You've tested your Ryzen 7 5800X against your older 3800X and found a small performance gap. The new chip caps at 4.2GHz while the previous model could reach up to 4.7GHz. Online suggestions like Precision Boost Overdrive haven't helped so far. Checking system tools such as Windows 11 Task Manager, your motherboard BIOS, and CPU monitoring apps confirms the same limit. Consider updating BIOS, ensuring your drivers are current, or exploring firmware tweaks to unlock higher speeds.

Maximum speed boosts are usually single-core. You’ll notice this only when a single core is employed. Every core boost will be reduced.

I'm testing the benchmark displayed in the screenshot as a single-core execution. I've reviewed videos where the same CPU operates at 4.5GHz to 4.7GHz during a multi-core task. While AMD's site mentions the maximum boost clock matches the peak frequency for a single core on a bursty workload, that doesn't clarify why the speed is limited to 4.2GHz instead of higher values like 3.8GHz or 4.7GHz around the 4:00 point. Edit: this still lacks a clear explanation. — HeathenMFG Added November 2, 2023

Verify temperatures; low cooling might be the cause. Look in Task Manager for other cores near idle during the test.

What cooling options do you have? What are the temperatures? Is your motherboard equipped with enough VRMs and adequate cooling? Even with PBO it may not achieve full performance if your board lacks strong power delivery. The 5800X and its similar model require around 120W just to hit their base boost speeds. For overclocking, such as aiming for a 4.7 GHz, you’ll need more power. If you didn’t get the right chipset, it might struggle to reach that speed.

Task manager indicates it's executing the benchmark on the 8th core while other cores remain unchanged. Performance metrics stay stable across both single and multi-core conditions, with peak temperatures reaching 52 and 58 degrees respectively.

I concur with the others' opinions. Consider downloading HWinfo64 and operate sensors only during cinebench runs for 10 minutes. Clocks should align closely if temperatures are favorable: https://www.techpowerup.com/review/amd-r...0x/21.html

The processor features a water cooling system with a 360mm radiator. It runs on an Asus ROG Strix B550-A motherboard, which should provide sufficient power to achieve close to its peak boost frequency. Temperatures remain within normal ranges.

True. The AMD Ryzen 7 5800X delivers 175W at maximum capacity.

The graphs illustrate how the processors increase their clock speed to the expected level. Your system is limited to a maximum of 4.2GHz and remains unchanged on that core clock. On the website, CPU-Z displays a boost clock of 4.6GHz, whereas your system reports 4.2GHz.
