What the shared parts are
- Hyperscaler custom ASICs — AI accelerator chips (often called XPUs) designed in-house by a hyperscaler for its own fleet, typically co-developed with an outside ASIC design partner and fabbed by a merchant foundry.
- Hyperscaler Arm CPUs — Arm-based server CPUs designed in-house by a hyperscaler for its own fleet, such as AWS Graviton, Google Axion, and Microsoft Cobalt.
- Hyperscalers, neoclouds & model labs — The hyperscalers, neoclouds, and AI labs that occupy data center capacity as tenants or owner-operators, and whose capital spending ultimately drives demand for every layer below this one.

Questions
- Do Amazon and Microsoft compete?
- In this catalog they are both placed on 3 of the same parts, across 2 layers: Hyperscaler custom ASICs, Hyperscaler Arm CPUs, Hyperscalers, neoclouds & model labs. Sharing a part does not mean selling the same product to the same buyer, so read each row's product note.
- Which has more placements, Amazon or Microsoft?
- Amazon has 3 placements and Microsoft has 4. Placement counts reflect how thoroughly each company has been catalogued as well as its real breadth, so they are not a ranking.
