Serenity Stock Themes
Serenity's bottleneck theory groups AI hardware stocks by the physical constraint they address. Browse the tracked mentions by theme.
Themes
- Co-Packaged Optics (CPO) & Silicon Photonics – Co-packaged optics (CPO) moves optical engines next to the switch or accelerator chip, so AI clusters can move more data with less power.
- Glass Substrates for AI Packaging – Glass core substrates are being developed to replace organic substrates in large AI accelerator packages, offering flatter surfaces and finer wiring.
- HBM, Memory & Storage – High-bandwidth memory (HBM) is stacked DRAM placed beside AI GPUs, and it is one of the tightest supply constraints in AI hardware.
- Advanced Packaging & Foundries – Advanced packaging (CoWoS, chiplets, system-in-package) and specialty foundries determine how many AI accelerators can actually be shipped.
