Velocità Memoria = frequenza DDR raddoppiata, quella fisica è la metà
Velocità di clock DDR5 quadruplicata rispetto a quella fisica
SPs = stream processors; P and V = Pixel shader and Vertex shader
TC = Turbo Cache
HM = Hyper Memory
OC = Overcloccata (clock più alto di quello predefinito)
SLI = Operazione in parallelo con 2 schede nVidia
3 SLI = Operazione in parallelo con 3 schede nVidia
4 SLI = Operazione in parallelo con 4 schede nVidia
CF = Operazione in parallelo Crossfire con 2 schede ATI
3 CF = Operazione in parallelo Crossfire con 3 schede ATI
4 CF = Operazione in parallelo Crossfire con 4 schede ATI
R680 = 2x RV670
Shader 2.0 = DirectX 9.0; 3.0 = DirectX 9.0c; 4.0 = DirectX 10; Shader 4.1 = DirectX 10.1
