Intel Core i5-1140G7 vs Intel Core i5-1155G7 vs Intel Core i7-1180G7

Intel Core i5-1140G7

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.

Intel Core i5-1155G7

The Intel Core i5-1155G7 is a power efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation that was announced in mid 2021 as part of the refresh. 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 GHz (12 Watt TDP) up to 2.5 GHz (28 Watt). Boost clock speed is 4.5 GHz.

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.

Another novelty is the integrated Xe graphics adapter 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).

Performance

The average 1155G7 in our database proves to be a very decent mid-range processor, as of mid 2022, trading blows with the Core i7-10810U and the Ryzen 5 4500U as far as multi-thread benchmark scores are concerned. While perhaps not the best option for power users, this Core i5 will make most consumers happy, providing for short load times and generally pain-free experience.

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 series chip has a default TDP, also known as the long-term power limit, 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, this is a tad too high to allow for passively cooled designs.

The i5-1155G7 is built with Intel's third-gen 10 nm process marketed as SuperFin for lower-than-average, as of early 2023, energy efficiency.

Intel Core i7-1180G7

The 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.
