NVIDIA GeForce 9300M G
Enhanced 8400M GS chip, which is manufactured in 65nm and shows slightly better performance due to a few minor optimizations. The technical data correspond to the 8400M GS chip.
A particularity of the graphic card are the "Unified Shaders" or ALUs (Arithmetic Logical Unit). There don't exist any dedicated pixel- or vertex shaders but 16 so called stream processors make the graphic tasks. The advantage is that theoretically there don't exist idle time of the ALUs. The NVIDIA stream processors are 1-dimensional (1D) and are able to accomplish one skalar operation with one MADD-operation (addition and multiplication). Moreover, NVIDIA clocks the shader ALUs somewhat higher than the rest of the chip.
An advantage of the GeForce 9000 series is the integrated PureVideo HD videoprocessor. It helps with the decoding of H.264-, VC-1-, MPEG2- and WMV9 video material in HD quality and therefore reduces the CPU load.
Probably, the memory clock of the GeForce 9300M G depends on the used memory type: 400 MHz with GDDR2 and 600 MHz with GDDR3 were used in 8400M cards.
