AMD Radeon Pro 570 vs AMD Radeon Pro Duo Comparison

# AMD Radeon Pro Duo vs AMD Radeon Pro 570

The AMD Radeon Pro Duo and AMD Radeon Pro 570 are two very different answers to the same question: how much compute can you pack into a professional GPU? The Duo is a dual-GPU monster from the GCN 3.0 era, while the 570 is a single-chip, power-efficient part built for Apple's Mac ecosystem. The benchmark data reveals a clear hierarchy, but the story is more nuanced than a simple score comparison.

Head-to-Head Benchmarks

The only direct benchmark comparison available is Geekbench OpenCL, and it delivers a decisive result. The AMD Radeon Pro Duo scores 35,860, while the AMD Radeon Pro 570 scores 27,702. That is a 29.4% advantage for the Duo. In raw compute terms, this is a substantial gap — the Duo is nearly a third faster in this general-purpose GPU compute test.

Context matters here. The Duo's OpenCL score places it at the 80th percentile of all GPUs, while the 570 sits at the 78th percentile. Despite the 29.4% head-to-head gap, their overall standings are only two percentile points apart. This suggests that the 570 is already a strong performer in the broader GPU landscape, and the Duo is simply a step above. Look at the nearest rivals for each card: the Duo trades blows with the NVIDIA Quadro GV100 (35,520, just 1% behind) and the NVIDIA T1000 (36,289, 1.2% ahead of the Duo). Meanwhile, the 570 is essentially tied with the NVIDIA GeForce RTX 3050 Mobile (33,170, only 0.1% behind) and the NVIDIA T550 Mobile (33,161, 0.1% behind). The Duo is competing in a higher weight class entirely.

The 570's other benchmark results are telling. Its Geekbench Metal score is 39,945, which is its strongest showing, and its Vulkan score is 31,974. The OpenCL score is the lowest of the three. This indicates that the 570's performance varies significantly depending on the API, and that its OpenCL showing may not fully represent its capabilities in Metal-optimized workloads. The Duo has no Metal or Vulkan scores listed, so we cannot make a cross-API comparison. But the data we do have — the OpenCL head-to-head — is unambiguous: the Duo wins, and it wins by a wide margin.

Architecture Differences

The two cards are built on different generations of AMD's Graphics Core Next architecture. The Radeon Pro Duo uses GCN 3.0, with a chip codenamed "Capsaicin." The Radeon Pro 570 uses GCN 4.0, with a chip codenamed "Ellesmere." This is a generational jump, and it shows in the manufacturing process. The Duo is fabricated on a 28 nm process at TSMC, while the 570 uses a 14 nm process at GlobalFoundries. The smaller node gives the 570 a significant efficiency advantage.

The transistor counts tell the story of two very different designs. The Duo packs 8,900 million transistors onto a 596 mm² die, resulting in a transistor density of 14.9 million per square millimeter. The 570 has 5,700 million transistors on a 232 mm² die, with a much higher density of 24.6 million per square millimeter. The Duo is a massive, power-hungry chip — or rather, it is a single package containing two GPU dies, which explains its size. The 570 is a single, compact die.

Memory configurations also diverge sharply. The Duo uses 4 GB of HBM memory with a 4096-bit bus, delivering 512.0 GB/s of bandwidth. The 570 uses 4 GB of GDDR5 memory on a 256-bit bus, with 217.0 GB/s of bandwidth. The Duo's memory bandwidth is more than double that of the 570. This is a critical difference for compute workloads that are memory-bound. The Duo's memory clock is listed as 500 MHz (1000 Mbps effective), while the 570's memory runs at 1695 MHz (6.8 Gbps effective). The higher clock on the 570 cannot compensate for the much narrower bus.

Compute resources follow the same pattern. The Duo has 4096 shading units, 256 TMUs, and 64 ROPs. The 570 has 1792 shading units, 112 TMUs, and 32 ROPs. The Duo has more than double the shading units and TMUs, and exactly double the ROPs. Pixel rate is 64.00 GPixel/s for the Duo versus 35.36 GPixel/s for the 570. Texture rate is 256.0 GTexel/s versus 123.8 GTexel/s. FP32 performance is 8.192 TFLOPS for the Duo versus 3.960 TFLOPS for the 570. Both cards offer FP16 at a 1:1 ratio with FP32, meaning the Duo delivers 8.192 TFLOPS FP16 and the 570 delivers 3.960 TFLOPS FP16.

Power consumption is where the 570 strikes back. The Duo has a TDP of 350 W, requires three 8-pin power connectors, and needs a 750 W suggested power supply. The 570 has a TDP of 150 W, requires no power connectors, and has no suggested PSU listed because it is an integrated graphics processor (IGP) for portable devices. The 570 is a dual-slot card? No — the 570 is listed as "IGP" slot width, while the Duo is dual-slot. The Duo is a 277 mm long card, while the 570 has no listed dimensions. The Duo also has a 10.9 inch length, 4.4 inch height, and explicit display outputs (1x HDMI 1.4a, 3x DisplayPort 1.2). The 570's display outputs are "Portable Device Dependent."

The Verdict

The data points to a simple conclusion for raw compute performance: the AMD Radeon Pro Duo is the stronger card. Its 29.4% OpenCL lead over the 570 is decisive, and its 80th percentile ranking versus the 570's 78th percentile confirms it sits higher in the overall GPU hierarchy. The Duo's 8.192 TFLOPS FP32 performance is more than double the 570's 3.960 TFLOPS, and its 512.0 GB/s memory bandwidth is more than double the 570's 217.0 GB/s. For any workload that scales with compute throughput or memory bandwidth, the Duo is the clear choice.

But the 570 is not without its own strengths. Its 14 nm process node, lower 150 W TDP, and lack of external power connectors make it a far more practical solution for portable or integrated systems. Its Vulkan 1.3 support is newer than the Duo's Vulkan 1.2.170. And its Geekbench Metal score of 39,945 suggests that in Metal-optimized environments, it may punch above its OpenCL weight. The 570's release date of June 2017 also makes it a newer design.

The launch MSRP of the Duo is 1,499 USD, which reflects its dual-GPU, high-bandwidth design. The 570 has no listed MSRP, which is consistent with its role as an integrated part of Apple's Mac systems rather than a standalone retail product.

Where Each One Wins

AMD Radeon Pro Duo wins in:

• OpenCL compute performance (35,860 vs 27,702, 29.4% faster)
• Overall GPU percentile ranking (80th vs 78th)
• Shading units (4096 vs 1792) and TMUs (256 vs 112)
• Memory bandwidth (512.0 GB/s vs 217.0 GB/s) and bus width (4096-bit vs 256-bit)
• Pixel rate (64.00 GPixel/s vs 35.36 GPixel/s) and texture rate (256.0 GTexel/s vs 123.8 GTexel/s)
• FP32 and FP16 compute (8.192 TFLOPS vs 3.960 TFLOPS for both)

AMD Radeon Pro 570 wins in:

• Power efficiency (150 W TDP vs 350 W TDP)
• Manufacturing process (14 nm vs 28 nm) and transistor density (24.6M / mm² vs 14.9M / mm²)

The choice depends on the use case. If you need maximum compute throughput in a workstation with ample power and cooling, the Duo is the data-backed winner. If you need a low-power, integrated solution for a portable system and can leverage Metal or Vulkan workloads, the 570 offers a compelling profile. The Duo is a heavyweight champion; the 570 is a lightweight contender with modern efficiency.
