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.
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.
The Intel Core i7-10510U is a power efficient quad-core SoC for notebooks based on the Comet Lake (CML-U) generation and was announced in August 2019. Compared to the similar Whiskey Lake processors (e.g.& Core i7-8665U), the only difference is support for higher memory speeds (DDR4-2666, LPDDR4-2933) and two additional cores in the top model (not in this i7-10510U). The processor cores are clocked between 1.8 and 4.9 GHz (all 4 cores 4.3 GHz max). Thanks to HyperThreading 8 threads can be used. More information on Comet Lake and all the models and articles on it can be found here.
The integrated graphics adapter however is still the same as in the previous generations. It should be still called Intel HD Graphics 620 and clock from 300 - 1150 MHz in the i7. Furthermore, the SoC integrates a VP9 and H.265 de- and encoder and an integrated dual channel DDR4-2666 / LPDDR4-2933 memory controller.
Performance
The average 10510U in our database proves to be an OK mid-range option, its multi-thread benchmark scores hovering close to those of AMD Ryzen 7 2700U and Intel Core i5-8259U. While not as impressive as the hexa-core Core i7-10710U, the Core i7 will make most customers happy, providing for short load times and generally pain-free experience.
Power consumption
This Core i7 has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop manufacturers are free to change to anything between 10 W and 25 W resulting in corresponding performance and clock speed changes. Choosing the lowest value possible will allow for passively cooled tablets, laptops, mini-PCs.
The quad-core Intel CPU is built with a fairly old, as of early 2023, 14 nm Intel process for lower-than-average energy efficiency.
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, its multi-thread benchmark scores nearly matching those of AMD Ryzen 3 3250U and Intel Core i3-8145U. While not a whole lot faster than Intel's more affordable Pentium Gold and Pentium Silver processors, the i3 will still happily run most apps with virtually no annoying slowdowns.
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 has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop manufacturers are allowed to change to anything between 10 W and 25 W with clock speeds and performance changing correspondingly. Choosing the lowest value possible will allow for passively cooled designs.
The CPU is built with an old, as of early 2023, 14 nm Intel process for subpar energy efficiency.
