Intel Arc A380E x2 vs Intel Arc Graphics 2 Xe Mobile Comparison

Where Each One Wins

The benchmark data splits these two Intel graphics solutions into completely different usage categories. The Intel Arc A380E x2 is a discrete, single-slot add-in card built around the DG2-128 chip with 1024 shading units, 64 texture mapping units, and 32 raster operation units. It delivers 4.096 TFLOPS of FP32 compute and 8.192 TFLOPS of FP16 performance. The Intel Arc Graphics 2 Xe Mobile is an integrated graphics processor on the Wildcat Lake chip, with 256 shading units, 16 TMUs, and 8 ROPs, producing 1,280.0 GFLOPS FP32 and 2.560 TFLOPS FP16.

The compute gap is decisive. The A380E x2 offers 3.2 times the FP32 throughput of the mobile part. In raw shader work, pixel fill, and texture processing, the discrete card dominates. Its pixel rate of 64.00 GPixel/s is 3.2 times the 20.00 GPixel/s of the integrated solution. Texture rate of 128.0 GTexel/s is likewise 3.2 times the 40.00 GTexel/s from the mobile GPU.

Where the mobile part wins is efficiency and integration. The 25 W TDP of the Arc Graphics 2 Xe Mobile compares to a 130 W TDP for the A380E x2. The integrated GPU requires no power connectors, no slot width, and no external PSU recommendation. It fits into a portable device with system-shared memory, making it the only option for thin-and-light hardware. The A380E x2, with its 1x 6-pin power connector, 300 W suggested PSU, and 265 mm length, is a board-level product for desktop or server chassis.

Clock behavior also favors the mobile chip in burst scenarios. The Arc Graphics 2 Xe Mobile has a 300 MHz base clock but boosts to 2500 MHz, a wide dynamic range. The A380E x2 holds a flat 2000 MHz base and boost. In short-duration workloads, the mobile part can exceed its sustained-class performance envelope, while the discrete card maintains a constant 2000 MHz.

Architecture Differences

The two GPUs come from different architectural generations and foundries. The A380E x2 uses the Xe-HPG architecture on the DG2-128 chip, part of the Alchemist (Arc 3) generation. It is fabricated on a 6 nm process at TSMC, with 7,200 million transistors on a 157 mm² die, yielding a transistor density of 45.9M per mm². The mobile part uses Xe3-LPG architecture on the Wildcat Lake chip, from the Arc Graphics-M (Wildcat Lake) generation, built on a 3 nm process at Intel. Transistor count and die size are not recorded in the database for the mobile chip.

The memory subsystem is fundamentally different. The A380E x2 has 6 GB of dedicated GDDR6 memory on a 96 bit bus, delivering 186.0 GB/s of bandwidth. Memory clock is 1937 MHz, equivalent to 15.5 Gbps effective. The Arc Graphics 2 Xe Mobile uses system-shared memory, with bus width, type, and bandwidth all listed as system dependent. This means the integrated GPU shares the host's memory controller and DRAM, so achievable bandwidth varies by platform.

Ray tracing hardware scales accordingly. The discrete card has 8 ray tracing cores; the mobile chip has 2. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so feature-level API support is identical. The A380E x2 outputs to 8x mini-DisplayPort 2.0 connectors, while the mobile GPU's display outputs are portable device dependent.

The A380E x2 uses a PCIe 4.0 x8 bus interface, while the mobile part is an IGP with no bus interface in the traditional sense. Production status differs: the A380E x2 is end-of-life, with a successor listed as Battlemage, while the Arc Graphics 2 Xe Mobile is active with no successor recorded. The discrete card's predecessor is Xe Graphics; the mobile chip's predecessor is HD Graphics-M.

The Verdict

The data defines two distinct purchasing and integration paths. For any system requiring sustained 3D rendering, compute throughput, or multi-display output, the Intel Arc A380E x2 is the only choice between these two. It provides 4.096 TFLOPS FP32, 64.00 GPixel/s fill rate, 6 GB dedicated GDDR6, and 8 display outputs. Its 130 W TDP and single-slot form factor make it suitable for workstations or compact desktops where the chassis can handle a 265 mm card and a 300 W PSU recommendation.

