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) and supports faster DDR4-2933 RAM.

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. More information on Comet Lake and all the models and articles on it can be found here.

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

Performance

The average 10300H in our database matches AMD Ryzen 5 3550H in multi-thread performance. While not a poor result per se, it is indicative of an entry-level H-class CPU that is unlikely to meet the needs of hardcore gamers, professional videographers and similar clientele.

Graphics

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

The Core i5 has a default TDP (also known as the long-term power limit) of 45 W, a value that laptop manufacturers are free to reduce slightly, 35 W being the lower limit, resulting in lower clock speeds and lower performance. Either way, a high-performance cooling solution is a must for a CPU like this.

This Intel CPU is manufactured on a fairly old, as of early 2023, 14 nm Intel process for lower-than-average energy efficiency.
