I know that, in my first post I said "I think" (not that "I know), and went on to state why, which is because AMD is 1-1.5 years behind right now on their processors. I don't see AMD leaping forward that far.
I understand you that you guys are saying its a new architecture, but even a new architecture might not make up that much ground. We'll just have to see I guess.
I want Bulldozer to beat Intel as bad as the rest of you, competition is great, but I'm just trying to be realistic about it's chances to beat Sandy Bridge.
I think a lot of us who regularly follow AMD and use their CPUs are being realistic about what bulldozer will bring to the table. Even in this thread, I have seen more reasonable posts about bulldozer than "it's going to plow right through Sandy" type posts.
The tricky part is the "beat" does not have the same meaning for everybody. I am somewhat confident that when released that the 8 core bulldozer will the the fastest chip (slightly besting the the mighty 990x) when handling encoding, rendering, and other types of workloads that benefit from multiple cores. I am also fairly certain that Sandy Bridge will be able to get through a single threaded workload at least 5%-10% faster than bulldozer (making bulldozer equal to about Nehalem IPC).
It really depends on how you use your PC. Personally, I am a gamer. But do I really need the little boast in IPC that Sandy will likely bring? Most people agree that a i7 920 at 4GHz won't bottleneck a SLI/CFX system unless the games is very CPU limited or your frame rate is well into the 100s. Meaning that even if bulldozer doesn't "beat" but lags 10% behind Sandy in IPC there won't really be any difference in games.
With that said, however, I am sure that there are some people who must have the best single threaded performance available. Of course, there are others value more cores and overall processor throughput which is where AMD should shine.
The one thing I do know for 100% certainty is that even though it is impossible to determine... once released there will be a big argument about which company "won".
