Custom AI Silicon

Workload-specific chips and the designers that bring them to production

Heat (est.) Spend (est.)

Every large buyer is moving volume in-house, which is the biggest share shift in compute and the main threat to merchant accelerators.

Custom AI silicon matches hardware to a particular model, cloud fleet or autonomy stack. Hyperscalers and labs own the requirements, while specialist partners provide implementation and reusable IP. The map separates chip programs from foundry capacity and system assembly.

Why now

OpenAI has disclosed Jalapeno, Google has split its next TPU generation into training and inference variants, and Marvell has added a Google custom-silicon agreement. Chiplets broaden design options while Korean and Taiwanese partners win more advanced-node work.

Custom Compute Partners

Merchant designers translate hyperscaler or model-specific requirements into production compute silicon. They supply architecture, physical implementation and integration rather than simply selling standard GPUs.

Glossary

ASIC
An application-specific integrated circuit designed for a defined workload rather than general-purpose use.
RTL
Register-transfer-level code describes a digital circuit before its logic is mapped into physical silicon.
Turnkey
A design engagement that can cover implementation, tapeout and delivery of finished chips to the customer.
Chiplet
A separately designed silicon die combined with other dies to create a larger processor or system chip.
Tapeout
The release of final chip design data for manufacturing; it does not by itself mean volume production.
