While Cinebench R23 and CPU-Z show single digit performance gains over the i5-13600K, the overhauled Cinebench 2024 methodology shows up to 14% improvement in multi-thread tests. The negligible gains are mainly due to the same ^P+8E core configuration from last year’s model, with only a 200 MHz boost for the maximum frequencies.
Chinese reviewer ECSM recently revealed in a Bilibili post some benchmark results for the upcoming Intel Core i5-14600K desktop processor from the Raptor Lake Refresh family. ECSM notes that this is an engineering sample so performance for the final version may vary slightly. Nevertheless, the performance gains over the i5-13600K seem negligible so the price is expected to match last year’s model.
This is mainly explained by the core configuration that remained unchanged from the i5-13600K, with 6 performance cores and 8 efficiency cores. However, Intel boosted the max clocks from 5.1 to 5.3 GHz, even though the new i5 still does not include Turbo Boost or Thermal Velocity Boost support. By default, the i5-14600K has a 125 W TDP, but in order to boost to 5.3 GHz, the TDP needs to jump to 160 W. The engineering sample tested by ECSM exhibited a rather high voltage exceeding 1.4 V. This could be fixed with a decent motherboard that allows undervolting.
Besides the usual Cinebench R23 and CPU-Z tests, ECSM also used the new Cinebench 2024 suite where the i5-14600K showed the greatest performance increase over the i5-13600K, with a single core difference of 8% and a multi-core delta of 14%. Conversely, Cinebench R23 showed the lowest gains, with close to 0% for the single core test and 3% for the multi-core test, while CPU-Z reported 6% improved single core performance and 4% multi-core gains.

I first stepped into the wondrous IT&C world when I was around seven years old. I was instantly fascinated by computerized graphics, whether they were from games or 3D applications like 3D Max. I’m also an avid reader of science fiction, an astrophysics aficionado, and a crypto geek. I started writing PC-related articles for Softpedia and a few blogs back in 2006. I joined the Notebookcheck team in the summer of 2017 and am currently a senior tech writer mostly covering processor, GPU, and laptop news.
