Intel Arc A580 vs Intel Arc Graphics 2 Xe Mobile Comparison

Intel Arc A580 is a discrete desktop graphics card built on the Xe-HPG architecture, while Intel Arc Graphics 2 Xe Mobile is an integrated GPU based on the newer Xe3-LPG architecture. The database places the A580 in the 87th percentile of all GPUs, while the mobile part sits at the 50th percentile. The A580 has an average benchmark score of 57,756, whereas the mobile GPU has no recorded benchmark scores, giving it a database average of zero. This creates a clear performance hierarchy, but the two parts serve fundamentally different roles in a system.

Where Each One Wins

The Intel Arc A580 wins in every scenario where raw compute and rendering throughput matter. Its 12.29 TFLOPS of FP32 performance and 512.0 GB/s of memory bandwidth put it in a different class from the mobile part. The A580 is designed for desktop gaming and content creation, with a 175 W TDP and dedicated 8 GB GDDR6 memory on a 256-bit bus. It supports PCIe 4.0 x16 and draws power from two 8-pin connectors, making it a full-size, dual-slot expansion card.

The Intel Arc Graphics 2 Xe Mobile wins in efficiency and integration. It uses a 3 nm process node from Intel, compared to the 6 nm TSMC node used by the A580. Its 25 W TDP is a fraction of the desktop card's power draw, and it requires no power connectors and no expansion slot, appearing as an IGP in the system. The mobile part boosts to 2500 MHz, which is higher than the A580's 2000 MHz boost clock, but with only 256 shading units versus 3072, its total throughput is far lower.

The data indicates the A580 is the only one of the two with measurable benchmark results. The mobile GPU has no entries in the database, so its wins are limited to architectural efficiency, process technology, and system integration. For any workload that produces a score, the A580 is the clear winner.

Architecture Differences

The two GPUs come from different generations of Intel graphics technology. The Arc A580 uses the DG2-512 chip with the Xe-HPG architecture, belonging to the Alchemist generation within the Arc 5 product tier. It is built on a 6 nm process at TSMC, packing 21,700 million transistors into a 406 mm² die, for a transistor density of 53.4 million per square millimeter.

The Arc Graphics 2 Xe Mobile uses the Wildcat Lake chip with the Xe3-LPG architecture, belonging to the Arc Graphics-M generation. It is built on a 3 nm process at Intel's own foundry, though its transistor count and die size are listed as unknown in the database. The architecture is newer, and the process node is significantly more advanced, but the chip is much smaller in terms of execution resources.

The A580 has 3072 shading units, 192 texture mapping units, and 96 raster output units. It also includes 24 ray tracing cores. The mobile part has 256 shading units, 16 TMUs, and 8 ROPs, with just 2 ray tracing cores. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so feature-level API support is identical.

Memory architecture differs completely. The A580 uses dedicated 8 GB GDDR6 memory at 2000 MHz with a 256-bit bus, delivering 512.0 GB/s of bandwidth. The mobile GPU uses system shared memory, with the bus width and bandwidth marked as system dependent. This means the mobile part's memory performance varies with the host system's RAM configuration.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs. The A580 has three recorded scores: 2229 in 3DMark Steel Nomad DX12, 91657 in Geekbench OpenCL, and 79381 in Geekbench Vulkan. The Arc Graphics 2 Xe Mobile has no benchmark scores at all, so no direct comparison is possible from the recorded data.

The A580's average benchmark score of 57756 places it near several competitors. It trails the AMD Radeon RX 5600 OEM by 0.6 percent, sits 0.7 percent ahead of the AMD Radeon RX 9070 GRE, leads the Intel Arc A570M by 0.8 percent, and beats the AMD Radeon RX 6950 XT by 1.1 percent. These margins are small, indicating the A580 lands in a tightly contested performance tier.

Given the mobile GPU's lack of recorded scores, the performance gap must be inferred from specifications. The A580 delivers 12.29 TFLOPS of FP32 compute, while the mobile part delivers 1,280.0 GFLOPS, which is 1.28 TFLOPS. That puts the A580 at roughly 9.6 times the raw FP32 throughput. Pixel rate is 192.0 GPixel/s versus 20.00 GPixel/s, a 9.6x difference. Texture rate is 384.0 GTexel/s versus 40.00 GTexel/s, again a 9.6x gap. These ratios are consistent across all throughput metrics.

FAQ

Q: Which GPU has more shading units?

A: The Intel Arc A580 has 3072 shading units, while the Intel Arc Graphics 2 Xe Mobile has only 256.

Q: What is the memory bandwidth difference?

A: The A580 has 512.0 GB/s of dedicated GDDR6 bandwidth. The mobile GPU uses system shared memory with system dependent bandwidth, which is not quantified in the database.

Q: Do both GPUs support ray tracing?

A: Yes, both support DirectX 12 Ultimate (12_2), which includes ray tracing. The A580 has 24 ray tracing cores, while the mobile part has 2.

Q: What are the power requirements for each?

A: The A580 has a 175 W TDP and requires a 450 W suggested power supply, using two 8-pin connectors. The mobile GPU has a 25 W TDP, no power connectors, and no suggested PSU.

Q: How do the process nodes compare?

A: The A580 is built on TSMC's 6 nm process. The Arc Graphics 2 Xe Mobile is built on Intel's 3 nm process, which is a more advanced node.

Q: Which GPU has a higher boost clock?

A: The mobile part boosts to 2500 MHz, which is higher than the A580's 2000 MHz boost clock. However, the A580 has far more execution resources, so its total throughput is much higher.

The Verdict

The data clearly shows the Intel Arc A580 is the superior performer for any workload that generates a benchmark score. Its average score of 57756, 87th percentile ranking, and 12.29 TFLOPS of FP32 compute place it firmly in the discrete desktop GPU tier. It competes within a few percentage points of cards like the AMD Radeon RX 5600 OEM and the AMD Radeon RX 9070 GRE, making it a viable option for gaming and compute tasks.

The Intel Arc Graphics 2 Xe Mobile is not a competitor in raw performance. Its 50th percentile ranking and lack of any recorded benchmark scores confirm that it serves a different purpose. The 25 W TDP, system shared memory, and IGP form factor make it suitable for thin-and-light laptops where power efficiency and integration matter more than frame rates.

Architecturally, the mobile part is more advanced, using the newer Xe3-LPG design on a 3 nm Intel process. But the A580 compensates with a much larger chip, 12 times the shading units, and dedicated high-bandwidth memory. For desktop users building a gaming or content creation system, the A580 is the only practical choice. For portable systems where battery life and thermal constraints dominate, the mobile GPU is the appropriate solution. The two parts are not direct rivals; they address different market segments with different priorities.
