This is certainly a very interesting situation. I am expecting it to perform within 10% at most of 850, and even maybe 5%. But the question is will there be good boards, and yes I think a company in Taiwan is gonna bite and produce a P4X266 board. The major issue, is will Intel fight back Leagally? I really couldn't tell you, There's 3 sides to this as far as Intel's concerned,
1. The P4 department are welcome to a low cost chipset, using low cost RAM, that may perform just as well as 850 is going to be in the market.
2. The chipset department doesn't want to surrender more to VIA, they want to release 845 DDR but they can't because of the Rambus agreement.
3. The head exec wants to give the nod to relase 845 DDR but then Rambus will get mad.
So needless to say, Intels' in a rough position. Personally, after what Craig Barrett said a week ago about not caring about Rambus dieing or not, I will not be suprised to see them go ahead and release 845 DDR, now will they still hit VIA with the P4 bus license, I dunno. P4X266 is still gonna be cheaper than even 845, so it should be interesting. But in any case, I think P4X266 is gonna rock, if it's not hurt by compatibility issues.
