Well, it seems that AMD had the right idea with 64-bit and buying Ati:
- since they are in a cross-licensing with Intel, if Intel tries to revoke their x86 rights, Intel can't produce i7 (embedded RAM controller) nor Core2 (AMD64 = EM64T) anymore (not that Intel didn't try to have this agreement mitigated);
- since AMD+Ati make both CPUs and chipsets, they can sell a complete solution, even without making chipsets for Intel (Intel is probably counting on Poulsbo now and Larrabee in the future to remove the incentive on getting non-Intel chipsets with IGPs for Intel chips);
- since AMD started advertising complete platforms a while back, most of their chipsets are now made for their own chips (and as far as I know, they have none lined up for i5/i7), so they don't really care;
Seems to me that Intel's strategy is now also to promote fully Intel platforms, and as much as possible to revoke x86 licenses.
Lucky for us, AMD did force enough new tech on Intel to keep the market from becoming a de facto complete monopoly. Now all Nvidia could do, would be to buy an x86 maker and provide complete platforms too.
I wonder how much Via is worth, now...
