HyperTransport and Intel QuickPath isn't chiplet technology.

AMD "upgraded" HyperTransport to Infinity Fabric. Which IIRC uses a bit less power (taking advantage of the shorter, more efficient die-to-die interposer).

Intel has UPI (upgrade over Intel QuickPath), but it hasn't been "shrunk" to chiplet level yet. Intel has EMIB as a physical technology to connect chiplets together... but Intel still needs to create dies and a lower-power protocol for interposer (or maybe EMIB-based) communications.

So Intel has a lot of the technology ready to create a chiplet (like AMD's Zeppelin dies). But Intel wasn't gunning for chiplets as hard as AMD was. Still, Intel demonstrated their chiplet prowess with the Xeon+FPGA over EMIB. So Intel definitely "can" do the chiplet thing, they just are a little bit behind AMD for now.
