A video test purported to be the Intel Core i9-13900KF Qualification Sample (QS) has been posted online. We’ve previously seen videos and benchmarks purported to be a Core i9-13900 CPU, but this time a high performance liquid loop chiller is used to cool the chip. We found that the new Raptor Lake flagship’s P-core can run stably at up to 6.1 GHz in some benchmarks with this thermal solution.
Bilibili PC Tech Social Media Star extreme player is back with some more testing and reflection on his claimed Intel Core i9-13900KF QS chip. The last time we saw this fellow, he tested what would be Raptor Lake’s flagship against its Alder Lake counterpart, namely the Core i9-12900KF. This time, Extreme Player wanted to see how well the Core i9-13900KF QS would perform with a little tuning and the use of a liquid cooler.
The main findings of Extreme Player are Twitter’s HXLHowever, we’ve put together a comparison that folds in the results of the previous air-cooled 13900 from Extreme Player.

Data for previous and new videos in Extreme Player.
We can see off-the-shelf Alder Lake CPUs going up against comparable QS models in the new Raptor Lake. Liquid cooling allows for some nice and stable overclocks, according to Extreme Player testing. The nT (multi-threaded) test in the table shows a stable all-core frequency (performance cores) of 6.1 GHz in CPU-Z and 5.8 GHz in Cinebench. For the air-cooled Core i9-13900, the all-core boost was 5.5 GHz. Alder Lake chips, on the other hand, feature an all-P core boost of 5.2 GHz.
Other key findings for Extreme Player are Efficiency Cores or E-cores running stably at all-cores up to 5.2 GHz with CPU-Z using a water-cooled Core i9-13900 hooked up to an Asus ROG Maximus Z690 Apex It was possible. All-core up to 4.7 GHz on Cinebench R23.
Later in the Chinese audio/subtitle video, Extreme Player runs some memory tests to examine the performance of other Intel Raptor Lake samples such as the i7-13700K QS and i5-13600K QS. I don’t think these results are too early with these early chips, BIOS files, and pre-700 series chipsets. In fact, given that all of these early results are from a chip that’s claimed not to be ready for release yet, we should probably take it with a grain of salt.
