Intel Arc A380M vs Intel Arc Graphics 4 Xe Mobile Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark runs between the Intel Arc A380M and the Intel Arc Graphics 4 Xe Mobile. Both entries have an average benchmark score of 0 and a percentile ranking of 50 among all GPUs. With zero recorded wins for either side, the comparison must rely entirely on the static specification data captured in the database.

The Intel Arc A380M delivers 4.096 TFLOPS of FP32 compute, while the Intel Arc Graphics 4 Xe Mobile produces 2.355 TFLOPS. That places the A380M roughly 74% ahead in raw single-precision throughput, a substantial gap. In FP16, the A380M reaches 8.192 TFLOPS versus 4.710 TFLOPS for the mobile part, again a clear advantage for the discrete card.

Pixel throughput tells a similar story. The A380M renders at 64.00 GPixel/s, compared to 36.80 GPixel/s for the integrated solution. Texture rate also favors the discrete card, with 128.0 GTexel/s versus 73.60 GTexel/s. These figures indicate the A380M can fill frames and apply textures roughly twice as fast in some workloads.

Clock behavior differentiates the two. The A380M has a base clock of 1550 MHz and a boost of 2000 MHz. The Arc Graphics 4 Xe Mobile idles at a much lower 300 MHz base but boosts to 2300 MHz, 300 MHz higher than the discrete part. This suggests the integrated GPU relies on aggressive boost behavior to close the gap, while the A380M maintains higher sustained clocks.

Memory configuration is perhaps the largest structural difference. The A380M uses 6 GB of dedicated GDDR6 across a 96-bit bus, yielding 186.0 GB/s of bandwidth. The Arc Graphics 4 Xe Mobile shares system memory, with its bandwidth listed as system dependent. The integrated GPU cannot match the dedicated memory bandwidth of the discrete card, which limits its performance in memory-intensive tasks such as high-resolution textures or large buffer operations.

Shader resources also diverge. The A380M contains 1024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. The Arc Graphics 4 Xe Mobile has half of each: 512 shading units, 32 TMUs, 16 ROPs, and 4 ray tracing cores. The A380M delivers the same architecture features, including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the feature set is consistent, but the execution resources are doubled on the discrete side.

The Verdict

From the recorded data, the Intel Arc A380M is the stronger performer on every measurable compute and memory metric. It doubles the shading units, TMUs, ROPs, and ray tracing cores of the Arc Graphics 4 Xe Mobile. It offers 4.096 TFLOPS FP32 against 2.355 TFLOPS, and 186.0 GB/s of dedicated memory bandwidth versus a system-shared pool. The A380M also draws 35 W, while the integrated part consumes 25 W, so the performance advantage comes with a 10 W higher power envelope.

The Arc Graphics 4 Xe Mobile does hold one clear advantage: clock speed. Its 2300 MHz boost exceeds the A380M's 2000 MHz boost by 300 MHz. The integrated part also uses a 3 nm process node from Intel, whereas the A380M uses a 6 nm node from TSMC. The smaller process node and higher boost clock suggest the integrated design achieves its performance with greater efficiency per clock, but the raw resource deficit remains decisive.

Benchmark results, or the absence of them, leave no direct validation of real-world gaming or compute workloads. The specification data alone points to the A380M as the more capable part for tasks that scale with shading units, memory bandwidth, and fill rates. The Arc Graphics 4 Xe Mobile appears positioned for systems where power draw and physical integration matter more than peak throughput.

Where Each One Wins

The Intel Arc A380M wins in scenarios that demand sustained compute throughput. Its 1024 shading units handle parallel workloads such as rendering, simulation, and general compute more effectively than 512 units. The 186.0 GB/s dedicated bandwidth supports high-resolution textures, large framebuffers, and data-heavy shaders without contending with the CPU for memory access. The 64 TMUs and 32 ROPs deliver higher texture and pixel fill rates, which benefit games with complex materials and high display resolutions.

The Arc Graphics 4 Xe Mobile wins in power-constrained and space-constrained designs. At 25 W, it draws 10 W less than the A380M, making it suitable for thin laptops where thermal and battery budgets are tight. As an IGP with no power connectors and no separate module slot, it integrates directly into the processor package, eliminating the need for discreet board space. Its higher boost clock of 2300 MHz may also help in short, bursty workloads where thermal headroom allows the GPU to ramp up, but the lower base clock of 300 MHz indicates it cannot sustain that pace under load.

The A380M's MXM module form factor suits upgradeable laptops or compact embedded systems where a replaceable graphics card is desirable. The integrated part suits devices where the GPU is fixed and cannot be serviced, and where system memory serves as the only memory pool. For users who need predictable memory bandwidth and dedicated VRAM, the A380M is the clear choice. For users who need low power draw and zero add-in card complexity, the Arc Graphics 4 Xe Mobile fits better.
