Intel Arc 130T Mobile vs Intel Arc A380E x2 Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results for the Intel Arc 130T Mobile against the Intel Arc A380E x2. Both products hold a 50th percentile ranking across all GPUs in the database, and neither has an average benchmark score recorded. The absence of synthetic test data means the comparison rests on architectural specifications and theoretical throughput metrics.

The Intel Arc A380E x2 delivers higher raw compute figures. Its FP32 throughput reaches 4.096 TFLOPS, which is 3.9% ahead of the Arc 130T Mobile's 3.942 TFLOPS. The FP16 results follow the same pattern, with the A380E x2 posting 8.192 TFLOPS versus 7.885 TFLOPS for the mobile part, again a 3.9% advantage. Pixel fill rates favor the A380E x2 at 64.00 GPixel/s against 61.60 GPixel/s, a 3.9% lead. Texture fill rates show the A380E x2 at 128.0 GTexel/s versus 123.2 GTexel/s, a 3.9% margin.

These differences are modest in percentage terms, but they are consistent across every measured throughput metric. The A380E x2 holds a small but uniform advantage in raw processing capability.

Architecture Differences

The two GPUs come from different Intel graphics lineages. The Arc 130T Mobile uses the Arrow Lake-H chip built on the Xe-LPG+ architecture, part of the Arc Graphics-M (Arrow Lake) generation. The A380E x2 uses the DG2-128 chip on the Xe-HPG architecture, belonging to the Alchemist (Arc 3) generation. Manufacturing processes differ as well: the mobile part uses TSMC's 5 nm node, while the A380E x2 uses TSMC's 6 nm node.

The A380E x2 reveals more of its physical details in the database. It carries 7,200 million transistors on a 157 mm² die, giving a transistor density of 45.9M per mm². The Arc 130T Mobile lists transistor count and die size as unknown. The A380E x2's predecessor is Xe Graphics, and its successor is Battlemage. The Arc 130T Mobile's predecessor is HD Graphics-M, with no successor listed.

The memory subsystems are fundamentally different. The Arc 130T Mobile uses system shared memory, with bandwidth described as system dependent. The A380E x2 has 6 GB of dedicated GDDR6 memory on a 96-bit bus, delivering 186.0 GB/s of bandwidth. Clock behavior differs substantially: the mobile GPU runs a 300 MHz base clock with a 2200 MHz boost, while the A380E x2 runs a fixed 2000 MHz for both base and boost, with memory clocked at 1937 MHz or 15.5 Gbps effective.

Compute unit counts favor the A380E x2. It has 1024 shading units, 64 texture mapping units, 32 raster operation units, and 8 ray tracing cores. The Arc 130T Mobile has 896 shading units, 56 TMUs, 28 ROPs, and 7 ray tracing cores. The A380E x2 leads by 14.3% in shading units, TMUs, and ROPs, and by 14.3% in ray tracing cores as well.

API support is identical: both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Power and physical design diverge sharply. The Arc 130T Mobile is an integrated graphics processor with a 35 W TDP and an IGP bus interface, designed for portable devices. The A380E x2 is a discrete single-slot card with a 130 W TDP, a PCIe 4.0 x8 interface, one 6-pin power connector, and a suggested 300 W power supply. Its dimensions are 265 mm in length, 127 mm in height, and 20 mm in width. The mobile part has no listed dimensions, power connectors, or suggested PSU, and its display outputs are described as portable device dependent. The A380E x2 provides 8x mini-DisplayPort 2.0 outputs.

Production status also differs. The Arc 130T Mobile is listed as active, released on January 12, 2025. The A380E x2 is end-of-life, released on March 31, 2024.

Where Each One Wins

The Intel Arc A380E x2 wins in every raw throughput category recorded in the database. Its higher shading unit count, larger memory bandwidth, and dedicated VRAM make it the stronger choice for compute-heavy workloads that rely on sustained fill rates and memory access. The 186.0 GB/s dedicated bandwidth versus system dependent memory gives it a clear structural advantage in scenarios where data movement dominates.

The Arc 130T Mobile wins in power efficiency and integration. Its 35 W TDP is a fraction of the A380E x2's 130 W, and its IGP form factor requires no additional power connectors or expansion slot. For portable devices where thermal and power envelopes are constrained, the mobile part is the only viable option between the two. Its 5 nm process node also suggests a more modern manufacturing approach compared to the 6 nm node of the A380E x2.

The A380E x2 has a production status advantage in availability. It is end-of-life with a successor already named, while the Arc 130T Mobile remains active in production. However, the mobile part's system shared memory means its real-world performance depends entirely on the host platform's memory configuration, which the database lists as system dependent. The A380E x2's fixed memory specifications remove that variable.
