Intel Core i7-14700HX vs Intel Core i7-13650HX vs Intel Core i9-14900HX

Intel Core i7-14700HX

The Intel Core i7-14700HX 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 as part of the Raptor Lake HX refresh. The i7-14700HX is similar to the Core i7-13850HX with slightly higher clocked CPU cores.

The total of 28 threads are divided into P-cores and E-cores, which we already know from Alder Lake. The 14700HX offers 8 performance cores (P-cores) with hyperthreading and 12 efficiency cores (E-cores) without hyperthreading. A total of 28 threads are therefore supported. The P-cores clock at up to 5.5 GHz (single core) and the E-cores up to 3.9 GHz. The integrated memory controller supports a maximum of DDR5 with 5600 MHz.

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 (up to 5600 MHz) in the top models.

The 14700HX is manufactured on the older 10nm FinFET process at Intel (Intel 7 process) and is specified with 55 watts base power and 157 watts 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.

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.
