Well, yes and no. I don't see how CAT can differentiate between a packet header and packet data, but being able to control the number of ways dedicated to DDIO

Well, yes and no. I don't see how CAT can differentiate between a packet header and packet data, but being able to control the number of ways dedicated to DDIO would be nice. In terms of features like CAT being available on different SKUs.. Intel needs to remember that they're not just competing with themselves these days. Their competitors generally don't go fusing off features on low-end SKUs to drive sales of higher margin SKUs. Intel needs to differentiate chips solely on on cores count, clock speed, cache size, etc.
