Intel Arc A380E vs Intel Arc Graphics 2 Xe Mobile Comparison

Intel Arc A380E and Intel Arc Graphics 2 Xe Mobile are two distinctly positioned graphics solutions from Intel, separated by architecture, process technology, and intended use case. The A380E is a discrete, single-slot desktop card built on the Xe-HPG architecture, while the 2 Xe Mobile is an integrated graphics processor (IGP) designed for portable devices, based on the newer Xe3-LPG architecture. The data shows a clear performance hierarchy, but the mobile part compensates with significantly lower power consumption and a much smaller physical footprint.

Head-to-Head Benchmarks

The database lists no direct head-to-head benchmark scores for these two parts, as the A380E and the 2 Xe Mobile occupy different market segments. However, the recorded specifications allow for a direct comparison of theoretical peak performance metrics, which are the primary indicators available for these unbenchmarked units.

The most significant gap appears in raw compute throughput. The A380E delivers 4.096 TFLOPS of FP32 performance, while the 2 Xe Mobile provides 1,280.0 GFLOPS, which converts to 1.28 TFLOPS. This means the A380E offers roughly 3.2 times the single-precision compute throughput of the mobile part. A similar ratio exists in texture processing: the A380E achieves a texture rate of 128.0 GTexel/s compared to 40.00 GTexel/s for the 2 Xe Mobile, a 3.2x advantage. Pixel fill rate shows a wider disparity, with the A380E hitting 64.00 GPixel/s versus the mobile part's 20.00 GPixel/s, a 3.2x lead as well.

Clock speeds tell another part of the story. The A380E runs at a fixed 2000 MHz for both base and boost, whereas the 2 Xe Mobile has a base clock of just 300 MHz but a boost clock of 2500 MHz. The mobile chip's low base clock reflects power-saving idle states, while its 2500 MHz boost is 25% higher than the A380E's maximum. However, the mobile part's much smaller execution engine (256 shading units versus 1024) means that even with a higher boost clock, it cannot match the discrete card's throughput.

Memory bandwidth is another decisive factor. The A380E uses 6 GB of dedicated GDDR6 memory on a 96-bit bus, yielding 186.0 GB/s of bandwidth. The 2 Xe Mobile relies on System Shared memory, with bandwidth described as "System Dependent" in the database. In practice, shared memory bandwidth is typically far lower than dedicated GDDR6, and it is also shared with the CPU, so the A380E's memory subsystem is categorically faster and more predictable for graphics workloads.

Where Each One Wins

The Intel Arc A380E wins decisively in every measured performance category. Its 3.2x advantage in FP32 compute, texture fill rate, and pixel fill rate makes it the stronger choice for any workload that relies on sustained, high-throughput graphics processing. The dedicated 6 GB GDDR6 frame buffer with 186.0 GB/s bandwidth ensures that data-heavy tasks such as high-resolution rendering or complex shader workloads do not starve for memory. The card also offers four DisplayPort 2.0 outputs, enabling multi-monitor setups, and is built as a single-slot card with a 254 mm length, suitable for compact desktop systems.

The Intel Arc Graphics 2 Xe Mobile wins on efficiency and integration. Its 25 W TDP is exactly one-third of the A380E's 75 W TDP, making it suitable for thin-and-light portable devices where power draw and heat dissipation are critical constraints. As an IGP, it requires no power connectors and occupies no expansion slot, and its dimensions are not specified in the database, indicating that it is soldered directly to the motherboard. The mobile part also has a higher boost clock of 2500 MHz, which allows it to burst to higher frequencies for short-duration tasks, though this does not compensate for its smaller execution engine. Its production status is Active, while the A380E is End-of-life, suggesting a longer availability horizon for the mobile part.

Specification Differences

The two GPUs differ in nearly every fundamental specification. The A380E is built on a 6 nm process at TSMC, with 7,200 million transistors on a 157 mm² die, yielding a density of 45.9M / mm². The 2 Xe Mobile uses a 3 nm process at Intel, with transistor count and die size listed as unknown in the database. The A380E has 1024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. The 2 Xe Mobile has 256 shading units, 16 TMUs, 8 ROPs, and 2 ray tracing cores, exactly one-quarter of the A380E's execution resources.

