There’s more to graphics than a sticker on your computer

Lately, computer makers have been tagging stickers on their computers to boast about the AMD or NVIDIA graphics components they have included in their computers. Unfortunately, those mean thousands of different things, and it’s pretty hard to tell just what.
Basic: If you just want to know whether the card in the computer on the left is better than the one in the computer on the right, you can do a quick search on for the graphics components in each. Some buzz words to be aware of are “integrated” and “dedicated.” The former is built into the computer’s processor and relies on the computer’s memory — typically this is a lower performance graphics component. A dedicated graphics card will include its own processor and memory and they tend to be higher performing — though a very old card might not best modern integrated graphics.
Advanced: If you’re looking into the specifics of graphics processors, you will have to think of them like their own pair of a processor and RAM. This is another case of the more, the merrier. Higher speed, higher capacity RAM in the graphics card will let it handle a more intense graphic load and do it quicker. This will allow for better, more fluid visuals. The cards processor speed will be similarly important and can be looked at much the same as a computer’s processor. You can dig into the details and see how many shaders it has and what its core speed is, but in the end it will probably be most valuable to check out a benchmark score that has evaluated its actual performance.
