TCC == Thermal Control Circuit, special circuit found in p4 CPUs, which allows to control processor trottling, effectively controlling power consumption and performance. Usually is controlled automatically to prevent CPU overheating, but it is possible to control it from software. ESS == Enhanced Speed Step, special technology in Centrino CPUs, which allows to control frequency at which CPU runs again to control power consumption and performance. -MaximReceived on Wed Aug 18 2004 - 10:22:28 UTC
