Intel Core i7-11390H vs Intel Core i5-11320H

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.

Intel Core i5-11320H

The Intel Core i5-11320H is a mid range SoC for thin and light gaming laptops and mobile workstations. It is based on the Tiger Lake H35 refresh generation and will be announced in Q3 2021. 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 2.5 (28 W TDP) to 3.2 GHz (35 W). The boost of a single and two cores under load can reach up to 4.5 GHz. All four cores can reach up to 4.3 GHz. The L3 cache is reduced to 8 MB compared to the 12 MB of the higher end i7 models.

Thanks to the improved clock speeds, the performance gap to the faster i7-11370H should be quite small. The i7 still offers higher single and dual core Turbo speeds and more L3 cache.

The SoC also included the improved Xe graphics card with 96 CUs clocked at up to 1350 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.

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