Intel goes out on a (rotten?) limb in efforts to catch AMD

[unixronin]

One of the reasons behind AMD's recent successes (read: taking away market share from Intel) in the server arena is its adoption of the HyperTransport high-speed interface for communication between multiple processors.  It is now reported that Intel, in an effort to reverse the loss of market share, plans to implement a similar feature on their own processors.

However, in what I personally consider a very ill-advised move, instead of adopting the tried, proven, and currently industry-standard¹ HyperTransport interface, Intel is inventing its own, which it calls CSI, for Common System Interface.  Intel makes quite a few showy-sounding statements about what CSI will do, but so far appears oddly silent on what it will do that HyperTransport doesn't -- apart, that is, from being a new, untested, untried, and undoubtedly initially buggy interface.

AMD, meanwhile, plans to move next year to HyperTransport 3.0, which will allow 41.6GB/s bandwidth, interconnects between up to 16 processors, and allows interconnects across multiple boards and even multiple chassis.

I don't know about you, but it sounds to me as though Intel's new Great White Hope is obsolete before it even gets off the drawing board.
