Intel Core i9-13900HX vs Intel Core i7-14650HX vs Intel Core i7-13650HX

Intel Core i9-13900HX

The Intel Core i9-13900HX is a fast high-end mobile processor of the Raptor Lake series. Is was announced in early 2023 and looks like it is based on the desktop Core i9-13000K with combined 24 cores and 32 threads. Eight fast Raptor Cove performance cores (P-cores) with HyperThreading that clock between 2.2 GHz (base) and 5.4 GHz (single core boost, 4.9 GHz for all cores) and sixteen Gracemont efficiency cores without Hyper-Threading (1.6 - 3.9 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 13900HX).

Performance

The average 13900HX in our database is in the same league as the Core i9-13950HX and the Ryzen 9 7845HX, as far as multi-thread benchmark scores are concerned. This is really impressive, to say the least.

Thanks to its decent cooling solution and a long-term CPU power limit of 99 W, the Eluktronics Mech-17 GP2 is among the fastest laptops built around the 13900HX that we know of. It can be about 50% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

The CPU is still produced in a further improved 10nm FinFET process (Intel 7) that allows the higher clock speeds. The power consumption is specified at 55W base power up to 157 Watt max. Turbo power.

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 i7-13650HX

The Intel Core i5-13650HX is a fast high-end mobile processor of the Raptor Lake series. Is was announced in early 2023. The CPU integrates 6 fast Raptor Cove performance cores (P-cores) with Hyper-Threading and 8 Gracemont efficiency cores without HyperThreading. The P-Cores clock between 2.6 GHz (base) up to 4.9 GHz (single core boost, all-core 4.5 GHz). The smaller E-Cores clock between 1.9 and 3.6 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 i5).

Performance

The average 13650HX in our database is in the same league as the Core i7-13700HX and the Core i9-12950HX, as far as multi-thread benchmark scores are concerned.

Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.

The CPU is still produced on a further improved 10nm FinFET process (Intel 7) that allows the higher clock speeds. The power consumption is specified at 55W base power up to 157 Watt max. Turbo power.
