Difference for P and G

P45 was late getting out, because Intel's X48 rely more in performance. P45 chipset board with deliberately created lots of variants including a choice of several numbers from the P series chipset like the P43 type.

There is differences in P45 & P43. P43 only supports DDR3 memory up to 1066MHz, while the P45 supports DDR3 memory up to 1333Mhz.P45 can use dual VGA to VGA on a combination of a PCIe x16 or x8 PCIe VGA.

P45 & its variants mostly made for PCs with the cost of medium to low grade, is basically a board with a chipset type P has a cost lower than that of type X. Cheap cost with the P45 chipset can occur by reducing the feature board itself. If the board is more pricey usually added some features such as cooling method, overclocking features & several enhancements to make it more complete.

Chipset Type G (with integrated directly from the chipset internal VGA) version look a little different, targeting penguna who did not need a headache to choose VGA.

GMA X4500HD as internal built-in VGA with video acceleration, so as to display images movies with MPEG-2, VC-1 & AVC.

So far GMA X4500HD already supports HD format to 720p or 1080i but not 1080p.Intel said it also, GMA X4500HD already supports DirectX 10.

For the G43 will talk differently.

G43 has a capacity lower than the G45. Because it does not have a video decoding (that is when it is used to display images such as movies with HD formats), then the necessary capabilities of the processor. If you do not need a computer for screening, G43 could be an option because it is usually offered cheaper.

Both G43 & G45 already has a video output for HDMI ports, DVI & DisplayPort.So no longer needed outside controller chip & is integrated within the main chipset.
