The Intel Core i5-10310Y is a extremely power efficient quad-core SoC for small laptops and tablets based on the Comet Lake (CML-Y) generation and was announced in August 2019. Compared to the similar Amber Lake processors (e.g. Core i7-8500Y), the only difference are two additional cores in the top models (except i3-10110Y). The processor cores are clocked between 1.1 and 4.1 GHz (all 4 cores 2.8 GHz max). Thanks to HyperThreading 8 threads can be used. Compared to the faster i7-10510Y, the level 3 cache is reduced to 6 MB and the clock rates are lower.
More information on Comet Lake and all the models and articles on it can be found here.
Performance
While we have not tested a single system built around the 10310Y as of August 2023, it's realistic to expect the chip to be about half as fast as the Core i5-10210U (Comet Lake, 4 cores, 8 threads, up to 4.2 GHz) in multi-thread workloads. Those 4 cores of the 10310Y are set to be very much constrained by the low TDP target leading to high DPC latencies and generally unresponsive system behaviour no matter the activity.
The integrated graphics adapter is still the same as in the previous generations. It should be still called Intel UHD Graphics 615 and clock from 300 - 1050 MHz in the i5. Furthermore, the SoC integrates a VP9 and H.265 de- and encoder.
The chip is now produced in the 14nm++ process (Amber Lake Y was 14nm+) but not 10nm like Ice Lake Y. The TDP is specified at 7 Watts but can be varied from 5.5 to 9 Watt from the manufacturer (cTDP up/down) resulting in different performance (especially Turbo durations).
Intel Core i3-1125G4

The Intel Core i3-1125G4 is a 28 W quad-core SoC for laptops and Ultrabooks of the Tiger Lake family (UP3) that was introduced in September 2020. It integrates four Willow Cove processor cores (8 threads thanks to Hyper-Threading). Each core can clock from 2 GHz (guaranteed base speed @ 28 W) to 3.7 GHz (single-core boost). All cores at once can clock at up to 3.3 GHz. The faster Core i7 models offer more Level 3 cache (12 versus 8 MB in the i5) and higher clocked cores.
Another novelty is the integrated Xe GPU based on the completely new Gen 12 architecture. In the i3-1125G4 Intel names the GPU UHD Graphics and offers only 48 of the 96 EUs clocked at 400 - 1250 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.
Performance
While we have not tested a single laptop built around the 1125G4 as of October 2023, we expect the chip's multi-thread performance to be 10% to 20% lower than that of the Core i5-1135G7 (4 cores, 8 threads, somewhat higher clock speeds).
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 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 little too high to allow for passively cooled designs.
The i3-1125G4 is manufactured on Intel's third-gen 10 nm process marketed as SuperFin for average, as of early 2023, energy efficiency.