For portable devices, the Intel Arc Graphics 2 Xe Mobile is the only viable option. It consumes 25 W, requires no additional power connectors, and uses system-shared memory, which is mandatory for thin laptops and mini PCs. Its 2500 MHz boost clock provides responsive graphics for light 3D loads, and its 2 ray tracing cores deliver API-level ray tracing support despite the lower raw throughput.

The A380E x2 is end-of-life, so the recorded data indicates no further production. The mobile part is active and scheduled for a 2026-04-15 release date. Anyone designing a new system with long-term availability requirements should note that the discrete card is already discontinued, while the integrated GPU is current. The predecessor and successor chain also differs: the A380E x2 follows Xe Graphics and leads to Battlemage, whereas the mobile chip follows HD Graphics-M with no successor listed.

Head-to-Head Benchmarks

The recorded benchmark data shows no direct head-to-head benchmark entries between these two GPUs, and neither has individual benchmark scores or nearest rivals in the database. The comparison must therefore rest on the specification-derived performance indicators.

The largest win for the A380E x2 is in FP32 compute. At 4.096 TFLOPS versus 1,280.0 GFLOPS, the discrete card achieves exactly 3.2 times the throughput. That ratio holds for FP16 as well: 8.192 TFLOPS against 2.560 TFLOPS. The consistency of this 3.2 multiplier across compute, pixel rate, and texture rate indicates that the two designs scale linearly in shader count: 1024 shading units versus 256, 64 TMUs versus 16, and 32 ROPs versus 8.

Memory bandwidth is the second major separation. The A380E x2 offers 186.0 GB/s from dedicated GDDR6, while the mobile GPU's bandwidth is system dependent. In a typical portable platform with shared LPDDR memory, the discrete card's dedicated bandwidth will be substantially higher, though the exact comparison depends on the host system.

The Arc Graphics 2 Xe Mobile wins on clock speed range. Its 2500 MHz boost clock exceeds the A380E x2's 2000 MHz boost by 25%. The 300 MHz base clock versus 2000 MHz base means the mobile part can idle far lower, contributing to its 25 W TDP. The discrete card's flat 2000 MHz clock profile is designed for consistent sustained output rather than burst responsiveness.

The mobile GPU also wins on process technology. The 3 nm Intel node is two generations ahead of the 6 nm TSMC node used for the A380E x2. While transistor counts and die sizes are unknown for the mobile chip, the smaller node allows the 25 W power envelope with a 2500 MHz boost clock.

The A380E x2 wins on display connectivity. Its 8x mini-DisplayPort 2.0 outputs allow multi-monitor configurations that the portable-device-dependent outputs of the mobile GPU cannot match in a fixed installation. The discrete card's PCIe 4.0 x8 interface also provides a dedicated data path, whereas the IGP relies on the host's integrated memory controller.

Specification Differences

The two GPUs differ in every major specification category. The A380E x2 uses the DG2-128 chip with Xe-HPG architecture from the Alchemist (Arc 3) generation. The Arc Graphics 2 Xe Mobile uses the Wildcat Lake chip with Xe3-LPG architecture from the Arc Graphics-M (Wildcat Lake) generation. Process nodes are 6 nm TSMC versus 3 nm Intel.

Shading units number 1024 versus 256, TMUs 64 versus 16, ROPs 32 versus 8, and ray tracing cores 8 versus 2. The A380E x2 has 6 GB GDDR6 on a 96 bit bus with 186.0 GB/s bandwidth; the mobile chip uses system-shared memory with system-dependent characteristics. Clocks are 2000 MHz base and boost for the discrete card versus 300 MHz base and 2500 MHz boost for the mobile part.

Power and physical specifications diverge sharply. The A380E x2 is a single-slot card at 130 W TDP with a 1x 6-pin connector and 300 W suggested PSU. The Arc Graphics 2 Xe Mobile is an IGP at 25 W TDP with no connectors and no PSU suggestion. The discrete card measures 265 mm by 127 mm by 20 mm; the mobile part has no recorded dimensions.

The A380E x2 uses PCIe 4.0 x8 and outputs 8x mini-DisplayPort 2.0. The mobile GPU is IGP-based with portable-device-dependent display outputs. Transistor count and die size are recorded only for the discrete card: 7,200 million transistors on 157 mm² with 45.9M per mm² density. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Production status is end-of-life for the A380E x2 and active for the mobile chip, with release dates of 2024-03-31 and 2026-04-15 respectively.
