The Polling rate is typically measured in Hertz (Hz). For example, if one keyboard has a 1000Hz polling rate and the other has a 500Hz polling rate, then the first one sends the data 1000 times per second to the computer, whereas the latter one communicates 500 times per second. It’...
Clock rates are typically measured in hertz (Hz). One Hz is equal to one tick per second, 10 Hz equals 10 ticks per second, one GHz equals one billion ticks per second, and so on. A “tick” refers to the switch of a signal that turns on and off each time an action, task, or...
As a general rule of thumb, more is better for cooling; a CPU cooler that can handle 40% more TDP than your CPU's rating is preferred. However, having less cooling headroom won't prevent you from extracting any gains at all — the chip's peak temperatures will just limit how much you...
Clock speed, in the context of a CPU (Central Processing Unit), refers to the speed at which a processor executes instructions. It is measured in hertz (Hz), and commonly expressed in gigahertz (GHz), where one GHz equals one billion cycles per second. PC users overclock their hardware to...
The switching power supplies used today are much smaller and lighter. They convert the 60-Hertz (Hz, or cycles per second) current to a much higher frequency, meaning more cycles per second. This conversion enables a small, lightweight transformer in the power supply to do the actual voltage...
What Is a Keyboard Polling Rate? Keyboard polling rate determines how frequently your computer checks for key presses. Like many measurements with computers, polling rate is measured in Hertz (Hz), which tells us how many requests are made per second. As such, a higher figure means your compu...
Therefresh rate, stated in Hertz (Hz), or cycles per second, is how often the display—be it on a computer display, television, or tiny watch face—checks with its input to see if there’s something new it should be showing, and then subsequently…refreshes,to show that thing. This is...
The wavelength of light is the distance from one peak of the wave to the next. This relates to the wave's frequency, or the number of waves that pass a point in a given period of time. The frequency of light determines its color and is measured in cycles per second, or Hertz (Hz)...
A monitor’s refresh rate measures the number of times per second the screen can update with a new image. Measured in hertz (Hz), higher refresh rates translate to smoother motion and reduced blur. It also means that the monitor will be more responsive, with reduced input lag. ...
There's a good chance you have everything you need to dabble in the dark arts already and eke out a few more hertz from your gaming rig. If you're lucky, you may just be able to squeeze enough performance to stave off having to upgrade for another few months. Having said that, ...
