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.
The Intel Core i5-1345U is a mid-range mobile CPU for thin and light laptops based on the Alder Lake architecture (Raptor Lake-U / RPL-U series). It was announced in early 2023 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 1.6 to 4.7 GHz on the performance cluster and 1.2 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. The CPU supports "Enterprise" vPro management features. Compared to the P-series (28W) or H-series (45W), the 15W TDP may limit the sustained performance.
Performance
Thanks to the similar clock speed, the Core i5-1345U is very similar to the older Core i7-1255U (+100 MHz P-Cores base clock rate). The faster i7 like the i7-1365U models offer only higher clock rates (and a faster iGPU).
Architecture
The integrated memory controller supports various memory types up to LPDDR5-6400. 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 still only supports PCIe 4.0 x8 for a GPU and two PCIe 4.0 x4 for SSDs.
The integrated graphics card is based on the Xe-architecture and offers 80 of the 96 EUs (Execution Units) operating at up to 1.25 GHz.
Power consumption
This Core i5 CPU is rated at a TDP of 15W (base power, PL1) and a maximum turbo power of 55W (PL2). The RPL-U processors are built in a further improved Intel 7 process (10nm SuperFin) that allows higher clock rates.
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.