Clock speeds differ substantially: the A380E runs at a flat 2000 MHz for both base and boost, while the 2 Xe Mobile runs at 300 MHz base and 2500 MHz boost. Memory is entirely different, with the A380E using 6 GB GDDR6 at 1937 MHz (15.5 Gbps effective) on a 96-bit bus, versus system-shared memory with no dedicated bandwidth figure for the mobile part. The A380E has a TDP of 75 W, a single-slot form factor, a PCIe 4.0 x8 interface, and a suggested PSU of 250 W. The 2 Xe Mobile has a TDP of 25 W, an IGP form factor, an IGP bus interface, and no suggested PSU. The A380E measures 254 mm in length, 127 mm in height, and 20 mm in width; the mobile part has no recorded dimensions. Display outputs are four DisplayPort 2.0 on the A380E versus portable-device-dependent outputs on the mobile part.

Architecture Differences

The architectural gap is generational and foundational. The A380E belongs to the Alchemist (Arc 3) generation, using the Xe-HPG architecture with the DG2-128 chip. The 2 Xe Mobile belongs to the Arc Graphics-M (Wildcat Lake) generation, using the Xe3-LPG architecture with the Wildcat Lake chip. Xe-HPG was Intel's first dedicated gaming GPU architecture, designed for discrete cards with a focus on raw throughput. Xe3-LPG is a low-power derivative of the Xe3 architecture, optimized for integrated graphics in mobile processors.

The process nodes diverge sharply: TSMC's 6 nm for the A380E versus Intel's 3 nm for the mobile part. The A380E packs 7,200 million transistors into a 157 mm² die, a density of 45.9M / mm². The mobile chip's transistor count and die size are unknown, but the 3 nm process allows for significantly higher density, meaning the 256 shading units likely occupy a much smaller area. The A380E has 8 ray tracing cores, while the 2 Xe Mobile has 2, a 4x difference that mirrors the shading unit ratio. Both parts support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, so API-level feature parity is maintained despite the architectural differences. The A380E's predecessor is Xe Graphics, and its successor is Battlemage; the 2 Xe Mobile's predecessor is HD Graphics-M, and it has no recorded successor.

The Verdict

The data clearly separates these two GPUs by design intent. The Intel Arc A380E is a discrete desktop card built for maximum performance within a 75 W envelope. It offers 4.096 TFLOPS of FP32 compute, 186.0 GB/s of dedicated GDDR6 bandwidth, and 8 ray tracing cores, all packed into a single-slot 254 mm card. It is the appropriate choice for a desktop system where a dedicated, low-profile GPU is needed for gaming or content creation, and where the 250 W suggested PSU is available.

The Intel Arc Graphics 2 Xe Mobile is an integrated processor designed for battery-powered portables. Its 25 W TDP and IGP form factor make it the only viable option for thin laptops or mini PCs where discrete graphics cannot fit. Its 256 shading units and 2 ray tracing cores deliver 1,280.0 GFLOPS of FP32 performance, which is modest but adequate for basic 3D acceleration, media playback, and light gaming at reduced settings. The system-dependent memory bandwidth is a limitation, but it is an acceptable trade-off for zero additional power draw and no physical footprint.

Users who need a discrete GPU with fixed memory bandwidth and a multi-display output should select the A380E, noting its end-of-life production status. Users who prioritize low power consumption and integration into a portable device should select the 2 Xe Mobile, which remains in active production. The performance gap of 3.2x in compute, texture, and pixel rates is substantial, but it is exactly the trade-off required for a 25 W IGP versus a 75 W discrete card. Both parts support the same modern APIs, so software compatibility is not a differentiator; the choice reduces to whether the workload demands dedicated memory and high throughput or minimal power draw and physical integration.
