Understand that CSI is "speculative cache coherency." It's game changing. I don't know if anyone has ever tried anything like this before. Certainly not in the x86 space. What Intel is doing is going ahead and using a cache line before knowing absolutely for sure that using it does not create the possibility of an incorrect result. In the rare instance where there turns out to be a problem, they have to back up. The result is much better latency at the cost of much greater complexity. I believe that AMD has been right for these many years. "It's all about latency." Somehow, Intel has managed to make C2D perform better than AMD's parts by a combination of better core design, larger caches and better process parameters. All of this in spite of worse latency. But now, latency is going to turn into an Intel advantage. When that happens, look out.
