The Radeon Pro Duo sits right in the middle of this group, indicating that its performance level is roughly comparable to these mid-range and older workstation parts, not to the modern flagship mobile GPU.

Architecture Differences

The architectural gap between these two GPUs is as wide as the benchmark gap. The NVIDIA GeForce RTX 5090 Mobile is built on the GB203 chip using the Blackwell 2.0 architecture, manufactured on a 5 nm process at TSMC. It packs 45,600 million transistors into a 378 mm² die, yielding a transistor density of 120.6 million per mm². The Radeon Pro Duo uses the Capsaicin chip with the GCN 3.0 architecture, built on a much older 28 nm process, also at TSMC. It contains only 8,900 million transistors spread across a larger 596 mm² die, resulting in a density of just 14.9 million per mm². This process and design difference explains a substantial portion of the performance disparity; the newer node allows for far greater complexity and efficiency.

Core configurations differ enormously. The RTX 5090 Mobile features 10,496 shading units, 328 texture mapping units, and 112 ROPs. It also includes 82 RT cores and 328 tensor cores, enabling hardware-accelerated ray tracing and AI features. The Radeon Pro Duo has 4,096 shading units, 256 TMUs, and 64 ROPs, with no dedicated RT or tensor cores listed. This means the NVIDIA part has more than double the shader count and significantly higher pixel and texture throughput. The RTX 5090 Mobile achieves a pixel rate of 169.7 GPixel/s and a texture rate of 496.9 GTexel/s, while the Radeon Pro Duo manages only 64.00 GPixel/s and 256.0 GTexel/s respectively. Compute throughput shows a similar story: the RTX 5090 Mobile delivers 31.80 TFLOPS for both FP32 and FP16, whereas the Radeon Pro Duo provides just 8.192 TFLOPS for the same precisions.

Memory subsystems are also generations apart. The RTX 5090 Mobile uses 24 GB of GDDR7 memory on a 256-bit bus, producing a bandwidth of 896.0 GB/s. The Radeon Pro Duo uses 4 GB of HBM memory on a massive 4096-bit bus, which yields 512.0 GB/s of bandwidth. While the older card has a wider interface, it is hamstrung by far less capacity and lower effective memory clocks. The RTX 5090 Mobile also supports the latest APIs, including DirectX 12 Ultimate (12_2), Vulkan 1.4, and OpenGL 4.6. The Radeon Pro Duo supports DirectX 12 (12_0), Vulkan 1.2.170, and OpenGL 4.6, lacking the feature set of the newer DirectX version.

The Verdict

The data leads to an unambiguous conclusion: the NVIDIA GeForce RTX 5090 Mobile is the superior GPU by every measurable metric in the database. Its Geekbench OpenCL score of 201,834 is more than five times that of the Radeon Pro Duo's 35,860. Its average benchmark score of 45,152 places it in the 84th percentile of all GPUs, while the Radeon Pro Duo sits at the 80th percentile. Even though the percentile ranks are close, the actual scores reveal a massive gulf in capability.

For any user prioritizing raw compute performance, modern API support, or energy efficiency, the RTX 5090 Mobile is the clear choice. It operates at a TDP of 95 W compared to the Radeon Pro Duo's 350 W, making it dramatically more power-efficient while delivering far higher performance. The NVIDIA part is also an active production product with a 2025 release date, whereas the AMD card is end-of-life, having launched in 2016. The Radeon Pro Duo was released with a launch MSRP of 1,499 USD, but its age and architectural limitations mean it cannot compete with the modern mobile flagship. The verdict is straightforward: the RTX 5090 Mobile wins decisively, and the Radeon Pro Duo is only relevant for legacy systems or applications that specifically require its unique dual-GPU HBM design.

Specification Differences

The two GPUs differ across nearly every specification field. The most striking differences are in process node, transistor count, and memory capacity. The RTX 5090 Mobile is fabricated on a 5 nm process with 45,600 million transistors, while the Radeon Pro Duo uses a 28 nm process with 8,900 million transistors. The NVIDIA chip has a smaller die at 378 mm² versus 596 mm², and a much higher transistor density of 120.6M / mm² compared to 14.9M / mm².

Memory specifications diverge completely. The RTX 5090 Mobile offers 24 GB of GDDR7 on a 256-bit bus, with 896.0 GB/s bandwidth. The Radeon Pro Duo has 4 GB of HBM on a 4096-bit bus, with 512.0 GB/s bandwidth. Clock speeds also differ: the RTX 5090 Mobile has a base clock of 990 MHz and a boost clock of 1515 MHz, with memory at 1750 MHz (28 Gbps effective). The Radeon Pro Duo has no base or boost clock listed, and its memory runs at 500 MHz (1000 Mbps effective).

The AMD Radeon Pro Duo has no recorded benchmark wins against the RTX 5090 Mobile. Its only advantage appears in the specification sheet, where it has a wider memory bus at 4096-bit, but that does not translate into higher bandwidth or better performance. Its dual-slot design and 3x 8-pin power connectors suggest it was built for desktop workstations, but the data shows it cannot match the mobile NVIDIA part in any compute task.

For use cases, the RTX 5090 Mobile is the obvious pick for any modern workload, including ray-traced gaming, AI inference, and high-resolution content creation. Its high FP32 and FP16 throughput of 31.80 TFLOPS makes it suitable for general compute and machine learning tasks. The Radeon Pro Duo, with its 8.192 TFLOPS and older GCN architecture, is only relevant for legacy software that was optimized for that specific design, or for systems that require its unique HBM memory configuration. In any head-to-head comparison, the RTX 5090 Mobile is the clear winner, and the Radeon Pro Duo's place in the database is as a historical artifact rather than a competitive product.
