Intel Core i5-1145G7 vs Intel Core i7-11390H

Intel Core i5-1145G7

The Intel Core i5-1145G7 is a power efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation that was announced early 2021. It integrates four Willow Cove processor cores (8 threads thanks to HyperThreading). The base clock speed depends on the TDP settings and ranges from 1.1 GHz (12 Watt TDP) up to 2.6 GHz (28 Watt). The Boost is always specified at 4.4 GHz (one or two cores).

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. In addition to this, the i5 supports vPro for easy remote management.

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

Intel Core i7-11390H

The Intel Core i7-11390H is a high-end quad-core SoC for thin and light gaming laptops and mobile workstations. It is based on the Tiger Lake H35 generation and was announced in mid-2021 as a refresh. It integrates four Willow Cove processor cores (8 threads thanks to HyperThreading). The base clock speed depends on the TDP setting and can vary from 2.9 (28 W TDP) to 3.4 GHz (35 W). Compared to the i7-11375H, the 11390H can now also boost with two cores up to 5 GHz and all four cores can reach a 300 MHz higher clock speed of 4.6 GHz. Both i7 use the whole 12 MB level 3 cache.

The SoC also includes the improved Xe iGPU with all 96 EUs enabled clocked at up to 1400 MHz.

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

The average 11390H in our database matches the AMD Ryzen 5 4600U and the Intel Core i7-10710U in multi-thread performance to be a decent mid-range chip, as of late 2021 - provided one isn't too picky when it comes to load times.

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 i7 series chip has a default TDP of 28 W to 35 W, the expectation being that laptop makers will go for a higher value in exchange for higher performance. Either way, a proper coolu\ing solution is a must.

The CPU is built with Intel's third-gen 10 nm manufacturing process marketed as SuperFin for lower-than-average, as of mid 2023, energy efficiency.
