Let's accept as true AMD's explanation that the reason it doesn't want to release benchmarks for Barcelona is to limit Intel's ability to react. But doesn't that suggest that AMD believes that Intel's chips have the capacity to, if not match, at least get pretty close to the performance of Barcelona? I believe AMD when it says K10 outperforms Core 2 but I don't think AMD is worried about Core 2, it's worried about Penryn. I think one reason Intel was so free with Core 2 info was that it knew AMD simply COULDN'T react. I think AMD's secrecy with Barcelona benchmarks betrays its own belief that Intel can push Penryn hard enough to put up a good fight with Barcelona. That's not exactly encouraging for AMD and it makes me doubt whether Barcelona will give AMD the breathing room to get its bearings again.
Will Penryn be clocked over 5ghz...? No 4.5Ghz No, 4.1ghz NO. ... Will 50%+ over C2Q be reached with Penryn at 3.2ghz vs 3ghz C2Q? No (Problem? YES)... Will a 2.5ghz K10 be 50% faster then C2Q at 3ghz? Yes. Will intel need a 5.5ghz Penryn to counter a 2.5ghz K10 effectively? (5Ghz+ is needed to make a over 50% performance advantage valid) YES YES YES. Don't forget K10 also has SSE4a you know. Intel doesn't have any instruction set advantages.
"besides Hi-K Metal gates witch is a process that makes transistors faster also reduces leakage and makes lower powered cpus sure thats what they are talking about they will have better performance at lower watts wile getting a higher MHZ speed, that has nothing to do with its true performance, It will perform only slightly better performance to performance with a C2Q, the CPU's cycles per clock will hardly be effected only by instruction set tweeks (Just like AMD's), maybe with MHZ ups but thats about it with lower watts and heat. Sorry. Penryn only gets a instruction set boost that make it appear faster when its only just been tweaked. Its just a die smirk really with some fancy words that give it a higher performance per watt factor not a real difference besides the SSE4i add on. AMD has the same thing.)
