Intel Core i7-14700HX vs Intel Core i5-14500HX

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 i5-14500HX

The Intel Core i5-14500HX is a high-end CPU from the Raptor-Lake-HX Refresh series (RPL-H). The CPU offers all 6 performance cores (P-cores, Golden Cove or Raptor Cove architecture) and 8 efficiency cores (E-cores, Gracemont architecture). The P-cores support hyperthreading (therefore 20 threads together) and clock from 2.4 to 4.9 GHz (single-core turbo). The E-cores clock from 1.9 - 3.7 GHz and should offer comparable performance to old Skylake cores (e.g. i7-6920HQ).

Performance

Thanks to the higher clock rates of the Rocket Lake series, the i5-14500HX can reach the level of the old Core i9-12900H and is therefore a very fast mobile CPU that is ideal for all areas of application.

Graphics unit

Like its predecessor, Intel integrates an Intel Xe-based graphics unit. In the 14500HX, all 96 EUs are activated and clock at up to 1.55 GHz.

Features

Like Alder-Lake-H, Raptor-Lake-H has partially integrated WiFi 6E and Thunderbolt 4 (4x). The integrated memory controller now supports faster DDR5-5200 memory. The integrated Gaussian and Neural Accelerator (GNA) is still installed in version 3.0. The Quick Sync 8 media engine is the same as in Rocket Lake and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC and AV1 decode. The chip supports PCIe 5.0 x8 for a dGPU and two PCIe 4.0 x4 for SSDs. The PCH also offers PCIe Gen3 x12.

Power consumption

The Intel Core i5-14500HX is specified with 55 watts TDP (PL2 157 watts). The processor continues to be manufactured using the improved Intel 7 process (10 nm SuperFin).
