Intel Core i5-9400F vs Intel Core i9-13900HK vs Intel Core i9-9900KS

Intel Core i5-9400F

Intel Core i9-13900HK

The Intel Core i9-13900HK is a high-end mobile CPU for laptops based on the Raptor Lake-H series (Alder Lake architecture). It was announced in early 2023 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 2.6 to 5.4 GHz (single core turbo, all-core 4.9 GHz) on the performance cluster and 1.9 to 4.1 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 i9-12900HK, the 13900HK offers higher clock speeds. Compared to the i9-13900H, the 13900HK only offers the "Essentials" features of vPro.

Performance

Thanks to the high core count and high clock speed, the Core i9-13900HK is the fastest 45W CPU for laptops and only bested by Raptor Lake-HX based models with more cores and improved P-cores (e.g., the i9-13980HX). Still, the CPU is very well suited for all demanding use cases like gaming, content creation, and scientific calculations.

Features

The integrated memory controller supports various memory types up to DDR5-5200 (up from 4800 MHz for the 12th gen). 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 96 EUs (Execution Units) .

The CPU is rated at 45 W base power (115 W PL2) but most laptops will use a PL1 of around 60 Watt. The SoC is manufactured in a 10nm process at Intel, which is known as Intel 7 (improved over the 12th Gen).

Intel Core i9-9900KS

The Intel Core i9-9900KS is a high end desktop processor that includes 8 cores based on the Coffee Lake architecture. It is the fastest Coffee Lake CPU in 2019 and compared to the similar named i9-9900K, the KS offers an all core Turbo of 5 GHz. All cores can clock between 4 GHz and 5 GHz and thanks to Hyperthreading / SMT 16 threads can be executed in parallel. The CPU is still manufactured in the mature 14 nm process (14nm++). Thanks to the open multiplicator, the CPU is rather easy to overclock (if a Z390 based mainboard is used).

With good cooling, the i9-9900KS can be around 10% faster than the older Intel Core i9-9900K (thanks to the 5 GHz all core Turbo). Compare to the old Core i7-8700K, the 9900KS is even 45% faster. Especially for gaming, the 9900KS is currently the fastest option available. The fast Ryzen and Threadripper CPUs from AMD however offer a better multithreaded performance.

The integrated GPU is called Intel UHD Graphics 630 and clocks with up to 1.2 GHz. It is not suited for demanding 3D games and located in the low end.

The TDP is raised to 127 Watt for the additional performance, therefore a good CPU cooler is needed. When overclocking the CPU, more than 200 Watt can be reached unter load.
