► remove from comparison![Intel i5-14500HX](fileadmin/_processed_/b/7/csm_Intel_Core_i7_badge_2020_12f92179ae.jpg)
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).
Intel Core i7-12650HX

The Intel Core i7-12650HX is a high-end mobile CPU for laptops based on the Alder Lake architecture. It was announced in mid 2022 and offers 6 of the 8 performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 20 supported threads when combined with the E-cores. The clock rate ranges from 2.0 to 4.7 GHz on the performance cluster and 1.5 to 3.3 GHz on the efficiency cluster. The performance of the E-cores should be similar to old Skylake cores (compare with the Core i7-6920HQ). All cores can use up to 25 MB L3 cache. The CPU offers an open multiplicator and therefore the possibility to overclock the CPU cores. Compared to the similar i7-12850HX, the 12800HX does not offer vPro or ECC memory support.
Performance
Due to the similar specs, the performance of the 12650HX should be similar to the Core i7-12700H (14 cores, max 4,7 GHz, 45 W TDP). Thanks to the higher TDP, the sustained performance could be better (if the cooling of the laptop is sufficient).
Features
The integrated memory controller supports various memory types up to DDR5-4800 and DDR4-3200. The Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficient cores for the best performance. For AI tasks, the CPU also integrates GNA 3.0 and DL Boost (via AVX2). Quick Sync in version 8 is the same as in the Rocket Lake CPUs and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC, and AV1 decode in hardware. The CPU supports 48 PCIe lanes consisting of 16 Gen5 (x16 or 2x8), 20 Gen4 and 12 Gen3.
The integrated graphics card is based on the Xe-architecture and offers 32 EUs (Execution Units) operating at up to 1.45 GHz.
The CPU is rated at 55 W base power (157 W PL2). The SoC is manufactured on a 10nm process at Intel, which is known as Intel 7.
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.
