Intel Core i3-1125G4

The Intel Core i3-1125G4 is a power-efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation (UP4) that was introduced in September 2020. It integrates four Willow Cove processor cores (8 threads thanks to HyperThreading). Each core can clock from 2 GHz (guaranteed base speed) to 3.7 GHz (single-core boost). All cores at once can clock at up to 3.3 GHz. The faster Core i7 models offer more Level 3 cache (12 versus 8 MB in the i5) and higher clocked cores.

Another novelty is the integrated Xe graphics card based on the completely new Gen 12 architecture. In the i3-1125G4 Intel is naming the GPU UHD Graphics and offers only 48 of the 96 EUs clocked at 400 – 1250 MHz. The GPU and CPU can together use the 8 MB of L3 cache.

Furthermore, Tiger Lake SoCs add PCIe 4 support (four lanes), AI hardware acceleration, and the partial integration of Thunderbolt 4 / USB 4 and Wi-Fi 6 in the chip.

The chip is produced in the improved 10nm+ process (called SuperFin) at Intel that should be comparable to the 7nm process at TSMC (e.g. Ryzen 4000 series).

The operating range of the UP3 series is specified at 12 to 28 Watt. Therefore, the processor is also suited for thin and light laptops.
