Intel Core i7-10870H

Intel i7-10870H

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.

Architecture

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.

Performance

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.

Graphics

The Intel UHD Graphics 630 is an old acquaintance of ours; this 24 EU iGPU was used in many H-class Intel Core processors of previous years, like a Core i7-9750H.

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.

Power consumption

Core i7-10870H has a 45 W TDP (also known as the Power Limit 1). OEMs are allowed to reduce that value somewhat, the lower limit being 35 W, with clock speeds and thus performance taking a hit as a result. As far as short-term loads are concerned, the CPU will happily consume 70 or even 100 W when Boosting, making quality active cooling solution a must.

This 10th generation Intel chip is manufactured on an old, as of late 2022, 14 nm process for subpar energy efficiency.
