more than five times the transistors into a smaller physical area.

Memory architecture also differs sharply. The RTX 4090 Mobile uses 16 GB of GDDR6 on a 256-bit bus, achieving 576.0 GB/s. The Radeon Pro Duo uses 4 GB of HBM on a 4096-bit bus, achieving 512.0 GB/s. The AMD card’s bus width is sixteen times wider, but the effective memory speed is much lower, which is why the bandwidth ends up slightly below the NVIDIA part.

Feature support reflects the generational gap. The RTX 4090 Mobile has 76 RT cores and 304 tensor cores, enabling hardware-accelerated ray tracing and AI workloads. The Radeon Pro Duo has no RT cores and no tensor cores in the database. The NVIDIA card also supports DirectX 12 Ultimate (12_2), Vulkan 1.4, and OpenGL 4.6. The AMD card supports DirectX 12 (12_0), Vulkan 1.2.170, and OpenGL 4.6. The DirectX version difference is notable: 12_2 implies full feature support for ray tracing and mesh shaders, while 12_0 is the baseline.

Power and physical design diverge as well. The RTX 4090 Mobile is an integrated graphics package (IGP) with a 120 W TDP, no power connectors, and no slot width. The Radeon Pro Duo is a dual-slot card with a 350 W TDP, three 8-pin power connectors, and a suggested PSU of 750 W. The AMD card measures 277 mm in length and 111 mm in height. The NVIDIA part is portable-device dependent in terms of display outputs, while the AMD card offers 1x HDMI 1.4a and 3x DisplayPort 1.2.

Head-to-Head Benchmarks

The database contains exactly one head-to-head benchmark result between these two GPUs: Geekbench OpenCL. This test measures raw compute performance across a wide range of workloads, including integer and floating-point operations.

The NVIDIA GeForce RTX 4090 Mobile scores 180,831 in Geekbench OpenCL. The AMD Radeon Pro Duo scores 35,860. The delta is 404.3%, meaning the NVIDIA card outperforms the AMD card by a factor of roughly five. This is an overwhelming victory, and it aligns with the raw compute specifications. The RTX 4090 Mobile delivers 32.98 TFLOPS of FP32 performance, while the Radeon Pro Duo delivers 8.192 TFLOPS. The NVIDIA card is exactly four times higher in that metric, and the benchmark delta is consistent with that margin.

The RTX 4090 Mobile also has a massive advantage in shading units: 9,728 versus 4,096. Its pixel rate is 189.8 GPixel/s against 64.00 GPixel/s, and its texture rate is 515.3 GTexel/s against 256.0 GTexel/s. These numbers explain why the NVIDIA card dominates in the recorded compute benchmark.

There is no other benchmark in the database where the Radeon Pro Duo has a score. While the RTX 4090 Mobile has additional results, including 27,212 in Passmark G3D and 12,347 in Passmark GPU compute, those tests have no corresponding AMD result for comparison. The only direct measurement is the OpenCL test, and the outcome is unambiguous.

The nearest rival data for each card provides context for their respective standings. The RTX 4090 Mobile’s average score of 43,667 is close to the Quadro M6000 (43,301, 0.8% lower) and the RTX A6000 (44,075, 0.9% higher). The Radeon Pro Duo’s average of 35,860 is near the Quadro GV100 (35,520, 1% lower) and the T1000 (36,289, 1.2% higher). In both cases, the cards sit in a competitive cluster, but the clusters themselves are far apart. The NVIDIA part’s cluster is roughly 22% higher than the AMD part’s cluster in average score.

In summary, the head-to-head data shows a single, decisive result. The RTX 4090 Mobile wins the only overlapping benchmark by a wide margin, and its architecture, memory system, and compute resources all point in the same direction. The Radeon Pro Duo, while still a capable GPU in its own right, is outperformed by the modern NVIDIA part in the recorded measurements.
