AMD Radeon Pro Duo vs NVIDIA T600 Mobile Comparison

AMD Radeon Pro Duo and NVIDIA T600 Mobile occupy different ends of the hardware spectrum, yet their benchmark scores land surprisingly close. The AMD Radeon Pro Duo scores 35,860 in Geekbench OpenCL, while the NVIDIA T600 Mobile scores 35,486 in the same test. That is a delta of 1.1% in favor of AMD. However, the T600 Mobile also has a Geekbench Vulkan score of 30,211, which the Radeon Pro Duo lacks entirely. The AMD part sits at the 80th percentile among all GPUs, whereas the T600 Mobile sits at the 77th percentile. The Radeon Pro Duo’s average benchmark score is 35,860; the T600 Mobile’s average is 32,849, pulled down by its Vulkan result. In the head-to-head OpenCL comparison, the Radeon Pro Duo wins 1 test out of 1, with the T600 Mobile winning 0.

The Verdict

The data splits cleanly by workload type. If the task is OpenCL compute, the AMD Radeon Pro Duo edges out the NVIDIA T600 Mobile by 1.1%, scoring 35,860 against 35,486. That margin is small enough to be within run-to-run variance, but the AMD card also holds a higher overall percentile (80th vs. 77th), indicating broader competitiveness across the GPU landscape. For anyone prioritizing raw OpenCL throughput in a desktop workstation, the Radeon Pro Duo is the safer pick strictly from these numbers.

Conversely, the NVIDIA T600 Mobile offers a second benchmark dimension: its Geekbench Vulkan score of 30,211. The Radeon Pro Duo has no recorded Vulkan result, so the T600 Mobile is the only option here with validated Vulkan performance. Furthermore, the T600 Mobile draws only 40 W, compared to the Radeon Pro Duo’s 350 W, and requires no power connectors, while the Radeon Pro Duo needs three 8-pin connectors and a 750 W suggested PSU. The T600 Mobile is also an IGP form factor, meaning it fits into portable devices, whereas the Radeon Pro Duo is a dual-slot 277 mm card. For mobile or low-power systems, the T600 Mobile is the only feasible choice from this pair.

The verdict is straightforward: desktop OpenCL compute favors the AMD Radeon Pro Duo by a hair. Mobile or Vulkan-focused workloads favor the NVIDIA T600 Mobile, which also brings far lower power demands and physical flexibility. Neither card dominates the other across all metrics.

Architecture Differences

The AMD Radeon Pro Duo uses the Capsaicin chip with GCN 3.0 architecture, built on a 28 nm process at TSMC. It packs 8,900 million transistors on a 596 mm² die, yielding a transistor density of 14.9M per mm². The NVIDIA T600 Mobile uses the TU117 chip with Turing architecture, also fabricated by TSMC but on a 12 nm node. It contains 4,700 million transistors on a 200 mm² die, giving a density of 23.5M per mm². The AMD chip is larger and older, while the NVIDIA chip is denser and more modern in process node.

Memory architectures differ fundamentally. The Radeon Pro Duo uses 4 GB of HBM on a 4096-bit bus, delivering 512.0 GB/s of bandwidth. The T600 Mobile uses 4 GB of GDDR6 on a 128-bit bus, providing 192.0 GB/s. That is a 320 GB/s gap in favor of AMD, which is substantial for memory-bound workloads. The Radeon Pro Duo’s memory clock is listed at 500 MHz (1000 Mbps effective), while the T600 Mobile’s memory runs at 1500 MHz (12 Gbps effective). Higher effective speed on the NVIDIA part does not compensate for the narrower bus.

Compute resource counts also diverge sharply. The Radeon Pro Duo has 4,096 shading units, 256 TMUs, and 64 ROPs. The T600 Mobile has 896 shading units, 56 TMUs, and 32 ROPs. Pixel rate is 64.00 GPixel/s for AMD versus 45.12 GPixel/s for NVIDIA. Texture rate is 256.0 GTexel/s versus 78.96 GTexel/s. FP32 throughput is 8.192 TFLOPS for AMD versus 2.527 TFLOPS for NVIDIA. FP16 is also different: the Radeon Pro Duo achieves 8.192 TFLOPS (1:1 ratio), while the T600 Mobile reaches 5.053 TFLOPS with a 2:1 ratio. Both cards lack ray tracing and tensor cores.

API support shows the NVIDIA part ahead in some areas. Both support DirectX 12 and OpenGL 4.6. The Radeon Pro Duo lists Vulkan 1.2.170, while the T600 Mobile lists Vulkan 1.4. DirectX feature level differs: the Radeon Pro Duo is 12_0, the T600 Mobile is 12_1. Display outputs also differ: the Radeon Pro Duo has 1x HDMI 1.4a and 3x DisplayPort 1.2, while the T600 Mobile is marked as "Portable Device Dependent."

Head-to-Head Benchmarks

The only shared benchmark is Geekbench OpenCL. The AMD Radeon Pro Duo scores 35,860, and the NVIDIA T600 Mobile scores 35,486. The delta is 1.1%, with AMD as the winner. That difference equates to 374 points, which is minor in absolute terms but consistent with the Radeon Pro Duo’s higher shading unit count (4,096 vs. 896) and much larger memory bandwidth (512.0 GB/s vs. 192.0 GB/s). The T600 Mobile’s higher boost clock of 1410 MHz (versus no listed base or boost for AMD) does not close the gap in OpenCL.

The T600 Mobile has a second benchmark, Geekbench Vulkan, where it scores 30,211. This is lower than its own OpenCL score by 5,275 points, indicating that Vulkan performance is weaker on this Turing-based part. The Radeon Pro Duo has no Vulkan benchmark recorded, so no direct comparison exists. In terms of rival positioning, the Radeon Pro Duo’s nearest rival is the NVIDIA Quadro GV100 at 35,520 (1% behind), followed by the GeForce RTX 5070 Ti Mobile at 35,435 (1.2% behind). On the other side, the NVIDIA T1000 scores 36,289, which is 1.2% ahead of the Radeon Pro Duo. The AMD Radeon RX 5300M is 1.8% ahead at 36,529.

For the T600 Mobile, its nearest rival is the NVIDIA P104-100 at 32,982, which is 0.4% ahead. The AMD Radeon RX 590 GME scores 32,601 (0.8% behind), and the AMD FirePro S9300 X2 scores 32,540 (0.9% behind). The NVIDIA T550 Mobile scores 33,161, which is 0.9% ahead. These rival deltas show the T600 Mobile sitting in a tight cluster around the 33,000 OpenCL mark, while the Radeon Pro Duo sits in a higher cluster around 35,500–36,500.
