The Intel Core i5-1140G7 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 1.2 GHz (base speed) to 4.2 GHz (1 core boost). All cores at once can clock at up to 3.4 GHz. At the time of announcement, the i7-1185G7 is the fastest model of UP4 low power series.
Another novelty is the integrated Xe graphics card based on the completely new Gen 12 architecture. It should offer a significantly higher performance compared to the older Iris Plus G7 (Ice Lake). In the i5-1140G7 it uses 96 EUs and clocks at 400 – 1100 MHz. The GPU and CPU can together use the 12 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 UP4 series is specified at 7 to 15 Watt. Therefore, the processor is well suited for very thin and light laptops, convertibles or tablets.
