Intel Arc A380E x2 vs NVIDIA H20 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between the Intel Arc A380E x2 and the NVIDIA H20. Both entries show an empty benchmark array, an average benchmark score of zero, and no nearest rivals listed. This absence of measured performance data means the comparison must rely entirely on architectural and specification differences drawn from the database.

The Intel Arc A380E x2 delivers 4.096 TFLOPS of FP32 compute, while the NVIDIA H20 delivers 39.54 TFLOPS. That is a difference of approximately 9.65 times in favor of the H20 in raw single-precision throughput. For FP16, the Arc A380E x2 reaches 8.192 TFLOPS with a 2:1 ratio, whereas the H20 reaches 79.07 TFLOPS with the same 2:1 ratio, a gap of roughly 9.65 times again.

Pixel throughput tells a different story. The Arc A380E x2 achieves 64.00 GPixel/s, which is 34.7% higher than the H20's 47.52 GPixel/s. Texture throughput favors the H20 decisively: 617.8 GTexel/s versus 128.0 GTexel/s, a 4.83 times advantage.

Memory bandwidth is another area of stark contrast. The H20 provides 4.03 TB/s of bandwidth through its 6144-bit HBM3 interface, while the Arc A380E x2 provides 186.0 GB/s through a 96-bit GDDR6 bus. The H20's bandwidth is approximately 21.7 times higher. Memory capacity follows the same pattern: 96 GB versus 6 GB, a 16 times difference.

The shading unit count shows the H20 with 9984 shading units against 1024 for the Arc A380E x2, a 9.75 times advantage. Texture mapping units number 312 versus 64, and ray tracing cores are listed as 8 for the Arc A380E x2 with no RT core count specified for the H20. Tensor cores are absent from the Arc A380E x2 entry but present at 312 on the H20.

Clock speeds are close at first glance. The Arc A380E x2 runs at 2000 MHz base and boost, while the H20 runs at 1830 MHz base and 1980 MHz boost. The memory clocks differ substantially: 1937 MHz (15.5 Gbps effective) for the Arc versus 1313 MHz (5.3 Gbps effective) for the H20. The effective data rate difference is 2.92 times in favor of the Arc, but the bus width difference of 64 times in favor of the H20 overwhelms that advantage in total bandwidth.

Where Each One Wins

The NVIDIA H20 wins in compute-heavy workloads. Its FP32 and FP16 figures are nearly an order of magnitude higher, and its tensor core count of 312 provides dedicated hardware for matrix operations that the Arc A380E x2 lacks entirely. The H20's 96 GB memory capacity and 4.03 TB/s bandwidth position it for large data sets, and its 617.8 GTexel/s texture rate indicates strong fill-rate performance for textured geometry.

The Intel Arc A380E x2 wins in pixel processing. Its 64.00 GPixel/s exceeds the H20's 47.52 GPixel/s, meaning the Arc can rasterize pixels faster at the output stage. The Arc also carries display outputs (8x mini-DisplayPort 2.0), while the H20 has no outputs at all, so the Arc is the only one of the two that can drive monitors directly.

The H20 operates in a different class of hardware. Its SXM module form factor, 500 W TDP, and suggested 900 W power supply indicate a server accelerator designed for dense compute racks. The Arc A380E x2 uses a single-slot design with a 130 W TDP and a suggested 300 W power supply, placing it in workstation or edge environments.

The database shows no wins recorded for either item (winsA is 0 and winsB is 0), which reinforces that the comparison is purely specification-driven rather than benchmark-driven. The percentile versus all GPUs is 50 for both, indicating median placement in the overall distribution, but with no benchmark scores behind those percentiles, they carry limited interpretive weight.

Architecture Differences

The Intel Arc A380E x2 uses the DG2-128 chip built on the Xe-HPG architecture, belonging to the Alchemist generation (Arc 3). The process node is 6 nm at TSMC, with 7,200 million transistors on a 157 mm² die, producing a transistor density of 45.9M per mm². The architecture includes 1024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. No tensor cores are listed.

The NVIDIA H20 uses the GH100 chip built on the Hopper architecture, belonging to the Server Hopper (Hxx) generation. The process node is 5 nm at TSMC, with 80,000 million transistors on an 814 mm² die, producing a transistor density of 98.3M per mm². The architecture includes 9984 shading units, 312 TMUs, 24 ROPs, and 312 tensor cores. No RT core count is listed.

The transistor count difference is 11.1 times in favor of the H20, while die size is 5.18 times larger. Transistor density is 2.14 times higher on the H20, reflecting the denser 5 nm process. The H20 also doubles the API support profile: it lists DirectX as N/A, OpenGL as N/A, and Vulkan as N/A, meaning it is not designed for graphics API workloads. The Arc A380E x2 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The production status differs as well. The Arc A380E x2 is end-of-life, with a predecessor of Xe Graphics and a successor of Battlemage. The H20 is active, with a predecessor of Server Ada and a successor of Server Blackwell. Release dates are close: the H20 released on 2024-01-31 and the Arc A380E x2 on 2024-03-31.

The Verdict

The data indicates two devices built for entirely different purposes. The NVIDIA H20 is a server accelerator with massive compute resources: 9984 shading units, 312 tensor cores, 96 GB of HBM3, and 4.03 TB/s of bandwidth. Its FP32 throughput of 39.54 TFLOPS and FP16 throughput of 79.07 TFLOPS place it far ahead of the Arc A380E x2 in raw number crunching. The H20 also carries no display outputs and no graphics API support, confirming its role as a compute-only part for datacenter deployments.

The Intel Arc A380E x2 is a graphics-oriented card. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, and it provides 8x mini-DisplayPort 2.0 outputs. Its pixel rate of 64.00 GPixel/s exceeds the H20's 47.52 GPixel/s, and its 130 W TDP with a single-slot form factor makes it suitable for compact systems. Its 6 GB memory capacity and 186.0 GB/s bandwidth are modest by comparison, but adequate for its intended graphics workload.

Users who need a server accelerator for compute tasks should select the NVIDIA H20 based on its 9.65 times higher FP32, 9.75 times more shading units, 312 tensor cores, and 16 times more memory. Users who need a display-capable graphics card with pixel throughput and graphics API support should select the Intel Arc A380E x2, as the H20 cannot output to a display at all. The H20's active production status and the Arc's end-of-life status in the database also inform a long-term procurement decision. The Arc A380E x2 has a successor named Battlemage, while the H20 has a successor named Server Blackwell, so both product lines continue forward in some form.
