AMD Radeon Pro 560 vs Intel Arc A750 Comparison

Intel Arc A750 vs AMD Radeon Pro 560 is a study in generational and architectural extremes. The Arc A750, a desktop add-in board from Intel's Alchemist generation, overwhelms the AMD Radeon Pro 560, a low-power mobile-class part from 2017, in every measurable benchmark category. The data shows a decisive victory for Intel, with the Arc A750 landing in the 66th percentile of all GPUs versus the Radeon Pro 560's 61st percentile. The verdict is straightforward: the Arc A750 is for anyone needing modern DirectX 12 Ultimate or Vulkan performance, while the Radeon Pro 560 is a legacy part with no practical use case in current workloads.

The Verdict

The benchmark results are unambiguous. The Intel Arc A750 wins both head-to-head tests by staggering margins: 535.7% in Geekbench OpenCL and 427.5% in Geekbench Vulkan. Average benchmark scores reinforce this gap, with the Arc A750 scoring 20,582 against the Radeon Pro 560's 17,551. The Arc A750 sits within 0.5% of rivals like the NVIDIA Quadro M4000M and AMD Radeon R9 M390X, while the Radeon Pro 560 trades blows with the AMD Radeon 780M and NVIDIA GeForce RTX 4060, all within a 0.5% delta. For any modern gaming, rendering, or compute task, the Arc A750 is the only viable choice. The Radeon Pro 560, with its 4 GB of GDDR5 memory and 75 W TDP, is strictly a legacy part for older Mac systems. No current application benefits from its 1.858 TFLOPS of FP32 performance when the Arc A750 delivers 17.20 TFLOPS.

Architecture Differences

The architectural chasm between these two GPUs is extreme. Intel's Arc A750 uses the DG2-512 chip built on the Xe-HPG architecture, fabricated on a 6 nm TSMC process with 21,700 million transistors on a 406 mm² die. This yields a transistor density of 53.4 million per square millimeter. The AMD Radeon Pro 560 uses the Polaris 21 chip on the GCN 4.0 architecture, built on a 14 nm GlobalFoundries process with just 3,000 million transistors on a 123 mm² die, a density of 24.4 million per square millimeter. The Arc A750 has 3,584 shading units, 224 texture mapping units, 112 ROPs, and 28 ray tracing cores. The Radeon Pro 560 has 1,024 shading units, 64 TMUs, and 16 ROPs, with no ray tracing hardware at all. Intel's part supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while AMD's part supports DirectX 12 (12_0) and Vulkan 1.3. The Arc A750 also has a 256-bit memory bus with 8 GB of GDDR6, delivering 512.0 GB/s of bandwidth, versus the Radeon Pro 560's 128-bit bus with 4 GB of GDDR5 at 81.28 GB/s. The A750's memory clock runs at 2000 MHz (16 Gbps effective), while the Pro 560's runs at 1270 MHz (5.1 Gbps effective). These differences are not incremental; they are generational leaps in every subsystem.
