As I look at my aging C2 stepping PHII 965 I consider the things that I think need improving the most . I then speculate on what I would do if were charged with making an update to it.
Considering the things I do with it , I would concentrate on making it less power hungry, make it run cooler and improve the IMC to get the most from the ram that is currently available. As far as boosting pure computational power, I think for the time being , we may have reached a point of diminishing returns ( e-peen measuring activities being the exception). I'm quite happy with the day to day performance my current rig provides.
Given AMD's ability to innovate, I would expect a multitude of improvements ( that Intel will eventually emulate and with massive R&D will improve to a point beyond AMD's capability ) that would effect daily use with the upcoming release of Bulldozer. I'm also supremely confident that it will offer more "power" than I will actually use in 99% of the things I will use it for.
I expect it to provide value that will keep the competition's prices in check . I also expect innovations and performance that will keep motivating Intel to improve its product. As such, Bulldozer will be a win for everyone that uses these machines, no matter what brand you choose to purchase.
