AMD Radeon Pro Duo vs AMD Radeon RX 6700 Comparison

Head-to-Head Benchmarks

The only directly comparable benchmark in the database is Geekbench OpenCL, and the result is decisive. The AMD Radeon RX 6700 scores 97,841, while the AMD Radeon Pro Duo scores 35,860. That is a delta of -63.3% for the Pro Duo, meaning the RX 6700 outperforms it by a massive margin in this compute workload. The RX 6700 does not merely win; it nearly triples the older card's output.

Looking at the broader database context, the RX 6700's OpenCL score places it in the 75th percentile of all GPUs. Its nearest rivals include the NVIDIA CMP 70HX (score 30,476, delta -0.1%), the NVIDIA Tesla M60 (score 30,490, delta -0.2%), and the AMD Radeon RX 6800 (score 30,095, delta 1.1%). The RX 6700 sits just ahead of these cards in average benchmark score, with a 1.6% lead over the NVIDIA GeForce RTX 3070 Ti (score 29,945). This suggests the RX 6700 is a solid mid-to-high tier performer in the overall GPU landscape.

The Radeon Pro Duo, by contrast, has an average benchmark score of 35,860, which puts it in the 80th percentile of all GPUs. Its nearest rivals are the NVIDIA Quadro GV100 (score 35,520, delta 1%), the NVIDIA GeForce RTX 5070 Ti Mobile (score 35,435, delta 1.2%), and the NVIDIA T1000 (score 36,289, delta -1.2%). Notably, the Pro Duo is actually slightly slower than the T1000, a professional entry-level card. The Pro Duo's OpenCL score is its only recorded benchmark, so its percentile ranking is based on a single data point. However, the head-to-head result is unambiguous: the RX 6700 wins the only shared test, and wins it emphatically.

Where Each One Wins

The RX 6700 wins the only direct comparison, but the database also contains additional benchmarks for the RX 6700 that the Pro Duo lacks. These results illustrate where the RX 6700 excels across different API and workload types, even if a direct head-to-head is unavailable.

In Geekbench Vulkan, the RX 6700 scores 83,974, and in Geekbench Metal it scores 122,223. These are strong numbers for modern cross-platform APIs. In Passmark tests, the RX 6700 shows a varied profile: DirectX 9 scores 250, DirectX 11 scores 166, DirectX 12 scores 71, and DirectX 10 scores 115. The Passmark G3D score is 18,931, while the GPU compute score is 8,240. The Passmark G2D score is 936. These numbers indicate that the RX 6700 is particularly strong in legacy DirectX 9 workloads, while its DirectX 12 score is comparatively lower, which may reflect driver optimization or architectural priorities.

The Pro Duo has no recorded scores in Vulkan, Metal, or any Passmark tests. Its only benchmark is OpenCL, where it loses heavily to the RX 6700. Therefore, in every measurable category present in the database, the RX 6700 is the winner. There is no test where the Pro Duo demonstrates a comparative advantage. The data simply does not contain any scenario where the older card comes out ahead.

The Verdict

Based strictly on the recorded data, the AMD Radeon RX 6700 is the clear choice for anyone prioritizing compute performance in OpenCL, which is the only shared benchmark. Its score of 97,841 versus 35,860 represents a 63.3% deficit for the Pro Duo. The RX 6700 also has a broader benchmark portfolio, with scores in Vulkan, Metal, and multiple DirectX versions, all of which the Pro Duo lacks. This suggests the RX 6700 is more versatile across modern APIs.

The Pro Duo's 80th percentile ranking is misleading, as it is derived from a single OpenCL score that is far below the RX 6700's. The RX 6700's 75th percentile ranking is based on an average of 30,433 across multiple tests, which is more representative of overall capability. The Pro Duo's nearest rivals, such as the NVIDIA T1000, outperform it by 1.2%, while the RX 6700's nearest rivals, like the RTX 3070 Ti, trail it by 1.6%. This places the RX 6700 in a stronger competitive position relative to its peers.

