Intel Core i7-13850HX vs Intel Core i5-14450HX

Intel Core i7-13850HX

The Intel Core i7-13850HX is a fast high-end mobile processor of the Raptor Lake series. Is was announced in early 2023 and offers combined 20 cores and 28 threads. Eight fast Raptor Cove performance cores (P-cores) with Hyper-Threading and eight Gracemont efficiency cores without HyperThreading. The 13850HX supports the full enterprise set of vPro management features.

The eight P-Cores are clocked from 2.1 GHz (base) up to 5.3 GHz (single core boost, all cores up to 4.7 GHz). The twelfe E-Cores clock between 1.5 (base) and 3.8 GHz (boost).

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 13850HX).

Performance

While we have not tested a single system built around the 13850HX as of August 2023, we fully expect the chip to be at least a couple pecentage points faster than the i9-12900HX, a CPU featuring eight P-cores and eight E-cores that run at nearly the same clock speeds as what the 13850HX has. Just how wide the performance delta will be will depend a lot on how competent the laptop's cooling solution is, and how high the CPU power limits are.

Power consumption

The chip's "minimum assured" power consumption sits at 45 W. Its Intel-recommended "Maximum Turbo" power consumption is 157 W while the 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 extract as much performance out of the chip as possible.

This Core i7 series processor is built with Intel's 4th generation 10 nm process marketed as Intel 7 for average, as of early 2023, energy efficiency.

Intel Core i5-14450HX

The Intel Core i5-14450HX is a mid-range CPU with 10 cores based on the Raptor Lake refresh series for large and heavy notebooks.

The total of 16 threads are divided into P-cores and E-cores, which we already know from Alder Lake. The 13450HX offers 6 performance cores (P-Cores, Raptor Cove or Golden Cove) with hyperthreading and 4 efficiency cores (E-Cores, Gracemont) without hyperthreading. The P-cores clock from 2.4 GHz (base clock) to 4.8 GHz (all cores) or 4.6 GHz (single core). The E-cores clock from 1.8 - 3.5 GHz. Compared to the older Core i5-13450HX the CPU cores are clocked slightly higher.

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. In addition, Intel now supports faster DDR5 main memory in the top models (up to 5600 MHz, in the refresh now also in the i5).

The 14450HX is manufactured in the further improved 10nm FinFET process at Intel (Intel 7 process) and is specified with 55 watts base power and 157 watts turbo power.
