After demoing its capabilities, Intel is now selling the world’s first 6GHz desktop processor, the Core i9-13900KS, but at a pricey $699. 

On Thursday, the company launched the CPU, which can reach a 6GHz boost speed out of the box, without any overclocking. Earlier this week, Intel published a brief video on the chip’s capabilities, showing that it can reach a 5.98GHz frequency speed. 

The catch is that the chip can only sustain the speeds for short bursts lasting a few seconds, and only over two performance cores, based on the video. Still, the 6GHz speeds promise to elevate the product as perhaps the fastest desktop CPU on the market. 

“The unlocked i9-13900KS processor represents a major milestone in the PC industry —bringing faster speeds than before to enthusiast desktop users,” Intel added. 

The i9-13900KS is like the $589 Core i9-13900K—which can hit 5.8GHz boost speeds—in that both have eight performance cores and 16 efficiency cores for a total of 24. However, the KS version features slightly higher base and boost clock speeds across all cores, based on the spec sheet

In addition, the KS chip has a higher base power requirement at 150 watts over 125 watts, although the max power requirement for both chips is the same at 253 watts. The Core i9-13900KS also arrives unlocked, meaning users can overclock the PC to even higher frequency speeds, but it’s best to do so only if you have powerful cooling system installed over the CPU. 

Stay tuned for our review when we can really put the CPU to the test. In the meantime, Newegg is selling the chip, but at the higher price point at $729 while B&H Photo and Video is offering it for $749. The chip is compatible with both Z790 and Z690 motherboards.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
