Generally, larger numbers denote better performance. Within a generation of graphics cards this is easy to understand. It is obvious that the GTX 780 will perform better than the GTX 760, and that the R9 280X is faster than the R9 270. But how does the GTX 680 compare to the GTX 760? And the HD 6950 to the HD 7790? At first glance the performance of these two cards might not be easily discernible. NVIDIA NVIDIA’s card names look like this: GT 610, GT 620, GT 630, GT 640, GTX 650, GTX 650 Ti, GTX 650 Ti Boost, GTX 660, GTX 660 Ti.
