What people are comparing is IPC, and for that Phenom and Barcelona are identical in architecture and memory timings will make AT BEST only a 1-2% improvement. So no, Phenom = Barcelona for these comparisons.
Actually, before C2D, SuperPi was one of THE AMD benchmarks. Netburst got creamed in Super Pi.While I agree with you, I'd like to point out that all these tests are ran with BA/B1 revisions. B2 should be better. AMD has never been better or faster than Intel, especially not in SuperPI alike (has there ever been ANY 1M world record made with AMD CPU?), which people like to use as a "speed-o-meter".
K8s were never THAT slow to begin with. Over the span of 3 years, the different revisions only added MAYBE 8-10% TOTAL improvement over those 3 years (and most of that came in the one step of going to a dual memory bus on Socket 939). How many revisions since the E4/E6 cores have shown IPC improvements? None. And Brisbane was actually a small step BACKWARDS.Remember how the first K8's were? SLOW, at least when compared what they were with S939, so there was quite an improvement there, and I wouldn't be surprised if they managed to make it again. At this point I have to say that I have no clue what kind of improvement has Intel made since C2D launch, so even if AMD can improve, is the improvement enough to fight Intel?
Only partially true. Quad and Tri-cores come from the same wafers. Dual cores are a completely different entity and are made as dual cores to start with.AMD can always TRY to fight with price, but it won't be so good for them, bad yeilds and cheap prices, need to say more? Though, if I understood correctly, AMD makes the chips always a full X4, and then if the yeild was good, it will be sold as X4, if one core is danaged, it will be sold as X3, if half the die is damaged (2 cores) it will be sold as X2 and so on.
Intel is not stupid enough to be paying anyone SQUAT right now (or for the past 18 months). They are in the middle of being investigated for this in multiple countries. I'm sure they are walking the "straight and narrow" right now. After the investigation, who knows. But you can bet they are playing nice right now (well, except for the fact the C2D is kicking everythings arse).Also as I said in other thread, AMD is pretty much screwed, it can't really sell alot since Intel just pays resellers not to sell AMD, which it did for a great time. All hail corruption.
