  • Powerful enough to power through pretty much any workload
  • Great CPU performance for the price
  • Only 8 cores in Rocket Lake's Core i9-11900K


The Intel Core i9-11900K is the flagship desktop processor in Team Blue's new Rocket Lake-S range. Intel backported the 10nm Ice Lake architecture to a 14nm process, which is the core reason why it's back down to an 8-core, 16-thread design. The new Cypress Cove core does allow Intel to push clock speeds slightly higher – up to 5.3GHz on a single core – but also allows for a 19% boost in Instructions Per Cycle (IPC) performance.
This rundown provides our analysis on 8 third-party reviews. The sentiment scores, summaries, and key takeaways that we select are based on these reviews and may differ from the original publication.

Rocket Lake is the last lap for Intel's aging 14nm manufacturing process, first introduced in 2014. We tested Rocket Lake-S, specifically the8-core Core i9-11900K, against its 10th-gen predecessor and its arch-rival. The vast majority of 3D modelling used to create those amazing cinematic visual effects you see in movies today run faster on systems with more cores.

  • Great performance for a 14nm CPU
  • Improved 3D modelling engine
  • Better CPU performance than its predecessor
  • Lacks Resizable BAR option for both Intel boards


Sentiment Score[*] 80%
Reviewers from Techradar have found the following[***]:
The Intel Core i9-11900K comes as Intel struggles to hold on to relevance in the desktop market. While it does mean that the processor has extremely strong single-core performance, it falls so far behind in multi-core that it's definitely not worth the sticker price. With rumors that Intel's 12th-generation Alder Lake-S processors could arrive as soon as September 2021, it feels more like a stopgap than something to get really excited about.

  • Powerful single-core performance
  • Strong multi-core and multi-thread performance
  • Nothing in particular
