Intel Core i7-14650HX vs Intel Core i7-13700HX

Intel Core i7-14650HX

The Intel Core i7-14650HX is a high-end CPU based on the new Raptor Lake architecture for large and heavy notebooks. The CPU was introduced at the beginning of 2024 and is similar to the older Core i7-13700HX except for slightly higher CPU clock rates (max 200 MHz).

The total of 24 threads are divided into P-cores and E-cores, which we already know from Alder-Lake. The 13700HX offers 8 performance cores (P-cores) with hyperthreading and 8 efficiency cores (E-cores) without hyperthreading. A total of 20 threads are therefore supported. The P-cores clock from 2.2 to 5.2 GHz (single core) or 4.5 GHz (all cores) and the E-cores from 1.6 to 3.7 GHz. The integrated memory controller supports a maximum of DDR5 with 4800 MHz (and not 5600 MHz like the i9 HX models).

Compared to Alder Lake, the new Raptor Lake architecture offers improved P-cores (Raptor Cove architecture with more cache), more E-cores (same Gracemont architecture) and higher clock rates thanks to the improved Intel 7 process. Furthermore, Intel now supports faster DDR5 main memory in the top models (up to 5600 MHz in the i9).

The performance should be slightly above the older Core i7-13700HX (with the same TDP settings and cooling). This makes the CPU ideal for demanding tasks and games.

The 14650HX continues to be manufactured using Intel's improved 10nm FinFET process (Intel 7 process) and is specified with 55 watts of base power and 157 watts of turbo power.

Intel Core i7-13700HX

The Intel Core i7-13700HX is a fast high-end mobile processor of the Raptor Lake series. Is was announced in early 2023 and is based on the desktop Core i7-13700K with combined 16 cores and 24 threads. Eight fast Raptor Cove performance cores (P-cores) with HyperThreading clocking between 2.1 - 5 GHz (4.5 GHz all core boost) and eight Gracemont efficiency cores without HyperThreading (1.5 - 3.7 GHz).

Compared to Alder Lake, Raptor Lake offers improved P-Cores (Raptor Cove micro-architecture) with bigger Caches and more E-Cores (same Gracemont micro-architecture). Furthermore, the chip supports faster DDR5 memory (up to 5600 MHz for the 13980HX, but only 4800 MHz for the i7).

Performance

The average 13700HX in our database is in the same league as the i7-13650HX, as far as multi-thread benchmark scores are concerned, and thus outguns the Ryzen 7 7745HX by a significant margin. This is a very fast chip, as of early 2023.

Thanks to its powerful cooling solution and a long-term CPU power limit of 122 W, the Uniwill GM6PX7X is among the fastest laptops built around the 13700HX that we know of. It can be at least 10% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

The chip's "minimum assured" power consumption sits at 45 W. Its Turbo power consumption is not supposed to exceed 157 W; its Base power consumption is supposed to be around 55 W. Most laptop makers will probably go for a value much higher than 55 W to get better performance.

This Raptor Lake family processor is built with Intel's 4th generation 10 nm process marketed as Intel 7 for average, as of early 2023, energy efficiency.
