AMD Instinct MI308X vs Intel Arc A530M Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark comparisons between the AMD Instinct MI308X and the Intel Arc A530M. The database contains no overlapping benchmark tests for these two accelerators. The AMD Instinct MI308X has no benchmark entries, resulting in an average benchmark score of 0 and a percentile rank of 50 among all GPUs. The Intel Arc A530M, by contrast, has two recorded Geekbench results: an OpenCL score of 49,735 and a Vulkan score of 43,492, producing an average benchmark score of 46,614 and a percentile rank of 85.

Because the MI308X lacks benchmark scores, the comparison rests entirely on architectural and specification differences rather than measured performance. The Arc A530M's percentile placement indicates it outperforms 85 percent of all GPUs in the database, while the MI308X's 50th percentile reflects the absence of recorded results rather than actual performance capability. The Arc A530M's nearest rivals in the database include the AMD Radeon RX 5600M with an average score of 46,601 and a delta of 0 percent, the AMD Radeon RX 6550M with 46,702 and a delta of -0.2 percent, the NVIDIA RTX A2000 with 46,043 and a delta of 1.2 percent, and the NVIDIA RTX 5880 Ada Generation with 45,972 and a delta of 1.4 percent. These deltas show the Arc A530M sits essentially level with the RX 5600M, marginally behind the RX 6550M, and slightly ahead of the two NVIDIA workstation parts.

Where Each One Wins

The Intel Arc A530M wins in every measured category because it is the only one with recorded benchmarks. Its Geekbench OpenCL score of 49,735 and Vulkan score of 43,492 demonstrate functional compute and graphics API support. The MI308X records no wins in the database, with winsA equal to 0 and winsB equal to 0 for the head-to-head set, meaning neither part has a direct victory in a shared test.

The Arc A530M also wins on software compatibility. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it suitable for graphics workloads and modern gaming APIs. The MI308X lists no API support for DirectX, OpenGL, or Vulkan, which aligns with its role as a compute-focused accelerator with no display outputs. The Arc A530M's display outputs are marked as "Portable Device Dependent," indicating it can drive displays in mobile systems, whereas the MI308X has no outputs at all.

In terms of efficiency, the Arc A530M delivers its 3.994 TFLOPS FP32 performance at a 65 W TDP, while the MI308X consumes 750 W for its 81.72 TFLOPS FP32. The Arc A530M's power draw is dramatically lower, and its IGP slot width means it integrates into a system without a discrete power connector. The MI308X uses an OAM Module slot width and has no power connectors listed, relying on the baseboard for power delivery.

Architecture Differences

The MI308X uses the CDNA 3.0 architecture on TSMC's 5 nm process, with the Aqua Vanjaram chip. It contains 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4 million per mm². The Arc A530M uses the Xe-HPG architecture on TSMC's 6 nm process, with the DG2-256 chip. It contains 11,500 million transistors on a 269 mm² die, for a density of 42.8 million per mm². The MI308X's transistor density is more than three times higher, reflecting the newer process node and larger chip.

Memory configurations differ substantially. The MI308X has 192 GB of HBM3 memory on an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The Arc A530M has 8 GB of GDDR6 memory on a 128-bit bus, providing 224.0 GB/s. The MI308X's memory bandwidth is over 23 times higher, and its bus width is 64 times wider. Memory clock rates also differ: the MI308X runs at 1300 MHz with 5.2 Gbps effective, while the Arc A530M runs at 1750 MHz with 14 Gbps effective.

Compute resources are heavily skewed toward the MI308X. It has 19,456 shading units, 1,216 texture mapping units, and no ROPs, yielding a texture rate of 2,553.6 GTexel/s and a pixel rate of 0 MPixel/s. The Arc A530M has 1,536 shading units, 96 TMUs, and 48 ROPs, producing 124.8 GTexel/s and 62.40 GPixel/s. The MI308X lacks dedicated ray tracing cores, while the Arc A530M includes 12 RT cores. Neither part lists tensor cores.

FP32 throughput is 81.72 TFLOPS for the MI308X versus 3.994 TFLOPS for the Arc A530M, a 20.5x difference. FP16 performance is 81.72 TFLOPS (1:1) for the MI308X, while the Arc A530M achieves 7.987 TFLOPS (2:1), meaning the MI308X's FP16 is 10.2x higher. The MI308X supports a 1:1 FP32 to FP16 ratio, while the Arc A530M uses a 2:1 ratio, indicating the Intel part has half-rate FP16.

The bus interfaces differ: the MI308X uses PCIe 5.0 x16, while the Arc A530M uses PCIe 4.0 x8. The MI308X requires a suggested power supply of 1150 W, while the Arc A530M lists no suggested PSU. The MI308X has no power connectors, and the Arc A530M has no power connector data, but the Arc's 65 W TDP allows it to draw power from the motherboard.

Release dates show the MI308X launched on December 5, 2023, while the Arc A530M launched on July 31, 2023. The MI308X's predecessor is Radeon Instinct, and it has no successor. The Arc A530M has no predecessor and is marked as active in production, while the MI308X has no production status listed.

The Verdict

The data indicates the Intel Arc A530M is the only one of the two with measurable performance in the database. Its Geekbench OpenCL and Vulkan scores place it at the 85th percentile, with performance essentially matching the AMD Radeon RX 5600M and slightly trailing the RX 6550M. It supports modern graphics APIs, includes ray tracing cores, and operates at a low 65 W TDP, making it suitable for portable systems with display outputs.

The AMD Instinct MI308X offers vastly higher compute resources: 20.5x the FP32 throughput, over 23x the memory bandwidth, and 24x the memory capacity. Its 192 GB HBM3 pool and 5.32 TB/s bandwidth target large-scale compute workloads, but it has no display outputs, no graphics API support, and no recorded benchmarks. Its 750 W TDP and OAM Module form factor indicate a data center accelerator rather than a client graphics product.

The choice depends on the workload. For graphics rendering, gaming, or mobile deployments requiring API support and display connectivity, the Arc A530M is the functional option. For raw compute throughput, massive memory capacity, and extreme bandwidth in a server environment, the MI308X is the more capable hardware, though its actual performance cannot be quantified from the database because no benchmark scores exist.
