As part of the Raptor Lake desktop processors announcement, Intel confirmed that there will be another flagship processor in the future that can automatically overclock to 6GHz out of the box. Officially, the manufacturer did not announce the name of this model, but it is obvious that it was about the Core i9-13900KS. The recent major Intel chip leak has confirmed these speculations and revealed the full specs of the upcoming CPU selected.
The Core i9-13900KS is a 24-core processor with eight powerful P-cores and 16 energy-efficient E-cores. The processor supports 32 threads. Turbo Boost Max 3.0 technology allows the 1-2 most productive cores to automatically overclock to a frequency of 5.8 GHz. An additional 200MHz automatic overclocking to the same 6GHz is provided by Thermal Velocity Boost technology. The base clock of the Core i9-13900KS with big cores is also 200MHz faster than the regular Core i9-13900K at 3.2GHz. At the same time, the energy-efficient cores of the KS version work in the same frequency range – from 2.2 to 4.3 GHz.
The nominal power consumption of the Core i9-13900KS has increased from 125 to 150 watts. However, the maximum consumption has not changed and is 253 watts. The chip supports the same RAM standards as all other Raptor Lake processor models – DDR4-3200 and DDR5-5600.
Shortly after the above leak, the first data on the performance of the Core i9-13900KS appeared on the web in the Geekbench Synthetic Test. The processor was tested in a system with an ASUS ROG Z790 Maximus Hero motherboard and 32 GB DDR5-7200 RAM.
Detailed telemetry data from three Geekbench benchmarks shows that the Core i9-13900KS auto-overclocks to 5893MHz on multiple cores, but its average clock speed was 5867MHz.
The processor achieved up to 2,319 points in the single-core performance test and up to 26,774 points in the multi-core performance test. This means that its single-core performance is on average 10% higher than that of its predecessor, the Core i9-12900KS (Alder Lake), and the multi-core performance is 39% higher.
The Core i9-13900KS is expected to be officially unveiled at CES 2023 in early January. It is scheduled to go on sale in the first quarter of next year.
