Intel 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.

Thanks to the high clock speeds, the processor performance of the i5-10210U is very good for its class. It should outperform the Whiskey Lake i5-8365U slightly and also Ice Lake i5 processors if the cooling and TDP settings are not limiting.

The integrated graphics card 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.

The chip is still produced in the 14nm++ process as Whiskey Lake. The TDP (PL1) is specified at 15 Watts but can be varied from 10 to 25 Watt from the manufacturer (cTDP up/down) resulting in different performance (especially Turbo durations). To provide the full performance, Intel proposes a short power peak of 82 W (PL4) for the i5 (90W even for the 6-core i7) and 11 W more than Whiskey Lake.
