This is an NPU, so for sure not in the 5k, or any other Nexus. Those are all fixed-function ASICs, in some cases (like the 3k, or the 5k's L3 module) actually Broadcom ASICs. The original 5k (which was a Nuova Systems product before cisco spun them in), had a 1040G crossbar (nicknamed Altos) and a bunch of 80G line chips (nicknamed Gatos).
