Intel Arc A380E x2 vs NVIDIA Rubin GPU Comparison

Head-to-Head Benchmarks

The recorded data for the Intel Arc A380E x2 and the NVIDIA Rubin GPU does not include any direct head-to-head benchmark scores. Both products have an empty benchmark array, and their average benchmark score is listed as 0. The wins column shows 0 for each side, indicating that no comparative measurements exist in the database. What can be analyzed instead is the raw computational throughput derived from their respective specifications, and how those figures position each product relative to the broader GPU landscape.

The most striking contrast appears in raw floating-point performance. The NVIDIA Rubin GPU delivers 130.0 TFLOPS of FP32 compute, while the Intel Arc A380E x2 produces 4.096 TFLOPS. That places the Rubin GPU at roughly 31.7 times the FP32 throughput of the Intel part, based on the figures recorded. For FP16 workloads, the Rubin GPU outputs 260.0 TFLOPS with a 2:1 ratio, whereas the Intel Arc A380E x2 reaches 8.192 TFLOPS, also at a 2:1 ratio. The delta here is even larger in absolute terms, with NVIDIA's part exceeding Intel's by approximately 251.8 TFLOPS.

Texture throughput tells a similar story. The Rubin GPU achieves a texture rate of 2,031.2 GTexel/s, compared to 128.0 GTexel/s for the Intel Arc A380E x2. That is a factor of roughly 15.9 in favor of the NVIDIA part. Pixel rates, however, are surprisingly close. The Intel Arc A380E x2 posts 64.00 GPixel/s, while the NVIDIA Rubin GPU records 54.41 GPixel/s. This means the Intel part holds a narrow advantage in pixel throughput, despite its far smaller overall compute footprint. The reason appears to be the ROP configuration: Intel uses 32 ROPs on a 96-bit memory bus, while NVIDIA uses only 24 ROPs on a 16,384-bit bus.

Memory bandwidth is another area with a massive gap. The Rubin GPU lists 22.1 TB/s of bandwidth from 288 GB of HBM4 memory across a 16,384-bit bus. The Intel Arc A380E x2 lists 186.0 GB/s from 6 GB of GDDR6 on a 96-bit bus. The NVIDIA part offers roughly 118.8 times the bandwidth. Effective memory clock also differs: 10.8 Gbps for the Rubin GPU versus 15.5 Gbps for the Intel part, though the Intel part's higher per-pin speed does not compensate for the enormous bus-width difference.

Neither product has recorded benchmark scores, so percentile rankings remain at 50 for both, which is the neutral midpoint in the database. Without actual test data, the specifications themselves serve as the only measurable differentiator.

Where Each One Wins

The Intel Arc A380E x2 wins in the narrow category of pixel fill rate. Its 64.00 GPixel/s exceeds the Rubin GPU's 54.41 GPixel/s, a difference of about 9.6 GPixel/s. This suggests that for workloads heavily dependent on rasterization throughput at lower resolutions, the Intel part could have an edge, though no benchmark data confirms this in practice.

The Intel part also wins on physical integration details. It is a single-slot card with a 265 mm length, 127 mm height, and 20 mm width. It uses a single 6-pin power connector and requires a suggested PSU of 300 W. It includes 8x mini-DisplayPort 2.0 outputs, making it suitable for multi-display configurations. The Rubin GPU, by contrast, is an SXM module with no display outputs at all. It lists no dimensions, no power connectors, and a suggested PSU of 2700 W.

The NVIDIA Rubin GPU wins in every compute-heavy category. Its 130.0 TFLOPS FP32 and 260.0 TFLOPS FP16 figures dwarf the Intel part. Its 896 texture mapping units and 896 tensor cores provide a hardware foundation for AI and deep learning workloads that the Intel Arc A380E x2 lacks entirely, as the Intel part records no tensor cores. The Rubin GPU's 22.1 TB/s memory bandwidth and 288 GB capacity make it suitable for large model inference and training, while the Intel part's 186.0 GB/s and 6 GB capacity limit it to far smaller working sets.

The Rubin GPU also wins on process technology and transistor density. It uses a 3 nm process with 336,000 million transistors on a 1456 mm² die, yielding a density of 230.8M transistors per mm². The Intel part uses a 6 nm process with 7,200 million transistors on a 157 mm² die, for a density of 45.9M per mm².

Architecture Differences

The Intel Arc A380E x2 is built on the Xe-HPG architecture, specifically the DG2-128 chip, and belongs to the Alchemist (Arc 3) generation. The NVIDIA Rubin GPU uses the Rubin architecture, built around the GR100 chip, and belongs to the Server Rubin (Rxx) generation. These are fundamentally different design philosophies: Intel's part is a compact, power-limited graphics card, while NVIDIA's part is a server-grade compute module.

The manufacturing process differs significantly. Intel uses a 6 nm process from TSMC. NVIDIA also uses TSMC, but at 3 nm. Transistor counts reflect this: 7,200 million for Intel versus 336,000 million for NVIDIA. Die size also differs, with Intel at 157 mm² and NVIDIA at 1456 mm². The transistor density numbers, 45.9M per mm² versus 230.8M per mm², show that NVIDIA's design packs far more logic into each square millimeter.

Core configurations vary widely. The Intel part has 1,024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. It has no tensor cores listed. The NVIDIA part has 28,672 shading units, 896 TMUs, 24 ROPs, and 896 tensor cores. Its ray tracing core count is not listed. The shading unit ratio is 28:1 in NVIDIA's favor, while the TMU ratio is 14:1.

Memory architecture is another major divergence. Intel uses 6 GB of GDDR6 on a 96-bit bus. NVIDIA uses 288 GB of HBM4 on a 16,384-bit bus. The memory clock differs as well: 1937 MHz with 15.5 Gbps effective for Intel, versus 2695 MHz with 10.8 Gbps effective for NVIDIA. The bus width difference of 16,288 bits is the primary driver of the bandwidth gap.

API support also separates the two. The Intel Arc A380E x2 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA Rubin GPU lists N/A for DirectX, OpenGL, and Vulkan, consistent with its server-oriented role and lack of display outputs.
