AMD Radeon Pro Duo vs AMD Radeon RX 5600M Comparison

Head-to-Head Benchmarks

The database contains one direct benchmark comparison between the AMD Radeon RX 5600M and the AMD Radeon Pro Duo: the Geekbench OpenCL test. The results are decisive. The RX 5600M scored 59,589, while the Radeon Pro Duo scored 35,860. That is a 66.2% advantage for the RX 5600M, a massive margin that underscores how far mobile GPU architecture has come since the Pro Duo's era.

In the broader benchmark context, the RX 5600M sits in the 85th percentile among all GPUs, with an average benchmark score of 46,601. Its nearest rivals in the database include the Intel Arc A530M (average score 46,614, a 0% delta), the AMD Radeon RX 6550M (46,702, -0.2%), the NVIDIA RTX A2000 (46,043, 1.2%), and the NVIDIA RTX 5880 Ada Generation (45,972, 1.4%). The RX 5600M is essentially neck-and-neck with these contemporaries, trailing the RX 6550M by a hair and leading the RTX A2000 by 1.2%. This places it in a tightly contested mid-range performance band.

The Radeon Pro Duo, by contrast, holds the 80th percentile with an average benchmark score of 35,860. Its nearest rivals are the NVIDIA Quadro GV100 (35,520, 1% ahead), the NVIDIA GeForce RTX 5070 Ti Mobile (35,435, 1.2% ahead), the NVIDIA T1000 (36,289, 1.2% behind), and the AMD Radeon RX 5300M (36,529, 1.8% behind). The Pro Duo is competitive within its own cohort, but that cohort sits roughly 23% below the RX 5600M's average score on a raw basis.

The single head-to-head result is consistent with the average scores. The RX 5600M wins the only shared test, and its overall database average (46,601) is substantially higher than the Pro Duo's (35,860). In OpenCL specifically, the RX 5600M's 59,589 score is not just a win, it is a dominant one. The Pro Duo's 35,860 falls well short, meaning that in compute workloads that rely on OpenCL, the newer mobile part is the clear choice.

It is notably the RX 5600M also has additional benchmark entries that the Pro Duo lacks: a 3DMark Steel Nomad DX12 score of 1,320, a Geekbench Metal score of 76,653, and a Geekbench Vulkan score of 48,843. These results are not directly comparable to the Pro Duo since the latter has no corresponding entries, but they indicate that the RX 5600M has a broader tested performance profile across multiple APIs.

Architecture Differences

The two GPUs come from fundamentally different eras of AMD design. The RX 5600M uses the Navi 10 chip built on RDNA 1.0 architecture, fabricated on a 7 nm process at TSMC. The Radeon Pro Duo uses the Capsaicin chip based on GCN 3.0 architecture, fabricated on a 28 nm process, also at TSMC. The process node gap is stark: 7 nm versus 28 nm, a difference that directly impacts transistor density and power efficiency.

Transistor counts tell a surprising story. The Navi 10 chip packs 10,300 million transistors into a 251 mm² die, yielding a transistor density of 41.0 million per mm². The Capsaicin chip contains 8,900 million transistors spread across a much larger 596 mm² die, resulting in a density of just 14.9 million per mm². The RX 5600M achieves nearly three times the transistor density of the Pro Duo, which explains how a smaller, lower-power part can outperform it in compute benchmarks.

Memory architecture differs fundamentally as well. The RX 5600M uses 6 GB of GDDR6 on a 192-bit bus, with 288.0 GB/s of bandwidth and a memory clock of 1500 MHz (12 Gbps effective). The Radeon Pro Duo uses 4 GB of HBM on a 4096-bit bus, with 512.0 GB/s of bandwidth and a memory clock of 500 MHz (1000 Mbps effective). The Pro Duo has the wider bus and higher bandwidth, a hallmark of its professional-grade HBM implementation, but the RX 5600M's GDDR6 is clocked much higher.

Shader and texture resources also differ. The RX 5600M has 2,304 shading units, 144 TMUs, and 64 ROPs. The Radeon Pro Duo has 4,096 shading units, 256 TMUs, and 64 ROPs. The Pro Duo has nearly double the shading units and TMUs, yet its pixel rate of 64.00 GPixel/s is lower than the RX 5600M's 80.96 GPixel/s. The texture rate tells a different story: the Pro Duo's 256.0 GTexel/s exceeds the RX 5600M's 182.2 GTexel/s.

API support is another differentiator. The RX 5600M supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The Radeon Pro Duo supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The RX 5600M has a higher DirectX feature level and a newer Vulkan version. Neither GPU includes ray tracing cores or tensor cores; both entries list null for those fields.

The Radeon Pro Duo's dual-GPU nature is implied by its "Capsaicin" chip and 596 mm² die, but the database does not list it as a dual-chip part explicitly. What is clear is that the Pro Duo is a professional workstation card with a 277 mm length, 111 mm height, dual-slot footprint, and 3x 8-pin power connectors. The RX 5600M is an integrated mobile part (IGP slot width) with no power connectors and portable-device-dependent display outputs.

