Intel Core i7-10875H vs Intel Core i7-10870H vs Intel Core i5-10500H
Intel Core i7-10875H► remove from comparison
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.
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.
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.
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.

The Intel Core i7-10870H is a higher-end, octa-core processor of the Comet Lake product family. The Hyper-Threading-enabled processor was unveiled in 2020. It is designed for use in large gaming laptops and DTRs; its CPU cores run at 2.2 GHz (base clock speed) to 5 GHz (max. Boost frequency). The all-core Boost frequency sits at 4.2 GHz.
Core i7-10870H is slightly inferior to Core i7-10875H in that the former has a 100 MHz lower base clock speed, 100 MHz lower Boost clock speed and no support for Intel's proprietary security features: vPro, TXT, SIPP.
Last but not the least, this H-class processor features the 24 EU UHD Graphics 630 iGPU.
Comet Lake is a yet another revision of the dated Skylake architecture (much like the previous Coffee Lake, Whiskey Lake, Kaby Lake product families) for similar feature set and performance-per-MHz figures.
Still, 10th Generation Core processors have their advantages. The upgraded memory controller is one such advantage; it can officially host memory clocked at 2,933 MHz, an upgrade over the 2,666 MHz limitation of the outgoing Coffee Lake product family. Intel recommends using no more than 128 GB, for reference.
Core i7-10870H is manufactured on Intel's third-gen 14 nm process. The octa-core CPU is compatible with Thunderbolt 3; it has sixteen PCI-Express 3.0 lanes for connecting discrete graphics cards, SSDs and other devices. Four PCI-Express 3.0 lanes allow for read/write rates of up to 3.9 GB/s provided a suitably fast NVMe SSD is used.
Please note this isn't a user-replaceable CPU. It gets soldered permanently on to the motherboard (BGA1440 socket interface) and is thus pretty much impossible to replace.
The i7 scores well in multi-core benchmarks; it is noticeably faster than the outgoing Core i9-9880H and is thus absolutely capable of handling any tasks that require significant processing muscle. Your mileage may vary depending on how high the Power Limits are and how competent the cooling solution of a laptop is.
While this is a good laptop-grade processor, AMD's 7 nm offerings (we are looking at you, Ryzen 7 4800H) are even better in that they deliver higher performance while consuming less energy.
In the case of 10870H, the UHD Graphics runs at 350 MHz to 1,200 MHz. It will let you use up to 3 displays simultaneously. The highest resolution supported here is 4K (4096 by 2304 pixels). This graphics adapter will happily hardware-decode VP9, AVC, HEVC, MPEG-2 and other popular video codecs; the latest AV1 codec did not make the list.
UHD Graphics 630 was not made for gaming; it is not fast enough to handle most triple-A titles of 2019 and 2020, even if you set the resolution to 1024 x 768 and select the lowest quality preset possible.
Core i7-10870H has a 45 W TDP (also known as the long-term Power Limit) that can be set to 35 W if an OEM so desires. Clock speeds and thus performance would take a hit as a result.
The old 14 nm process makes for rather poor energy efficiency. The CPU will happily consume 70 or even 100 W when Boosting. Quality cooling solution is a must.
Intel Core i5-10500H► remove from comparison
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.
The average 10500H in our database matches AMD Ryzen 7 4700U, a much less power-hungry processor, in multi-thread performance, making it an underwhelming option as far as H-class processors go. Still, this Core i5 won't look out of place in a budget gaming laptop.
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.
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.
