1. GPU / Chipset
GPU / Chipset is a unit that process the graphic in a computer. So, your computer will not burden by task that related with graphic. What type used give impact to some important things such as Core Clock Speed, Memory Clock Speed, and Ramdac Clock Speed. But don’t judge the quality of Video Card only from what chipset they has. Maybe you can see about review about their performance and compare it.
2. Core Clock
Core Clock is speed that video card has ( how many times processor graphic adapter can rotate in one second ). That’s why it represent in Mhz. So, higher Core Clock will provide the faster work that graphic card done.
3. Memory Clock
Memory Clock is speed that RAM on graphic card can transfer data from or to video card processor. Faster Memory Clock will provide the faster graphic process.
4. RAMDAC ( Random Access Memory Digital to Analog Converter )
RAMDAC is speed that video card has to convert data from digital to analog and than will show on monitor. RAMDAC will give effect on refresh rate that video card has.
5. RAM
Video card also need RAM to make temporary save when data processing. More complex graphic process will need bigger RAM. When you hear “VGA Onbard” that mean your graphic process will take RAM from your computer. In other words, the video card doesn’t has their own RAM. You also need to pay attention on bits value that RAM has. Bits is how many data that RAM can send in one Memory Clock ( rotation ).
