Intel Core i7-8565U vs Intel Core i3-10110U

Intel Core i7-8565U

The Intel Core i7-8565U is a power efficient quad-core SoC for notebooks and Ultrabooks based on the Whiskey Lake generation that was announced in August 2018 (IFA). Compared to the similar named Kaby Lake-R processors (e.g. Core i7-8550U), the Whiskey Lake CPUs are now produced in a further improved 14nm process (14nm++) and offer higher clock speeds. The architecture and features are the same. The i7-8565U offers e.g. high Turbo clock speeds of 4,6 GHz (versus 4 GHz of the i7-8550U) for a single core and 4.1 GHz (versus 3.7 GHz) of all cores (4.1 GHz for 2 cores). The integrated GPU is still named Intel UHD Graphics 620 and the dual-channel memory controller still supports the same RAM speeds as Kaby-Lake-R (DDR4-2400 / LPDDR3-2133). Compared to the slower Core i5-8265U and i3-8145U, the i7 supports Thermal Velocity Boost.

The Whiskey Lake SoCs are used with a new PCH produced in 14nm that supports USB 3.1 Gen 2 (10 Gbps) and CNVi WiFi/BT parts.

Architecture

Intel basically uses the same microarchitecture compared to Skylake and Kaby Lake, so the per-MHz performance does not differ. That means Whiskey Lake is a Kaby Lake chip manufactured in the improved 14nm++ process.

Performance

The performance of the i7-8565U depends on the cooling solution of the laptop and the defined TDP limits for short and long term performance. We already saw big differences for Kaby Lake-R (e.g., i7-8550U benchmarks), especially for long term (sustained) performance. Therefore, it will be interesting to see how the additional Turbo  clock speed can be made use of. It looks like Intel is promoting the i7 to be 3 - 11% faster than the previous i7-8550U, with Cinebench R15 Multi reaching 5% gains.

Graphics

The integrated Intel UHD Graphics 620 (Intel Gen 9.5) is untouched from the 8th Gen Kaby Lake chips. With fast dual-channel memory, it can reach the performance of a dedicated GeForce 920M.

Contrary to Skylake, Kaby Lake and Whiskey Lake now also supports H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors announced in January should also support HDCP 2.2.

Power Consumption

The chip is manufactured in a further improved 14nm process with FinFET transistors (14nm++), the same as the 8th Gen Coffee Lake processors. Intel still specifies the TDP with 15 Watts, which is typical for ULV chips. Depending on the usage scenario, the TDP can vary between 7.5 (cTDP Down) and 25 Watts.

Intel Core i3-10110U

The Intel Core i3-10110U is a dual-core SoC of the Comet Lake family. The i3 is designed for use in ultraportable laptops of the more affordable flavor as well as mini-PCs. It was announced in August 2019. Just like the other Comet Lake processors, this Core i3 features several advantages over the outgoing Whiskey Lake family including support for faster memory (up to LPDDR4-2933).

Core i3-10110U runs at 2.1 GHz to 4.1 GHz (only 3.7 GHz are reachable when under multi-thread load). Hyper-Threading support is enabled for 4 processing threads in total.

Performance

The average 10110U in our database shapes up to be a decent entry-level CPU, as of late 2021, its multi-thread benchmark scores nearly matching those of the AMD Ryzen 3 3250U and also the Core i3-8145U. While not a whole lot faster than Intel's more affordable Pentium Gold and Pentium Silver chips, the i3 will still let you run most apps with virtually no annoying slowdowns.

Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.

Graphics

The Intel UHD Graphics 620 runs at up to 1,000 MHz. What makes this specific iGPU peculiar is that it only has 23 Execution Units at its disposal, not the 24 EUs typical for a UHD Graphics 620. Otherwise, it's the usual affair with 4K monitor support (up to three displays at the same time) and a hardware video decoder that's friends with VP9, AVC, HEVC but not the newer AV1 video codec.

Power consumption

This Core i3 series chip has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop makers are allowed to change to anything between 10 W and 25 W with clock speeds and performance changing correspondingly. By going for the lowest value, it will be possible to build a passively cooled system around the SoC.

The i3-10110U is built with one of the old 14 nm Intel processees for low, as of early 2023, energy efficiency.
