Intel Core i5-10310U

The Intel Core i5-10310U is a power efficient quad-core SoC for notebooks based on the Comet Lake (CML-U) generation and was announced in August 2019. Compared to the similar Whiskey Lake processors (e.g. Core i5-8665U), the only difference is support for higher memory speeds (DDR4-2666 vs 2400) and two additional cores in the top model (not in this i5). The processor cores are clocked between 1.7 and 4.4 GHz (unverified). Thanks to HyperThreading 8 threads can be used. Compared to the faster i5-10510U, the level 3 cache was reduced from 8 to 6 MB. More information on Comet Lake and all the models and articles on it can be found here. The CPU supports the professional management features under the vPro umbrella.

The integrated graphics adapter however is still the same as in the previous generations. It should be still called Intel HD Graphics 620 and clock from 300 - 1100 MHz in the i5. Furthermore, the SoC integrates a VP9 and H.265 de- and encoder and an integrated dual channel DDR4-2666 / LPDDR4x 2933 / LPDDR3-2133 memory controller.

Performance

The average 10310U in our database is not really any different than other quad-core laptop CPUs running at similar clock speeds, such as the Ryzen 5 3450U or the Core i5-1035G4.

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 has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop manufacturers are free to change to anything between 10 W and 25 W with clock speeds and performance changing correspondingly. Perhaps more importantly, short-term power consumption can be as high as 80 W or even 90 W as far as 10th gen Comet Lake U chips are concerned, making passively cooled designs unlikely.

This Intel processor is manufactured on a fairly old, as of late 2022, 14 nm Intel process for subpar energy efficiency.
