Intel Core i3-1120G4 vs Intel Core i7-1180G7
Intel Core i3-1120G4
► remove from comparisonThe Intel Core i3-1120G4 is a power-efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation (UP4) that was introduced in September 2020. It integrates four Willow Cove processor cores (8 threads thanks to Hyper-Threading). Each core can clock from 1.1 GHz (base speed) to 3.5 GHz (1 core boost). All cores at once can clock at up to 3 GHz.
Another novelty is the integrated Xe graphics adapter based on the completely new Gen 12 architecture. The i3 integrates the low end UHD Graphics G4 with 48 of the 96 EUs enabled and a clock speed of 400 - 1100 MHz. The GPU and CPU can together use the 8 MB of L3 cache.
Furthermore, Tiger Lake SoCs add PCIe 4 support (4 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 system built around the 1120G4 as of August 2023, it's fair to expect the chip to be about half as fast as the Core i5-1125G4 (Tiger Lake, 4 cores, 8 threads, up to 3.7 GHz), as far as multi-thread benchmarks are concerned. The 1120G4's low TDP target is slated to limit the chip's real-world Boost clock speeds significantly leading to underwhelming performance and high DPC latencies.
Power consumption
This Core i3 has a default TDP of 7 W to 15 W, the expectation being that laptop manufacturers will go for a higher value in exchange for higher performance. The CPU is built with Intel's third-gen 10 nm process marketed as SuperFin for decent, as of late 2022, energy efficiency.
Intel Core i7-1180G7
► remove from comparisonThe Intel Core i7-1180G7 is a power-efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation (UP4) that was introduced in early 2021. It integrates four Willow Cove processor cores (8 threads thanks to Hyper-Threading). The guaranteed base clock speed depends on the TDP setting and can range from 0.9 (7 W TDP) to 2.2 GHz (15 W TDP). The Turbo clock speed is specified at 4.6 GHz for one core, all cores can reach up to 3.7 GHz.
Another novelty is the integrated Xe graphics card with 96EUs based on the completely new Gen 12 architecture. It offers a significantly higher performance compared to the older Iris Plus G7 (Ice Lake). The GPU and CPU can together use the 12 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 i5-1140G7 also supports the management feature vPro.
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 UP4 series is specified at 7 to 15 Watt. Therefore, the processor is well suited for very thin and light laptops, convertibles or tablets.
