- Future-proofed thanks to support of DDR5 and PCIe 5.0
- 24 cores and 32 threads
The Intel Core i9-13900K is the flagship processor in the latest Raptor Lake (13th Gen) Series. It is built on x86 hybrid architecture, meaning that it can utilise both Performance (P-cores) and Efficient cores (E-cores) on a single die.
The Intel Core i9-13900K packs 24 cores (made up of 8 P-core and 16 E-cores) and 32 threads. This is a massive increase when looking at the preceding Alder Lake Intel Core i9-12900K, which featured 16 cores and 24 threads. Intel claims that Raptor Lake provides a 15% increase in single-threaded performance and a 41% boost to multi-threaded performance.
Moreover, the Intel Core i9-13900K supports both DDR5 RAM and PCIe 5.0 SSDs, meaning that you can upgrade to the latest components and raise the performance of your entire system. Unlike the AMD Ryzen 7000 Series, this chip also supports DDR4 memory if you don’t want to update all of your components at once since it can be a costly endeavour. Although that makes it even more important that you purchase the correct motherboard.
Intel claims that the i9-13900K can reach a max turbo frequency of 5.8GHz, a massive improvement on the 5.2GHz frequency of its predecessor. Not only should it allow for extremely smooth gameplay, but it also outpaces the flagship AMD Ryzen 9 7950X processor, which has a max boost clock speed of 5.7GHz. This is nothing to sniff at, but it maintains the trend of Intel jumping ahead of AMD in terms of single-core performance power.
This chip also comes with an Intel UHD Graphics 770 graphics card. While this can’t be used instead of a dedicated graphics card to play games or run intensive software, it is a good backup option if anything was to go wrong with your GPU.
In order to get a full look at how the Intel Core i9-13900K performs, I put it through a series of intensive benchmarks to check if Intel’s claims really hold true.
To ensure a fair test and to make sure that no processor has any unfair advantages, I made sure to use consistent components where possible. The build I used is listed below:
- AMD Motherboard: Gigabyte X670E Aorus Master
- Intel Motherboard: MSI Z790 Tomahawk Wi-Fi DDR4
- GPU: Nvidia GeForce RTX 3060 Ti
- Cooler: Corsair Hydro Series H150i PRO RGB 360mm liquid cooler
- OS: Windows 11
We unfortunately only had access to a DDR4 motherboard when testing the Intel Core processors, whereas we tested the AMD Ryzen 7000 chips with DDR5 memory. This may well be reflected in the benchmark results, so is worth keeping in mind, especially for holistic benchmarks such as PCMark.
I made sure to use of industry-standard benchmark software including PCMark 10, Geekbench 5 and Cinebench R23 to evaluate the performance. Moreover, to give gamers a better view of how this processor handles various titles, I have included in-game benchmarks from an array of games.
- Amazing single-core performance
- Outpaces the AMD Ryzen 9 7950X in most cases
- Multi-core performance is revolutionary
The Intel Core i9-13900K offers up fantastic performance and is arguably one of the best processors we’ve ever reviewed. It is the most powerful CPU in the latest Raptor Lake lineup and is by far the most powerful consumer chip that Intel has made yet. As we can see from the results below, the i9-13900K has some serious competition, notably from the AMD Ryzen 9 7950X, the flagship of the AMD Ryzen 7000 Series.
Single-core performance was extremely impressive, edging out the Ryzen 9 7950X in both Geekbench 5 and Cinebench R23. The multi-core performance in the Cinebench test was also very competitive, edging its AMD Ryzen rival, suggesting that this is the better choice for intensive tasks like 4K editing or animation.
We’ve compiled a chart of all the benchmark results so you can take a closer look at how the Intel Core i9-13900K really stacks up.
I also ensured to test out how this processor handles various games; these scores give a better indication of how many frame rates this CPU can produce for specific games. It’s important to note that a GPU will have a lot more impact on the performance of a game, so don’t expect to see massive differences between the Intel Core i9-13900K and a less powerful processor, like the Intel Core i5-13600K.
The high clock speeds delivered a great performance. The Intel Core i9-13900K was able to hit an average of 38fps in Borderlands 3 and 54fps in Horizon Zero Dawn when set to a 4K resolution. There is almost no gap in gaming performance when compared to less powerful processors, meaning that if you’re only looking to game on your PC, there are a lot of affordable options out there that will deliver similar if not equal performance as the i9-13900K.
The last gaming benchmark, Civilization VI, does not measure the same metric as the previous gaming benchmarks. This test measures how long (in seconds) it takes the AI to make calculations during loading times, instead of measuring the frame rate. The lower the number, the more efficient the processor is, as the AI is taking less time to make its move.
The Intel Core i9-13900K took 7.01 seconds to make its move, actually making it the slowest processor out of the selection we tested. The fastest was the AMD Ryzen 9 7950X, at 6.84 seconds, but the difference is so minor that you likely won’t even notice it.

Power consumption and temperature
- Runs pretty hot when in use
- Will eat up a lot of power
It’s important to consider how much power your PC will be consuming both while it’s sitting idle and under intensive workloads, so you can get a gauge of how it will affect your energy bills.
The idle power draw of the Intel Core i9-13900K is more intensive than its younger sibling. However, it came in with the lowest power compared to many of the AMD Ryzen 7000 Series, including the flagship Ryzen 9 7950X. This means that you won’t be guzzling up too much power while engaging in simple tasks or while it’s sitting idle.
It’s a bit of a different story when the Intel Core i9-13900K is in use, with the peak power draw coming out at 354W. This was a lot more intensive than the AMD Ryzen 9 7950X as well as its younger Intel Core i5 sibling, meaning that you will be consuming the most power while using this processor to play games or edit video.
The temperature of your processor will also have an impact on your PC, as not only will it determine how much headroom you have for overclocking, but it will have an impact on the type of cooling system you need to invest in.
While idle, the Intel Core i9-13900K hit 33°C, a middle-ground result when compared to the AMD and Intel chips listed above.
In the same vein as the peak power draw, the Intel Core i9-13900K ramped up during intensive tasks. The peak temperature hit 100°C, making it the hottest processor in this group test.
If your processor gets too hot consistently, it can do long-term damage to the CPU. This means that the Intel Core i9-13900K will need to be paired with a quality cooling system to ensure that the processor does not overheat.
