Intel Arc A580 vs NVIDIA Rubin GPU Comparison

Head-to-Head Benchmarks

The recorded data for these two parts cannot be compared through shared benchmark runs. The Intel Arc A580 has three benchmark results in the database, while the NVIDIA Rubin GPU has no recorded benchmark scores. The A580 produces a 3DMark Steel Nomad DX12 score of 2229, a Geekbench OpenCL score of 91657, and a Geekbench Vulkan score of 79381. The Rubin GPU's average benchmark score is 0, and its percentile versus all GPUs sits at 50, which reflects a part with no measured performance entries rather than a competitive result.

The Arc A580's average benchmark score is 57756. That places it in the 87th percentile of all GPUs in the database. Its nearest rivals show how tightly grouped this part is at its performance level. The AMD Radeon RX 5600 OEM averages 58085, which is 0.6% higher than the A580. The Intel Arc A570M averages 58239, 0.8% higher. The AMD Radeon RX 6950 XT averages 58392, 1.1% higher. The AMD Radeon RX 9070 GRE averages 57367, which is 0.7% lower than the A580. The spread from the lowest rival to the highest is only about 1.8 percentage points, so the A580 sits in a narrow performance band where no single rival dominates it by a meaningful margin.

The Rubin GPU has no nearest rivals and no benchmark entries. Any direct head-to-head comparison in this database is therefore limited to specifications and architectural characteristics, not measured performance. The data shows no wins for either part in head-to-head benchmarks because no shared tests exist.

Where Each One Wins

The Arc A580 wins in the only category where actual measurements exist: client-side rendering workloads. Its 3DMark Steel Nomad DX12 result of 2229 demonstrates functional DirectX 12 Ultimate support, and its Geekbench Vulkan score of 79381 confirms that it can execute modern cross-platform graphics APIs. Its Geekbench OpenCL score of 91657 shows compute capability that is competitive with the GPUs around it in the database, as its nearest rivals all fall within roughly one percentage point of its average score.

The Rubin GPU wins in raw specification capacity. Its FP32 throughput is 130.0 TFLOPS, which is more than ten times the A580's 12.29 TFLOPS. Its memory bandwidth is 22.1 TB/s, which dwarfs the A580's 512.0 GB/s. The Rubin GPU has 28672 shading units against the A580's 3072. It also has 896 tensor cores, while the A580 has none recorded. None of these advantages appear in benchmark scores because no benchmarks are recorded for the Rubin GPU, but the specification data indicates a part built for a very different workload class.

The use-case split is clear. The Arc A580 is a client graphics card with PCIe 4.0 x16, display outputs, and a dual-slot cooler. The Rubin GPU is a server accelerator with no display outputs, an SXM module form factor, PCIe 6.0 x16, and a 2300 W TDP. One targets rasterization and compute on a desktop; the other targets server-scale acceleration where graphics output is irrelevant.

Architecture Differences

The two parts come from different manufacturers, different architectures, and different process nodes. The Arc A580 uses Intel's Xe-HPG architecture on the DG2-512 chip, belonging to the Alchemist (Arc 5) generation. It is built on TSMC's 6 nm node with 21,700 million transistors on a 406 mm² die, giving a transistor density of 53.4 million per square millimeter. The Rubin GPU uses NVIDIA's Rubin architecture on the GR100 chip, belonging to the Server Rubin (Rxx) generation. It is built on TSMC's 3 nm node with 336,000 million transistors on a 1456 mm² die, giving a transistor density of 230.8 million per square millimeter. The Rubin GPU has roughly 15.5 times the transistor count and a density more than four times higher.

Memory architecture differs fundamentally. The Arc A580 uses 8 GB of GDDR6 on a 256-bit bus with 512.0 GB/s bandwidth. The Rubin GPU uses 288 GB of HBM4 on a 16384-bit bus with 22.1 TB/s bandwidth. The Rubin GPU has 64 times the memory capacity and roughly 43 times the bandwidth.

Compute resources diverge sharply. The Arc A580 has 3072 shading units, 192 texture mapping units, 96 raster output units, and 24 ray tracing cores. It has no tensor cores recorded. The Rubin GPU has 28672 shading units, 896 texture mapping units, 24 raster output units, and 896 tensor cores. Its ray tracing core count is not recorded. The A580 has a higher pixel rate at 192.0 GPixel/s versus 54.41 GPixel/s, which reflects its client-oriented design. The Rubin GPU has a much higher texture rate at 2,031.2 GTexel/s versus 384.0 GTexel/s.

Clock behavior also differs. The Arc A580 runs at a 1700 MHz base and 2000 MHz boost, with memory at 2000 MHz or 16 Gbps effective. The Rubin GPU runs at a 700 MHz base and 2267 MHz boost, with memory at 2695 MHz or 10.8 Gbps effective. The lower base clock on the Rubin GPU is typical of a large server chip that relies on boost behavior under load.

API support separates the two entirely. The Arc A580 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Rubin GPU has N/A for DirectX, OpenGL, and Vulkan, which reflects its server positioning where traditional graphics APIs are not the target interface.

Power and physical configuration differ by a wide margin. The Arc A580 has a 175 W TDP, uses two 8-pin power connectors, and requires a 450 W suggested PSU. The Rubin GPU has a 2300 W TDP, uses an SXM module slot, and requires a 2700 W suggested PSU. The Arc A580 is dual-slot with 1x HDMI 2.1 and 3x DisplayPort 2.0 outputs. The Rubin GPU has no outputs.

The Verdict

The data describes two products with almost no overlap in purpose. The Intel Arc A580 is a measured, working client GPU. It has benchmark scores in the database, sits in the 87th percentile of all GPUs, and competes within a tight band around the AMD Radeon RX 5600 OEM, AMD Radeon RX 9070 GRE, Intel Arc A570M, and AMD Radeon RX 6950 XT. Its nearest rival, the RX 5600 OEM, is only 0.6% ahead, and the RX 9070 GRE is only 0.7% behind. The A580 delivers DX12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support, and its 192.0 GPixel/s pixel rate shows a design aimed at rasterization output.

The NVIDIA Rubin GPU is a server accelerator with no recorded benchmarks and no client graphics features. Its 130.0 TFLOPS FP32 throughput, 288 GB HBM4 memory, and 22.1 TB/s bandwidth place it in a completely different class, but the database contains no measurements to confirm how that specification translates into real workload performance. Its N/A API support and lack of display outputs make it unsuitable for the same systems that would use the Arc A580.

A buyer choosing between these two would be choosing between a desktop graphics card with verified performance and a server compute module with no measured results in the database. The Arc A580 is the only one of the two with any benchmark evidence to evaluate. The Rubin GPU's specifications are enormous, but without benchmark data, its actual performance cannot be assessed from the database. The choice depends on whether the system needs a functional graphics output and measured client performance, or a server accelerator whose capabilities are documented only through specifications.
