Ok, I lied, Intel Spoils the Party. Rumored Intel Price Cuts
At the end of last year Intel made some minor price cuts across its product lineup. There was no reason to do anything more serious as AMD hadn't even begun to threaten anything above the Core 2 Quad Q6600.
I've heard, through reliable but very quiet channels, that before the end of January Intel will aggressively cut prices on its entire quad-core lineup. Given how Intel historically cuts prices, we could expect the Core 2 Quad Q9550 would take the place of the Q9400 and have the Q9400 move down to the price point of the Q8300, thus creating a price war; and you thought 2008 was the last of that.
If Intel were to push its prices down like that, the Q9550 would compete with the Phenom II X4 940, and the Core 2 Quad Q9400 would go up against the Phenom II X4 920 instead. If this happens, the conclusion I mentioned on the first page changes. The Phenom II X4 940 can't beat the Q9550, and the 920 can't beat the Q9400. Intel has the ability to do this; it's got faster chips that are more expensive and has just enjoyed 2+ years of unchallenged competition. The Intel from the Pentium 4 days may have let AMD launch Phenom II unchecked, but today's Intel is much more...dynamic.
The take away is that today Phenom II competes with the Q9400 and the Q8300, but by the end of this month that may change to the Q9550 and Q9400.
