Intel Core i5-10400H vs Intel Core i5-10200H vs Intel Core i7-10850H

Intel Core i5-10400H

The Intel Core i5-10400H 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 2.6 and 4.6 GHz (up to 4.4 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. 

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 i5-10400H supports the management features vPro, TXT and SIPP. 

Performance

The performance should be slightly better than the old Core i7-8809G (Quad-Core 3.1 - 4.2) which was the fastest mobile quad core by Intel.

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

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.

Intel Core i5-10200H

The Intel Core i5-10200H is a fast quad-core processor for laptops with four cores based on the Comet Lake-H series (4th generation of Skylake architecture). The processor clocks at between 2.4 and 4.1 GHz  and can execute up to eight threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured on 14nm (14nm++) process.

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 i5-10200H 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).

Performance

The performance is only minimal better than the Core i5-9300H thanks to the support for faster DDR4-2933 RAM. This means, the CPU is well suited for demanding tasks, although the faster versions offer a significantly higher Turbo Boost clock speed for faster single core execution. 

Power consumption

This 10th gen Comet Lake processor has a default TDP (also known as the long-term power limit) of 45 W, a value that laptop manufacturers are allowed to reduce somewhat, 35 W being the lower limit. Doing so will result in lower clock speeds and lower performance. Either way, this CPU is too power-hungry to be used as the base of a passively cooled laptop.

Intel Core i5-10200H is built with an old, as of late 2022, 14 nm Intel process for subpar energy efficiency.

Intel Core i7-10850H

The Intel Core i7-10850H is a high-end processor for laptops with six cores based on the Comet Lake architecture (CML-H, 4th generation of Skylake). The processor clocks at between 2.7 and 5.1 GHz (with Thermal Velocity Boost and Turbo Boost 3.0). Using only Turbo Boost 3.0 (when the temperatures don't allow the the Thermal Velocity Boost) a single core can reach 4.9 GHz. All six cores can reach 4.4 GHz. The processor is still manufactured on the old 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.

The Core i7-10850H supports the management features vPro, TXT and SIPP.

Performance

The average 10850H in our database proves to be a somewhat disappointing CPU, only matching the Core i5-10500H and the Ryzen 5 5500U in multi-thread performance. While the Core i7 will have no issue running any app or any game you can install in 2021, there are better options out there both in terms of sheer power and in terms of power efficiency.

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

Graphics

The integrated Intel UHD Graphics 630 iGPU is supposed to offer a similar performance as the UHD 630 in the Core i7-9750H. As a low-end solution it will only run current games smoothly at reduced details - if at all.

Power consumption

This Core i7 series chip has a default TDP, also known as the long-term power limit, of 45 W, a value that laptop makers are free to reduce somewhat (with 35 W being the minimum Intel-recommended value) resulting in lower clock speeds and lower performance. Either way, the CPU is way too power-hungry to be the heart of a passively cooled mini-PC, laptop, tablet.

The i7-10850H is manufactured on one of the old 14 nm Intel processes leading to subpar, as of early 2023, energy efficiency.
