Intel Core i5-10500H vs Intel Core i9-11900KB

Intel Core i5-10500H

The Intel Core i5-10500H is a fast processor for laptops with six cores based on the Comet Lake-H series (4th generation of Skylake architecture). The processor clocks at between 2.5 and 4.5 GHz and can execute up to twelve threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured on a 14nm (14nm++) process. 

The Comet Lake architecture is similar to Coffee Lake and offers the same features and is produced on 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.

Performance

The average 10500H in our database matches the AMD Ryzen 7 4700U, a noticeably less power-hungry processor, in multi-thread performance making the i5 a somewhat underwhelming option as far as H-class processors go.

Your mileage may vary depending on how competent the cooling solution of your system is, and how high the CPU power limits are.

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

This Core i5 series chip has a default TDP, also known as the long-term power limit, of 45 W. Laptop makers are free to reduce that value slightly, 35 W being the minimum Intel-recommended value, resulting in lower clock speed and lower performance. Either way, an active cooling solution will still be needed to dissipate the heat.

The i5-10500H is built with one of the old 14 nm Intel processes for low, as of mid 2023, energy efficiency.

Intel Core i9-11900KB

The Intel Core i9-11900KB is an Octa-Core-CPU that was used in the Intel Beast Canyon NUC. It is based on the Tiger-Lake-H45 series and was announced in the second quarter of 2021. The processor cores can clock from 3.3 to 5.3 GHz, all cores at once can reach up to 4.9 GHz. The CPU features 24 MB level 3 cache and DDR4-3200 memory. The integrated UHD graphics card is based on the Xe-architecture with 32 cores and clocks up to 1.45 GHz.

As with the slower Tiger Lake-H CPUs, the 11900KB has a partly integrated WiFi 6E and Thunderbolt 4 in the chip. Furthermore, the 11900KB supports 20 PCIe 4.0 lanes.

The TDP is rated at 65 Watt with 3.3. GHz base clock and can be configured to 55 Watt (cTDP-down).
