And it will. I for one won't buy a 64-bit processor if I can only use 32-bits.
But what if that processor has a better price/performance ratio in 32 bit applications than the competition? Hammer should continue to go toe to toe with Intel processors for performance in the regular 32 bit applications we use today. It just boasts the added benefit of even greater performance when using 64 applications.
I think the real key is that the Hammer doesn't "lack" when it comes to 32 bit performance. If it does, AMD is in big trouble. Migration to a new OS platform is something that happens cyclically every few years. Even if MS exclusively goes to releasing 64 bit Operating Systems by the end of the year (which obviously it won't), it would take several years for such 64 bit based OS's to become the majority platform in the market. AMD is going 100% Hammer focused for it's top end processor by the end of the year! It MUST stand up to Intel performance in the 32 bit world. The 64 bit boost built in to the same small package should just be icing on the cake.
My personal belief is that Intel will be able to pass AMD in 32 bit performance shortly after the Hammer is released - but AMD won't let that gap be significant and will show a significant performance boost with 64 bit software.
Getting good support from Microsoft could mean the difference between standing still or even slipping in market share vs. having a killer product that is widely embraced as another 'Product of the Year' and continues AMD's growth in the processor market.
