The Inq has written a new article about Intel's CSI and how it will perform versus AMD's HyperTransport.
Let us start out with the blunt reality, as defined now, CSI won't beat Hypertransport, and was not engineered to do so. OK, the architecture folk tried to engineer it to do so, but that version died a horrible early death, long before the Whitefield debacle.
CSI was started with a "mandate" to beat HT at everything, speed, bandwidth, per pin bandwidth, power usage, and everything else under the sun, not under Sun. From everything I heard, the engineers shot way too high, and achieved few if any of these goals. Hubris hit. So, what do you do in this case? Drink heavily and then start over.
