AMD Radeon Pro 575 vs Intel Arc A550M Comparison

Head-to-Head Benchmarks

The recorded data shows a clear and consistent performance gap between the Intel Arc A550M and the AMD Radeon Pro 575 across the two shared benchmark tests. In Geekbench OpenCL, the Intel Arc A550M scores 49,894 points against the AMD Radeon Pro 575's 34,596 points. That translates to a 44.2% advantage for the Intel part, a substantial margin that places the two GPUs in different performance tiers. The AMD Radeon Pro 575's OpenCL result is closer to its nearest rival, the AMD Radeon Pro 580, which averages 40,318 points, while the Intel Arc A550M sits just 0.4% behind the NVIDIA GeForce RTX 5070 Ti's average of 49,957 points.

The Vulkan results follow the same pattern, though with a slightly narrower gap. The Intel Arc A550M records 49,580 points, while the AMD Radeon Pro 575 manages 37,878 points. The delta here is 30.9% in favor of Intel. Notably, the Intel part's Vulkan score is nearly identical to its OpenCL score, differing by only 314 points, which suggests consistent compute behavior across these two APIs. The AMD part, by contrast, shows a larger spread between its API scores: its Vulkan result is 9.3% higher than its OpenCL result, and its Metal score of 46,192 points is the highest among its three recorded benchmarks, indicating a platform-specific strength.

Looking at the aggregate averages, the Intel Arc A550M holds an average benchmark score of 49,737 across its two tests, while the AMD Radeon Pro 575 averages 39,555 across three tests. The Intel part's average places it in the 86th percentile of all GPUs in the database, while the AMD part sits in the 82nd percentile. This percentile gap, though modest, underlines that the Intel Arc A550M competes with much higher-end hardware: its average is within 0.4% of the NVIDIA GeForce RTX 5070 Ti and within 0.5% of the AMD Radeon RX Vega 64. The AMD Radeon Pro 575, on the other hand, is effectively tied with the NVIDIA RTX A500 Mobile (0% delta) and sits 1.1% ahead of the AMD Radeon Pro 575X.

Architecture Differences

The underlying architectures diverge sharply between these two products. The Intel Arc A550M is built on the Xe-HPG architecture, specifically the DG2-512 chip, and belongs to the Alchemist generation (Arc 5 Mobile). It is fabricated on a 6 nm process at TSMC, packing 21,700 million transistors into a 406 mm² die. The transistor density works out to 53.4 million transistors per square millimeter. The AMD Radeon Pro 575, in contrast, uses the GCN 4.0 architecture with the Ellesmere chip, part of the Radeon Pro Mac (500 Series) generation. It is built on a 14 nm process at GlobalFoundries, with 5,700 million transistors on a 232 mm² die, yielding a density of 24.6 million transistors per square millimeter. The Intel chip carries nearly four times the transistor count on a die that is 75% larger, a direct consequence of the newer, denser process node.

Core configurations show both similarities and differences. Both GPUs have 2,048 shading units and 128 texture mapping units. However, the Intel Arc A550M has 64 raster operation pipelines (ROPs), double the 32 ROPs on the AMD Radeon Pro 575. The Intel part also includes 16 dedicated ray tracing cores, while the AMD part has none. This is a fundamental feature split: the Intel Arc A550M supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, whereas the AMD Radeon Pro 575 is limited to DirectX 12 (12_0) and Vulkan 1.3. Both support OpenGL 4.6.

Memory subsystems differ in capacity, type, and bus width. The Intel Arc A550M comes with 8 GB of GDDR6 memory on a 128-bit bus, delivering 224.0 GB/s of bandwidth. The AMD Radeon Pro 575 has 4 GB of GDDR5 memory on a 256-bit bus, providing 217.0 GB/s. Despite the Intel part's narrower bus, its higher memory clock (1750 MHz, 14 Gbps effective versus 1695 MHz, 6.8 Gbps effective) nearly closes the bandwidth gap, leaving only a 3.2% difference in favor of Intel. The AMD part's wider bus is a legacy design choice, while Intel's approach relies on faster memory to compensate.

Clock speeds also tell a story. The Intel Arc A550M has a base clock of 900 MHz and a boost clock of 2050 MHz. The AMD Radeon Pro 575 has no base or boost clock listed in the database, only a memory clock. This absence of clock data makes direct frequency comparisons impossible, but the performance results speak to the Intel part's higher effective throughput.

Where Each One Wins

The Intel Arc A550M wins both head-to-head benchmark comparisons, but the nature of those wins differs. In OpenCL, the Intel part is 44.2% ahead, a dominant margin that suggests a strong general-purpose compute advantage. In Vulkan, the lead shrinks to 30.9%, still decisive but less overwhelming. The AMD Radeon Pro 575 does have one area of relative strength: its Metal benchmark score of 46,192 points is substantially higher than its OpenCL and Vulkan scores, indicating that the GPU is better optimized for Apple's Metal API, consistent with its Radeon Pro Mac positioning. However, the Intel Arc A550M has no Metal benchmark recorded in the database, so a direct comparison on that API is not possible.

For workloads that rely on OpenCL or Vulkan, the Intel Arc A550M is the clear choice based on the data. Its average benchmark score of 49,737 places it in the 86th percentile, meaning it outperforms 86% of all GPUs in the database. The AMD Radeon Pro 575, at the 82nd percentile, is also a capable part, but it trails in both shared tests. The AMD part's nearest rival, the NVIDIA RTX A500 Mobile, has an identical average score of 39,568 (0% delta), which puts the Radeon Pro 575 in a competitive bracket with other mobile professional GPUs of its era.

Where the AMD Radeon Pro 575 might still find a niche is in legacy or Metal-centric environments. Its Vulkan score of 37,878 is 9.5% higher than its OpenCL score, and its Metal score is 33.5% higher than its OpenCL score. This suggests that the GPU's performance is highly API-dependent, and for users constrained to Metal, the AMD part may punch above its OpenCL numbers. The Intel Arc A550M, by contrast, shows near-parity between OpenCL and Vulkan (a 0.6% difference), indicating more consistent cross-API behavior.

The Verdict

The data is unambiguous: the Intel Arc A550M is the faster GPU in every shared benchmark. It leads by 44.2% in OpenCL and 30.9% in Vulkan, holds a 25.7% higher average benchmark score, and sits four percentile points higher in the overall GPU ranking. The Intel part also brings modern features that the AMD part lacks, including ray tracing cores, DirectX 12 Ultimate support, and a newer process node with vastly higher transistor density.

For users prioritizing compute performance in OpenCL or Vulkan workloads, the Intel Arc A550M is the only rational choice between these two. Its average score of 49,737 rivals desktop-class GPUs like the AMD Radeon RX 6900 XT (50,951, 2.4% higher) and the AMD Radeon RX 6800 XT (48,477, 2.6% lower), making it a remarkably strong mobile part. The AMD Radeon Pro 575, with an average of 39,555, is closer to the NVIDIA RTX A500 Mobile and the AMD Radeon Pro WX 7100, a different performance class entirely.

The AMD part does have one claim to relevance: its Metal performance. At 46,192 points, the Metal score is closer to the Intel Arc A550M's averages than any other AMD benchmark result, though without a direct Intel Metal comparison, this remains an incomplete picture. For any user working outside of Metal-specific Apple ecosystems, the Intel Arc A550M wins on every metric recorded.
