Intel Core i5-14450HX vs Intel Core i5-13505H vs Intel Core i5-13600H

Intel Core 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 i5-13505H

The Intel Core i5-13505H is a mid-range mobile CPU for laptops based on the Raptor Lake-H series (Alder Lake or Raptor Lake architecture). It was announced in early 2023 and offers 4 of the 6 performance cores (P-cores, Golden Cove architecture) and all 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 16 supported threads when combined with the E-cores. The clock rate ranges from 2.6 to 4.7 GHz (single core boost, all core up to 4.6 GHz) on the performance cluster and 1.9 to 3.5 GHz on the efficient cluster. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 18 MB L3 cache. Similar to the i5-13500H but without vPro support and the 13505H uses a different package and socket.

Performance

Thanks to the higher clock speeds of the improved Intel 7 process, the Core i5-13505H can surpass the old Core i5-12600H (e.g., + 200 MHz boost). The performance should be identical to the Core i5-13500H.

Features

The integrated memory controller supports various memory types up to DDR5-5200 (up from DDR5-4800 of the i5-12500H). 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 now supports PCIe 5.0 x8 for a GPU and two PCIe 4.0 x4 for SSDs.

The integrated graphics card is based on the Xe-architecture and offers 80 of the 96 EUs (Execution Units).

The CPU is rated at 45 W base power (95 W PL2) but most laptops will use a PL1 of around 60 Watt. The SoC is manufactured in a further improved 10nm process at Intel, which is known as Intel 7.

It was announced in early 2023 and offers 4 of the 6 performance cores (P-cores, Golden Cove architecture) and all 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 16 supported threads when combined with the E-cores. The clock rate ranges from 2.8 to 4.8 GHz (single core boost, all core up to 4.7 GHz) on the performance cluster and 2.1 to 3.6 GHz on the efficient cluster. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 18 MB L3 cache. Compared to the 12650H, the 12600H offers less P-cores but more E-cores, a faster iGPU and "Enterprise" vPro features (for remote management).
