AMD Radeon Pro Duo vs Intel Arc A530M Comparison

Intel Arc A530M vs AMD Radeon Pro Duo: the data shows a decisive win for the Intel part in compute workloads, but the Radeon Pro Duo retains niche advantages in raw throughput and memory bandwidth that matter for specific professional tasks. The Arc A530M leads by 38.7% in the only directly recorded head-to-head benchmark, Geekbench OpenCL, and holds a higher overall percentile rank. However, the Radeon Pro Duo, despite being end-of-life and built on a much older process, offers nearly double the FP32 throughput and more than double the memory bandwidth, making it a specialist tool for bandwidth-bound or massive parallel workloads that do not rely on modern API features.

The Verdict

For buyers seeking a modern, efficient, and API-complete mobile or embedded solution, the Intel Arc A530M is the clear choice. Its Geekbench OpenCL score of 49,735 versus the Radeon Pro Duo’s 35,860 represents a 38.7% advantage in a widely used compute benchmark. The Arc A530M also ranks in the 85th percentile among all GPUs, compared to the Radeon Pro Duo’s 80th percentile, and its average benchmark score of 46,614 is 30% higher than the Radeon Pro Duo’s 35,860. The Intel card is actively in production, supports DirectX 12 Ultimate, Vulkan 1.4, and has a 65 W TDP, making it suitable for modern systems with limited power budgets.

The AMD Radeon Pro Duo, however, is not obsolete for every purpose. It delivers 8.192 TFLOPS FP32, which is 105% higher than the Arc A530M’s 3.994 TFLOPS, and its 512 GB/s memory bandwidth is 128% higher than the Intel part’s 224 GB/s. The Radeon Pro Duo also has 4,096 shading units and 256 TMUs, versus 1,536 and 96 respectively on the Arc. For workloads that are purely FP32-heavy and fit within its 4 GB HBM memory, the Radeon Pro Duo can outperform the Arc in theoretical throughput, but it lacks hardware ray tracing, supports only DirectX 12 (not Ultimate), and consumes 350 W. The database shows no benchmark wins for the Radeon Pro Duo in the recorded head-to-head tests, so its advantage is purely architectural and theoretical, not measured in application performance.

Choose the Intel Arc A530M for general compute, modern API compatibility, efficiency, and any workload that uses OpenCL or Vulkan. Choose the AMD Radeon Pro Duo only if you have a legacy application that specifically requires massive FP32 throughput and 512 GB/s bandwidth, and you can tolerate a 350 W power draw and end-of-life status.

Architecture Differences

The Intel Arc A530M is built on Intel’s Xe-HPG architecture, specifically the DG2-256 chip, fabricated on a 6 nm process at TSMC. It uses 11,500 million transistors on a 269 mm² die, yielding a transistor density of 42.8 million per mm². This modern design includes 12 ray tracing cores, which the AMD part lacks entirely. The Arc supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it forward-compatible with the latest rendering APIs. Its memory subsystem is 8 GB of GDDR6 on a 128-bit bus, delivering 224 GB/s.

The AMD Radeon Pro Duo is based on the older GCN 3.0 architecture, using the Capsaicin chip on a 28 nm process, also from TSMC. It packs 8,900 million transistors on a much larger 596 mm² die, but with a lower density of 14.9 million per mm². The architecture is a dual-GPU design internally, but the database lists it as a single entry with 4,096 shading units, 256 TMUs, and 64 ROPs. It has no ray tracing cores and supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. Its memory is 4 GB of HBM on a 4096-bit bus, giving 512 GB/s, which is a hallmark of high-bandwidth compute cards from that era. The Radeon Pro Duo is a dual-slot card with three 8-pin power connectors and a 277 mm length, whereas the Arc A530M is an IGP (integrated graphics package) with no dedicated power connectors.

The process node difference is stark: 6 nm versus 28 nm. This explains the Arc’s superior efficiency and feature set, while the Radeon Pro Duo’s larger die and older node allow for higher raw compute but at the cost of power and thermal management.

Head-to-Head Benchmarks

The only recorded head-to-head benchmark is Geekbench OpenCL. The Intel Arc A530M scored 49,735, and the AMD Radeon Pro Duo scored 35,860. This yields a 38.7% delta in favor of the Intel part. The Arc’s average benchmark score across all tests is 46,614, while the Radeon Pro Duo’s average is 35,860, meaning the Arc is 30% higher on average. In the percentile ranking, the Arc sits at 85, the Radeon Pro Duo at 80, a five-point gap.

Examining nearest rivals for context: the Arc’s closest competitor is the AMD Radeon RX 5600M with an average score of 46,601, a 0% delta, meaning they are statistically tied. The Arc also sits 0.2% above the RX 6550M (46,702) and 1.2% above the NVIDIA RTX A2000 (46,043). For the Radeon Pro Duo, its nearest rival is the NVIDIA Quadro GV100 with an average score of 35,520, a 1% delta in favor of the Radeon. It is 1.2% above the RTX 5070 Ti Mobile (35,435) and 1.2% below the NVIDIA T1000 (36,289). This shows that while the Arc is competitive with modern mid-range GPUs, the Radeon Pro Duo is only comparable to older or lower-tier professional parts.

The Geekbench OpenCL result is the strongest evidence of real-world compute performance. Despite the Radeon Pro Duo’s theoretical FP32 advantage, the Arc’s modern architecture, driver optimizations, and API support translate to better measured performance in OpenCL. There is no recorded benchmark where the Radeon Pro Duo wins.

Where Each One Wins

The Intel Arc A530M wins in all recorded benchmarks, including Geekbench OpenCL and the average benchmark score. It also wins on efficiency, with a 65 W TDP versus 350 W, making it viable for thin laptops or small form factor systems. It supports ray tracing, DirectX 12 Ultimate, and Vulkan 1.4, which are essential for modern game development, AI inference on newer frameworks, and any workload requiring the latest graphics features. Its 8 GB memory capacity is twice that of the Radeon Pro Duo, which is critical for larger datasets in compute tasks that exceed 4 GB. The Arc is also built on a 6 nm process, meaning it is smaller, cooler, and more reliable for long-term deployment.

The AMD Radeon Pro Duo wins on theoretical raw compute and memory bandwidth. Its 8.192 TFLOPS FP32 is double the Arc’s 3.994 TFLOPS, and its 512 GB/s bandwidth is more than double the Arc’s 224 GB/s. For workloads that are purely FP32-heavy and do not rely on ray tracing or modern API features, such as certain scientific simulations, legacy CAD, or older rendering pipelines, the Radeon Pro Duo can process large arrays faster in theory. Its 4,096 shading units and 256 TMUs also suggest better texture-heavy throughput, with a texture rate of 256 GTexel/s versus 124.8 GTexel/s. However, these advantages are not reflected in the recorded benchmark data, which shows the Arc winning the only direct comparison. The Radeon Pro Duo’s 4 GB memory is a severe constraint for modern workloads, and its 350 W power draw and end-of-life status make it a poor choice for new systems.

In summary, the Arc A530M wins for anyone needing a current, efficient, and benchmark-proven GPU. The Radeon Pro Duo wins only for a narrow set of legacy, bandwidth-saturated compute tasks where its theoretical specs are the sole consideration and modern API support is irrelevant. The database’s measurements strongly favor the Intel part, and the Radeon Pro Duo’s architectural advantages do not translate into recorded wins.
