Your i9 9900 is functioning normally, reaching up to 5GHz on all cores. It’s not indicating a CPU issue.
Benji's analysis is accurate. The single-core performance will shift between cores. The i9-9900 exhibits the following Turbo Boost settings: 1 to 2 cores on, reaching up to 4.9 GHz; 3 cores active, up to 4.8 GHz; 4 to 5 cores active, up to 4.7 GHz; 6 to 7 cores active, up to 4.6 GHz. When you captured the screenshot, the CPU was idle and operating near 0.8 GHz, which aligns with typical i9-9900 behavior.