For a user deciding between these two, the data points unequivocally to the RX 6700. It is faster, more modern, and has more recorded performance data. The Pro Duo retains value only as a historical artifact or in niche scenarios not covered by the database. There is no benchmark result that favors the Pro Duo.

Architecture Differences

The two GPUs come from entirely different architectural generations. The Radeon Pro Duo uses GCN 3.0 architecture, with the chip codenamed "Capsaicin," and belongs to the Radeon Pro GCN generation. The Radeon RX 6700 uses RDNA 2.0 architecture, with the chip codenamed "Navi 22," and belongs to the Navi II (RX 6000) generation. This generational gap explains the massive performance difference.

The process node is a major differentiator: the Pro Duo is built on a 28 nm process at TSMC, while the RX 6700 uses a 7 nm process at the same foundry. The transistor counts reflect this: the Pro Duo has 8,900 million transistors on a 596 mm² die, giving a density of 14.9M per mm². The RX 6700 has 17,200 million transistors on a 335 mm² die, yielding a density of 51.3M per mm². The RX 6700 packs nearly twice as many transistors into a smaller area, which is a direct result of the more advanced node.

The Pro Duo's memory architecture is also fundamentally different. It uses 4 GB of HBM with a 4096-bit bus and a bandwidth of 512.0 GB/s. The RX 6700 uses 10 GB of GDDR6 with a 160-bit bus and a bandwidth of 320.0 GB/s. The Pro Duo has a wider bus and higher bandwidth, but the RX 6700 has more capacity and higher effective memory speed (16 Gbps versus 1000 Mbps effective). The RX 6700 also includes 36 ray tracing cores, a feature entirely absent from the Pro Duo, which has no RT cores listed. This reflects the modern API support: the RX 6700 supports DirectX 12 Ultimate (12_2), while the Pro Duo only supports DirectX 12 (12_0).

Specification Differences

The two cards differ across nearly every specification field. The Pro Duo has 4096 shading units, 256 TMUs, and 64 ROPs, while the RX 6700 has 2304 shading units, 144 TMUs, and 64 ROPs. Despite having fewer shading units, the RX 6700 achieves higher throughput: its FP32 performance is 11.29 TFLOPS versus the Pro Duo's 8.192 TFLOPS. The RX 6700 also has a higher texture rate at 352.8 GTexel/s versus 256.0 GTexel/s, and a higher pixel rate at 156.8 GPixel/s versus 64.00 GPixel/s. The RX 6700's FP16 performance is 22.58 TFLOPS (2:1 ratio), while the Pro Duo's FP16 is 8.192 TFLOPS (1:1 ratio).

The clock speeds are a significant difference. The Pro Duo has no listed base or boost clocks, only a memory clock of 500 MHz (1000 Mbps effective). The RX 6700 has a base clock of 1941 MHz, a boost clock of 2450 MHz, and a game clock of 2174 MHz. The RX 6700's memory clock is 2000 MHz (16 Gbps effective). The Pro Duo's memory bandwidth is higher at 512.0 GB/s versus 320.0 GB/s, but this does not compensate for the compute deficit.

Power and physical specifications also diverge sharply. The Pro Duo has a TDP of 350 W and requires 3x 8-pin power connectors, with a suggested PSU of 750 W. The RX 6700 has a TDP of 175 W, requires a single 8-pin connector, and suggests a 450 W PSU. Both are dual-slot cards, but the Pro Duo is slightly longer at 277 mm (10.9 inches) and taller at 111 mm (4.4 inches), while the RX 6700 is 267 mm (10.5 inches) long, 110 mm (4.3 inches) tall, and 40 mm (1.6 inches) wide. The bus interface differs: the Pro Duo uses PCIe 3.0 x16, while the RX 6700 uses PCIe 4.0 x16. Display outputs also differ: the Pro Duo has 1x HDMI 1.4a and 3x DisplayPort 1.2, while the RX 6700 has 1x HDMI 2.1 and 3x DisplayPort 1.4a. The Pro Duo was released on 2016-04-25, while the RX 6700 was released on 2021-06-08.
