MagyarIntel Core i3-1125G4 vs Intel Core i5-1155G7
Intel Core i3-1125G4
► remove from comparison
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.
The chip is produced on 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.
Intel Core i5-1155G7
► remove from comparisonThe Intel Core i5-1155G7 is a power efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation that was announced in mid 2021 as part of the refresh. It integrates four Willow Cove processor cores (8 threads thanks to HyperThreading). The base clock speed depends on the TDP settings and ranges from 1 GHz (12 Watt TDP) up to 2.5 GHz (28 Watt). The Boost is always specified at 4.5 GHz.
Another novelty is the integrated Xe graphics card with 80 EUs based on the completely new Gen 12 architecture. It offers a significantly higher performance compared to the older Iris Plus G7 (Ice Lake).
Furthermore, Tiger Lake SoCs add PCIe 4 support (4 lanes), AI hardware acceleration, and the partial integration of Thunderbolt 4 / USB 4 and Wifi 6 in the chip.
The chip is produced in the improved 10nm SuperFin process at Intel that should be comparable to the 7nm process at TSMC (e.g. Ryzen 4000 series).
