Gigahertz (Ghz)s the measurement for the speed of a computer. 1 Gigahertz is equal to 1000 Megahertz or 1,000,000,000 Hz. We commonly use Ghz because it's easy to pronunce like 2 GHZ rather than 2,000 MHz . Gigahertz can also be applied to CPU speed or Ram Speed or other hardware's speed. But comparing CPU to CPU Speed is not alwats acccurate, remember different architecture doesn't it mean the other processor is faster than the other company's processor (see INTEL & AMD competition), but comparing the GHZ speed on the same series , can make a huge impact to computation speed, pentium IV (3.0Ghz) is greater than pentium III (1.2 Ghz)
Graphic Cards (Sometimes called Videocard) are expansion devices usually inserted on PCI, AGP or PCI-EXPRESS motherboards. It's main purpose is to produce good quality graphics for rendering, especially on gaming. PCI and AGP are legacy slots, we commonly use PCI EXPRESS as the commonly use slot for our Graphics Card. The Graphic Cards acts like CPU but it specialize in graphic intensive processing. The Graphic Cards can be categorize it's memory speed like DDR2, DDR3 or GDDR5 or it's memory bandwidth 64 bit, 128 bit or 256 bit or more , the higher this memory and bandwidth the faster the card is. It has GPU(Graphic Processing Unit similar to CPU) that encase with shroud or aluminum metal use to protect and cool of the GPU processor of Graphic Cards.
