These articles will show charts made from data in articles. They're manually updated, so don't expect that new cards on site will show there. All values are theoretical and apply to reference models of cards. It's impossible for me add there various submodels like over/under clocked cards or with various memory bus width. Don't like empty article here, so we start with number of transistors chart.
Charts require flash. If you don't see them, then you can download image in attachments. Image can by also saved by right click - then Save/convert chart to image. Chart will be replaced by PNG image.
