Intel’s regular 13th Gen Core ‘Raptor Lake’ processors are just around the corner, but the company’s limited edition Core i9-13900KS is months away. However, it appears that some Chinese PC makers already have samples of the aforementioned CPUs to prepare for launch and even test their performance.Results published in Chinese Bilibili and discovered by HXLAfter all, the upcoming Core i9-13900KS is a very powerful chip as it can leave behind not only all Raptor Lake processors, but even AMD’s shiny new Ryzen 9 7950X.
Intel’s Core i9-13900K processor features 8 high-performance Raptor Cove cores and 16 energy-efficient Gracemont cores, just like other top-of-the-range Raptor Lake CPUs. While other Core i9-13900K processors can boost their performance cores to 5.80 GHz (with 1 or 2 cores), the Core i9-13900KS promises a boosted clock speed of 6.0 GHz. In addition to this, however, the limited Core i9-13900KS version also supports a 350W turbo mode, further increasing boost clocks depending on motherboard quality and cooling system capabilities.
This 350W mode is the ultimate way to boost the single-threaded performance of Intel’s upcoming limited edition Core i9-13900KS processor, possibly the company’s secret weapon against AMD’s Ryzen 9 7950X processor based on the Zen 4 microarchitecture. On the other hand, the Core i9-13900KS’ higher clocks naturally affect its performance in multi-threaded workloads.

At least the early performance numbers for the Core i9-13900KS from the CPU-Z benchmark (version 2.0.2.0) show not only chips like the Core i9-12900KS and Core i9-13900K, but also AMD’s Ryzen 9 7950X. It shows that you are leaving it behind. Both single-threaded and multi-threaded performance.

| Core i9-13900KS | 982.5 | 18453.4 |
| Core i9-13900K | 893 | 16877 |
| Core i9-12900K | 819 | 11424 |

I don’t know the exact hardware configuration tested by the owner of the Core i9-13900KS sample. Second, we’re dealing with a prototype CPU with unknown specs and cooling. Cooling is obviously essential for he 350W mode, and anyone using the LN2 can get record results.
Please note that the CPU-Z benchmark is a basic synthetic benchmark and may reflect performance in some real-world applications and not in other programs.
Taking into account all the aforementioned factors, the results of these CPU-Z tests should be taken with a grain of salt. Nevertheless, if the results are accurate, they are impressive for the Core i9-13900KS.
