PHC03 @ 14 nm · 64-core 1U server node — PhantasmPhi CPU

A chip should earn its place in a rack the way a person earns a seat at a table: by doing the work, not by being talked about. This edition is PhantomCore at rack scale. The name says PHC03 at 14 nm, a 64-core 1U server node; the description says sixty-four PhantasmPhi cores at 1 GHz in a one-rack-unit box. It is RTL-proven, so the logic has been exercised and holds, and it is SKY130-mapped, so it has been carried onto a named open process rather than left as a drawing.

One rack unit is the thinnest slice a datacenter hands out, and sixty-four cores in that slice at a gigahertz is a part built for the hall, not the bench. It is for the datacenter operator who buys servers by the row and wants a CPU with a blueprint behind it before it goes in, for the engineering buyer specifying the next node, and for the licensee who wants a server-class core they do not have to take on trust. The figures behind it are laid out in the full calculator on the site; this is product number 10329, the rack-scale edition.

What you walk away with is the use of the blueprint for this 64-core 1U edition. The PhantomCore design stays with the inventor, CRI-ONE; the right to fill a rack with it is yours.
