AMD Radeon 880M vs AMD Radeon Pro Duo Comparison

The AMD Radeon Pro Duo and the AMD Radeon 880M represent two distant points in GPU design: a 2016 high-power desktop compute card and a 2024 integrated mobile processor. Despite the eight-year gap and radically different form factors, their average benchmark scores sit close—35,860 for the Pro Duo versus 35,646 for the 880M, a 0.6% gap in the Pro Duo’s favor. But that near-parity masks stark differences in raw throughput, feature support, and power envelope. The Pro Duo wins the only shared OpenCL test by 14.6%, while the 880M counters with Vulkan 1.4, 12 ray-tracing cores, and a 15 W TDP. The right choice depends entirely on whether the workload is legacy compute or modern mobile graphics.

The Verdict

The AMD Radeon Pro Duo is the pick for compute-heavy tasks that rely on OpenCL and FP32 throughput. It delivers 8.192 TFLOPS FP32, 64.00 GPixel/s pixel rate, and 256.0 GTexel/s texture rate—all substantially ahead of the 880M’s 4.454 TFLOPS, 46.40 GPixel/s, and 139.2 GTexel/s. In the head-to-head OpenCL benchmark, the Pro Duo scores 35,860 against the 880M’s 31,285, a 14.6% lead. Its 512.0 GB/s memory bandwidth on a 4096-bit bus dwarfs the 880M’s system-shared memory, which has no fixed bandwidth figure. For anyone running legacy OpenCL workloads on a desktop, the Pro Duo is the data-backed winner.

The AMD Radeon 880M is the choice when modern API support, mobility, and efficiency matter. It is an active, 4 nm integrated GPU with a boost clock of 2900 MHz, 12 ray-tracing cores, and Vulkan 1.4 support—features the Pro Duo lacks entirely. Its FP16 throughput of 8.909 TFLOPS exceeds the Pro Duo’s 8.192 TFLOPS, and its Vulkan benchmark score of 40,006 is higher than the Pro Duo’s OpenCL score of 35,860. At 15 W TDP with no external power connectors, it operates in a completely different power class than the Pro Duo’s 350 W, dual-slot, 3x 8-pin design. For portable devices or systems where efficiency and modern graphics features are paramount, the 880M is the only viable option.

Architecture Differences

The two GPUs are built on fundamentally different architectures and process nodes. The Pro Duo uses GCN 3.0 on a 28 nm TSMC process, with 8,900 million transistors on a 596 mm² die, yielding a transistor density of 14.9M / mm². The 880M uses RDNA 3.5 on a 4 nm TSMC process, packing 34,000 million transistors into a 233 mm² die—a density of 145.9M / mm², nearly ten times higher. The 880M’s chip is codenamed Strix Point, while the Pro Duo’s chip is called Capsaicin; the Pro Duo belongs to the Radeon Pro GCN generation, the 880M to the Navi III IGP (Strix Point Mobile) generation.

Compute resources differ sharply. The Pro Duo has 4096 shading units, 256 TMUs, and 64 ROPs, while the 880M has 768 shading units, 48 TMUs, and 16 ROPs. The 880M adds 12 ray-tracing cores; the Pro Duo has none. The Pro Duo’s memory is 4 GB of HBM on a 4096-bit bus with 512.0 GB/s bandwidth, while the 880M uses system-shared memory with a system-dependent bandwidth. The Pro Duo’s memory clock is 500 MHz (1000 Mbps effective); the 880M’s base clock is 400 MHz and boost clock is 2900 MHz, but its memory clock is not specified.

API support diverges as well. The Pro Duo supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The 880M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The 880M also has a higher FP16-to-FP32 ratio (2:1) versus the Pro Duo’s 1:1, meaning the 880M’s FP16 throughput is 8.909 TFLOPS, slightly above the Pro Duo’s 8.192 TFLOPS, even though its FP32 is less than half.

Where Each One Wins

Based on benchmark data and specifications, the Pro Duo wins in raw compute throughput. Its OpenCL score of 35,860 is 14.6% higher than the 880M’s 31,285. It also leads in FP32 (8.192 vs. 4.454 TFLOPS), pixel rate (64.00 vs. 46.40 GPixel/s), and texture rate (256.0 vs. 139.2 GTexel/s). Its memory bandwidth of 512.0 GB/s is fixed and high, while the 880M’s is system-dependent. The Pro Duo’s shading unit count (4096 vs. 768) and TMU count (256 vs. 48) give it a massive parallel throughput advantage.

The 880M wins in modern features and efficiency. It has a Vulkan score of 40,006, which is higher than the Pro Duo’s OpenCL score of 35,860, and it supports Vulkan 1.4 and DirectX 12 Ultimate. It includes 12 ray-tracing cores, a feature absent from the Pro Duo. Its FP16 throughput of 8.909 TFLOPS exceeds the Pro Duo’s 8.192 TFLOPS. The 880M’s 15 W TDP is a fraction of the Pro Duo’s 350 W, and it requires no external power connectors. The 880M is also an active product with a 2024 release date, while the Pro Duo is end-of-life with a 2016 release.

Head-to-Head Benchmarks

The only direct benchmark comparison in the data is Geekbench OpenCL. The AMD Radeon Pro Duo scores 35,860, and the AMD Radeon 880M scores 31,285. This gives the Pro Duo a 14.6% lead. The Pro Duo’s average benchmark score is 35,860, while the 880M’s average is 35,646, meaning the Pro Duo leads by 0.6% in the overall average. The Pro Duo’s percentile ranking is 80th versus the 880M’s 79th.

The 880M’s Vulkan score of 40,006 is notable because it exceeds the Pro Duo’s OpenCL score, but no Vulkan result exists for the Pro Duo to compare directly. The 880M’s average score is pulled down by its lower OpenCL result; its Vulkan result is higher than its own OpenCL result and higher than the Pro Duo’s OpenCL score. However, the head-to-head table only includes the OpenCL test, where the Pro Duo wins decisively.
