Intel Core i3-10110U vs Intel Core i3-1215U vs Intel Core i7-10710U

Intel Core i3-10110U

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, as of late 2021, its multi-thread benchmark scores nearly matching those of the AMD Ryzen 3 3250U and also the Core i3-8145U. While not a whole lot faster than Intel's more affordable Pentium Gold and Pentium Silver chips, the i3 will still let you run most apps with virtually no annoying slowdowns.

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

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 series chip has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop makers are allowed to change to anything between 10 W and 25 W with clock speeds and performance changing correspondingly. By going for the lowest value, it will be possible to build a passively cooled system around the SoC.

The i3-10110U is built with one of the old 14 nm Intel processees for low, as of early 2023, energy efficiency.

Intel Core i3-1215U

The Intel Core i3-1215U is a mid-range mobile CPU for thin and light laptops based on the Alder Lake architecture. It was announced in early 2022 and offers 2 performance cores (P-cores, Golden Cove architecture) and 4 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 8 supported threads when combined with the E-cores. The clock rate ranges from 1.2 to 4.4 GHz on the performance cluster and 0.9 to 3.3 GHz on the efficient cluster. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 10 MB L3-cache. Compared to the faster i5 and i7 models, the i3 does not include vPro features.

Performance

The average 1215U in our database is in the same league as the Ryzen 3 5300U and also the Core i7-1185G7, as far as multi-thread benchmark scores are concerned. This is decent enough of a result, as of late 2022. For an entry-level CPU, that is.

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

Features

The integrated memory controller supports various memory types up to DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. The Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficient cores for the best performance. For AI tasks, the CPU also integrates GNA 3.0 and DL Boost (via AVX2). Quick Sync in version 8 is the same as in the Rocket Lake CPUs and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC, and AV1 decode in hardware. The CPU only supports PCIe 4.0 (x8 for a GPU and two x4 for SSDs).

The integrated graphics card is based on the Xe-architecture and offers 64 of the 96 EUs (Execution Units) operating at up to 1.1 GHz.

The CPU is rated at 15 W base power (TDP, PL1) and 55 W max. Turbo power (PL2) and the whole SoC is manufactured in a 10nm process at Intel, which is known as Intel 7.

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.
