Intel Core i9-14900HX vs Intel Core i9-13900HX

Intel Core i9-14900HX

The Intel Core i9-14900HX is a high-end CPU based on the Raptor Lake architecture for large and heavy notebooks. The CPU was introduced at the beginning of 2024 and is a slightly higher clocked variant of the older Core i9-13980HX.

The total of 32 threads are divided into P-cores and E-cores, which we already know from Alder-Lake. Here, 8 performance cores (P-cores) with hyperthreading are used and 16 efficiency cores, so that a total of 32 threads can be processed simultaneously. The P-cores clock from 2.2 GHz (base clock) to 5.8 GHz (single-core turbo) and the E-cores from 1.6 GHz to 4.1 GHz.

Performance

Due to the slightly higher maximum clock rates, the single-core performance of the 14900HX in particular increases slightly compared to the 13980HX. Compared to AMD's top model, the Ryzen 9 7945HX or 7945HX3D the 14900HX comes in just behind (on average in our benchmarks). However, the performance depends on the benchmark and the cooling and is usually very comparable.

Graphics

Like the Intel Core i9-12900HX, the Intel Core i9-14900HX offers an integrated graphics unit. The Intel Iris XE architecture continues to serve as the basis. In terms of performance, however, not much has changed with the Intel UHD Graphics 770.

The 14900HX is manufactured on the improved 10nm FinFET process at Intel (Intel 7 process) and is specified with 55 watts of base power and 157 watts of turbo power.

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.
