Intel Core i3-1115G4 vs Mediatek MT6592 vs Intel Core i5-1145G7

Intel Core i3-1115G4

The Intel Core i3-1115G4 is a dual-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation (UP3) that was launched in September 2020. It integrates two Willow Cove processor cores (4 threads thanks to HyperThreading). Each core can clock from 3 GHz (base speed) to 4.1 GHz (single- and dual-core boost). The faster Core i5 and i7 models offer more cores and are therefore significantly faster.

Another novelty is the integrated Xe graphics card based on the completely new Gen 12 architecture. In the i3-1115G4 Intel is naming the GPU UHD Graphics and offers only 48 of the 96 EUs clocked at 400 - 1250 MHz. GPU and CPU can together use the 6 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 WiFi 6 in the chip.

The chip is produced on the second-gen 10 nm Intel SuperFin process that should be comparable to the 7 nm TSMC process (e.g. Ryzen 4000 series).

Performance

Multi-thread peformance is most comparable to what the Intel Core i5-8250U and the AMD Ryzen 5 3450U deliver. This makes the i3 a more than decent option for day-to-day tasks; that said, any workload of the more taxing kind (such as exporting a high-bitrate, hour long UHD video) will be enough to bring the i3 to its knees.

Thanks to its decent cooling solution and a long-term CPU power limit of 25 W, the ThinkPad L15 G2-20X4S0KU00 is one of the fastest laptops powered by the 1115G4 we know of. It can be more than 20% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Core i3 series chip has a default TDP 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, that's a tad too high to allow for passively cooled laptops, tablets, mini-PCs.

The Core i3-1115G4 is built with Intel's third-gen 10 nm process marketed as SuperFin for decent, as of mid 2022, energy efficiency.

Mediatek MT6592

The MediaTek MT6592 is a mid-range 28 nm SoC for Android smartphones and tablets. It was announced near the end of 2013 and is manufactured in 28 nm. It includes 8 Cortex-A7 processor cores that are typically clocked up to 1.7 - 2.0 GHz. Furthermore, the SoC integrates an ARM Mali-450 GPU at 700 MHz, WLAN, a video decoder for up to 4K content, a LPDDR3 memory controller at 666 MHz, and a 2G/3G (UMTS/HSPA+) radio.

Although the MT6592 offers eight relatively high clocked CPU cores compared to other SoCs, its performance in day-to-day usage is a bit lower, as the Cortex-A7 cores offer slower performance per clock and only a few apps are able to make use of all 8 cores simultaneously. Modern dual-core (e.g., Apple A7) or quad-core (e.g., Cortex A15 or Snapdragon 800) SoCs can be clearly faster in everyday scenarios.

The integrated ARM Mali-450 MP4 GPU offers 4 graphics clusters that are clocked at a high 700 MHz. However, the performance of the GPU is somewhat below that of a Tegra 4 or Adreno 320. Also like the Nvidia rival, the Mali-450 lacks support for OpenGL ES 3.0.

Intel Core i5-1145G7

The Intel Core i5-1145G7 is a power efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation that was announced early 2021. It integrates four Willow Cove processor cores (8 threads thanks to HyperThreading). The base clock speed depends on the TDP settings and ranges from 1.1 GHz (12 Watt TDP) up to 2.6 GHz (28 Watt). The Boost is always specified at 4.4 GHz (one or two cores).

Another novelty is the integrated Xe graphics card 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).

Furthermore, 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. In addition to this, the i5 supports vPro for easy remote management.

The chip is produced on the improved 10nm SuperFin process at Intel that should be comparable to the 7nm process at TSMC (e.g. Ryzen 4000 series).
