Intel Arc A380E vs NVIDIA H100 PCIe 96 GB Comparison

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results between the Intel Arc A380E and the NVIDIA H100 PCIe 96 GB. The wins tally for both parts stands at zero, and no comparative scores or delta percentages exist for these two products. This absence of direct measurement data is itself informative: the two cards occupy entirely separate performance strata, and no workload in the database was run on both.

The Intel Arc A380E posts an average benchmark score of zero, placing it at the 50th percentile of all GPUs in the database. The NVIDIA H100 PCIe 96 GB also shows an average benchmark score of zero and a 50th percentile ranking. These figures indicate that neither card has accumulated a meaningful sample of benchmark runs in the database, so percentile positions reflect the lack of recorded data rather than actual performance equivalence.

Without direct scores, the raw specification deltas provide the only quantitative basis for comparison. The H100's FP32 throughput is listed at 62.08 TFLOPS, while the A380E delivers 4.096 TFLOPS, a 15.2x difference. In FP16 compute, the H100 reaches 248.3 TFLOPS with a 4:1 ratio, versus the A380E's 8.192 TFLOPS at 2:1, a 30.3x gap. Memory bandwidth separates even further: the H100's 3.36 TB/s exceeds the A380E's 186.0 GB/s by a factor of 18.1.

Architecture Differences

The two GPUs come from different architectural lineages. Intel's A380E uses the DG2-128 chip built on the Xe-HPG architecture, belonging to the Alchemist generation under the Arc 3 product tier. NVIDIA's H100 uses the GH100 chip on the Hopper architecture, part of the Server Hopper generation. Both are fabricated by TSMC, but on different nodes: the A380E uses a 6 nm process, while the H100 uses a 5 nm process.

Transistor counts reveal the scale disparity. The A380E integrates 7,200 million transistors on a 157 mm² die, yielding a density of 45.9 million transistors per square millimeter. The H100 packs 80,000 million transistors onto an 814 mm² die, achieving 98.3 million per square millimeter. The H100's die is 5.2x larger and holds 11.1x more transistors, with roughly double the packing density.

Shader and fixed-function hardware differ dramatically. The A380E has 1,024 shading units, 64 texture mapping units, and 32 raster output units, plus 8 ray tracing cores. The H100 has 16,896 shading units, 528 TMUs, and only 24 ROPs, with 528 tensor cores and no dedicated RT core count listed. The H100's pixel rate of 44.09 GPixel/s actually trails the A380E's 64.00 GPixel/s, despite the H100's far larger shader count, because the H100's ROP count is lower. Texture rate tells the opposite story: the H100's 969.9 GTexel/s vastly exceeds the A380E's 128.0 GTexel/s.

Memory subsystems could hardly be more different. The A380E uses 6 GB of GDDR6 on a 96-bit bus, with memory clocks at 1937 MHz (15.5 Gbps effective). The H100 uses 96 GB of HBM3 on a 5120-bit bus, with memory at 1313 MHz (5.3 Gbps effective). The H100's bus width is 53.3x wider, which more than compensates for its lower clock speed, producing 3.36 TB/s versus 186.0 GB/s.

Power and physical design diverge substantially. The A380E has a 75 W TDP, runs single-slot, requires no external power connectors, and suggests a 250 W PSU. The H100 has a 700 W TDP, occupies a dual-slot form factor, uses an 8-pin EPS connector, and recommends an 1100 W PSU. The A380E measures 254 mm long, 127 mm tall, and 20 mm thick. The H100 is 268 mm long and 111 mm tall, with no thickness recorded.

Interface and output capabilities also differ. The A380E uses PCIe 4.0 x8 and provides 4x DisplayPort 2.0 outputs. The H100 uses PCIe 5.0 x16 and has no display outputs at all. API support follows the split: the A380E lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the H100 lists no consumer graphics APIs.

The Verdict

The recorded data shows two products built for entirely different purposes. The Intel Arc A380E is a low-power, graphics-oriented card with display outputs, a compact single-slot design, and no external power requirement. The NVIDIA H100 PCIe 96 GB is a compute-oriented accelerator with massive memory capacity, tensor cores, and no display functionality.

For workloads that require FP32 or FP16 compute density, the H100 dominates by wide margins: 15.2x in FP32 and 30.3x in FP16. For workloads that depend on pixel throughput, the A380E actually leads with its 64.00 GPixel/s versus the H100's 44.09 GPixel/s. Memory-bound tasks favor the H100 overwhelmingly, given its 18.1x bandwidth advantage and 16x capacity advantage.

The A380E is the only one of the two with any graphics API support, listing DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The H100 has no recorded graphics API support and no display outputs. This makes the A380E the only viable choice for rendering to a screen. The H100 is the only choice for tensor-core workloads, with 528 tensor cores available versus none listed for the A380E.

Production status differs as well: the A380E is marked end-of-life, while the H100 remains active. Release dates show the A380E launched in March 2024, while the H100 arrived in March 2023. The A380E's predecessor is Xe Graphics and its successor is Battlemage; the H100's predecessor is Server Ada and its successor is Server Blackwell.

Where Each One Wins

The Intel Arc A380E wins in pixel throughput, posting 64.00 GPixel/s versus the H100's 44.09 GPixel/s. It also holds advantages in base and boost clocks, both at 2000 MHz compared to the H100's 1665 MHz base and 1837 MHz boost. The A380E is the only card with graphics API support and display outputs, making it the sole option for direct visual output. Its 75 W TDP and no-power-connector design allow installation in systems that cannot accommodate high-power accelerators. The A380E is smaller in length (254 mm vs 268 mm) and thicker (20 mm vs unrecorded), but its single-slot profile fits in denser chassis.

The NVIDIA H100 PCIe 96 GB wins in compute throughput, memory capacity, memory bandwidth, and texture processing. Its FP32 output of 62.08 TFLOPS is 15.2x higher, and its FP16 output of 248.3 TFLOPS is 30.3x higher. The H100's 96 GB memory capacity is 16x larger, and its 3.36 TB/s bandwidth is 18.1x higher. Texture rate favors the H100 at 969.9 GTexel/s, 7.6x the A380E's 128.0 GTexel/s. The H100's 528 tensor cores provide dedicated matrix math capability that the A380E lacks. The H100 also uses a wider PCIe interface at 5.0 x16 versus 4.0 x8, and its 5 nm node offers higher transistor density at 98.3M / mm² versus 45.9M / mm².

The transistor count difference underscores the performance separation: the H100 packs 80,000 million transistors, 11.1x the A380E's 7,200 million. The H100's die area of 814 mm² is 5.2x larger. These structural differences explain why the H100 commands a 700 W TDP while the A380E operates at 75 W. The data indicates that the A380E serves graphics-oriented, low-power environments, while the H100 serves compute-dense, high-bandwidth server workloads.
