Intel Core i3-1125G4

The Intel Core i3-1125G4 is a 28 W quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation (UP3) 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 @ 28 W) 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 GPU based on the completely new Gen 12 architecture. In the i3-1125G4 Intel names 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.
Power consumption
This Core i3 has a default TDP of 12 W to 28 W, the expectation being that laptop manufacturers will go for a higher value in exchange for higher performance. Either way, that's a little too high to allow for passively cooled designs.
Intel Core i5-1125G4 is manufactured on Intel's second-gen 10 nm process marketed as SuperFin for decent, as of late 2022, energy efficiency.
