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.
