Intel Core i5-14450HX vs Intel Core i9-14900HX

Intel Core i5-14450HX

► remove from comparison Intel 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.

Intel Core i9-14900HX

► remove from comparison Intel 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 unit

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 in 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.
