AMD Radeon Instinct MI25 vs Intel Arc A530M Comparison

Head-to-Head Benchmarks

The single recorded head-to-head benchmark places these two GPUs far apart. In Geekbench OpenCL, the AMD Radeon Instinct MI25 scores 68,562 against the Intel Arc A530M's 49,735. That is a 37.9% advantage for the AMD part, a decisive margin in compute workloads. The MI25 wins the only direct comparison in the database, giving it a 1-0 record over the Arc A530M.

Context from the nearest rivals sharpens the picture. The MI25 sits at the 90th percentile of all GPUs in the database, while the Arc A530M sits at the 85th. The MI25's average benchmark score is 68,562, placing it just 0.4% behind the Intel Arc A770 (68,809) and 0.6% behind the NVIDIA CMP 90HX (69,000). It trails the AMD Radeon Pro WX 8200 (69,870) by 1.9% and the NVIDIA Quadro P6000 (69,986) by 2%. These are tiny gaps, all within 2% of the MI25's result. The data shows a GPU that is essentially at parity with a cluster of high-end workstation and mining cards from the previous era.

The Arc A530M, by contrast, has an average benchmark score of 46,614, which is pulled down by its Vulkan result of 43,492 versus its OpenCL result of 49,735. Its nearest rival is the AMD Radeon RX 5600M at 46,601, a 0% delta, meaning the two are statistically identical. It is 0.2% behind the AMD Radeon RX 6550M (46,702), while it leads the NVIDIA RTX A2000 (46,043) by 1.2% and the NVIDIA RTX 5880 Ada Generation (45,972) by 1.4%. The Arc A530M is therefore clustered with mid-range mobile GPUs, not with the high-end desktop parts that the MI25 competes against.

The OpenCL gap of 37.9% is the headline number. It is not a close contest. The MI25's 12.29 TFLOPS of FP32 throughput and 436.2 GB/s of memory bandwidth simply overwhelm the Arc A530M's 3.994 TFLOPS and 224.0 GB/s. In raw compute, the AMD part is in a different tier. The Arc A530M does have a Vulkan score recorded, which the MI25 lacks, but no Vulkan comparison exists in the database, so no direct verdict can be drawn from that API.

Architecture Differences

The two GPUs come from completely different design philosophies and eras. The AMD Radeon Instinct MI25 uses the Vega 10 chip built on GCN 5.0 architecture, manufactured on a 14 nm process at GlobalFoundries. The Intel Arc A530M uses the DG2-256 chip built on Xe-HPG architecture, manufactured on a 6 nm process at TSMC. The process node difference is stark: 14 nm versus 6 nm. That does not translate into a transistor count advantage for Intel, however. The MI25 packs 12,500 million transistors on a 495 mm² die, while the Arc A530M packs 11,500 million transistors on a 269 mm² die. The density figures tell the story: the Intel chip reaches 42.8 million transistors per mm², while the AMD chip manages 25.3 million per mm². Intel's process advantage allows a much smaller die with nearly the same transistor count.

The memory subsystems are entirely different. The MI25 uses 16 GB of HBM2 on a 2048-bit bus, delivering 436.2 GB/s of bandwidth. The Arc A530M uses 8 GB of GDDR6 on a 128-bit bus, delivering 224.0 GB/s. The MI25 has double the memory capacity and roughly double the bandwidth. The memory clock figures reflect the different technologies: the MI25 runs at 852 MHz with 1704 Mbps effective, while the Arc A530M runs at 1750 MHz with 14 Gbps effective. GDDR6 operates at a much higher clock, but the narrow bus cannot compensate for the HBM2's wide interface.

Compute resources also differ sharply. The MI25 has 4096 shading units, 256 TMUs, and 64 ROPs. The Arc A530M has 1536 shading units, 96 TMUs, and 48 ROPs. The MI25 has nearly three times the shading units and more than double the TMUs. The pixel rate is 96.00 GPixel/s for the MI25 versus 62.40 GPixel/s for the Arc A530M. The texture rate is 384.0 GTexel/s versus 124.8 GTexel/s. The FP32 throughput is 12.29 TFLOPS for the MI25 and 3.994 TFLOPS for the Arc A530M. The FP16 figures are 24.58 TFLOPS for the MI25 and 7.987 TFLOPS for the Arc A530M, both at a 2:1 ratio. The MI25 is the compute monster; the Arc A530M is a mid-range mobile part.

The Arc A530M does have one structural feature the MI25 lacks: 12 ray tracing cores. The MI25 has no ray tracing hardware at all, as it predates that feature in AMD's data center lineup. The Arc A530M also supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the MI25 supports DirectX 12 (12_1) and Vulkan 1.3. Both support OpenGL 4.6. The Intel part is newer and carries the API feature set of its generation.

The power and physical profiles are opposites. The MI25 is a 300 W dual-slot card requiring two 8-pin power connectors and a 700 W suggested power supply. It measures 267 mm in length and 111 mm in height. The Arc A530M is a 65 W mobile IGP with no power connectors and no suggested PSU, and its dimensions are listed as portable device dependent. The MI25 has no display outputs; the Arc A530M's outputs are portable device dependent. The MI25 uses PCIe 3.0 x16, while the Arc A530M uses PCIe 4.0 x8. The production statuses reflect their lifecycles: the MI25 is end-of-life, released in 2017, while the Arc A530M is active, released in 2023.

The Verdict

The data supports a clear split by use case. For compute-heavy workloads, the AMD Radeon Instinct MI25 is the stronger part. Its 37.9% OpenCL lead over the Arc A530M, its 90th percentile ranking, and its near-parity with the Intel Arc A770 and NVIDIA CMP 90HX all point to a GPU that was designed for data center compute and still holds its own. The 12.29 TFLOPS FP32 figure and 436.2 GB/s of bandwidth put it in a different performance class. Anyone running OpenCL workloads on a desktop workstation should favor the MI25, provided the 300 W power draw and dual-slot footprint are acceptable.

For mobile or power-constrained systems, the Arc A530M is the only viable choice. It is a 65 W IGP with no external power connectors, designed to be embedded in a laptop or portable device. The MI25 has no display outputs and cannot be used in such a system at all. The Arc A530M also offers ray tracing cores and DirectX 12 Ultimate support, features the MI25 lacks entirely. For gaming or modern graphics features in a portable chassis, the Arc A530M is the pick.

The database does not show a mixed-use scenario where the Arc A530M wins a direct compute comparison. Its nearest rivals are the AMD Radeon RX 5600M and RX 6550M, both mobile mid-range parts, and it sits at the 85th percentile. The MI25 sits at the 90th percentile. The verdict is simple: the MI25 wins on raw compute, the Arc A530M wins on efficiency, portability, and modern API support. Pick the MI25 for a stationary compute box. Pick the Arc A530M for a laptop or a compact embedded system.
