Conclusion 
Average Bench 93.2%
Average Bench 85.1%

My favorite CPU of all time after the Core i3-8100 that I upgraded it from, to this, the amazing Core i5-9600KF, that has no problem being soft overclocked to 4.8 GHz on all cores with no stability or heat issues. I just love it and I have been using and don't plan on upgrading it anytime soon. What a beast! [Jun '23 therealmustii]

MORE DETAILS

Released 25 November 2019, this Cascade Lake-X CPU is the refresh of i9-9900X. What got improved is pricing which is almost the half of the mentioned CPU and some mitigation against silicon and hardware level vulnerabilities. This CPU got improved base clock and boost clock, with each having 200MHz and 100MHz higher clock respectively. [Dec '19 ColdSpy]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
