How the lists work
Each list starts from every part in our database, keeps the ones that match a filter (a brand, a socket, a price limit or a memory size) and ranks them by our performance index. The first row is the fastest part that passes the filter. A second figure, index points per $100 of launch price, shows which part gives the most speed for the money.
The index is our own estimate of gaming performance. It is good for telling a fast part from a slow one and not for telling two close parts apart, because two parts within about 5% of each other can swap places in a game.
