Intel Core i5-10310U vs Intel Core i5-1035G7

Intel Core i5-10310U

The Intel Core i5-10310U 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 i5-8665U), the only difference is support for higher memory speeds (DDR4-2666 vs 2400) and two additional cores in the top model (not in this i5). The processor cores are clocked between 1.7 and 4.4 GHz (unverified). Thanks to HyperThreading 8 threads can be used. Compared to the faster i5-10510U, the level 3 cache was reduced from 8 to 6 MB. More information on Comet Lake and all the models and articles on it can be found here. The CPU supports the professional management features under the vPro umbrella.

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 - 1100 MHz in the i5. 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.

Performance

The average 10310U in our database is not really any different than other quad-core laptop CPUs running at similar clock speeds, such as the Ryzen 5 3450U or the Core i5-1035G4.

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

Power consumption

This Core i5 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 with clock speeds and performance changing correspondingly. Perhaps more importantly, short-term power consumption can be as high as 80 W or even 90 W as far as 10th gen Comet Lake U chips are concerned, making passively cooled designs unlikely.

This Intel processor is manufactured on a fairly old, as of late 2022, 14 nm Intel process for subpar energy efficiency.

Intel Core i5-1035G7

The Intel Core i5-1035G7 is a power efficient quad-core SoC for laptops and Ultrabooks based on the Ice -Lake-U generation that was announced in Mai 2019 (Computex). It integrates four Sunnycove processor cores (8 threads thanks to HyperThreading) clocked at 1.2 (base) - 3.7 (single core Turbo) GHz. 2 cores can reach 3.6 GHz and all four 3.3 GHz using Turbo Boost. According to Intel the Sunnycove cores achieve 18% more IPCs (Instructions per Clock). The Core i5-1035G7 is the second fastest Ice Lake-U chip at the time of announcement in 2019.

The biggest improvement for Ice-Lake is the integrated Gen 11 graphics adapter called Iris Plus Graphics. The Core i7-1065G7 integrates the biggest G7 variant with 64 CUs clocked at 300 - 1100 MHz. The Iris Plus G7 should be twice as fast as the predecessors and best the AMD Vega 10 GPU in current Ryzen APUs.

Other improvements for Ice Lake are the AI hardware acceleration and the partial integration of Thunderbolt and Wifi 6 in the chip. The integrated DDR4 memory controller supports modules with up to 3200 MHz (and LPDDDR4-3733).

Performance

The average 1035G7 in our database is in the same league as the Ryzen 3 4300U and the Core i5-10210U, as far as multi-thread benchmark scores are concerned. Which isn't bad at all as of late 2021. The Core i5-1035G4 and the Core i5-1035G1 are two other chips that nearly match the 1035G7 in multi-thread performance.

Thanks to its decent cooling solution and a long-term CPU power limit of 22 W, the Surface Laptop 3 13 is among the fastest laptops built around the 1035G7 that we know of. It can be at least 30% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Core i5 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 12 W and 25 W if required with clock speeds and performance changing accordingly. Those values are a little too high to allow for passively cooled designs.

The processor is built with Intel's second-gen 10 nm process for decent, as of late 2022, energy efficiency.
