AMD Radeon RX 7900M vs Intel Arc A580 Comparison

The Verdict

The recorded data makes the separation between these two GPUs unusually clear. The AMD Radeon RX 7900M wins every recorded head-to-head benchmark, with deltas ranging from 41.3% to 100% depending on the test. If you are choosing purely on measured performance, the RX 7900M is the decisive pick. It sits at the 94th percentile among all GPUs in the database, while the Intel Arc A580 sits at the 87th percentile. That gap is not trivial; it places them in different performance tiers entirely.

However, the Arc A580 is not a bad card in isolation. Its average benchmark score of 57,756 places it within a close pack of rivals: the AMD Radeon RX 5600 OEM (58,085, a 0.6% difference), the AMD Radeon RX 9070 GRE (57,367, a 0.7% difference), and the Intel Arc A570M (58,239, a 0.8% difference) are all within roughly one percent. The RX 6950 XT is also nearby at 58,392, trailing by 1.1%. This suggests the A580 is a solid mainstream performer that trades blows with those specific cards. The RX 7900M, by contrast, sits near the AMD Radeon Pro VII (97,131, a 0.4% difference) and the NVIDIA Quadro RTX 6000 (101,872, a 4.3% deficit). It is a high-end part, closer to workstation-class silicon than to the A580's segment.

Who should pick which? If you need maximum frame rates, high-resolution rendering, or compute-heavy workloads, the RX 7900M is the only choice from this data. Its 16 GB memory, higher raw throughput, and 94th percentile ranking make it the clear performance leader. If you are constrained by power, cooling, or physical space, the Arc A580 might be the practical pick: it is a dual-slot card with a 175 W TDP, while the RX 7900M is an integrated graphics package (IGP) with a 180 W TDP, meaning you would need a laptop or a platform that supports that form factor. But on pure benchmark results, there is no contest. The RX 7900M wins all three recorded tests, and the margin is often massive.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The AMD Radeon RX 7900M uses the Navi 31 chip, built on RDNA 3.0 architecture, with the codename Plum Bonito. It is part of the Navi Mobile (RX 7000M) generation. The Intel Arc A580 uses the DG2-512 chip, built on Xe-HPG architecture, from the Alchemist (Arc 5) generation. These are fundamentally different designs: AMD's RDNA 3.0 targets mobile high-performance with a dense 5 nm process, while Intel's Xe-HPG targets desktop discrete GPUs with a 6 nm process.

The manufacturing details highlight the difference in scale. The RX 7900M is fabricated on a 5 nm process at TSMC, with 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1 million per mm². The Arc A580 uses a 6 nm process at TSMC, with 21,700 million transistors on a 406 mm² die, for a density of 53.4 million per mm². The RX 7900M packs more than twice the transistors into a larger die with a much higher density. That density advantage is a direct result of the newer, finer process node.

Ray tracing hardware also differs sharply. The RX 7900M has 72 ray tracing cores, while the Arc A580 has 24. This is a 3x difference in dedicated RT hardware, which explains why the RX 7900M might handle ray-traced workloads with more headroom, though the recorded benchmarks do not directly test RT performance. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the API feature set is identical, but the underlying hardware capability is not.

The form factor is another architectural distinction. The RX 7900M is listed as an IGP (integrated graphics package) with no power connectors and portable-device-dependent display outputs. It is designed to be soldered onto a laptop board. The Arc A580 is a dual-slot desktop card with two 8-pin power connectors and a suggested 450 W power supply. This is not just a performance difference; it is a fundamental platform difference. You cannot put an RX 7900M into a desktop PCIe slot as a standalone card, and you cannot easily integrate an Arc A580 into a thin laptop.

Specification Differences

The specification sheet shows where the two diverge, beyond just the benchmark scores. The RX 7900M has a base clock of 1825 MHz and a boost clock of 2090 MHz, while the Arc A580 runs at 1700 MHz base and 2000 MHz boost. The RX 7900M is faster at both ends, but the gap narrows at boost: 90 MHz, or about 4.5%. The memory clock also differs: the RX 7900M runs at 2250 MHz (18 Gbps effective), while the Arc A580 runs at 2000 MHz (16 Gbps effective). This feeds into the bandwidth difference already noted: 576.0 GB/s versus 512.0 GB/s.

Compute resources are significantly different. The RX 7900M has 4,608 shading units, 288 texture mapping units, and 192 render output units. The Arc A580 has 3,072 shading units, 192 TMUs, and 96 ROPs. The RX 7900M has 50% more shading units, 50% more TMUs, and double the ROPs. This translates directly to pixel and texture rates: the RX 7900M delivers 401.3 GPixel/s and 601.9 GTexel/s, while the Arc A580 delivers 192.0 GPixel/s and 384.0 GTexel/s. The RX 7900M is more than twice as fast in pixel fill and about 57% faster in texture fill.

