Intel Core i5-1155G7 vs Mediatek MT8127

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.

Mediatek MT8127

The MediaTek MT8127 is a cheap ARM-SoC (System on a Chip) that is mainly used in Android based tablets. It is manufactured in 28 nm and integrates a quad-core ARM Cortex-A7 processor clocked at 1.5 GHz (typically), a ARM Mali-450 MP4 graphics card (at 600 MHz) and a single channel 32 Bit DDDR3-1333 memory controller (max. 5.3 GB/s).

Processor

The ARM Cortex-A7 design is a 32-Bit entry level core with a much lower performance per MHz than the Cortex-A9. Therefore, the MT8127 is only positioned in the lower mid-range similar to the Qualcomm Snapdragon 400.

Features

The MT8127 integrates function blocks for full HD videos (en- and decoders), WiFi, Bluetooth 4.0, GPS and FM radio. Camera modules are supported up to 13 MP.

Power Consumption

Due to the low clocked Cortex-A7 cores and the small GPU, the SoC is using not much power and therefore also suited for small tablets.
