補充一下！取自Extremetech中後段的重點！

Also new is an enhanced version of AMD's PowerNow. Previously, PowerNow would allow the CPU to reduce its frequency as needed, on a per-socket basis. Barcelona will allow individual core frequencies to lower while other cores may be running full bore. Note that voltages will not change on a per core basis, but lowering the frequency should still help with heat generation.

AMD estimates that the power consumption of a Barcelona will fit within a 95W envelope. An example cited for a two-socket system, plus memory, plus the chipset, is estimated at about 240W (not counting graphics and storage.)

意思好像是K8L四核心使用中！允許某些核心閒置時採用降頻方式來節能和降溫！而其他核心仍然可以以全速去執行程式！而且功耗是控制在95w的範圍以內！
