Intel Core i5-10300H

The Intel Core i5-10300H is a fast processor for laptops with four cores based on the Comet Lake-H series (4th generation of Skylake architecture). The processor clocks at between 2.5 and 4.5 GHz (up to 4.2 with 4 cores) and can execute up to eight threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in 14nm (14nm++) process. Compared to the predecessor, the Core i5-9300H from 2019, the 10300H is clocked slightly higher (+100 MHz Base, +400 MHz Boost).

The Comet Lake architecture is similar to Coffee Lake and offers the same features and is produced in the same 14nm process. Other than the improved clock rates, the memory controller now also supports faster DDR4-2933 RAM.

The Core i5-10300H supports no vPro, TXT or SIPP. These business features are available in the faster (and later released) Core i5-10400H (2.6 – 4.6 GHz).


A well cooled Intel Core i5-10300H can reach the average performance of an old Core i7-8750H (6 cores, but lower clock speeds). Multi-threaded tests that can use all cores however are clearly slower. Compared to the older Core i5-9300H, the 10300H is clearly faster thanks to the higher clock speed of the CPU cores. In general, the CPU is well suited for multi-tasking and demanding workloads. Very fast mobile graphics cards however will be limited by the Core i5-10300H.


The integrated Intel UHD Graphics 630 iGPU is supposed to offer a similar performance as the UHD630 in the Core i5-9300H. As a  low-end solution it will probably only run current games smoothly at reduced details – if at all.

Power Consumption

Intel specifies the TDP with 45 watts and therefore the i5 is only suited for big laptops with good cooling solutions. Using cTDP-down, the CPU can also be configured to 35 Watt resulting in a reduced performance.
