yes CPU really works at 1.33GHz. What happens is this:
the operating system tries to save power by decreasing the processor clock rate. For that, it determines which clock rates are available, and selects the most appropriate one for the current load, according to the policy chosen by the user. The most conventional way of controlling the cpu frequency is through ACPI. Apparently in our machines ACPI reports the max available frequency of 1.33GHz, and, when the cpuspeed control is activated, it can't go beyond the max. Note that you're free not use CPU frequency adjustments, in which case you'll have your 1.66 back, at the price of shorter battery life. Windows can ignore the limit, or apply quirks, or not do any CPU frequency adjustments at all. What does powercfg /query report on your system? -- Atom N280 frequency scaling not supported https://bugs.launchpad.net/bugs/422858 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs -- universe-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/universe-bugs
