Intel Core i9-13900K tested before production against Core i9-12900KF. Differences in single-thread tests are up to 10%

Intel Core i9-13900K tested before production against Core i9-12900KF.  Differences in single-thread tests are up to 10%Just a couple of days ago we wrote about the results of the Intel Core i9-13900K processor, which came from the popular benchmark database GeekBench. It looks like there may be more of these tests (albeit from other programs) in the near future. Chinese sources have begun testing pre-production samples of the new 13th generation flagship Raptor Lake-S. Thanks to this, we can see how the system performs compared to the currently available Intel Core i9-12900KF processor.

The first performance tests of the Intel Core i9-13900K processor appeared on the Chinese website Bilibili. I’m still talking about the pre-production version, but now the single-chain performance with respect to the Core i9-12900K is 10% higher.

Intel Raptor Lake-S – new information about the processors will confirm support for DDR4 3200MHz and DDR5 5600MHz memory

According to the information From the Chinese Bilibili websiteThe pre-production version of the Intel Core i9-13900K processor offers a base clock of 3.0 GHz, which can be increased to 5.5 GHz using Turbo Boost 2.0 or 5.7 GHz with the help of Intel Thermal Velocity Boost. The exact same parameters were introduced earlier by the GeekBench benchmark. So it’s possible that the latest version of the Raptor Lake-S processor will offer the same or slightly higher clocks. What does the performance issue look like?

Intel Raptor Lake – Everything you need to know about the 13th generation processors for desktop and laptop computers

For example, in the Cinebench R23, the Intel Core i9-13900K chip scored 2,198 points, which is 13.53% better than the Core i9-12900KF (1936 points). However, tests show that the average top model Raptor Lake-S in the current version is about 10% more powerful than the representative of the 12th generation Alder Lake-S. In the multi-threading test of the Cinebench R23, the Core i9-13900K chip actually required 37,232 points, which is about 40% better than the Core i9-12900KF (26547 points). In the other tests, the multithreaded scores are also significantly higher, thanks to both the higher clocks as well as the additional eight cores that push the multithreaded test results even further.

The fact that performance (especially a single thread) is also dependent on higher clocks can be inferred from the screen below, which shows the results of Intel Core i9-13900K and Core i9-12900K processors at different times. In the case of 5.0 GHz, 5.1 GHz, and 5.2 GHz systems, we can see that the single-thread test results in CPU-Z are almost at the same level, and the differences can be closed within the measurement error. Chinese testers used AiO 360 mm to cool the processor, but the processor quickly warmed up to 100 degrees. The PL4 factor (hence literally instant load) is also pretty high, and it looks like it’s set at 420W.
