I believe almost anyone, who has ever cared about performance of their laptop in the last 10 years has heard about undervolting. But if you have not, undervolting means to decrease the operating voltage of a component (in this case, CPU), which results in:
-Lower power consumption
-Lower operating temperature
-Better battery life
-and most importantly, higher performance.
As you see, it is a very nice feature to have, but unfortunately the option to undervolt has been completely removed without notice, in BIOS updates. For some it was possible to downgrade to the earlier BIOS, but people, who purchased their computer much later, or had their computer board replaced recently were not allowed to do so.
I have no idea why the option for undervolting would not be reintroduced as an option! I do not even see the reasoning behind completely removing it.
Was it for security? There is an option to disable all kinds of built in security: SGX, TXT, TPM, you name it. Does that make the user vulnerable to exploits? Perhaps. But they are choices. I'd prefer to have the performance I could set up earlier with an undervolt, stable, with no issues. I'd prefer to have a choice, and decide myself.
For example with a toggle, in BIOS. Like how there is an option to turn Intel Management Engine off, even though that causes loss of core functionality: it literally deactivates the complete onboard audio and rotation sensors on the HP Zbook Studio x360 G5.
What is the point of having the top of the line Intel CPU-s, whether it's 6 or 8 cores, if they thermal throttle to the point where they perform under specification? I would like to see my CPU perform better than it does now, while being 5-10 degrees Celsius cooler. I want it to perform how it already performed before. And I am not alone with that.
Within the mobile computing world it has been common knowledge for years, that with some minor voltage adjustments the performance and thermals of a computer can be improved, while decreasing the power consumption. We need the option in BIOS, a toggle, to allow adjustment to FIVR and voltage control again.
That is the option we are asking for - we want the better performing version of our laptop back.

Technology should move forward!