Floating-point performance tells a similar story. The RX 7900M delivers 38.52 TFLOPS in FP32 and 77.05 TFLOPS in FP16 (2:1). The Arc A580 delivers 12.29 TFLOPS in FP32 and 24.58 TFLOPS in FP16 (2:1). The RX 7900M is roughly 3.1x faster in FP32 and FP16. This is a massive compute advantage, which likely explains the large Geekbench OpenCL and Vulkan deltas.

Power and physical specs are where the Arc A580 pulls back. The RX 7900M has a 180 W TDP, while the Arc A580 has a 175 W TDP, a difference of only 5 W. The Arc A580 is a dual-slot card with a 450 W suggested PSU, while the RX 7900M is an IGP with no power connectors. The bus interface is the same (PCIe 4.0 x16), and both are marked as Active in production. The release dates are close: the RX 7900M launched on October 18, 2023, and the Arc A580 on October 9, 2023, just nine days apart. The Arc A580 has a successor listed (Battlemage), while the RX 7900M does not.

Head-to-Head Benchmarks

The head-to-head data is unambiguous. In the 3DMark Steel Nomad DX12 test, the RX 7900M scores 4,201 against the Arc A580's 2,229. That is an 88.5% delta in favor of AMD. This is a synthetic DirectX 12 benchmark that stresses modern rendering paths, and the RX 7900M nearly doubles the A580's result.

In Geekbench OpenCL, the RX 7900M scores 129,499, while the Arc A580 scores 91,657. The delta is 41.3%, which is the smallest margin of the three tests but still a decisive win. OpenCL is compute-oriented, and the RX 7900M's higher FP32 and FP16 throughput gives it a clear edge. The A580's result is not embarrassing; it is within the range of its nearest rivals, but it cannot match the AMD part.

The largest gap appears in Geekbench Vulkan. The RX 7900M scores 158,760, more than double the Arc A580's 79,381. That is a 100% delta, meaning the RX 7900M is exactly twice as fast in this Vulkan compute test. Vulkan is a low-level API that can expose raw hardware throughput, and the RX 7900M's combination of more shading units, higher clocks, and double the memory bandwidth shows up here.

The RX 7900M wins all three tests, with an average delta across the suite of roughly 76.6%. The Arc A580's best showing is in OpenCL, where it trails by 41.3%, but even that is a substantial gap. For any workload that these benchmarks represent, the RX 7900M is the faster card by a wide margin.

Where Each One Wins

The RX 7900M wins every recorded benchmark, so the "where each one wins" section is mostly about the degree of the win and the context. In 3DMark Steel Nomad, the RX 7900M's 88.5% lead suggests it is far better suited for modern DirectX 12 gaming workloads, particularly at higher resolutions where pixel fill and memory bandwidth matter. Its 16 GB memory and 576.0 GB/s bandwidth give it headroom for large textures and heavy geometry, while the A580's 8 GB and 512.0 GB/s might bottleneck in those scenarios.

In compute-heavy tasks like OpenCL and Vulkan, the RX 7900M's advantage is even more pronounced (41.3% and 100% respectively). This points to applications such as rendering, machine learning inference, or scientific compute where raw FP32 and FP16 throughput are the limiting factors. The RX 7900M's 38.52 TFLOPS FP32 and 77.05 TFLOPS FP16 are roughly triple the A580's figures, so any workload that scales with shader count or ray tracing cores will favor the AMD part.

The Arc A580 does have a niche, but it is not based on performance wins. Its dual-slot form factor, 175 W TDP, and 450 W suggested PSU make it a straightforward drop-in for existing desktop builds with standard power supplies. The RX 7900M, as an IGP with no power connectors, requires a platform that supports it, typically a high-end laptop. If you are upgrading an older desktop and want a modern GPU with DirectX 12 Ultimate and Vulkan 1.4 support, the Arc A580 is the more practical physical choice. Its average benchmark score of 57,756 puts it in the same league as the RX 5600 OEM and RX 9070 GRE, so it is a capable mainstream card, just not in the RX 7900M's class.

In summary, the RX 7900M wins on every measurable performance axis in the database. The Arc A580 wins on physical integration and power requirements, but the benchmark data does not record a single test where it beats the RX 7900M. Choose the RX 7900M for performance, and the Arc A580 only if your platform dictates a desktop add-in card.
