We had a chance to take a look at Intel's latest roadmap and for the first time we see the P31 in it. This is nothing more than a variation of the entry level G31 chipset without integrated graphics.
It will come in Q3 2007 and it will support Core 2 Duo, Quad and the upcoming Yorkfield and Wolfdale 45 nanometre processors.
It support 1,333Mhz FSB, but only from Q1 2008 as Intel is still doing some validation. It will support DDR 2 800 and ICH7, ICH7R and ICH7DH.
