Intel Core i3-1115G4 vs Intel Core i7-11375H

Intel Core i3-1115G4

The Intel Core i3-1115G4 is a dual-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation (UP3) that was launched in September 2020. It integrates two Willow Cove processor cores (4 threads thanks to HyperThreading). Each core can clock from 3 GHz (base speed) to 4.1 GHz (single- and dual-core boost). The faster Core i5 and i7 models offer more cores and are therefore significantly faster.

Another novelty is the integrated Xe graphics card based on the completely new Gen 12 architecture. In the i3-1115G4 Intel is naming the GPU UHD Graphics and offers only 48 of the 96 EUs clocked at 400 - 1250 MHz. GPU and CPU can together use the 6 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 WiFi 6 in the chip.

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

Performance

Multi-thread peformance is most comparable to what the Intel Core i5-8250U and the AMD Ryzen 5 3450U deliver. This makes the i3 a more than decent option for day-to-day tasks; that said, any workload of the more taxing kind (such as exporting a high-bitrate, hour long UHD video) will be enough to bring the i3 to its knees.

Thanks to its decent cooling solution and a long-term CPU power limit of 25 W, the ThinkPad L15 G2-20X4S0KU00 is one of the fastest laptops powered by the 1115G4 we know of. It can be more than 20% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

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 tad too high to allow for passively cooled laptops, tablets, mini-PCs.

The Core i3-1115G4 is built with Intel's third-gen 10 nm process marketed as SuperFin for decent, as of mid 2022, energy efficiency.

Intel Core i7-11375H

The Intel Core i7-11375H 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 early 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 3 (28 W TDP) to 3.3 GHz (35 W). Compared to the i7-11370H, the only difference is the additional Turbo Boost 3.0 for a single core. With it, the 11375H can clock up to 5 GHz. Two cores can clock up to 4.8 GHz (as the 11370H) and all four cores can reach up to 4.3 GHz. The 11375H can use the whole 12 MB level 3 cache.

The processor performance of the i7 should be very similar to the i7-11370H. Only single threaded short workloads will be slightly faster. The multi-threaded performance should be clearly higher than the old Core i5-10400H (Comet Lake, fastest quad core of the 10th gen) due to the new processor architecture. The similar Core i7-1185G7 offers similar specs as the 11370H but a lower TDP and therefore also lower (sustained) performance.

The SoC also included the improved Xe graphics adapter with all 96 EUs 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).
