AMD Radeon Pro 575X vs Intel Arc A530M Comparison

The Verdict

The benchmark database presents a clear hierarchy: the Intel Arc A530M outperforms the AMD Radeon Pro 575X in every recorded head-to-head test. The Arc A530M wins both available comparisons, securing a 43% advantage in OpenCL and a 14.7% edge in Vulkan. Its average benchmark score of 46614 places it at the 85th percentile of all GPUs, while the Radeon Pro 575X sits at the 82nd percentile with an average of 39116.

The Intel part belongs to a newer generation, the Alchemist line for Arc 5 Mobile, and is built on a 6 nm process. The AMD part is from the Radeon Pro Mac 500X series, using the older GCN 4.0 architecture on a 14 nm node. The data suggests the Arc A530M is the better choice for compute-heavy workloads that leverage OpenCL or Vulkan, and its higher percentile ranking reinforces that conclusion.

For users constrained to the older AMD part, perhaps due to platform compatibility or existing system integration, the Radeon Pro 575X remains a functional GPU, but it trails the Intel offering in raw performance metrics. The Verdict is straightforward: when both are available, the Arc A530M is the superior performer in the tests recorded.

Architecture Differences

The two GPUs represent distinct design philosophies separated by several years of development. The Intel Arc A530M uses the DG2-256 chip based on the Xe-HPG architecture, fabricated by TSMC on a 6 nm process. This is a dense implementation, packing 11,500 million transistors into a 269 mm² die, yielding a transistor density of 42.8 million per square millimeter. The AMD Radeon Pro 575X uses the Ellesmere chip with GCN 4.0 architecture, produced by GlobalFoundries on a 14 nm node. It houses 5,700 million transistors on a 232 mm² die, resulting in a density of 24.6 million per square millimeter.

The Intel part features dedicated ray tracing cores (12 of them) and supports DirectX 12 Ultimate (12_2), while the AMD part has no ray tracing hardware and is limited to DirectX 12 (12_0). The Arc A530M also supports Vulkan 1.4, whereas the Radeon Pro 575X supports Vulkan 1.3. Both GPUs are integrated into portable devices, but their internal designs diverge sharply.

The memory subsystems differ fundamentally. The Arc A530M uses 8 GB of GDDR6 on a 128-bit bus, delivering 224.0 GB/s of bandwidth. The Radeon Pro 575X has 4 GB of GDDR5 on a 256-bit bus, providing 217.0 GB/s. Despite the wider bus on the AMD part, the Intel GPU achieves slightly higher bandwidth due to faster memory clocks (14 Gbps effective versus 6.8 Gbps effective).

The shader configurations also tell a story. The Arc A530M has 1536 shading units, 96 texture mapping units, and 48 ROPs. The Radeon Pro 575X has 2048 shading units, 128 TMUs, and 32 ROPs. The AMD part has more raw shading hardware, yet the Intel part wins in practice, suggesting architectural efficiency gains in Xe-HPG.

The power envelopes are dramatically different. The Arc A530M is rated at 65 W TDP, while the Radeon Pro 575X draws 150 W. This is a notable efficiency gap, with the Intel part delivering higher performance while consuming less than half the power. The AMD GPU has no power connectors, which is typical for mobile integrated parts, but its higher TDP still imposes thermal constraints.

Head-to-Head Benchmarks

The recorded data shows two direct comparisons, and the Intel Arc A530M wins both. In Geekbench OpenCL, the Arc A530M scores 49735 against the Radeon Pro 575X's 34773. That is a 43% delta in favor of Intel. This is a substantial margin, indicating that the Arc A530M handles compute workloads with significantly greater efficiency, likely due to its newer architecture and higher memory bandwidth.

In Geekbench Vulkan, the gap narrows but remains decisive. The Arc A530M scores 43492, while the Radeon Pro 575X manages 37919. The delta is 14.7%. This smaller margin suggests that the Vulkan API levels the playing field somewhat, possibly because the AMD part's higher shading unit count allows it to keep pace better in graphics-oriented tasks. Still, the Intel GPU comes out ahead in both API environments.

The absence of a Metal benchmark for the Intel part is notable. The Radeon Pro 575X has a Geekbench Metal score of 44655, which is its best individual result. Since the Arc A530M lacks a Metal entry in the database, direct comparison in that API is impossible. However, the Intel GPU's OpenCL and Vulkan scores both exceed the AMD part's Metal score, which suggests the Intel GPU would likely perform competitively if Metal were tested.

For context, the Arc A530M's nearest rivals in the database include the AMD Radeon RX 5600M (average 46601, delta 0%), the AMD Radeon RX 6550M (46702, delta -0.2%), the NVIDIA RTX A2000 (46043, delta 1.2%), and the NVIDIA RTX 5880 Ada Generation (45972, delta 1.4%). The Radeon Pro 575X sits near the AMD Radeon Pro 580X (38706, delta 1.1%), the NVIDIA GeForce MX570 A (38691, delta 1.1%), the AMD Radeon Pro 575 (39555, delta -1.1%), and the NVIDIA RTX A500 Mobile (39568, delta -1.1%). This places the Arc A530M in a higher performance tier overall.

Where Each One Wins

The Intel Arc A530M wins in every recorded benchmark category, so the analysis must focus on the degree of its dominance and the contexts where the AMD part might still have a niche. The Arc A530M's 43% lead in OpenCL makes it the clear choice for compute-heavy applications using that API, such as scientific simulations, data processing, or machine learning inference. Its 14.7% lead in Vulkan positions it well for modern cross-platform gaming and graphics workloads. The Intel part also has a massive advantage in efficiency, delivering higher performance at 65 W versus 150 W, which matters in thermally constrained mobile chassis.

The AMD Radeon Pro 575X does have some theoretical advantages. Its FP32 throughput is higher, and it has more shading units and TMUs, which could favor certain legacy workloads that are not well represented in the current benchmark suite. Its 256-bit memory bus might also help in specific bandwidth-sensitive patterns that do not appear in the recorded tests. However, the actual measured data shows the Intel part ahead in both available comparisons, and the AMD GPU's lower percentile ranking (82 versus 85) suggests it falls behind more broadly across the database.

For users locked into AMD's Radeon Pro Mac ecosystem, the 575X remains a functional option, and its Metal score of 44655 is respectable. But the Intel Arc A530M's OpenCL and Vulkan scores both exceed that Metal result. The AMD part may also have an edge in price-to-performance if it is available at a significant discount, but the database does not provide pricing data, so that remains speculative.

The clearest use-case split is between new deployments and legacy integrations. The Arc A530M is the better choice for any new system where its 6 nm process and 8 GB of GDDR6 provide future-proofing. The Radeon Pro 575X is only relevant for maintaining compatibility with existing hardware or for workloads that specifically require GCN 4.0 features that are absent from newer architectures. The data does not show a single test where the AMD part wins, so the recommendation is straightforward: the Intel Arc A530M is the superior GPU in this comparison.
