We continue to see more and more leaked clues of the Intel Core i9-13900K, high-end processor from the Raptor Lake platform. As usual we are talking about an engineering sample, but this time the information is expanded, and it is that by limiting this processor to the same frequencies as a Intel Core i9-12900KF, its Alder Lake equivalent, but without an integrated graphics card. This let us know that there are no improvements in the CPIthat is, at the same speed, it goes as fast as its previous generation counterpart.
Summarizing information, that your time is valuable, in CPU-Zthe Core i9-13900K is 9.41% faster in single-core performance compared to the Core i9-12900KF, while in multi-core performance the improvement is 46.34%. In the reference par excellence for processors, Cinebench R23improved single-core and multi-core performance is 13.53 and 40.25% respectivelyso it’s not bad at all.
If Raptor Lake doesn’t offer IPC improvements, why is it faster than Alder Lake?
Well it’s very simple, the Core i9-13900K achieves higher speeds, so all the performance gain is related at increased frequencies.. In multi-core performance, the performance improvement is much more noticeable, since it must be remembered that low-power cores doubledthus going from 8 of these hearts to no less than 16.
If we focus on other benchmarks, like physics in 3DMark, we see an improvement in the performance of 43.34%. As a rule, in all benchmarks there are noticeable performance improvements, although unfortunately there are no benchmarks in games, and in games the number of cores will not have so much importance, but the improvement in performance will be linked increase the speed of high-performance cores, and something that has little influence on benchmarks, which is cache increasesomething the games will take advantage of.
Same lithography + higher frequencies = an Intel Core i9-13900K with up to 420W of consumption
Raising frequencies while maintaining the manufacturing process involves an increase in energy consumption and temperaturess, and interestingly, this Core i9-13900K suffered from temperature issues even using a All-in-one liquid 360 mm (maintenance free conventional liquid with 3 x 120mm fans). This resulted in a throttling with loss of performance by reaching the 100ºC with a maximum consumption peak (PL4) of 420Walthough in the test he almost touched, reaching the 399W.
Of course, this consumption will never be reached with normal CPU usage (games, publishing, etc.), it could be around 250Wbut makes it clear that Intel needs Raptor Lake not delayed to really significantly reduce energy consumption.
