Intel Xeon W-10855M vs Intel Core i7-10750H vs Intel Core i7-10870H
Intel Xeon W-10855M► remove from comparison
The Intel Xeon W-10855M 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 2.8 and 4.8 GHz (probably 4.4 GHz with 6 cores) and can execute up to twelve threads simultaneously thanks to Hyper-Threading. The processor is still manufactured in the old 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 Intel Xeon W-10855M supports the management features vPro, TXT and SIPP and is the professional version of the Core i7-10850H with slightly higher clock speeds (+100 MHz base speed).
The performance of the Xeon W-10855M should be similar to the old top model Core i7-8950H (6 cores, 2.9 - 4.8 GHz). Thanks to the 6 cores and high Turbo speeds, even demanding applications should run fine on the CPU. However, long term performance is always depending on the laptop cooling system and system configuration.
The integrated Intel UHD Graphics P630 iGPU is supposed to offer a similar performance as the UHD630 in the Core i7-9750H. 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.
Intel Core i7-10750H► remove from comparison
The Intel Core i7-10750H is a fast 45 W processor designed for use in larger, beefier laptops. The Comet Lake-H family CPU was launched in mid-2020. It features six cores (twelve threads) running at 2.6 GHz Boosting up to 5 GHz (single-core Boost). The likely all-core Boost frequency is 4.3 GHz. Most of the specs are the same as the 10750H’s direct predecessor, the i7-9750H. The newer model has two advantages over its predecessor in that its Boost frequency is higher and the memory controller can now officially host memory clocked at 2,933 MHz, an upgrade over the 2,666 MHz limitation of the outgoing model.
Comet Lake is a yet another revision of the dated Skylake architecture (not unlike the previous Coffee Lake, Whiskey Lake, Kaby Lake families) for similar feature set and performance-per-MHz figures. Core i7-10750H is manufactured on the third-gen 14 nm Intel process that is undeniably inferior to TSMC's 7 nm process, the one AMD’s Ryzen 4000 series laptop-grade processors are manufactured on.
The hexa-core CPU is compatible with up to 128 GB of dual-channel DDR4-2933 RAM and has support for PCI-Express 3.0 and Thunderbolt 3 but not the professional features (vPro, TXT, SIPP) as found in the case of Core i7-10850H.
Both the CPU cores and the iGPU have access to 12 MB of L3 cache. 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.
Intel 10750H gets soldered permanently on to the motherboard (BGA1440 socket interface) and is thus pretty much impossible to replace.
The average 10750H in our database is as fast as the Core i7-8559U and Ryzen 7 3700X in single-core benchmarks while multi-core testing reveals the CPU to be similar to the Ryzen 5 5500U and Ryzen 5 5600H. As of mid-2021, the i7 is fast enough for any task, gaming included. Your mileage may vary depending on how high the Power Limits are and how competent the cooling solution of a laptop is.
Intel UHD Graphics 630 supports up to 3 monitors with resolutions of up to [email protected] and the built-in video decoder can handle AVC, HEVC, VP9 and other popular video codecs (AV1 is not supported here). This is not a gaming GPU as it is not fast enough to handle most AAA titles released in 2020. At 720p resolution, Escape from Tarkov runs at just 17 fps (low quality preset), to give you an example. As the iGPU has no VRAM of its own, it is paramount that fast system RAM is used.
Energy efficiency is not great here as the 14 nm manufacturing process is very old by now. While the default TDP value (also known as the long-term Power Limit) of the i7 sits at 45 W, the actual consumption when under heavy load will be significantly higher than this.
Core i7-10750H is designed for use in chunky, hard to carry around laptops, and a high-performance cooling system is a must. OEMs are free to set the TDP to 35 watts instead of 45 watts for leaner designs but the base as well as the Boost clock speeds would take a hit as a result.
Intel Core i7-10870H► remove from comparison
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-thread benchmarks, coming really close to AMD Ryzen 5 5600H and Intel Core i9-9980HK. It is thus absolutely capable of handling any task that requires 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.
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 Power Limit 1) that can be set to as low as 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.
