How much L1 cache you have depends on your processor. Most Pentium II chips will have a 512K cache. The new Celeron CPUs have either a 0K or 128K L1 cache. Video RAM Besides the RAM it uses for basic processing operations, your computer also needs a couple other types of memory. Your video card, for example, has its own memory.
Video memory is used to store image data for processing by the video adapter.
The more memory an adapter has, the higher quality of image can be displayed. You can figure out your minimum video memory requirements by multiplying the total number of pixels on your screen by the color depth you want. Your video image is composed of a set number of dots, or pixels. The total number of pixels you see is calculated by multiplying width by height, e.g. , an 800 by 600 image has 480,000 pixels. Each pixel occupies a certain amount of video memory.
