Intel Arc A380E x2 vs NVIDIA GeForce RTX 4080 SUPER Comparison

The Verdict

The recorded data separates these two GPUs into entirely different performance classes. The NVIDIA GeForce RTX 4080 SUPER holds the 86th percentile among all GPUs in the database, with an average benchmark score of 54,209. The Intel Arc A380E x2 sits at the 50th percentile with an average benchmark score of 0, meaning no benchmark entries were recorded for it. The RTX 4080 SUPER delivers 52.22 TFLOPS of FP32 compute, 816.0 GTexel/s texture rate, and 285.6 GPixel/s pixel throughput. The Intel part offers 4.096 TFLOPS FP32, 128.0 GTexel/s, and 64.00 GPixel/s. The RTX 4080 SUPER is 12.75 times ahead in FP32 throughput, 6.4 times ahead in texture fill, and 4.5 times ahead in pixel fill. The RTX 4080 SUPER also carries a launch MSRP of 999 USD.

The Intel Arc A380E x2 is positioned for multi-display or compact deployments, with 8x mini-DisplayPort 2.0 outputs, a single-slot form factor, and 130 W TDP. The RTX 4080 SUPER targets high-end rendering workloads, featuring 80 RT cores, 320 tensor cores, and 16 GB of GDDR6X memory on a 256-bit bus. Users needing maximum compute, ray tracing, or memory bandwidth should select the RTX 4080 SUPER. Users constrained by slot width, power draw, or display output count should examine the Intel Arc A380E x2, though its compute capabilities remain far below the NVIDIA part.

Architecture Differences

The Intel Arc A380E x2 uses the DG2-128 chip built on TSMC's 6 nm process with the Xe-HPG architecture, belonging to the Alchemist (Arc 3) generation. The die contains 7,200 million transistors across 157 mm², yielding a transistor density of 45.9M per mm². The NVIDIA GeForce RTX 4080 SUPER uses the AD103 chip on TSMC's 5 nm process with the Ada Lovelace architecture from the GeForce 40 generation. Its die holds 45,900 million transistors across 379 mm², giving a density of 121.1M per mm². The density gap reflects the newer process node and the larger GPU complex.

The Intel GPU implements 1024 shading units, 64 TMUs, 32 ROPs, and 8 RT cores. It lacks dedicated tensor cores. The NVIDIA GPU scales up dramatically: 10,240 shading units, 320 TMUs, 112 ROPs, 80 RT cores, and 320 tensor cores. The tensor core count gives the RTX 4080 SUPER a 10x advantage in AI-accelerated workloads. The Intel part does support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, matching the API feature set of the RTX 4080 SUPER.

Memory architecture differs substantially. The Intel card uses 6 GB of GDDR6 on a 96-bit bus with 186.0 GB/s bandwidth. The NVIDIA card uses 16 GB of GDDR6X on a 256-bit bus with 736.3 GB/s bandwidth. The RTX 4080 SUPER offers 2.7 times the memory capacity and 3.96 times the bandwidth. The Intel part's memory clock runs at 1937 MHz (15.5 Gbps effective), while the NVIDIA part runs at 1438 MHz (23 Gbps effective). The higher effective data rate on the NVIDIA card compensates for its lower raw clock.

Power delivery and physical design also diverge. The Intel card uses a single 6-pin connector, a single-slot cooler, and a 130 W TDP with a 300 W suggested PSU. The NVIDIA card uses a single 16-pin connector, a triple-slot cooler, and a 320 W TDP with a 700 W suggested PSU. The Intel card measures 265 mm in length, 127 mm in height, and 20 mm in width. The NVIDIA card measures 310 mm in length, 140 mm in height, and 61 mm in width. The bus interface differs as well: PCIe 4.0 x8 for Intel versus PCIe 4.0 x16 for NVIDIA.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs, and the Intel Arc A380E x2 has no recorded benchmark scores. The comparison relies on the RTX 4080 SUPER's benchmark suite and the Intel card's theoretical specifications.

The RTX 4080 SUPER posts a 3DMark Steel Nomad DX12 score of 6,600. Its Geekbench OpenCL score reaches 219,065, and its Geekbench Vulkan score reaches 260,075. In PassMark tests, the RTX 4080 SUPER scores 34,245 in G3D, 19,822 in GPU compute, 1,270 in G2D, 381 in DirectX 9, 301 in DirectX 11, 193 in DirectX 10, and 134 in DirectX 12. The average benchmark score across all tests is 54,209.

Relative to its nearest rivals in the database, the RTX 4080 SUPER trails the NVIDIA GeForce RTX 4080 by 0.1 percent (54,247 average score), sits 1.1 percent behind the AMD Radeon Pro W5700X (54,828), and falls 2.7 percent behind the AMD Radeon RX 6750 GRE 12 GB (55,698) and 2.8 percent behind the AMD Radeon 8060S (55,757). The performance deltas are narrow, all within 3 percent, indicating the RTX 4080 SUPER sits in a tightly contested band of high-end GPUs.

The Intel Arc A380E x2 shows no benchmark entries, so its percentile of 50 reflects a mid-pack standing based on hardware characteristics. Its FP16 output of 8.192 TFLOPS using a 2:1 ratio versus the RTX 4080 SUPER's 52.22 TFLOPS at 1:1 shows the NVIDIA card also handles half-precision workloads far more efficiently. The RTX 4080 SUPER's FP16 throughput is 6.4 times higher, and it does not rely on a reduced-rate path for FP16.

Texture and pixel throughput follow the same pattern. The RTX 4080 SUPER renders 816.0 GTexel/s against the Intel card's 128.0 GTexel/s. Pixel output reaches 285.6 GPixel/s versus 64.00 GPixel/s. Memory bandwidth of 736.3 GB/s versus 186.0 GB/s reinforces the gap. The NVIDIA card also has 320 tensor cores, which the Intel part completely lacks, making the RTX 4080 SUPER the only option for hardware-accelerated AI inference or DLSS-style workloads.

The RTX 4080 SUPER's closest rival data shows it performs within 2.8 percent of four other GPUs. This places it at the upper edge of consumer-class performance. The Intel Arc A380E x2, by contrast, sits in a different product category entirely: its single-slot, 6-pin, 130 W design and 8 mini-DisplayPort outputs suggest a niche for multi-GPU array or display-wall configurations where raw throughput matters less than physical density and output count.
