Intel Arc A580 vs NVIDIA H20 NVL16 Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison: Intel Arc A580 has three benchmark entries, while NVIDIA H20 NVL16 has none. The database shows no head-to-head benchmark tests between these two devices, and the win count stands at zero for both. This absence of direct measurement data means any comparison must rely on the available specification fields and the single average benchmark score recorded for the Intel part.

The Intel Arc A580 posts an average benchmark score of 57,756 across its tested workloads. Its nearest rivals in the database include the AMD Radeon RX 5600 OEM at 58,085 (0.6% higher), the AMD Radeon RX 9070 GRE at 57,367 (0.7% lower), the Intel Arc A570M at 58,239 (0.8% higher), and the AMD Radeon RX 6950 XT at 58,392 (1.1% higher). These deltas place the A580 within roughly one percentage point of all four neighbors, indicating a tight cluster of performance around the 57,000 to 58,400 score band. The A580 sits at the 87th percentile among all GPUs in the database, which means it outperforms a substantial majority of recorded graphics cards.

The NVIDIA H20 NVL16 has no benchmark scores recorded. Its average benchmark score is listed as zero, and it has no nearest rivals. The percentile field places it at the 50th percentile among all GPUs, but with no actual test data this figure appears to represent a neutral default rather than a measured outcome. The database cannot confirm any performance level for this device through direct testing.

Where Each One Wins

The Intel Arc A580 wins in every category where measurement data exists. It has recorded results in 3dmark Steel Nomad DX12, Geekbench OpenCL, and Geekbench Vulkan. The 3dmark score of 2,229 reflects rasterization performance under DirectX 12. The Geekbench OpenCL score of 91,657 and the Vulkan score of 79,381 indicate strong compute throughput across two different API paths. The Vulkan result trails the OpenCL result by about 13%, which suggests the driver and hardware combination favors OpenCL workloads under the Geekbench test harness.

The NVIDIA H20 NVL16 cannot claim any benchmark wins because no scores exist for it. The data indicates this is a server-oriented product with no display outputs, no DirectX support, no OpenGL support, and no Vulkan support. Its API table lists all three graphics APIs as N/A, which aligns with its role as a compute-focused accelerator rather than a consumer graphics card. The absence of benchmark entries likely stems from the test suite being designed for graphics-capable devices, not from any judgment about compute capability.

For compute-oriented tasks, the specification sheet offers some indirect signals. The H20 NVL16 uses the GH100 chip on the Hopper architecture, built on a 5 nm process at TSMC. It integrates 80,000 million transistors on a 814 mm² die, yielding a transistor density of 98.3 million per square millimeter. The A580 uses the DG2-512 chip on Xe-HPG architecture, also fabricated by TSMC but on a 6 nm process. It contains 21,700 million transistors on a 406 mm² die, for a density of 53.4 million per square millimeter. These architectural figures point to the H20 NVL16 as a much larger and denser compute device, but without benchmark scores the database cannot translate that into measured performance.

The Verdict

The data supports only one clear choice for graphics-oriented buyers: the Intel Arc A580. It has verified benchmark scores, a 87th percentile ranking, and a position among four closely matched rivals. The NVIDIA H20 NVL16 has no recorded performance data, no graphics API support, and no display outputs. It cannot run the same tests, and the database treats its average score as zero.

For server compute scenarios, the H20 NVL16 presents a different profile. It offers 96 GB of HBM3 memory on a 6144-bit bus, delivering 4.03 TB/s of bandwidth. The A580 provides 8 GB of GDDR6 on a 256-bit bus, with 512.0 GB/s of bandwidth. The H20 NVL16 also lists 312 tensor cores, while the A580 lists none. The FP32 throughput for the H20 NVL16 is 39.54 TFLOPS, compared to 12.29 TFLOPS for the A580. FP16 figures show 79.07 TFLOPS for the H20 NVL16 versus 24.58 TFLOPS for the A580. These numbers indicate a wide gap in raw compute and memory capacity, but the absence of benchmarks keeps that gap unverified.

The A580 uses a dual-slot design with two 8-pin power connectors and a suggested PSU of 450 W. The H20 NVL16 is an SXM module with a suggested PSU of 800 W and no power connector listing. The H20 NVL16 consumes up to 400 W according to its TDP field, while the A580 lists 175 W. The H20 NVL16 supports PCIe 5.0 x16, while the A580 uses PCIe 4.0 x16. Buyers needing a graphics card with display outputs should choose the A580. Buyers needing a high-memory compute module should consider the H20 NVL16, but the database offers no measured evidence of its performance.
