If slashing 50% off your entire top end Nehalems isn't "going into a price war", what is? Fact is, the people who buy enthusiast cpu's realised that AMD's 6 cores beat intels quads, so intel had to slash prices while AMD's never dropped. It's simple economics, your theory is laughable.
My theory is laughable? Lets look back at history shall we? When AMD released the Athlon 64, it became a hit. It ran at lower clock speeds and lower thermals but beat Intels Pentium 4. FOrward to Pentium D and Athlon 64 X2. Same thing.
SO lets also look at the pricing. During that time, AMD was able to sell its chips at such a fast rate, that they couldn't fill the needs of large OEMs let alone their loyal small OEMs (who they stiffed quite a bit to sell to the big OEMs). They put a large premium on their CPUs. Their top tier CPUs hit $1K+.
Intel released their Core 2 CPUs and took back the performance crown. It took AMD about a year to start dropping the price.
But what that shows is that whatever AMDs CPUs perform next to, is what they will price it at. If Thuban performed as well as Gulftown then Thuban would be near $1K. But since a 6 core Thuban can barley beat a Core i7 920 at a higher clock speed in everything but insanley highly threaded optimized applications, and even then it sometimes doesn't do much better, they had to price it near the mid end Core i7 and lower range in prices.
If Intel kept their CPUs at the same price or lowered them constantly, AMD wouldn't survive.
We can go back to the first set of quad cores from Intel. The Q6600 hit pretty high but even before AMD released their first quad core, it was sub $300.
Believe me when I say that if Intel wanted to do a price war, you would know it and AMD would be hurting.
