CPU Performance Benchmarks
Now for the juicy part: benchmark results! We‘ll cover both processor performance in games and production workloads. All testing done at 1080p max settings to remove GPU bottlenecks.
Gaming FPS Benchmarks
First up, gaming frames per second. Higher FPS equals smoother, more responsive gameplay.
Wow, extremely tight results here! Both CPUs essentially match each other across these top titles. The Intel i9-10900K enjoys a few narrow wins in CounterStrike, GTA V and Call of Duty while AMD pulls ahead in Horizon Zero Dawn. But on average, less than a 2% performance difference separates them. Much closer than expected!
Conclusion: It‘s too close to call a definitive FPS winner. Both CPUs clearly pack enough gaming power to feed the fastest graphics cards. These differences come down to measurement variance.
Application Benchmarks
Next let‘s check multicore production workload performance with benchmarks like Cinebench, Blender and Handbrake:
Here the Ryzen 9 5900X leverages its beefier core count and cutting-edge efficiency to pull clearly ahead! Up to a 20% performance lead across the board is no joke. 12 swift Zen 3 cores defeats 10 of Intel‘s 14nm stalwarts.
