AMD Radeon Pro 575X vs Intel Arc A550M Comparison

Head-to-Head Benchmarks

The recorded benchmark data shows a decisive performance advantage for the Intel Arc A550M across all shared test workloads. In the Geekbench OpenCL test, the Intel Arc A550M scores 49,894 points against the AMD Radeon Pro 575X’s 34,773 points. That is a 43.5% lead for the Intel part, a substantial margin that places the two GPUs in different performance tiers despite both having 2,048 shading units. The OpenCL result is the largest single gap in the head-to-head comparison.

The Vulkan test narrows the gap but still leaves the AMD part trailing by a significant margin. The Intel Arc A550M records 49,580 points, while the AMD Radeon Pro 575X manages 37,919 points. The delta here is 30.8% in favor of Intel. While Vulkan is generally a more efficient API for AMD’s architecture than OpenCL, the 30.8% deficit is still too large for the Radeon Pro 575X to overcome. The data shows that the Intel part wins both head-to-head benchmarks, giving it a 2-0 record in direct comparisons.

Context from the database’s nearest rival lists reinforces the divide. The Intel Arc A550M’s average benchmark score is 49,737. That places it within 0.4% of the NVIDIA GeForce RTX 5070 Ti (49,957) and 0.5% of the AMD Radeon RX Vega 64 (50,001). It also sits 2.4% below the AMD Radeon RX 6900 XT (50,951) but 2.6% above the AMD Radeon RX 6800 XT (48,477). In contrast, the AMD Radeon Pro 575X’s average score is 39,116. That is only 1.1% above the AMD Radeon Pro 580X (38,706) and the NVIDIA GeForce MX570 A (38,691), and 1.1% below the AMD Radeon Pro 575 (39,555) and the NVIDIA RTX A500 Mobile (39,568). The Intel part’s average score is roughly 27% higher than the AMD part’s average, a gap that is consistent with the individual test deltas.

The percentile rankings show where each GPU sits relative to the entire database. The Intel Arc A550M is in the 86th percentile of all GPUs, while the AMD Radeon Pro 575X is in the 82nd percentile. That four-point spread in percentiles understates the raw score difference, but it reflects how the database’s distribution compresses near the top.

Architecture Differences

The two GPUs come from fundamentally different architectural generations. 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). The AMD Radeon Pro 575X uses the GCN 4.0 architecture with the Ellesmere chip, part of the Radeon Pro Mac (500X Series) generation. This generational gap explains much of the performance difference.

The manufacturing process separates them sharply. Intel uses a 6 nm process from TSMC, while AMD uses a 14 nm process from GlobalFoundries. The transistor counts reflect this: the Intel chip packs 21,700 million transistors on a 406 mm² die, yielding a transistor density of 53.4 million transistors per square millimeter. The AMD chip has 5,700 million transistors on a 232 mm² die, for a density of 24.6 million per square millimeter. The Intel chip has nearly four times the transistor count on a die that is only about 75% larger. This density advantage allows the Intel architecture to pack far more compute resources into a similar power envelope.

Memory configurations differ in capacity and type. The Intel Arc A550M has 8 GB of GDDR6 memory on a 128-bit bus, with a memory clock of 1750 MHz (14 Gbps effective) and bandwidth of 224.0 GB/s. The AMD Radeon Pro 575X has 4 GB of GDDR5 memory on a 256-bit bus, with a memory clock of 1695 MHz (6.8 Gbps effective) and bandwidth of 217.0 GB/s. The Intel part offers double the capacity and slightly higher bandwidth despite a narrower bus, thanks to faster memory technology.

Compute resources show a mixed picture. Both GPUs have 2,048 shading units and 128 texture mapping units. However, the Intel part has 64 raster operation units (ROPs) versus 32 for AMD, and it includes 16 ray tracing cores while the AMD part has none. The pixel rate for the Intel GPU is 131.2 GPixel/s versus 35.07 GPixel/s for AMD, a 3.7x advantage. The texture rate is 262.4 GTexel/s versus 140.3 GTexel/s, a 1.9x advantage. The FP32 throughput is 8.397 TFLOPS for Intel versus 4.489 TFLOPS for AMD. For FP16, the Intel part reaches 16.79 TFLOPS (2:1 ratio), while the AMD part is capped at 4.489 TFLOPS (1:1 ratio). The AMD part’s FP16 rate is identical to its FP32 rate, indicating no dedicated fast path for half-precision.

Power and interface details also diverge. The Intel Arc A550M has a TDP of 60 W, while the AMD Radeon Pro 575X has a TDP of 150 W. This is a striking reversal: the faster GPU draws significantly less power. The Intel part uses a PCIe 4.0 x16 interface, while the AMD part uses PCIe 3.0 x16. Both are integrated into portable devices with no slot width, and the AMD part explicitly lists no power connectors. API support favors Intel: DirectX 12 Ultimate (12_2) versus DirectX 12 (12_0), Vulkan 1.4 versus 1.3, and both support OpenGL 4.6.

The Verdict

The benchmark data is unambiguous: the Intel Arc A550M is the superior GPU for raw performance. It wins both head-to-head tests by margins of 43.5% and 30.8%, and its average score of 49,737 is roughly 27% higher than the AMD Radeon Pro 575X’s 39,116. The Intel part also does this while drawing 60 W versus 150 W, making it the more efficient choice on paper.

The AMD Radeon Pro 575X does not have a single recorded benchmark win over the Intel part. Its only advantages are architectural in nature: it uses a wider 256-bit memory bus and has a lower transistor density, but these do not translate into performance gains in the measured tests. The AMD part’s nearest rivals are all in the 38,000 to 39,500 score range, while the Intel part’s nearest rivals are in the 48,000 to 51,000 range. That places them in entirely different competitive brackets.

Who should pick which? From the data, anyone seeking higher compute throughput in OpenCL and Vulkan workloads should choose the Intel Arc A550M. The 43.5% OpenCL lead and 30.8% Vulkan lead are too large to ignore. The Intel part also offers double the memory capacity (8 GB versus 4 GB) and ray tracing support, which the AMD part lacks entirely. The AMD Radeon Pro 575X might be considered only in contexts where its specific feature set, such as the 256-bit bus or the 1:1 FP16 rate, is required, but the benchmark scores do not support a performance-based argument for it.

The power draw difference is worth emphasizing. The Intel part delivers a 43.5% higher OpenCL score while consuming 60% less power (60 W versus 150 W). This suggests a generational efficiency leap that the raw specs alone do not fully capture. For portable devices, where both GPUs are designed to operate, the Intel part’s lower TDP is a practical advantage that complements its performance lead.
