Geforce 9400/9300 & Hybrid SLI versus Intel G45
 

The new chips of the Geforce family are integrated graphics processors. Both, the Geforce 9300 and the Geforce 9400 don't have dedicated video memory. Therefore they have to use a part of the system memory (512 MiByte at max) to store their data. DDR2 800 and DDR3 1333 are supported - the motherboard producer decides which kind is used. For our tests we used a 512 MiByte framebuffer.

The only difference between the 9400 and the 9300 is that they have different clock speeds: The latter one runs a t 450/1,200 MHz and the other one at 580/1,400. The calculating units are the same for both cards: 16 Shader ALUs (4 Vec4) and four texture units.
