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.
The Mediatek MT6589T is a low-end system-on-a-chip (SoC) found in many inexpensive smartphones. It is manufactured in 28 nm and integrates a Cortex-A7-based quad-core CPU clocked at 1.5 GHz, a PowerVR SGX544 GPU clocked at 357 MHz, dual SIM and UMTS/HSPA+ support (up to 21 Mbps) and 1080p30 video decoding and encoding.
Both the CPU and GPU offer performances similar to an Nvidia Tegra 3 or the Samsung Exynos 4412 and Mali-400 GPU. Performance-per-clock of the Cortex-A7 is only slightly below that of a Cortex-A9, which can be found in the two aforementioned rivals. The graphics unit offers sufficient power for multimedia tasks and simple games, but not for extremely high resolution displays or complex 3D graphics.
Thanks to the modern 28 nm manufacturing and comparatively low performance, the power consumption of the entire chip is likely very low in order to be compatible with smaller smartphones and battery capacities.
