CPU much slower on win 11
The title highlights the performance differences across operating systems. On Windows 10, the laptop handled video rendering at 3.5GHz with the Ryzen 4750U, but dropped to 2.34GHz on Windows 11—significantly slower. The thermal limits didn’t restrict it, yet the power slider disappeared, leaving it stuck in a balanced power plan without high-performance options. In Lenovo Vantage, the available power modes were also missing, leaving the user uncertain about how to restore the lost processing speed.
AMD and Microsoft released updates to address the issue... get both.
Ensure you have the most recent Windows 11 updates and AMD chipset drivers installed. Use the newest UEFI settings, though some systems may experience performance problems with FTPM enabled—this isn’t confirmed universally. Keeping the latest OS versions is beneficial, particularly when new releases are available.
It seems the cache issue might be resolved, but it’s unclear if this is connected to the reduced GHz or clock speed you’re experiencing. I’ve learned that AMD reported slower performance per clock in Windows 11, and you’re also noticing a drop in clock speed.
