The Intel Core i5-1140G7 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 0.8 (7 W TDP) to 1.8 GHz (15 W TDP). The Turbo clock speed is specified at 4.2 GHz for one core, all cores can reach up to 3.5 GHz.
Another novelty is the integrated Xe graphics card with 80EUs based on the completely new Gen 12 architecture. It offers a significantly higher performance compared to the older Iris Plus G7 (Ice Lake). In the i5-1140G7 it uses 80 of the 96 EUs and clocks between 400 - 1100 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. The i5-1140G7 also supports the management feature vPro.
Performance
The average 1140G7 in our database is in the same league as the N95 and also the Pentium 7505, as far as multi-thread benchmark scores are concerned. This is a pretty poor result, as of early 2023.
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 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. Those values are rather low, meaning at least a few passively cooled designs are to be expected.
Core i5-1140G7 is manufactured on Intel's 2nd generation 10 nm process marketed as SuperFin for decent, as of early 2023, energy efficiency.
The Intel Core i7-3630QM is a fast quad-core processor for laptops based on the Ivy Bridge architecture and successor of the i7-3630QM. Due to Hyperthreading, the four cores can handle up to eight threads in parallel leading to better utilization of the CPU. Each core offers a base speed of 2.4 GHz but can dynamically increase clock rates with Turbo Boost up to 3.2 GHz (for 4 active cores), 3.3 GHz (for 2 active cores) and 3.4 GHz (for 1 active core).
Ivy Bridge is an enhanced die shrink of the Sandy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm (versus 32nm Sandy Bridge CPUs) and are the first to introduce 3D transistors for increased energy efficiency when compared to similarly clocked Sandy Bridge processors. Other new features are integrated PCI Express 3.0 and DDR3(L)-1600 support. Except VT-d and vPro the 3630QM supports all functions of the Ivy Bridge core like VT-x, AES or Trusted Execution.
The performance of the Core i7-3630QM should be slightly above a similarly clocked Sandy Bridge processor due to slight architectural improvements. As a result, overall performance should be above the former fastest model, the Core i7-2920XM.
The integrated Intel HD Graphics 4000 offers 16 Execution Units (EUs) clocked at 650 MHz up to 1150 MHz with Turbo Boost, making it one of the faster variants.
As with most quad-core Ivy Bridge models, the Core i7-3630QM is specified at a TDP of 45 Watts including graphics card and memory controller. Therefore, the CPU is well-suited for laptops 15-inches or greater.
The 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.
