Intel Core i7-10610U vs Intel Core i3-1220P vs Intel Core i7-10810U

Intel Core i7-10610U

The Intel Core i7-10610U 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 vs 2400) and two additional cores in the top model (not in this i7-10610U). The processor cores are clocked between 1.8 and 4.9 GHz (unverified). Thanks to Hyper-Threading 8 threads can be used. More information on Comet Lake and all the models and articles on it can be found here.

Compared to the similar Core i7-10510U, the 10610U supports vPro.

The integrated graphics adapter however is still the same as in the previous generations. It should be still called Intel UHD 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.

Performance

The average 10610U in our database is in the same league as the Core i5-1035G1 and also the Core i5-8257U, as far as multi-thread benchmark scores are concerned.

Thanks to its decent cooling solution and a long-term power limit of 25 W, the HP ZBook Firefly 14 G7 is among the fastest laptops built around the 10610U that we know of. It can be about 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 i7 has a default TDP of 15 W (also known as the long-term power limit). Laptop manufacturers are free to change that value to anything between 10 W and 25 W, with clock speeds and performance changing accordingly. Perhaps more importantly, short-term power consumption of 10th gen Comet Lake U processors can be as high as 80 W or even 90 W, making passively cooled designs rather unlikely to appear.

Core i7-10610U is manufactured on an old, as of late 2022, 14 nm Intel process for subpar energy efficiency.

Intel Core i3-1220P

The Intel Core i3-1220P is a lower mid-range Alder Lake family SoC designed for use in ultra-light, ultra-thin laptops of the more affordable flavour. It was announced in early 2022 and it has 2 performance cores as opposed to the 6 cores of the top-of-the-line i7-1280P (P-cores, Golden Cove architecture) mated to 8 efficient cores (E-cores, Gracemont architecture). The i3's P-cores are Hyper-Threading-enabled for a total of 12 threads when combined with its E-cores. The clock speeds range from 1.5 GHz to 4.4 GHz for the performance cluster and 1.1 GHz to 3.3 GHz for the efficient cluster. The shortcomings of this processor as compared with the faster Core i5-1240P are many, including the significantly slower iGPU, lower CPU core count, lower clock speeds, complete lack of the vPro features.

Architecture

The i3 is a continuation of Intel's efforts to use the ARM-developed big.LITTLE technology for its own benefit. A single "little" Alder Lake core is supposed to be as fast as a Skylake core (as found in the venerable Core i7-6700HQ among other options) which is six years old at this point. All of Core i3-1220P's CPU cores enjoy access to 12 MB of L3 cache. The integrated memory controller supports various memory types up to LPDDR5-5200, DDR5-4800, LPDDR4x-4267 or DDR4-3200; Intel suggests using no more than 64 GB of RAM, for reference. Just like the other 12th Gen Intel Core processors, this Core i3 comes with the Thread Director which is a new functionality designed to help Windows 11 decide which cores to use for what workload for best performance and efficiency possible. Hardware acceleration of AI algorithms is supported via GNA 3.0 and DL Boost (via AVX2). PCI-Express 5.0 support has not found its way into Alder Lake P processors, so users will have to be content with PCI-Express 4.0 for the time being. Four PCI-Express 4 lanes allow for a read/write rate of up to 7.9 GB/s, provided a suitably fast NVMe SSD is used.

Please note that this is not a user-replaceable CPU. It gets soldered permanently on to the motherboard (FCBGA1744 socket interface).

Performance

While we have not tested a single system built around the 1220P as of October 2023, we have tested a laptop featuring the i5-1240U, a chip with nearly the same specs (2 P-cores mated to 8 E-cores, all running at the same clock speeds as what the 1220P has). Based on that, we expect the 1220P to be just slightly ahead of the Core i5-11400H, the Core i7-1265U and also the Ryzen 5 5600U, as far as multi-thread benchmark scores are concerned. 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 built-in graphics adapter in the form of the 64 EU UHD Graphics running at up to 1.1 GHz is a slightly downgraded 80 EU Iris Xe. The latter can be found in many Alder Lake-P and Tiger Lake-UP3 processors, like a Core i5-1250P or a Core i5-1145G7, respectively. Despite the lower EU cluster count, this is still a fairly capable iGPU, loaded with modern features such as the AV1 video decoding capability and SUHD 4320p monitor support. The UHD Graphics will happily drive up to 4 monitors simultaneously, provided the laptop has the outputs required. Its gaming performance is unlikely to please the crowds, though, as it will be good for resolutions no higher than 1600x900 and Low settings only in most titles trleased in 2021 and 2022. Your mileage may vary depending on how high the Power Limits are and how capable the cooling solution of a laptop is. Fast RAM is a prerequisite for decent performance as well (the UHD Graphics has to make do with no dedicated video memory).

Power consumption

The i3's base power consumption (also known as the default TDP or Power Limit 1) is 28 W; its "minimum assured" power consumption sits at 20 W. In the meantime, the maximum Turbo power consumption (also known as the PL2) is not supposed to exceed 64 W.

This 12th generation Intel chip is built with Intel's fourth-gen 10 nm process marketed as Intel 7 for decent, as of late 2022, energy efficiency. Expect the i3 to be significantly less power-hungry (and a lot easier to cool) than all other Alder Lake-P chips because of its lower core count.

Intel Core i7-10810U

The Intel Core i7-10810U is a power efficient hexa-core SoC for notebooks based on the Comet Lake (CML-U) generation and appeared in March 2020. 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 4.9 GHz. 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.

The CPU supports professional management features vPro (as a difference to the i7-10710U).

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.
