The Intel Core i7-1250U is a 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 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 12 supported threads when combined with the E-cores. The clock rate ranges from 1.1 to 4.7 GHz on the performance cluster and 0.8 to 3.5 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 12 MB L3 cache. Compared to the similar Core i7-1260U, the 1250U only offers "Essentials" vPro management features.
Performance
The average 1250U in our database is in the same league as the Ryzen 5 5500U; the i5-1240U, the i7-1260U and the i7-1265U are found close nearby as well.
Thanks to its decent cooling solution and a long-term CPU power limit of 23 W, the Envy x360 13-bf0013dx is among the fastest laptops built around the 1250U 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.
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 adapter is based on the Xe architecture and offers all 96 EUs (Execution Units) operating at up to 0.95 GHz.
The CPU is rated at 9 W base power (TDP, PL1) and 29 W max. Turbo power (PL2) and the whole SoC is manufactured on a 10nm process at Intel, which is known as Intel 7.
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.
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.
