Intel i865 chipset
will come as
i865P:
800FSB and 533FSB support (prescott ready), DCDDR 400 and 333 8x AGP
The onboard network will not use the PCI bus but rathre have it own called "Communications Streaming Architecture (CSA) bus" with 2GB/s bandwidth
Will use the ICH5 south bridge
i865P:
Same as i865PE minus 800FSB support (prescott)
Will have 400FSB unlike i865PE and will support DCDRR 266 and 333
i865G:
Same as the i865PE but with intregrated Graphics
Q2 like the others said is when we should see the product lanuch.. along with Canterwood, i875 later in the same quater.
i875 is targeted at the high end, should have better memory bandwidth and lower latency. Will also have ECC support
