AMD Instinct MI325X vs Intel Arc A530M Comparison

Where Each One Wins

The recorded data draws a clean line between these two accelerators. The AMD Instinct MI325X is a data center compute module with no display outputs, no graphics API support, and a pixel rate of 0 MPixel/s. Its entire design targets raw throughput for server workloads. The Intel Arc A530M is a mobile graphics processor with 48 ROPs, a 62.40 GPixel/s pixel rate, DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 support. It is built to render frames and drive portable displays.

Benchmark results confirm the split. The Intel part has two recorded Geekbench scores: 49,735 in OpenCL and 43,492 in Vulkan. The AMD part has no benchmark entries in the database, which means the comparison cannot rely on synthetic test scores for the MI325X. Instead, the wins are structural. The MI325X wins on compute capacity: 81.72 TFLOPS FP32, 81.72 TFLOPS FP16 at a 1:1 ratio, and a texture rate of 2,553.6 GTexel/s. The Arc A530M delivers 3.994 TFLOPS FP32, 7.987 TFLOPS FP16 at a 2:1 ratio, and a texture rate of 124.8 GTexel/s. For FP32 throughput, the MI325X is roughly 20.5 times higher. For FP16, the ratio depends on the mode: the MI325X sustains 81.72 TFLOPS in both precisions, while the Arc reaches 7.987 TFLOPS only in the packed 2:1 path.

The Intel part wins in every graphics-oriented category. It has ROPs, the MI325X has none. It has 12 ray tracing cores, the MI325X lists none. It exposes a full API stack, the MI325X exposes none. It outputs to a portable device, the MI325X has no outputs. The AMD part wins in memory scale: 256 GB of HBM3e across an 8192-bit bus delivering 6.14 TB/s, versus 8 GB of GDDR6 on a 128-bit bus delivering 224.0 GB/s. That is a 32x memory capacity advantage and roughly a 27.4x bandwidth advantage.

Architecture Differences

The MI325X uses the Aqua Vanjaram chip built on TSMC's 5 nm process with CDNA 3.0 architecture. The Arc A530M uses the DG2-256 chip on TSMC's 6 nm process with Xe-HPG architecture, part of the Alchemist generation under the Arc 5 Mobile family. The transistor counts differ by an order of magnitude: 153,000 million for the AMD chip against 11,500 million for the Intel chip. Die size runs 1017 mm² versus 269 mm². Transistor density comes to 150.4M per mm² for the MI325X and 42.8M per mm² for the Arc, so the AMD design packs nearly four times as many transistors per square millimeter despite the larger die.

Memory architecture is fundamentally different. The MI325X uses HBM3e with a 8192-bit interface and 6 Gbps effective signaling at 1500 MHz. The Arc uses GDDR6 with a 128-bit interface and 14 Gbps effective signaling at 1750 MHz. The MI325X has 19456 shading units and 1216 TMUs, while the Arc has 1536 shading units and 96 TMUs. The MI325X lists no ROPs, no ray tracing cores, and no tensor cores; the Arc has 48 ROPs and 12 ray tracing cores. Clock behavior also differs: the MI325X runs a 1000 MHz base and 2100 MHz boost, the Arc runs 900 MHz base and 1300 MHz boost. The AMD module is rated at 1000 W TDP and requires a 1400 W suggested PSU, with no power connectors because it is an OAM Module. The Arc is rated at 65 W TDP and is an IGP with no suggested PSU listed. The interfaces differ as well: PCIe 5.0 x16 for the MI325X, PCIe 4.0 x8 for the Arc. The AMD part has no display outputs; the Intel part's outputs are portable device dependent.

The release dates reflect different market timing. The MI325X launched on 2024-10-09, the Arc A530M on 2023-07-31. The MI325X belongs to the Instinct (MIx) generation and lists "Radeon Instinct" as its predecessor. The Arc has no predecessor listed and is marked as Active in production status, while the MI325X has no production status recorded.

Head-to-Head Benchmarks

No head-to-head benchmark entries exist in the database for this pair. The only recorded benchmark data belongs to the Intel Arc A530M, which scores 49,735 in Geekbench OpenCL and 43,492 in Geekbench Vulkan. Its average benchmark score is 46,614, placing it at the 85th percentile of all GPUs. The MI325X has an average benchmark score of 0 and sits at the 50th percentile, because no benchmark runs have been recorded for it.

The Arc A530M's nearest rivals provide context for its performance class. The AMD Radeon RX 5600M scores 46,601, a 0% delta. The AMD Radeon RX 6550M scores 46,702, which is 0.2% higher than the Arc's average. The NVIDIA RTX A2000 scores 46,043, putting the Arc 1.2% ahead. The NVIDIA RTX 5880 Ada Generation scores 45,972, putting the Arc 1.4% ahead. These deltas show the Arc A530M sits in a narrow performance band around 46,000 to 46,700 points, slightly ahead of two NVIDIA workstation parts and essentially tied with two AMD mobile parts.

The MI325X cannot be placed on that curve. With no benchmark scores, its percentile of 50 is a default value, not a measured result. The meaningful comparison comes from specification data. The FP32 gap is 81.72 TFLOPS versus 3.994 TFLOPS. The memory bandwidth gap is 6.14 TB/s versus 224.0 GB/s. The texture rate gap is 2,553.6 GTexel/s versus 124.8 GTexel/s. The Intel part's only compute advantage is FP16 efficiency in its packed path: 7.987 TFLOPS from a 65 W TDP, versus 81.72 TFLOPS from a 1000 W TDP. Per watt, the Arc delivers roughly 0.123 TFLOPS per watt in FP16, while the MI325X delivers about 0.0817 TFLOPS per watt in FP16. Per watt in FP32, the Arc delivers about 0.0614 TFLOPS per watt, the MI325X about 0.0817 TFLOPS per watt. The AMD part still wins FP32 efficiency, but the Intel part wins FP16 efficiency when using the packed 2:1 path.

The Arc A530M's 85th percentile ranking indicates it outperforms most recorded GPUs in the database, despite its modest 3.994 TFLOPS FP32 figure. Its nearest rivals all sit within 1.4% of its average score, confirming that the Alchemist mobile chip lands in a competitive midrange segment. The MI325X has no comparable ranking data, so its percentile cannot be interpreted as a performance measure.

The Verdict

The data separates these two products by role, not by quality. The AMD Instinct MI325X is a server accelerator with 256 GB of HBM3e, 81.72 TFLOPS FP32, and no graphics output. The Intel Arc A530M is a mobile graphics processor with 8 GB of GDDR6, 48 ROPs, 12 ray tracing cores, and full API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4.

A user with compute workloads that scale to a 1000 W OAM module and a 1400 W suggested PSU should consider the MI325X. Its 6.14 TB/s memory bandwidth and 81.72 TFLOPS FP16 throughput target large matrix operations and memory-bound inference. The lack of display outputs and graphics APIs is irrelevant in a server context.

A user with a portable device that needs rendering, ray tracing, and standard graphics APIs should consider the Arc A530M. Its 62.40 GPixel/s pixel rate, 124.8 GTexel/s texture rate, and 65 W TDP fit a mobile chassis. The 85th percentile ranking and the near-parity with the RX 5600M, RX 6550M, RTX A2000, and RTX 5880 Ada Generation place it in a recognizable performance tier.

The MI325X has no benchmark scores in the database, so any direct performance ranking must rely on specifications. Those specifications show a compute device with a 20.5x FP32 advantage over the Arc. The Arc has a graphics feature set the MI325X entirely lacks. Neither device can substitute for the other.
