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 near those of the Ryzen 7 2700U and the Core i5-8259U. While not as impressive as the hexa-core Core i7-10710U, the 10510U will make most customers happy, making for short load times and generally pain-free experience.
Thanks to its decent cooling solution and a long-term CPU power limit of 45 W, the Modern 15 A10RB is among the fastest laptops powered by the 10510U that we know of. It can be more than twice as fast in CPU-bound workloads as the slowest system featuring the same chip in our database, as of August 2023.
Power consumption
This Core i7 series chip has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop makers are free to change to anything between 10 W and 25 W resulting in corresponding performance and clock speed changes. By going for the lowest value, it is possible to build passively cooled tablets, laptops, mini-PCs around the i7. Please note that Comet Lake-U chips can briefly consume up to 90 W when under extreme loads.
Last but not the least, the i7-10510U is built with one of the old 14 nm Intel processes for lower-than-average, as of late 2022, energy efficiency.
The AMD Ryzen 7 4700U is a processor for thin and light laptops based on the Renoir architecture. The 4700U integrates all eight cores based on the Zen 2 microarchitecture. They are clocked at 2 (guaranteed base clock) to 4.1 GHz (Turbo). There is no support for the thread-doubling SMT tech. The chip is manufactured on the modern 7 nm TSMC process and partly thanks to it AMD advertises a 2x improved performance per Watt for the Renoir chips. Compared to the faster R7 4800U, the 4700U offers slightly lower clock speeds and no support for SMT / Hyperthreading.
In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 7 integrated graphics card with 7 CUs and up to 1600 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 8 MB level 3 cache can be found on the chip. See our hub page on the Renoir Processors for more information.
Performance
The average 4700U in our database proves to be a rather competent little processor. It trades blows with the much more power-hungry Intel Core i7-10750H, as far as multi-thread benchmark scores are concerned. While it fails to get far enough away from the more affordable Ryzen 5 4600U, this Ryzen 7 is still a good CPU for most tasks.
Your mileage may vary depending on how competent the cooling solution of your laptop is and how high the CPU power limits are.
Power consumption
The Ryzen 7 4700U is a 15 W chip. However, laptop makers are allowed to change that value to anything between 10 W and 25 W, with clock speeds and long-term performance changing accordingly as a result. By going for the lowest value, it is possible to build a passively cooled system around the APU.
The fairly modern 7 nm TSMC process this Ryzen is manufactured on makes for above average, as of mid 2022, energy efficiency.
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.
