Fabric Processors — Scale-Up & Scale-Out

The same programmable-fabric model, extended beyond the die: a scale-up processor for inside the rack and a scale-out processor for between racks — both with routing you can program.

The integration model doesn't change as you grow — up the rack, out the room, and across datacenters.
Two processors, one model

Up the rack, out the room.

Scale-up

Inside-rack fabric

UALink/NVLink-class connectivity — up to 1024×200 Gbps — for tightly-coupled accelerators.

Scale-out

Between-rack fabric

Ethernet/RDMA at 96×400 GbE for the broader cluster.

Programmable

Routing cores throughout

Distance- and congestion-aware policies in software, patchable in the field.
