Where Each One Wins

The benchmark data is one-sided. The RTX 5080 Mobile has ten recorded benchmark scores across DirectX 9, 10, 11, 12, OpenCL, Vulkan, 2D, 3D, and compute workloads. The Arc A380E x2 has zero recorded scores in the database.

This means every measurable workload category belongs to the NVIDIA part. In DirectX 12, the RTX 5080 Mobile scores 116 in PassMark DirectX 12, 253 in DirectX 11, 171 in DirectX 10, and 314 in DirectX 9. Its PassMark G3D score is 27711, and GPU compute reaches 12134. The 2D score is 1095. In Geekbench, it records 166986 for OpenCL and 169754 for Vulkan. In 3DMark Steel Nomad DX12, it scores 4952.

The Arc A380E x2 cannot claim a single benchmark win because no scores exist for it. Its only advantage is in form factor flexibility: it is a single-slot, 265 mm card with 8x mini-DisplayPort 2.0 outputs, while the RTX 5080 Mobile is an integrated GPU with portable-device-dependent outputs.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The Intel Arc A380E x2 is built on the Xe-HPG architecture, specifically the Alchemist (Arc 3) generation, using the DG2-128 chip. The RTX 5080 Mobile uses the Blackwell 2.0 architecture in the GeForce 50-series, built around the GB203 chip.

The manufacturing process differs: Intel uses a 6 nm node at TSMC, while NVIDIA uses a 5 nm node at TSMC. The transistor counts are dramatically different. Intel packs 7,200 million transistors into a 157 mm² die, giving a transistor density of 45.9M per mm². NVIDIA packs 45,600 million transistors into a 378 mm² die, for a density of 120.6M per mm².

The RTX 5080 Mobile has a much larger memory subsystem: 16 GB of GDDR7 on a 256-bit bus versus 6 GB of GDDR6 on a 96-bit bus. It also has a wider PCIe implementation, using PCIe 5.0 x16 rather than PCIe 4.0 x8.

Feature-wise, the RTX 5080 Mobile integrates 240 tensor cores for AI workloads, while the Arc A380E x2 has no tensor core count listed. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The clock behavior is also distinct. Intel runs at a flat 2000 MHz base and boost. NVIDIA runs at 975 MHz base and 1500 MHz boost, with the memory clocked at 1750 MHz (28 Gbps effective) versus Intel's 1937 MHz (15.5 Gbps effective).

Specification Differences

The core configuration is the largest gap. The RTX 5080 Mobile uses 7680 shading units, 240 TMUs, 96 ROPs, 60 RT cores, and 240 tensor cores. The Arc A380E x2 uses 1024 shading units, 64 TMUs, 32 ROPs, and 8 RT cores.

Rasterization throughput reflects this. NVIDIA reaches 144.0 GPixel/s pixel rate and 360.0 GTexel/s texture rate. Intel reaches 64.00 GPixel/s and 128.0 GTexel/s.

Power delivery is inverted from the performance gap. The Arc A380E x2 draws 130 W and needs a 300 W suggested PSU plus a 6-pin connector. The RTX 5080 Mobile draws 80 W with no power connectors, as it is an IGP.

The physical format differs completely. The Intel card is 265 mm long, 127 mm tall, and 20 mm wide, taking a single slot. The RTX 5080 Mobile has no listed dimensions, as it is designed for portable devices.

Display outputs also differ. Intel provides 8x mini-DisplayPort 2.0. NVIDIA lists "Portable Device Dependent," meaning the outputs vary by laptop implementation.

Memory clocks are 1937 MHz (15.5 Gbps effective) for Intel and 1750 MHz (28 Gbps effective) for NVIDIA. The effective data rate is nearly double on the NVIDIA part.

Head-to-Head Benchmarks

There are no direct head-to-head benchmark entries in the database, so the comparison relies on the RTX 5080 Mobile's recorded scores versus the Arc A380E x2's absence of any scores.

The RTX 5080 Mobile's average benchmark score is 38349. Its nearest rivals in the database are the NVIDIA GeForce MX570 at 38299 (0.1% faster), the NVIDIA GeForce RTX 4080 Mobile at 38135 (0.6% slower), the NVIDIA GeForce MX570 A at 38691 (0.9% faster), and the AMD Radeon Pro 580X at 38706 (0.9% faster). This places the RTX 5080 Mobile in a tight cluster with those parts, all within roughly 1% of each other.

Within its own benchmark set, the RTX 5080 Mobile shows its strongest results in Geekbench Vulkan at 169754 and OpenCL at 166986. The PassMark G3D score of 27711 and GPU compute of 12134 are also substantial. The API-specific PassMark scores are lower in absolute terms, but they are the only recorded data points for those workloads.

The Arc A380E x2 has an average benchmark score of 0 and no nearest rivals listed. This means the database contains no measured performance data for it. Any comparison of raw scores is impossible, and the only verifiable difference in this category is that the RTX 5080 Mobile has measurable results while the Intel part does not.

The Verdict

The data supports only one conclusion for performance: the RTX 5080 Mobile is the only part with recorded benchmark results. Its 38349 average score, 81st percentile ranking, and ten separate workload scores demonstrate a fully characterized GPU. The Arc A380E x2 has no scores in any category, so it cannot be positioned as competitive on measured performance.

For users who need a discrete, single-slot card with multiple display outputs, the Arc A380E x2 has a clear physical advantage: 8x mini-DisplayPort 2.0, a 265 mm length, and a 130 W TDP with a 6-pin connector. This makes it suitable for multi-display setups or systems requiring a specific card footprint.

For users who prioritize compute, memory bandwidth, and modern features, the RTX 5080 Mobile is the stronger choice based on its specifications alone. It offers 16 GB of GDDR7, 896.0 GB/s bandwidth, 7680 shading units, 60 RT cores, and 240 tensor cores, all within an 80 W envelope. Its 23.04 TFLOPS FP32 throughput is over five times the Intel part's 4.096 TFLOPS.

The production status also matters. The Arc A380E x2 is end-of-life with no successor listed in the database, while the RTX 5080 Mobile is active. The Intel part's predecessor is Xe Graphics and its successor is Battlemage, but no further details are recorded.

The RTX 5080 Mobile's nearest rivals all sit within 1% of its average score, indicating that it performs in line with other high-end mobile GPUs from the previous generation. The Arc A380E x2 has no comparable data points, which limits any quantitative verdict.

In practical terms, the RTX 5080 Mobile is the only one of these two with measurable performance, and it substantially outperforms the Intel part on every specification that affects gaming and compute workloads. The Arc A380E x2 remains a viable option only where its specific physical format and multi-DisplayPort output configuration are required, not where raw performance is the deciding factor.