Specification Differences

The RX 5600M and Radeon Pro Duo differ across nearly every specification field. The RX 5600M belongs to the Radeon RX 5000 series with a Navi Mobile (RX 5000M) generation, while the Pro Duo has no series listed and belongs to the Radeon Pro GCN generation. The RX 5600M uses a 7 nm process; the Pro Duo uses 28 nm. The RX 5600M has 10,300 million transistors on a 251 mm² die; the Pro Duo has 8,900 million on a 596 mm² die. Transistor density is 41.0M / mm² versus 14.9M / mm².

Clock speeds are only partially specified. The RX 5600M lists a base clock of 1035 MHz, boost clock of 1265 MHz, and game clock of 1190 MHz. The Pro Duo lists no base, boost, or game clocks. Memory clocks are 1500 MHz (12 Gbps effective) for the RX 5600M versus 500 MHz (1000 Mbps effective) for the Pro Duo. Memory capacity is 6 GB of GDDR6 versus 4 GB of HBM. Bus width is 192-bit versus 4096-bit, and bandwidth is 288.0 GB/s versus 512.0 GB/s.

Shading units are 2,304 versus 4,096; TMUs are 144 versus 256; ROPs are identical at 64. Pixel rate is 80.96 GPixel/s versus 64.00 GPixel/s. Texture rate is 182.2 GTexel/s versus 256.0 GTexel/s. FP32 performance is 5.829 TFLOPS versus 8.192 TFLOPS. FP16 performance is 11.66 TFLOPS (2:1) versus 8.192 TFLOPS (1:1). The RX 5600M has a 2:1 FP16 ratio, while the Pro Duo has a 1:1 ratio.

Power and physical specs diverge sharply. The RX 5600M has a TDP of 150 W, is an IGP slot width, and has no power connectors. The Pro Duo has a TDP of 350 W, is dual-slot, requires 3x 8-pin power connectors, and suggests a 750 W PSU. The RX 5600M uses PCIe 4.0 x16; the Pro Duo uses PCIe 3.0 x16. Display outputs are portable-device-dependent for the RX 5600M, while the Pro Duo offers 1x HDMI 1.4a and 3x DisplayPort 1.2. The Pro Duo is 277 mm long and 111 mm high; the RX 5600M has no listed dimensions.

Release dates are far apart. The RX 5600M launched on 2020-07-06, while the Pro Duo launched on 2016-04-25. The RX 5600M's predecessor is Polaris Mobile; the Pro Duo's predecessor is FirePro GCN. The Pro Duo has a listed successor, Radeon Pro Polaris, while the RX 5600M has none. The Pro Duo has a launch MSRP of 1,499 USD, while the RX 5600M has no listed launch MSRP. Both are end-of-life products.

The Verdict

The data points in one direction: the AMD Radeon RX 5600M is the better performer in the shared benchmark and has the higher overall database standing. Its 66.2% OpenCL win over the Radeon Pro Duo is the most direct evidence. The RX 5600M also holds the 85th percentile versus the Pro Duo's 80th, and its average benchmark score of 46,601 is substantially higher than the Pro Duo's 35,860.

For buyers choosing between these two, the RX 5600M is the rational pick for compute workloads that use OpenCL, DirectX, Metal, or Vulkan. It offers a newer architecture (RDNA 1.0 versus GCN 3.0), a much smaller and denser chip, a far lower TDP of 150 W versus 350 W, and a modern PCIe 4.0 interface. It also supports DirectX 12_1 versus 12_0 and Vulkan 1.4 versus 1.2.170. The RX 5600M is a mobile IGP part, so it suits portable systems; the Pro Duo is a dual-slot desktop card requiring 3x 8-pin connectors and a 750 W PSU.

The Radeon Pro Duo retains advantages in raw specifications: more shading units (4,096 versus 2,304), more TMUs (256 versus 144), higher FP32 throughput (8.192 TFLOPS versus 5.829 TFLOPS), higher texture rate (256.0 GTexel/s versus 182.2 GTexel/s), and higher memory bandwidth (512.0 GB/s versus 288.0 GB/s). It also has a wider 4096-bit memory bus and 4 GB of HBM. However, those theoretical advantages do not manifest in the one benchmark where both are measured. The Pro Duo's 64.00 GPixel/s pixel rate is also lower than the RX 5600M's 80.96 GPixel/s.

The Radeon Pro Duo is a legacy professional card with a 1,499 USD launch MSRP and a 2016 release date. The RX 5600M is a 2020 mobile part. If the workload is modern compute or gaming across multiple APIs, the RX 5600M is the clear winner based on recorded results. If the workload specifically requires the Pro Duo's HBM memory layout or dual-GPU-class raw FP32, the specifications suggest it, but the benchmark data does not support choosing it over the RX 5600M for general performance.

The verdict is straightforward: the RX 5600M wins on measured performance, efficiency, and API modernity. The Pro Duo is a historical artifact with high theoretical throughput but poor real-world showing in the tested workload. For anyone asking which card to pick from the database, the RX 5600M is the answer.
