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).
The Intel Core i9-12950HX is a high-end mobile CPU for laptops based on the Alder Lake architecture. It was announced in mid 2022 and offers 8 performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 24 supported threads when combined with the E-cores. The clock rate ranges from 2.3 to 5 GHz on the performance cluster and 1.7 to 3.6 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 30 MB L3 cache. As a HX-variant, the CPU offers an open multiplicator and therefore the possibility to overclock the CPU cores. Compared to the similar i9-12900HX, the 12950HX supports vPro and ECC memory (successor of the Xeon line) but the CPU overclocking is limited.
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 adapter is based on the Xe-architecture and offers 32 EUs (Execution Units) operating at up to 1.55 GHz.
Performance
The average 12950HX in our database is in the same league as the Core i7-13650HX, Core i7-13700HX, Core i9-13900HK, as far as multi-thread benchmark scores are concerned. This is a very fast chip, as of early 2023.
Thanks to its decent cooling solution and a long-term CPU power limit of 82 W, the ThinkPad P16 G1 is among the fastest laptops built around the 12950HX that we know of. It can be 30% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.
Power consumption
The chip's "minimum assured" power consumption is 45 W. Its Turbo power consumption is not supposed to go over 157 W and its Base power consumption is supposed to be around 55 W. Most laptop makers will probably go for a higher value than 55 W to get better performance.
The i9-12950HX is built with Intel's 4th generation 10 nm process marketed as Intel 7 for average, as of early 2023, energy efficiency.
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 13700HX 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 13700HX is manufactured in the older 10nm FinFET process at Intel (Intel 7 process) and is specified with 55 watts base power and 157 watts turbo power.
