Intel Arc A530M vs Intel Arc A770 Comparison

Head-to-Head Benchmarks

The benchmark data reveals a decisive pattern in favor of the Intel Arc A770 across every recorded test. In the Geekbench OpenCL compute workload, the A770 scores 109,175 points, while the Arc A530M manages 49,735 points. That translates to a 119.5% advantage for the desktop card, meaning the A770 more than doubles the mobile part's raw compute throughput in this API. The gap is not marginal; it is a generational chasm in execution resources.

The Vulkan test tells a similar story, though with a slightly narrower margin. The Arc A770 posts 94,284 points, against 43,492 points for the Arc A530M. The delta here is 116.8%, still a commanding lead. Vulkan tends to scale with shader count and memory bandwidth, both of which heavily favor the A770. The recorded data shows the A770 wins both head-to-head matchups, giving it a clean 2-0 record over the A530M.

Context within the broader database strengthens the interpretation. The Arc A770 sits at the 90th percentile among all GPUs, with an average benchmark score of 68,809. Its nearest rivals include the NVIDIA CMP 90HX at 69,000 (0.3% behind), the AMD Radeon Instinct MI25 at 68,562 (0.4% ahead), the AMD Radeon Pro WX 8200 at 69,870 (1.5% behind), and the NVIDIA Quadro P6000 at 69,986 (1.7% behind). These are tight margins, indicating the A770 competes in a dense cluster of workstation-class cards. The A530M, by contrast, holds the 85th percentile, with an average score of 46,614. Its nearest rivals are the AMD Radeon RX 5600M at 46,601 (a 0% delta), the AMD Radeon RX 6550M at 46,702 (0.2% behind), the NVIDIA RTX A2000 at 46,043 (1.2% ahead), and the NVIDIA RTX 5880 Ada Generation at 45,972 (1.4% ahead). The A530M's position is essentially level with its immediate competitors, whereas the A770 sits at the top edge of its own peer group.

The average score differential between the two cards is stark: 68,809 versus 46,614. That is a 47.6% gap in aggregate performance, even before isolating individual workloads. The head-to-head deltas are even larger, suggesting the A770's advantage is not merely average but consistent across diverse rendering and compute paths.

Architecture Differences

Both cards belong to Intel's Xe-HPG architecture and the Alchemist generation, but they are built on different silicon. The Arc A770 uses the DG2-512 chip, while the Arc A530M uses the DG2-256 die. The naming reflects the physical difference: 512 execution units versus 256, though the actual shader counts tell a more precise story. The A770 packs 4,096 shading units, 256 texture mapping units, 128 ROPs, and 32 ray tracing cores. The A530M halves most of those numbers: 1,536 shading units, 96 TMUs, 48 ROPs, and 12 RT cores. This is not a minor trim; it is a fundamental reduction in parallel processing capacity.

The process node is identical, 6 nm at TSMC, but the transistor budgets diverge sharply. The A770 integrates 21,700 million transistors on a 406 mm² die, yielding a transistor density of 53.4 million per square millimeter. The A530M uses 11,500 million transistors on a 269 mm² die, with a density of 42.8 million per square millimeter. The A770's larger die and higher density give it more headroom for compute blocks, while the A530M's smaller footprint suits its mobile role.

Clock behavior also separates the two. The A770 runs at a 2100 MHz base and 2400 MHz boost, whereas the A530M operates at 900 MHz base and 1300 MHz boost. The boost delta is substantial: 1100 MHz higher on the desktop part. This compounds with the shader advantage, producing a multiplicative effect on throughput. The memory subsystem follows the same pattern. The A770 uses 16 GB of GDDR6 on a 256-bit bus, delivering 512.0 GB/s of bandwidth. The A530M halves the bus to 128 bits and the capacity to 8 GB, with 224.0 GB/s. Memory clock rates differ as well: 2000 MHz (16 Gbps effective) for the A770 versus 1750 MHz (14 Gbps effective) for the A530M.

Feature support is identical at the API level. Both cards expose DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. That means the architectural differences do not translate into missing feature sets; the A530M can run the same workloads, just with fewer resources. The A770's pixel rate is 307.2 GPixel/s versus 62.40 GPixel/s on the A530M, and texture rate is 614.4 GTexel/s versus 124.8 GTexel/s. FP32 compute is 19.66 TFLOPS versus 3.994 TFLOPS, and FP16 is 39.32 TFLOPS versus 7.987 TFLOPS, both with a 2:1 ratio.

The Verdict

The data points to a clear conclusion: the Intel Arc A770 is the superior performer in every recorded benchmark. The 119.5% lead in OpenCL and 116.8% lead in Vulkan are not close calls. For any workload that leverages compute shaders, ray tracing, or high-bandwidth memory, the A770 is the definitive choice. The 16 GB frame buffer and 512.0 GB/s bandwidth make it suitable for large datasets and high-resolution textures, while the 4,096 shading units provide ample parallelism for modern rendering pipelines.

The Arc A530M, however, serves a different purpose. Its 65 W TDP and IGP slot width indicate a mobile-first design, prioritizing power efficiency over peak performance. It still holds the 85th percentile among all GPUs, which is respectable for a laptop part. Its 8 GB memory and 224.0 GB/s bandwidth are adequate for mainstream gaming and content creation on the go. The A530M's nearest rival deltas are tiny, within 1.4%, meaning it is well positioned in its own segment.

Who should pick which? The A770 is for desktop users who need maximum compute density, whether for rendering, simulation, or high-end gaming. The A530M is for portable systems where the 225 W TDP of the A770 is impractical. The A770 is end-of-life, while the A530M remains active, but that status does not change the performance hierarchy. The recorded data shows no scenario where the A530M outpaces the A770.
