The Mediatek MT8121 is a low-cost ARM SoC (System on a Chip) mainly used in tablets. It is manufactured in 28 nm and integrates a quad-core Cortex-A7 processor and a PowerVR SGX 544 GPU. The CPU cores are typically clocked at 1.3 GHz while the GPU is clocked at 156 MHz.
Performance
Since the Cortex-A7 architecture is somewhat slower than a Krait or Cortex-A9 design at the same clock speeds, the performance of the MT8121 is just below Nvidia's Tegra 3 or the Samsung Exynos 4412. The PowerVR SGX 544 is also just a low-cost solution not designed for ultra-high resolution displays or very demanding games.
Features
In addition to the processor and GPU, the SoC integrates a decoder for 1080p video, WiFi, Bluetooth 4.0 as well as GPS, but lacks a 2G/3G/4G radio. Cameras are supported up to a resolution of 13 MP.
Power consumption
Thanks to the energy-efficient A7 cores and 28 nm manufacturing, the power consumption is likely very low and suitable for even smaller tablets.
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 MT6580M is a system-on-a-chip (SoC) for low-cost tablets and smartphones. It is manufactured in 28 nm and offers a quad-core Cortex-A7 processor (max 1.3 GHz) as well as an ARM Mali-400 MP2 GPU (MP2 unconfirmed, but the similar MT6582 has a MP2 clocked at 416 MHz). Furthermore, the chip supports dual SIM, UMTS and HSPA+, WiFi, FM, Bluetooth and GPS.
The CPU performance of the MT6580M is similar to other Cortex-A7 SoCs clocked at the same frequency. Depending on the benchmark, the CPU power is roughly comparable with the Nvidia Tegra 3 and sufficient for everyday applications such as browsing. The GPU will handle only simple Android games in moderate resolutions.
