The i7 is a continuation of Intel's efforts to use the ARM-developed big.LITTLE technology for its own benefit. The i7's shortcomings as compared to Intel Core i7-1270P include the marginally lower clock speeds and limited vPro feature set ('Essentials' tier only, not allowing for remote device management). The clock speeds range from 2.1 GHz to 4.7 GHz for the performance cluster and 1.5 GHz to 3.4 GHz for the efficient cluster.

The P-cores are Hyper-Threading-enabled for a total of 16 threads when combined with the E-cores. It was announced in early 2022 and it features 4 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 Intel Core i7-1260P is an upper mid-range 28 W Alder Lake CPU designed for use in ultra-light laptops. Intel Core i7-1260P ► remove from comparison The R5 7645HX is rated at a TDP of 55 Watt and can be configured up to 75 Watt (cTDP). The chip integrates 4x USB 3.2 Gen2 (10 Gbps) ports (no USB4), 28 PCIe 5.0 lanes (for GPU and SSDs) and a dual-channel DDR5-5200 memory controller. The Dragon Range series still uses a chiplet design with two CCD-clusters (each with 8 possible cores, the 7645HX only uses one CCD with 6 of the 8 cores) in 5nm and an IO-die (including the memory controller and the Radeon 610M iGPU) in 6nm. This means even the old Ryzen 9 6980HX (also 5 GHz, but Zen 3) should be slightly slower in single threaded workloads. Especially single threaded performance should be very good thanks to the new Zen 4 cores and relatively high clock speeds. The performance of the R5 7645HX should be significantly higher than the fastest 6-core CPU of the Ryzen 6000 mobile series the Ryzen 5 6600H. The cores clock from 4 (base) up to 5 GHz (single core boost). It offers 6 cores based on the Zen 4 architecture that supports hyperthreading (12 threads). The AMD Ryzen 5 7645HX is a fast high-end laptop processor of the Dragon Range series. AMD Ryzen 5 7645HX ► remove from comparison
