Intel Arc A580 vs NVIDIA RTX A1000 Mobile Comparison

The Intel Arc A580 and NVIDIA RTX A1000 Mobile occupy very different positions in the hardware landscape. The Arc A580 is a desktop discrete graphics card built on Intel’s Xe-HPG architecture, while the RTX A1000 Mobile is a laptop-oriented GPU from NVIDIA’s Ampere generation. Their benchmark data reveals a substantial performance gap, but the nuances of architecture, power, and feature sets make the comparison more complex than raw scores alone.

Head-to-Head Benchmarks

The recorded benchmarks show a decisive advantage for the Intel Arc A580 in every shared test. In Geekbench OpenCL, the Arc A580 scores 91,657, while the RTX A1000 Mobile manages 48,703. That is a delta of 88.2%, meaning the Intel part delivers nearly double the compute throughput in this workload. The margin is slightly narrower in Geekbench Vulkan, where the Arc A580 posts 79,381 against the RTX A1000 Mobile’s 46,782, a 69.7% advantage. Both results underscore a clear generational and segment difference: the desktop card is built for sustained high-performance rendering, while the mobile part is optimized for power-constrained environments.

Context from the database’s average benchmark scores reinforces this gap. The Arc A580 has an average benchmark score of 57,756, placing it in the 87th percentile of all GPUs. The RTX A1000 Mobile averages 47,743, which lands in the 85th percentile. While the percentile difference is only two points, the absolute score gap of nearly 10,000 points is significant. The Arc A580’s nearest rivals include the AMD Radeon RX 5600 OEM (average score 58,085, delta -0.6%), the AMD Radeon RX 9070 GRE (57,367, delta +0.7%), and the Intel Arc A570M (58,239, delta -0.8%). These deltas are small, indicating that the Arc A580 sits in a tightly contested performance band. The RTX A1000 Mobile’s nearest rivals are the AMD Radeon RX 6800 XT (48,477, delta -1.5%), the AMD Radeon RX 6550M (46,702, delta +2.2%), and the Intel Arc A530M (46,614, delta +2.4%). The RTX part leads those competitors by a slim margin, but it trails the Arc A580 by a wide margin.

The head-to-head data records exactly two wins for the Arc A580 and zero for the RTX A1000 Mobile. No shared benchmark favors the NVIDIA part. Even in Vulkan, which often highlights driver efficiency, the Intel card maintains a healthy lead. This suggests the Arc A580’s higher raw compute resources, including more shading units and higher clock speeds, translate directly into superior performance in synthetic workloads.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The Intel Arc A580 uses the DG2-512 chip, built on TSMC’s 6 nm process node. It integrates 21,700 million transistors on a 406 mm² die, yielding a transistor density of 53.4 million per square millimeter. The NVIDIA RTX A1000 Mobile uses the GA107 chip, fabricated on Samsung’s 8 nm node. That chip packs 8,700 million transistors into a 200 mm² die, with a density of 43.5 million per square millimeter. The Intel chip is larger, denser, and produced on a more advanced process, which partially explains its performance advantage.

Architecturally, the Arc A580 is based on Xe-HPG, Intel’s gaming-oriented architecture from the Alchemist generation. The RTX A1000 Mobile is built on Ampere, NVIDIA’s architecture for the Ax000 mobile series. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. However, the internal compute resources differ sharply. The Arc A580 has 3,072 shading units, 192 texture mapping units, 96 raster operations pipelines, and 24 ray tracing cores. The RTX A1000 Mobile has 2,048 shading units, 64 TMUs, 32 ROPs, and 16 ray tracing cores. The Intel card also lacks dedicated tensor cores, while the NVIDIA part includes 64 tensor cores, which are designed for AI acceleration but do not appear in the recorded benchmarks.

Clock speeds further separate the two. The Arc A580 runs at a base clock of 1700 MHz and boosts to 2000 MHz. The RTX A1000 Mobile operates at a much lower 630 MHz base and 1140 MHz boost. This clock disparity is typical for mobile parts, which must manage thermal and power limits, but it also means the Arc A580’s raw throughput is far higher. The FP32 performance tells the story: the Arc A580 delivers 12.29 TFLOPS, while the RTX A1000 Mobile manages 4.669 TFLOPS. The Intel card’s FP16 rate is 24.58 TFLOPS (2:1 ratio), whereas the NVIDIA part achieves 4.669 TFLOPS (1:1 ratio). The 2:1 ratio on the Arc A580 suggests it can double FP16 throughput with packed math, a feature absent from the RTX A1000 Mobile’s specification.

Memory subsystems also diverge. The Arc A580 has 8 GB of GDDR6 memory on a 256-bit bus, with a bandwidth of 512.0 GB/s. The RTX A1000 Mobile has 4 GB of GDDR6 on a 128-bit bus, yielding 176.0 GB/s. That is a 2.9x difference in memory bandwidth, which heavily impacts fill-rate-bound workloads. The Arc A580’s pixel rate is 192.0 GPixel/s and its texture rate is 384.0 GTexel/s. The RTX A1000 Mobile’s pixel rate is 36.48 GPixel/s and texture rate is 72.96 GTexel/s. These are large gaps that show up in resolution-heavy rendering tasks.

Where Each One Wins

The Intel Arc A580 wins in every recorded benchmark category. Its higher shading unit count, larger memory bus, and significantly higher clock speeds make it the clear choice for compute-heavy tasks. The data shows an 88.2% lead in OpenCL and a 69.7% lead in Vulkan, which indicates that the Arc A580 is better suited for general-purpose GPU compute and rendering workloads that leverage Vulkan’s low-level API. Its 8 GB memory buffer and 512.0 GB/s bandwidth also give it a strong edge in applications that require large textures or high-resolution frame buffers.

The NVIDIA RTX A1000 Mobile, despite losing all head-to-head tests, has its own domain of applicability. Its 60 W TDP and IGP form factor make it suitable for thin-and-light laptops where power efficiency is paramount. The 64 tensor cores are a notable feature for AI inference tasks, although the recorded benchmarks do not include such tests. The RTX A1000 Mobile also has a lower transistor density and smaller die, which could translate to lower manufacturing costs, but the database does not provide price information.

In terms of raw performance, the Arc A580 is the unambiguous winner. Its average benchmark score of 57,756 places it above the RTX A1000 Mobile’s 47,743, and its nearest rivals are all within 1.1% of its score, indicating a competitive position in the desktop GPU market. The RTX A1000 Mobile’s nearest rivals are similarly close, with deltas ranging from -1.5% to +2.5%, but that cluster sits at a lower absolute performance level.

For users who need maximum compute throughput, the Arc A580 is the better choice. For portable systems that prioritize low power draw and integrated design, the RTX A1000 Mobile serves a different purpose. The benchmark data does not favor the NVIDIA part in any shared test, but its feature set, including tensor cores and a compact footprint, makes it a relevant option for specific mobile workloads. The Arc A580, with its dual-slot design and 175 W TDP, is not suitable for such environments, reinforcing the idea that these GPUs target different market segments despite the performance gap.
