Even the default ‘High Performance’ power plan is not immune. Intel moved core parking control onto the chip in the Skylake generation, and AMD followed, but still the parameters of the Windows power plans are set to aggressively park CPU cores. The aggressive core parking of Windows led to a great deal of inefficiency during bursting CPU loads. Initially, core parking was controlled entirely by the operating system. Unfortunately, this power saving comes at a price: Latency when CPUs need unparked to execute code. It dynamically disables CPU cores in an effort to conserve power when idle. Lifetime licenses are one-time payments for all future updates.ĬPU Parking is a low-power sleep state (C6) supported by most modern processors and operating systems. It'll also stay at a load if you've done anything like mess with the OC Genie/automatic overclock, changed vcore in bios, tampered with bios settings on a multitude of ways like disable speed step or c-states etc.Entire Home licenses allow installation on up to 5 PCs based in the same home. Moving the mouse is a load, so the cpu will not idle if you keep moving the mouse to keep the Screensaver disabled or the monitor active. OC will change that, as will locking the cores at max boost of 4.9GHz, both of which drastically increase power usage, and therefore heat output. For the 9700k, that's 1 core at 4.9GHz, 2 cores at 4.8GHz, 3-4 cores at 4.7GHz and 5-8 cores at 4.6GHz. It's usually pretty pathetic.Īt loads over 30% (which is basically anything you start up) the cpu goes to best performance mode and will turbo/boost according to temps and power limits. Idle, base, boost.Īt idle, the cpu backs off on core speeds and voltage use, so temps are set according to ambient case temps and efficiency of cooler.Īt minimal loads, under 30%, you get base speeds, which is the factory set speed to determine TDP.
