Intel 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 of the Tiger Lake family (UP3) that was introduced in September 2020. It integrates four Willow Cove processor cores (8 threads thanks to Hyper-Threading). 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.
Performance
While we have not tested a single laptop built around the 1125G4 as of October 2023, we expect the chip's multi-thread performance to be 10% to 20% lower than that of the Core i5-1135G7 (4 cores, 8 threads, somewhat higher clock speeds).
Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.
Power consumption
This Core i3 series chip has a default TDP of 12 W to 28 W, the expectation being that laptop makers 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.
The i3-1125G4 is manufactured on Intel's third-gen 10 nm process marketed as SuperFin for average, as of early 2023, energy efficiency.
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). Boost clock speed is 4.5 GHz.
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.
Another novelty is the integrated Xe graphics adapter 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).
Performance
The average 1155G7 in our database proves to be a very decent mid-range processor, as of mid 2022, trading blows with the Core i7-10810U and the Ryzen 5 4500U as far as multi-thread benchmark scores are concerned. While perhaps not the best option for power users, this Core i5 will make most consumers happy, providing for short load times and generally pain-free experience.
Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.
Power consumption
This Core i5 series chip has a default TDP, also known as the long-term power limit, of 12 W to 28 W, the expectation being that laptop makers will go for a higher value in exchange for higher performance. Either way, this is a tad too high to allow for passively cooled designs.
The i5-1155G7 is built with Intel's third-gen 10 nm process marketed as SuperFin for lower-than-average, as of early 2023, energy efficiency.
