PCIe retimers and CXL connectivity — the glue chips inside every AI rack.
Plate I — Pillar-Purity Score
10/ 10
Zero non-AI revenue. Pure-play.
Methodology — How we score
Plate II — The Thesis
Why it’s on the list.
Astera's retimers and CXL controllers are the tiny but mandatory chips that extend PCIe signals inside every AI server. Pure-play AI-rack connectivity — no legacy drag.
Plate III — Supply Chain
Upstream & downstream.
See the full chain plate for all 37 names.
Upstream — what feeds ALAB
Downstream — where ALAB feeds into
Plate IV — Thesis Breakers
What would invalidate this.
- Risk 01PCIe 7 standardization stalls
- Risk 02CXL demand disappoints
Plate V — Also on the Silicon plate
Siblings by pillar.
- NVDAScore 10The king: GPUs, the CUDA moat, Mellanox networking, and the expanding software stack.
- TSMScore 10Fabs every leading-edge AI chip on earth — the real bottleneck of the entire stack.
- ASMLScore 10EUV lithography monopoly; no EUV means no sub-5nm chips.
- CRDOScore 10Active electrical cables and SerDes for AI-rack interconnect; pure-play AI networking IC.
- AVGOScore 9Custom silicon partner to Google (TPU) and Meta (MTIA); dominant AI networking ASICs.
