A: Both the Intel Arc Graphics 1 Xe Mobile and the Intel Arc Graphics 4 Xe Mobile have a TDP of 25 W. Neither requires external power connectors, and both use an IGP bus interface.

The Verdict

The data presents a clear performance hierarchy. The Intel Arc Graphics 4 Xe Mobile is the stronger part in every measurable compute category. It quadruples the shading units, texture units, render output units, and ray tracing cores of the 1 Xe variant. Its FP32 throughput of 2.355 TFLOPS is exactly four times the 588.8 GFLOPS of the smaller chip. For any workload that scales with execution resources, the 4 Xe is the definitive choice.

The Intel Arc Graphics 1 Xe Mobile, with its 128 shading units and 4 render output units, is the more modest option. It still supports the same modern API feature set, including DirectX 12 Ultimate and Vulkan 1.4, and runs at the same 2300 MHz boost clock. This makes it suitable for basic graphics acceleration and lighter tasks where the full 4 Xe resources are unnecessary. Both parts share a 25 W TDP, so power draw does not differentiate them. The 1 Xe is the lighter-duty part, while the 4 Xe is the one to select when maximum integrated performance is required.

Head-to-Head Benchmarks

The recorded data shows no direct benchmark scores for either product in the head-to-head comparison, and neither has an average benchmark score. However, the specification-derived rates provide a clear picture of relative performance. The pixel rate of the 4 Xe is 36.80 GPixel/s, exactly four times the 9.200 GPixel/s of the 1 Xe. Texture rate follows the same pattern: 73.60 GTexel/s versus 18.40 GTexel/s. This 4x scaling is consistent across all execution units.

The FP32 compute difference is the most significant single metric. The 4 Xe delivers 2.355 TFLOPS, which is four times the 588.8 GFLOPS of the 1 Xe. In FP16, the 4 Xe reaches 4.710 TFLOPS versus 1,177.6 GFLOPS. These figures indicate that any shader-heavy or compute-oriented workload will see a proportional benefit from the 4 Xe configuration. The ray tracing cores also scale from 1 in the 1 Xe to 4 in the 4 Xe, suggesting a fourfold increase in ray tracing capacity. With identical clock speeds and memory architecture, the performance gap is entirely attributable to the doubling of execution resources across the board.

Specification Differences

The two GPUs differ in several key specification areas. The shading unit count is 128 for the 1 Xe and 512 for the 4 Xe. Texture mapping units are 8 versus 32. Render output units are 4 versus 16. Ray tracing cores are 1 versus 4. These resource counts directly produce the measured performance rates: pixel rate of 9.200 GPixel/s versus 36.80 GPixel/s, texture rate of 18.40 GTexel/s versus 73.60 GTexel/s, FP32 of 588.8 GFLOPS versus 2.355 TFLOPS, and FP16 of 1,177.6 GFLOPS versus 4.710 TFLOPS.

The chip and generation also differ. The 1 Xe uses the Wildcat Lake chip in the Arc Graphics-M (Wildcat Lake) generation. The 4 Xe uses the Panther Lake chip in the Arc Graphics-M (Panther Lake) generation. The release dates differ as well, with the 4 Xe releasing on 2026-01-26 and the 1 Xe releasing later on 2026-04-15. The 1 Xe lists a predecessor of HD Graphics-M, while the 4 Xe has no predecessor listed.

Shared specifications include the Xe3-LPG architecture, 3 nm process node, Intel foundry, 300 MHz base clock, 2300 MHz boost clock, System Shared memory, 25 W TDP, IGP slot width, no power connectors, Portable Device Dependent display outputs, and identical API support. Transistor count and die size are unknown for both.

Architecture Differences

Both GPUs are built on the Xe3-LPG architecture, which represents the third generation of Intel's low-power graphics architecture. The process node is identical at 3 nm, and both are manufactured by Intel. The architectural foundation is the same, meaning instruction sets and feature support are consistent between the two.

The core difference lies in the execution resource configuration. The 4 Xe variant has four times the shading units, texture units, render output units, and ray tracing cores. This indicates a physically larger GPU die with more compute clusters enabled. The chip selection differs, with Wildcat Lake powering the 1 Xe and Panther Lake powering the 4 Xe, though both are integrated into the same 25 W power envelope.

Memory architecture is identical: System Shared memory with System Dependent bandwidth. This means both GPUs rely on the host system's memory, and performance will vary based on the platform's memory configuration. The display outputs are also Portable Device Dependent for both, indicating they are designed for mobile platforms. The ray tracing core count difference, from 1 to 4, suggests the 4 Xe has greater capacity for hardware-accelerated ray tracing workloads, though the identical architecture means the feature set is the same.

Where Each One Wins

The Intel Arc Graphics 4 Xe Mobile wins in every performance category measured. Its 2.355 TFLOPS FP32 throughput is four times that of the 1 Xe, making it the clear choice for GPU compute tasks, shader-heavy rendering, and any workload that scales with execution units. The 36.80 GPixel/s pixel rate and 73.60 GTexel/s texture rate give it a substantial advantage in fill-rate-bound scenarios. The 4 ray tracing cores versus 1 provide a fourfold increase in ray tracing capacity, making it the better option for games or applications that utilize DirectX 12 Ultimate features.

The Intel Arc Graphics 1 Xe Mobile wins in the context of resource efficiency for lighter workloads. With the same 25 W TDP and identical clock speeds, it delivers the same API feature set at a quarter of the execution resource count. For basic display output, video playback, and light 2D workloads, the 1 Xe provides adequate performance without the overhead of unused execution units. The 1 Xe also has a later release date of 2026-04-15, indicating it may be paired with different platform configurations than the 4 Xe.

In practical terms, the 4 Xe is the performance winner across all compute and graphics metrics. The 1 Xe is the more restrained option, suited for systems where the full 4 Xe resource allocation is not necessary. Since both share the same power budget and memory architecture, the choice comes down to whether the workload demands the 4x execution resource advantage of the 4 Xe or is satisfied with the 1 Xe's more modest configuration.
