Intel Core i7-8700K vs Intel Core i7-10875H

Intel Core i7-8700K

The Intel Core i7-8700K is a high-end desktop processor with six cores based on the Coffee Lake architecture and was announced in September 2017. The processor clocks at between 3.7 and 4.7 GHz and can execute up to twelve threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. The i7-8700K is comparatively easy to overclock thanks to the unlocked multiplier.

Performance

Due to the two additional cores, performance has increased by almost 50% compared to the Core i7-7700K when all cores are in use. Single-core performance has not improved since its Kaby Lake predecessor. As a high-end model, the i7-8700K is suitable for the most demanding applications and games.

Graphics

The integrated Intel UHD Graphics 630 iGPU is supposed to offer higher performance as its clock rate has been increased by 50 MHz. The build is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.

Power Consumption

Intel specifies the TDP with 95 watts. Therefore, well-dimensioned cooling systems should easily manage to deal with the created heat. We expect increased efficiency due to the higher performance.

Intel Core i7-10875H

The Intel Core i7-10875H is a high-end processor for laptops with eight cores based on the Comet Lake architecture (CML-H, 4th generation of Skylake). The processor clocks at between 2.3 and 5.1 GHz (4.3 with all 8 cores, 4.9 without Thermal Velocity boost) and can execute up to sixteen threads simultaneously thanks to Hyper-Threading. The processor is still manufactured in the old 14nm (14nm++) process. Compared to the predecessors, the Comet Lake-H series CPUs offer only increased clock rates.

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 i7-10875H supports the management features vPro, TXT and SIPP. 

Performance

The performance of the Core i7-10875H should be somewhere around the older Core i9-9880H. Thanks to the 8 cores and high Turbo speeds, even demanding applications should run very good on the CPU. However, long term performance is always depending on the laptop cooling system and system configuration.

Graphics

The integrated Intel UHD Graphics 630 iGPU is supposed to offer a similar performance as the UHD630 in the Core i7-9880H. As a  low-end solution it will only run current games smoothly at reduced details - if at all.

Power Consumption

Intel specifies the TDP with 45 watts and therefore the i7 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.
