InterTwined

CSI isn't here, though, and it won't be here this year either. Intel's next-generation x86 processors are therefore stuck with an antiquated, shared-bus interconnect topology that's bandwidth-starved, expensive, not scalable, and inferior to coherent HT in every respect.
This is bad news for those of us who're pumped about Merom/Conroe, because—as any Apple fan who uses a G4 can tell you—you can have the baddest processor on the market, but if you're starving it by sticking it on an outdated FSB then a lot of potential performance is going to waste.
In 2006, AMD will no longer be sitting on a processor architecture that's superior to Intel, but they will be sitting on a processor interconnect technology that's miles ahead of what Intel is offering.
