Intel Core i7-10710U vs AMD Ryzen 7 7730U vs Intel Core i7-10510U

Intel Core i7-10710U

The Intel Core i7-10710U is a power efficient hexa-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 i5-8665U), the only difference is support for higher memory speeds (DDR4-2666 vs 2400) and two additional cores in the top model. The processor cores are clocked between 1.1 and 4.7 GHz (all 6 cores 3.9 GHz max). Thanks to HyperThreading 12 threads can be used. More information on Comet Lake and all the models and articles on it can be found here.

Thanks to the two additional cores and the high clock rates, the processor performance of the i7-10710U is very good for its class. It should outperform the top Whiskey Lake and also Ice Lake processors if the cooling and TDP settings are not limiting.

The integrated graphics card 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 / LPDDR4x 2933 / LPDDR3-2133 memory controller.

The chip is still produced on the 14nm++ process as Whiskey Lake. The TDP (PL1) is specified at 15 Watts but can be varied from 12.5 to 25 Watt from the manufacturer (cTDP up/down) resulting in different performance (especially Turbo durations). To provide the full performance, Intel proposes a short power peak of 90 W (PL4) for the i7 and therefore 8 W more than the quad-core CML-U CPUs and a whopping 19 W more than Whiskey Lake. Therefore, some slim laptops with 15W CML-U CPUs wont offer the i7 as they cant provide enough power and cooling to get full performance out of the 6 cores.

AMD Ryzen 7 7730U

The AMD Ryzen 7 7730U is a processor for thin and light laptops based on the Cezanne generation. It is part of the second "Barcelo" refresh in early 2023 and offers the same specifications as the old Ryzen 7 5825U. The CPU integrates all eight cores based on the Zen 3 microarchitecture clocked at 2 (guaranteed base clock) to 4.5 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured in 7nm at TSMC.

The Zen 3 microarchitecture offers a significantly higher IPC (instructions per clock) compared to Zen 2 but stays behind the current Zen 4 based CPUs (e.g. 7040HS series).

Performance

The average 7730U in our database is in the same league as the Ryzen 7 5825U, Ryzen 7 6800U, Ryzen 7 PRO 6850U and also the Core i7-1360P, as far as multi-thread benchmark scores are concerned.

Thanks to its decent cooling solution and a long-term CPU power limit of 30 W, the ThinkPad E14 G5-21JSS05C00 is among the fastest laptops built around the 7730U that we know of. It can be almost 40% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 8 GPU with 8 CUs at up to 2000 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB level 3 cache (up from 8 MB at the 4800U) can be found on the chip.

The TDP of the APU is specified at 15 Watt (the 5825U was specified at 10 - 25W). 

Intel Core 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 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.
