AMD Radeon Pro 560 vs Intel Arc A770M Comparison

The Intel Arc A770M and AMD Radeon Pro 560 occupy different ends of the mobile graphics spectrum, and their benchmark data reflects a clear generational and architectural divide. The Arc A770M, built on Intel’s Xe-HPG architecture, delivers substantially higher raw performance across every shared test, while the Radeon Pro 560, a GCN 4.0 part from 2017, trails by wide margins. The data shows that the Arc A770M is positioned for demanding workloads, whereas the Radeon Pro 560 serves lighter duties with a much smaller footprint.

Where Each One Wins

The Intel Arc A770M wins outright in every benchmark category where both parts have recorded scores. In the head-to-head comparison, the Arc A770M takes both available tests: Geekbench OpenCL and Geekbench Vulkan. The OpenCL result shows the Arc A770M scoring 89,494 against the Radeon Pro 560’s 15,504, a delta of 477.2%. The Vulkan test is similarly lopsided, with the Arc A770M at 74,422 versus 16,232, a 358.5% advantage. There are no benchmark wins for the Radeon Pro 560 in this dataset.

However, the Radeon Pro 560 does have a benchmark that the Arc A770M lacks entirely: Geekbench Metal. The Radeon Pro 560 scores 20,918 in Metal, which suggests it retains some utility in macOS environments, given its Radeon Pro Mac series generation. The Arc A770M has no Metal score listed, so any comparison in that API is impossible from the data. For general-purpose compute and modern graphics APIs, the Arc A770M is the clear choice, but the Radeon Pro 560’s Metal support gives it a unique niche.

Architecture Differences

The two GPUs come from different eras and design philosophies. The Intel Arc A770M uses the DG2-512 chip on a 6 nm TSMC process, packing 21,700 million transistors into a 406 mm² die. The transistor density is 53.4 million per mm². The architecture is Xe-HPG, with the generation labeled Alchemist (Arc 7 Mobile). In contrast, the AMD Radeon Pro 560 uses the Polaris 21 chip on a 14 nm GlobalFoundries process, with 3,000 million transistors on a 123 mm² die. That yields a density of 24.4 million per mm². The architecture is GCN 4.0, from the Radeon Pro Mac (500 Series) generation.

The compute resources differ massively. The Arc A770M has 4,096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. The Radeon Pro 560 has 1,024 shading units, 64 TMUs, and 16 ROPs, with no ray tracing cores. Memory configurations also diverge: the Arc A770M uses 16 GB of GDDR6 on a 256-bit bus, delivering 512.0 GB/s of bandwidth, while the Radeon Pro 560 uses 4 GB of GDDR5 on a 128-bit bus, with 81.28 GB/s. The Arc A770M’s memory clock is 2000 MHz (16 Gbps effective), whereas the Radeon Pro 560’s is 1270 MHz (5.1 Gbps effective).

API support also differs. The Arc A770M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Radeon Pro 560 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The Arc A770M’s ray tracing cores and newer DirectX version give it feature-level advantages that the older GCN part cannot match.

Head-to-Head Benchmarks

The head-to-head data contains only two shared benchmarks, and the Intel Arc A770M wins both by enormous margins. In Geekbench OpenCL, the Arc A770M scores 89,494, which is 477.2% higher than the Radeon Pro 560’s 15,504. This is not a marginal victory; it is a complete rout, indicating that the Arc A770M’s 4096 shading units and 16.79 TFLOPS of FP32 throughput translate directly into compute-heavy application performance. The Radeon Pro 560, with its 1024 shading units and 1.858 TFLOPS, is simply outclassed in this workload.

The Geekbench Vulkan result follows a similar pattern. The Arc A770M scores 74,422, while the Radeon Pro 560 scores 16,232, a 358.5% difference. Vulkan is a low-overhead graphics API, and the Arc A770M’s newer architecture with 32 ray tracing cores and support for DirectX 12 Ultimate likely contributes to its superior performance. The Radeon Pro 560’s GCN 4.0 architecture, despite Vulkan 1.3 support, cannot keep pace with the Arc A770M’s modern design.

Looking at broader benchmark data, the Arc A770M has an average benchmark score of 18,383, placing it in the 62nd percentile of all GPUs. Its nearest rivals include the AMD Radeon RX 460 (average score 18,373, delta 0.1%), the AMD FirePro D500 (18,533, delta -0.8%), the AMD Radeon Pro 5700 (18,189, delta 1.1%), and the NVIDIA GeForce RTX 3060 Mobile (18,159, delta 1.2%). This puts the Arc A770M in a competitive mid-range tier, trading blows with those parts within a 2% margin.

The Radeon Pro 560, meanwhile, has an average benchmark score of 17,551, placing it in the 61st percentile. Its nearest rivals are the AMD Radeon 780M (17,588, delta -0.2%), the AMD Radeon Pro 460 (17,509, delta 0.2%), the NVIDIA Tesla K40c (17,468, delta 0.5%), and the NVIDIA GeForce RTX 4060 (17,639, delta -0.5%). Despite the massive gap between the two GPUs in direct comparison, their percentile ranks are close (62 vs 61), which underscores how the average score metric can obscure extreme differences in specific workloads.

The Arc A770M also shows strong results in legacy DirectX tests, with PassMark scores of 178 in DirectX 9, 69 in DirectX 11, 70 in DirectX 12, and 56 in DirectX 10. Its PassMark G3D score is 11,774, and its GPU Compute score is 4,778. The Radeon Pro 560 has no equivalent PassMark data in this pack, so those numbers cannot be directly compared. The Arc A770M’s 3DMark Steel Nomad DX12 score of 2,278 further demonstrates its capability in modern rasterization workloads, though no equivalent score exists for the Radeon Pro 560.

In summary, the data presents a one-sided contest. The Intel Arc A770M is a high-performance mobile GPU with modern features, while the AMD Radeon Pro 560 is an older, power-efficient part that only finds relevance in Metal-specific environments. Any workload that leverages OpenCL, Vulkan, or DirectX will favor the Arc A770M by a wide margin.
