Intel Core i7-8565U vs Intel Core i7-10510U vs Intel Pentium Gold 6405U

Intel Core i7-8565U

► remove from comparison

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 i7-10510U

► remove from comparison Intel i7-10510U

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.

Intel Pentium Gold 6405U

► remove from comparison Intel Pentium Gold 6405U

The Intel Pentium Gold 6405U is a power efficient entry-level dual-core SoC for notebooks based on the Comet Lake (CML-U) generation and was announced in October 2019. Compared to the similar Whiskey Lake Pentium 5405U processors, the difference is the higher clock speed (+100 MHz) and support for faster memory. The processor cores are clocked at 2.4 GHz (no Turbo). Thanks to HyperThreading 4 threads can be used. More information on Comet Lake and all the models and articles on it can be found here.

Due to the 100 MHz higher clock speed, the Pentium Gold 6405U should be slightly faster than the old Pentium 5405U and therefore in the entry level of mobile processors. The missing Turbo and only two cores are definitely a downside and therefore the CPU is best used for simple tasks like browsing and office programs. Compared to the faster Core i3, i5 and i7 Comet Lake models, the Pentium does not support SSE (2).

The integrated graphics card is still the same as in the previous generations. It is called only Intel UHD Graphics but is still the same Intel UHD Graphics 610 like in the Pentium 5405U. Furthermore, the SoC integrates a VP9 and H.265 de- and encoder and an integrated dual channel LPDDR3-2133/DDR4-2400 memory controller (compared to DDR4-2666 in the faster Core i3).

The chip is still produced in the 14nm++ process as Whiskey Lake. The TDP (PL1) is specified at 15 Watts but can be lowered to 12.5 Watt although the CPU then only runs at 800 MHz.
