Intel Core i9-12900HK vs Intel Core i7-13700K vs Intel Core i9-13900K

Intel Core i9-12900HK

The Intel Core i9-12900HK is a high-end mobile CPU for laptops based on the Alder Lake architecture. It was announced in early 2022 and offers 6 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 2.5 to 5 GHz on the performance cluster and 1.8 to 3.8 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 24 MB L3 cache. As a K-variant, the CPU offers an open multiplicator and therefore the possibility to overclock the CPU cores. Compared to the similar i9-12900H, the 12900HK only offers the "Essentials" features of vPro.

Performance

The average 12900HK in our database is in the same as the Core i9-13900H, as far as multi-thread benchmark scores are concerned. It's also almost as fast as the Ryzen 7 7745HX and the Core i5-13500HX. This is a super-fast processor, as of mid 2023; it will have no issues running any app or any game for at least two more years.

Thanks to its decent cooling solution and a long-term CPU power limit of 134 W, the Alienware x17 R2 P48E is among the fastest laptops built around the 12900HK that we know of. It can be more than 40% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Features

The integrated memory controller supports various memory types up to DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. 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 only supports PCIe 4.0 (x8 for a GPU and two x4 for SSDs).

The integrated graphics card is based on the Xe-architecture and offers 96 EUs (Execution Units) operating at up to 1.45 GHz.

Power consumption

This Core i9 series chip has a "minimum assured" power consumption of 35 W, with 45 W being its Base power consumption. The maximum Intel-recommended Turbo power consumption sits at 115 W.

The i9-12900HK is manufactured on Intel's 4th generation 10 nm process marketed as Intel 7 for lower-than-average, as of mid-2023, energy efficiency.

Intel Core i7-13700K

The Intel Core i7-13700K is a high-end CPU based on the current Raptor Lake architecture, which was introduced in September 2022. The base clock is 3.4 GHz and can reach up to 5.4 GHz under optimal conditions. The total of 16 cores are divided into 8 P-cores and 8 E-cores, which we already know from the Alder Lake architecture. Compared to the Intel Core i7-12700K, however, the number of E-cores has been doubled, meaning that the Intel Core i7-13700K now offers 24 threads. As usual, the K models continue to offer a freely selectable multiplier, which simplifies overclocking. In addition, all new Raptor Lake processors can be operated on the existing Socket 1700 motherboards.

Performance

Compared to the Intel Core i7-12700K, the Core i7-13700K still offers 8 P-cores, but these are to be relieved by 8 additional E-cores for demanding applications. The E-cores primarily take care of background applications. The hybrid architecture relies on the Intel Thread Director, which is responsible for the correct allocation of tasks. Compared to Alder Lake, the number of e-cores has been doubled, which significantly improves multi-thread performance in combination with a further increase in IPC. If all requirements are met, Intel Turbo Boost 3.0 can increase the clock rate of the P-cores to up to 5.4 GHz. The E-cores can also be overclocked and reach a maximum of 3.4 GHz.

Graphics

Like the Intel Core i7-12700K, the Intel Core i7-13700K offers an integrated graphics unit (iGPU). The Intel Iris Xe architecture continues to serve as the basis. In terms of performance, however, not much has changed with the new Intel UHD Graphics 770.

Power Consumption

The Intel Core i7-13700K is specified with a TDP of 125 watts, which corresponds to the PL1 value. In Boost mode, the processor's performance can increase to up to 253 watts (PL2). However, this requires good cooling. If all restrictions are deactivated in the BIOS, the PL2 value is not restricted by a Tau value.

Intel Core i9-13900K

The Intel Core i9-13900K is a fast high-end desktop processor of the Raptor Lake series. It includes a hybrid architecture for the CPU cores with combined 24 cores and 32 threads. Eight fast Raptor Cove performance cores (P-cores) with HyperThreading and a clock speed of 3 - 5.8 GHz and sixteen Gracemont efficiency cores without HyperThreading and a clock speed of 2.2 - 4.3 GHz.

Thanks to the faster P-cores and more E-cores, the i9-13900K is significantly faster than the old i9-12900K (especially in multi-threaded workloads). Compared to the Raphael AMD Ryzen 9 7950X (Zen 4), the 13900K offers a slightly higher multi-thread-performance and a slightly lower single core performance. In games, the Intel CPU is currently the clear winner (at the time of announcement of the 7950X).

The 13900K is rated at 125 Watt TDP base power (PL1) and 253 Watt Turbo Power (PL2) and therefore slightly higher than the old i9-12900K.
