Intel Arc A580 vs NVIDIA H20 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparisons between the Intel Arc A580 and the NVIDIA H20. The database lists three benchmark results for the Intel Arc A580: a 3DMark Steel Nomad DX12 score of 2229, a Geekbench OpenCL score of 91657, and a Geekbench Vulkan score of 79381. The NVIDIA H20 has no benchmark entries in the database, and its average benchmark score is recorded as 0. Consequently, a direct score-by-score comparison is not possible from the available measurements.

The Intel Arc A580's average benchmark score of 57756 places it in the 87th percentile among all GPUs in the database. Its nearest rivals include the AMD Radeon RX 5600 OEM with an average score of 58085 (0.6% higher), the Intel Arc A570M with 58239 (0.8% higher), the AMD Radeon RX 6950 XT with 58392 (1.1% higher), and the AMD Radeon RX 9070 GRE with 57367 (0.7% lower). The Arc A580 sits within a narrow band of roughly 1% of these competing parts, indicating that its average benchmark result is closely clustered with mid-range and previous-generation high-end offerings.

The NVIDIA H20, by contrast, has no recorded benchmark scores and no nearest rivals in the database. Its percentile rank of 50 reflects the absence of performance data rather than a measured midpoint. The database cannot establish a comparative performance delta between the two cards because the H20's score fields are empty.

Architecture Differences

The two accelerators diverge sharply in their underlying designs. The Intel Arc A580 uses the DG2-512 chip based on the Xe-HPG architecture, belonging to the Alchemist generation (Arc 5). It is manufactured on a 6 nm process at TSMC, with 21,700 million transistors on a 406 mm² die, yielding a transistor density of 53.4 million per square millimeter. The NVIDIA H20 uses the GH100 chip based on the Hopper architecture, from the Server Hopper (Hxx) generation. It is manufactured on a 5 nm process, also at TSMC, with 80,000 million transistors on an 814 mm² die, producing a transistor density of 98.3 million per square millimeter.

Memory configurations differ substantially. The Arc A580 carries 8 GB of GDDR6 memory on a 256-bit bus, with a memory clock of 2000 MHz (16 Gbps effective) and a bandwidth of 512.0 GB/s. The H20 carries 96 GB of HBM3 memory on a 6144-bit bus, with a memory clock of 1313 MHz (5.3 Gbps effective) and a bandwidth of 4.03 TB/s. The H20's memory capacity is 12 times larger, and its bandwidth is roughly 7.9 times higher.

Compute resources also diverge. The Arc A580 has 3072 shading units, 192 texture mapping units, 96 render output units, and 24 ray tracing cores; it has no tensor cores listed. The H20 has 9984 shading units, 312 texture mapping units, 24 render output units, and 312 tensor cores, with no ray tracing core count listed. The H20's shading unit count is more than triple that of the Arc A580. Texture rate for the H20 is 617.8 GTexel/s versus 384.0 GTexel/s for the Arc A580. Pixel rate favors the Arc A580 at 192.0 GPixel/s versus 47.52 GPixel/s for the H20, a consequence of the H20's low render output unit count. Floating point throughput shows the H20 at 39.54 TFLOPS FP32 and 79.07 TFLOPS FP16 (2:1), while the Arc A580 delivers 12.29 TFLOPS FP32 and 24.58 TFLOPS FP16 (2:1).

Clock behavior is similar at boost: the Arc A580 runs at 1700 MHz base and 2000 MHz boost, while the H20 runs at 1830 MHz base and 1980 MHz boost. The H20 draws significantly more power with a 500 W TDP and a suggested 900 W power supply, compared to the Arc A580's 175 W TDP and 450 W suggested power supply. The Arc A580 is a dual-slot card with two 8-pin power connectors, while the H20 is an SXM module with no listed power connectors or display outputs. The Arc A580 uses a PCIe 4.0 x16 interface and offers 1x HDMI 2.1 and 3x DisplayPort 2.0 outputs. The H20 uses PCIe 5.0 x16 and has no display outputs. API support also differs: the Arc A580 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the H20 lists N/A for DirectX, OpenGL, and Vulkan, reflecting its server-oriented role.

The Arc A580 was released on 2023-10-09 and lists the Xe Graphics as its predecessor and Battlemage as its successor. The H20 was released on 2024-01-31 with Server Ada as its predecessor and Server Blackwell as its successor. Both parts are currently listed as Active in production status.

The Verdict

The data indicates that these two products target completely different segments. The Intel Arc A580 has measurable benchmark results and an 87th percentile ranking, with an average score of 57756. The NVIDIA H20 has no benchmark scores and sits at the 50th percentile solely because of missing data. Any direct performance verdict is impossible from the recorded measurements.

For a desktop graphics workload, the Arc A580 is the only one of the two with supporting benchmark evidence. Its scores, including 2229 in 3DMark Steel Nomad DX12 and 91657 in Geekbench OpenCL, place it in the upper tier of the database. The H20, with no display outputs and no DirectX, OpenGL, or Vulkan support, cannot be assessed for such workloads from this data.

For compute-oriented applications, the H20's architecture suggests a different role: 96 GB of HBM3 memory, 4.03 TB/s bandwidth, 312 tensor cores, and 39.54 TFLOPS FP32. The Arc A580 offers 8 GB GDDR6, 512.0 GB/s bandwidth, no tensor cores, and 12.29 TFLOPS FP32. The H20's memory capacity and bandwidth are decisive advantages for large data sets, but the database contains no benchmark scores to confirm real-world performance.

Where Each One Wins

The Intel Arc A580 wins in any scenario that requires a display output. It provides 1x HDMI 2.1 and 3x DisplayPort 2.0, while the H20 has no display outputs at all. The Arc A580 also wins on pixel throughput with 192.0 GPixel/s against the H20's 47.52 GPixel/s, which matters for rasterization-heavy tasks. Its lower TDP of 175 W and suggested 450 W power supply make it far less demanding on system power infrastructure than the H20's 500 W TDP and 900 W suggested power supply. The Arc A580 also holds the advantage in software API compatibility, supporting DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, all of which are listed as N/A for the H20.

The NVIDIA H20 wins on memory capacity and bandwidth. Its 96 GB of HBM3 memory dwarfs the Arc A580's 8 GB of GDDR6, and its 4.03 TB/s bandwidth is roughly eight times higher. The H20 also has more than triple the shading units (9984 versus 3072) and higher texture rate (617.8 GTexel/s versus 384.0 GTexel/s). Its FP32 throughput of 39.54 TFLOPS is more than three times the Arc A580's 12.29 TFLOPS, and its FP16 throughput of 79.07 TFLOPS is similarly higher. The H20 includes 312 tensor cores, a feature entirely absent from the Arc A580's specifications. The H20 uses a PCIe 5.0 x16 interface versus the Arc A580's PCIe 4.0 x16, offering double the bus bandwidth potential.

The Arc A580 is the only one of the two with a recorded 3DMark Steel Nomad DX12 score (2229) and Geekbench scores (91657 OpenCL, 79381 Vulkan). The H20 has no recorded benchmark results, so the Arc A580 is the only part with measurable graphics performance in the database. The H20's role appears to be server-side compute, given its SXM module form factor, absence of display outputs, and lack of consumer graphics API support. The Arc A580's role is client-side rendering, with its dual-slot design, multiple display outputs, and full consumer API coverage.
