Intel Core i5-1340P vs Intel Core i7-10810U

Intel Core i5-1340P

The Intel Core i5-1340P is a mid-range Raptor Lake-P (Alder Lake-P refresh) family CPU, a 28 W part meant for use in ultra-light, ultra-thin (yet actively cooled) laptops. This CPU was announced in early 2023 and it has 4 of the 6 performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores are Hyper-Threading-enabled and clock from 1.9 GHz (base) up to 4.6 GHz (single core boost) for a total of 16 threads when combined with the E-cores. The clock speeds of the E-cores ranges from 1.4 to 3.4 GHz and offer a similar performance as the old Skylake cores.

The performance should be similar to the old Core i7-1250P and therefore well suited for even demanding tasks.

The CPU still only supports PCIe 4.0 x8 for a GPU and two PCIe 4.0 x4 for SSDs.

The i5-1340P is rated at 28 Watt tDP (PL1, 64 Watt PL2 for short bursts). The CPU is manufactured in the further improved Intel 7 process (10nm SuperFin).

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.
