AMD Radeon RX Vega 56 vs Intel Arc A530M Comparison

The Intel Arc A530M and AMD Radeon RX Vega 56 occupy different corners of the GPU landscape. The Arc A530M is a modern, power-efficient mobile part built on a 6 nm process, while the RX Vega 56 is a larger, older desktop card from 2017 on a 14 nm node. Benchmark data from the database shows these two GPUs do not share any common test workloads, so a direct head-to-head comparison must rely on their respective average scores and percentile rankings rather than identical benchmarks. The recorded average benchmark score for the Intel Arc A530M is 46614, placing it in the 85th percentile of all GPUs. The AMD Radeon RX Vega 56 has an average score of 37507, placing it in the 81st percentile. This indicates that, on average, the Arc A530M outperforms the RX Vega 56 by a significant margin, roughly 24% higher based on these aggregate scores. However, the RX Vega 56 has a higher peak performance in specific workloads, as detailed below.

Head-to-Head Benchmarks

The database does not contain any overlapping benchmark tests between the Intel Arc A530M and the AMD Radeon RX Vega 56. The Arc A530M has recorded scores for Geekbench OpenCL and Geekbench Vulkan, while the RX Vega 56 has scores for 3DMark Steel Nomad DX12 and Geekbench Metal. This lack of common tests means a direct comparison per benchmark is impossible. Instead, we can compare their overall average scores. The Arc A530M’s average score of 46614 is substantially higher than the RX Vega 56’s 37507, representing a 24.3% advantage for the Intel part. This is a clear win in aggregate performance, suggesting that across a broad range of potential workloads, the Arc A530M is the faster GPU.

Looking at individual recorded scores, the Arc A530M achieves 49735 in Geekbench OpenCL and 43492 in Geekbench Vulkan. The RX Vega 56 achieves 73512 in Geekbench Metal and 1501 in 3DMark Steel Nomad DX12. While these tests are not directly comparable, the Geekbench Metal score for the RX Vega 56 is notably high, exceeding any single score recorded for the Arc A530M. This indicates that in Metal-based applications, particularly those optimized for macOS or iOS environments, the RX Vega 56 can deliver very high performance. Conversely, the Arc A530M’s Vulkan score of 43492 suggests strong cross-platform performance in Vulkan-based games and compute workloads.

The nearest rivals for the Arc A530M include the AMD Radeon RX 5600M, which has a nearly identical average score of 46601, a difference of 0%. The NVIDIA RTX A2000 scores 46043, putting it 1.2% behind the Arc A530M. The AMD Radeon RX 6550M scores 46702, a 0.2% advantage over the Arc. For the RX Vega 56, its nearest rivals include the NVIDIA Tesla P4 at 37628, which is 0.3% ahead, and the NVIDIA GeForce RTX 4070 at 37648, 0.4% ahead. The AMD Radeon PRO W6400 scores 37157, 0.9% behind, and the NVIDIA GeForce RTX 4080 Mobile scores 38135, 1.6% ahead. These rival comparisons show that the Arc A530M is competitive with modern mid-range GPUs, while the RX Vega 56 sits in a lower performance tier, close to older or lower-end parts.

Where Each One Wins

The Intel Arc A530M wins decisively on aggregate performance. Its average benchmark score of 46614 is nearly 25% higher than the RX Vega 56’s 37507. This suggests that for general-purpose computing, including gaming, content creation, and compute tasks that use OpenCL or Vulkan, the Arc A530M is the stronger choice. The Arc’s 85th percentile ranking versus the RX Vega 56’s 81st percentile further reinforces this. The data indicates that the Arc A530M is a more capable GPU for most modern workloads, especially those that leverage DirectX 12 Ultimate features, as it supports the 12_2 API level. The RX Vega 56 only supports DirectX 12 (12_1), which means it lacks some of the newest rendering features like mesh shaders and variable rate shading that are available on the Arc.

The AMD Radeon RX Vega 56, however, shows a clear strength in Metal-based applications. Its Geekbench Metal score of 73512 is far above any single benchmark result for the Arc A530M. This is likely due to the RX Vega 56’s older architecture having mature Metal drivers, or the specific test favoring its high memory bandwidth. For users who rely on Metal, such as those in Apple’s ecosystem, the RX Vega 56 would be the superior option. Additionally, the RX Vega 56 has a much higher theoretical peak performance in raw throughput metrics, such as its FP32 rate of 10.54 TFLOPS versus the Arc’s 3.994 TFLOPS. However, these raw numbers do not translate to higher average benchmark scores, indicating that real-world performance is limited by other factors such as software optimization and power constraints.

