Chipsets
There's a slew of new motherboard chipsets, too, dubbed GM45, GM47 or PM45. The GM45 and GM47 both have a high-speed 1,066MHz front side bus -- basically a lightning-quick highway for transferring data between the memory and the CPU -- and will support DDR2 and -- for the first time -- DDR3 memory, which has a higher peak throughput than previous memory technologies.
Both chipsets will feature Intel's new X4500 HD integrated graphics adaptor, which has integrated HDMI and DisplayPort. Both are also DirectX 10-compliant, but if games are important to you, opt for the GM47, since that has a slightly faster graphics core -- 640MHz versus 533MHz.
The
aforementioned PM45 chipset supports all the same features, but lacks
an integrated graphics adaptor. It'll therefore be the chipset of
choice for high-end gaming laptops, and will come with either ATI or
Nvidia graphics solutions.
