Intel Core i7-10875H vs Intel Core i7-10750H

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.

Intel Core i7-10750H

The Intel Core i7-10750H is a high-end 45 W processor designed for large laptops. The Comet Lake-H CPU was launched in mid-2020 with six cores commanding twelve threads in total thanks to the Hyper-Threading support running at 2.6 GHz to 5 GHz (single-core Boost). The all-core Boost frequency is likely to be 4.3 GHz. There appears to be no significant difference between an i7-10750H and the i7-9750H except for the higher Boost frequency of the former.

Architecture

Just like the Coffee Lake, Whiskey Lake, and Kaby Lake families, the Comet Lake is a yet another revision of the dated Skylake architecture for similar performance-per-MHz between the five. There are few differences between Comet Lake and Coffee Lake processors as far as the features and the capabilities go. Core i7-10750H is manufactured on the third-gen 14 nm Intel process that is no longer cutting-edge as AMD’s Ryzen 4000 processors are manufactured on the 7 nm TSMC process.

Core i7-10750H is compatible with dual-channel DDR4-2933 RAM. It has support for PCI-Express 3.0 and Thunderbolt 3 but not the professional features (vPro, TXT, SIPP) unlike the Core i7-10850H. Both the CPU cores and the iGPU have access to 12 MB of L3 cache. The SoC gets soldered straight on to the motherboard (BGA1440 socket) and is extremely hard to replace.

Performance

The cooling system performance as well as the TDP settings have a huge impact on the Boost sustainability that directly influences the CPU performance. Our independent testing puts the i7 close to Core i7-8559U and the Ryzen 7 3700X in single-core benchmarks, and multi-core testing reveals the CPU to be similar to the Ryzen 5 5500U and the Ryzen 5 5600H. The Core i7 is a very decent CPU for laptops released in 2020 and 2021 and it is good for any task including gaming and content creation.

Graphics

The Intel UHD Graphics 630 iGPU is not all that different from the UHD 630 found in the Core i7-9750H and the Core i7-8750H as well as the HD 630 found in the Core i7-7820HQ. In the case of Core i7-10750H, the 24 EU iGPU is clocked at 350 MHz to 1,150 MHz. It supports up to 3 monitors with resolutions of up to 4096 by 2304 and the built-in video decoder can handle AVC, HEVC, VP9 video streams but not the newer AV1 codec. This is not a gaming GPU as it is not fast enough to handle most games released in 2020. FRAPS reports 17 fps when running Escape from Tarkov at 720p (low quality preset), to give you an example.

Power Consumption

The energy efficiency is not great as the 14 nm manufacturing process is very old by now. While the default TDP for the i7 CPU equals 45 watts, the actual consumption when under load will be significantly higher than this. Core i7-10750H is a good choice for a large laptop with a high-performance cooling system. OEMs can choose to set the TDP to 35 watts instead of the 45 watts for lighter and leaner designs but the lower TDP will cause the base frequency as well as the Boost frequency to go down.