The RX Vega 56 also wins on memory bandwidth. Its HBM2 memory provides 409.6 GB/s of bandwidth, compared to the Arc A530M’s 224.0 GB/s. This massive bandwidth advantage could be beneficial in memory-intensive workloads like 4K texture streaming or certain compute tasks. The RX Vega 56’s 2048-bit memory bus is also much wider than the Arc’s 128-bit bus. However, the Arc A530M has a faster effective memory speed of 14 Gbps versus the RX Vega’s 1600 Mbps, though the latter’s HBM2 technology compensates with higher bandwidth per pin.

Architecture Differences

The architectural gap between these two GPUs is substantial. The Intel Arc A530M is built on the Xe-HPG architecture, specifically the DG2-256 chip, manufactured on a 6 nm process at TSMC. It contains 11,500 million transistors on a die size of 269 mm², resulting in a transistor density of 42.8 million per mm². This is a modern, efficient design. The RX Vega 56 uses the older GCN 5.0 architecture, with the Vega 10 chip, manufactured on a 14 nm process at GlobalFoundries. It has 12,500 million transistors on a much larger die of 495 mm², giving a lower transistor density of 25.3 million per mm². The Arc’s smaller, denser chip is a clear sign of its newer manufacturing technology.

In terms of core configuration, the Arc A530M has 1536 shading units, 96 texture mapping units, and 48 render output units. It also includes 12 ray tracing cores, a feature the RX Vega 56 completely lacks. The RX Vega 56 has 3584 shading units, 224 TMUs, and 64 ROPs, which are significantly higher numbers. This gives the RX Vega a theoretical compute advantage, but the Arc’s architecture is more efficient. The Arc supports DirectX 12 Ultimate (12_2), while the RX Vega only supports DirectX 12 (12_1). Both support OpenGL 4.6, but the Arc supports Vulkan 1.4 while the RX Vega supports Vulkan 1.3, indicating newer API support on the Intel part.

The memory subsystems are vastly different. The Arc A530M uses 8 GB of GDDR6 memory on a 128-bit bus, with a bandwidth of 224.0 GB/s. The RX Vega 56 uses 8 GB of HBM2 memory on a 2048-bit bus, providing 409.6 GB/s of bandwidth. This is a major architectural difference, with the RX Vega offering nearly double the memory bandwidth. The power requirements also diverge sharply. The Arc A530M has a TDP of 65 W and is designed as an integrated GPU (IGP), meaning it does not require a separate power connector or a suggested PSU. The RX Vega 56 has a TDP of 210 W, requires dual 8-pin power connectors, and a suggested 550 W PSU. This makes the Arc far more suitable for thin laptops, while the RX Vega is a power-hungry desktop card.

The Verdict

Based on the recorded data, the Intel Arc A530M is the superior GPU for the majority of users. Its average benchmark score of 46614 is significantly higher than the RX Vega 56’s 37507, and it ranks in the 85th percentile of all GPUs compared to the RX Vega’s 81st percentile. The Arc also offers modern features like ray tracing, DirectX 12 Ultimate support, and a far lower power draw of 65 W versus 210 W. For anyone building a new system, especially a laptop, the Arc A530M is the clear choice. Its performance is competitive with recent GPUs like the AMD Radeon RX 5600M and NVIDIA RTX A2000, as shown in its nearest rivals list.

The AMD Radeon RX Vega 56, however, still has a niche. Its Geekbench Metal score of 73512 is exceptional, and its memory bandwidth of 409.6 GB/s is more than double the Arc’s. For users who prioritize Metal-based workloads or require extremely high memory bandwidth for specific compute tasks, the RX Vega 56 could be the better option. Its raw FP32 throughput of 10.54 TFLOPS also exceeds the Arc’s 3.994 TFLOPS, though this does not translate to better average benchmark performance. The RX Vega 56 is also end-of-life, meaning no further driver optimizations are likely, whereas the Arc is still active in production. For most tasks, the Arc A530M wins. For specialized, memory-heavy or Metal-specific applications, the RX Vega 56 has advantages that cannot be ignored.
