AMD's 5600X Chip Claims Top Score in Single-Threaded Performance

The $299 chip scored a 3,495 on Passmark’s test, which is about 10 percent higher than the runner-up, Intel’s $549 Core i9-10900K processor.

One of AMD’s newest chips, the $299 Ryzen 5 5600X, has beat Intel’s competing processors to take the crown on PassMark’s test for fastest single-threaded performance. 

PassMark previously rated 19 Intel products—from the Core i7-10700F to the i9-10900K—as the top performing chips on single-threaded performance. But on Thursday, the benchmarking provider updated the list to show the upcoming Ryzen 5 5600X as the top dog. 

“We have a new leader in the single threaded CPU benchmark chart. The AMD Ryzen 5 5600X,” Passmark announced on Twitter, which was later reported by VideoCardz.

Indeed, based on the benchmarks, the chip scored a 3,495 on Passmark’s test, which is about 10 percent higher than the runner-up, Intel’s Core i9-10900K, a product that currently retails for $549 and has 10 cores. In contrast, the 5600X only has six cores.  

The AMD processor also scored about 30 percent higher than the previous generation chip, the Ryzen 5 3600X

That said, the benchmark for the Ryzen 5600X was only based on a single sample of the processor. So expect the score to change in the coming weeks as more 5600X units enter the hands of actual consumers. 

PassMark also tested the Ryzen 5600X while taking into account the multi-threaded performance. The resulting score ranked the product close to last year's AMD Ryzen 7 3700X, and ahead of Intel's Core i9-9900K, both of which are eight-core chips.

Still, the PassMark benchmark was only performed on the lowest end Ryzen 5000 processor—not the rest of the pack. Alongside the 5600X, AMD is releasing three other chips, which have more cores and higher clock speeds: the Ryzen 7 5800X, the Ryzen 9 5900x, and the Ryzen 9 5950X. So expect to see higher PassMark scores from AMD products in the near future.

If the benchmark for the Ryzen 5600X is legit, then AMD wasn’t kidding when it said the new processors would deliver leading performance on single-threaded tasks. In the past, AMD chips have generally lagged behind Intel’s competing processors when it comes to gaming performance, which can lean heavily on the CPU. However, AMD claims the upcoming Ryzen 5000 series chips have been redesigned for higher instructions per clock while reducing the latency. 

As a result, AMD’s new processors may seriously shake up Intel’s long-held dominance over the PC gaming market. The Ryzen 5000-series chips will go on sale Nov. 5; stay tuned for PCMag's reviews. 

As for PassMark, it’s important to note the company’s rankings on single-threaded performance can drastically shift. Back in February, AMD’s processors originally held the top spots. However, in March PassMark changed the way it scored single-threaded performance for better accuracy, which elevated Intel’s processors to the top of the pack.

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.
