🟠It "democratizes" HBM.

SemiAnalysis argues that SPHBM4 will break HBM out of its advanced-packaging bottleneck, enabling standard packaging houses to adopt it and expanding HBM demand into mid-tier AI chips, networking silicon, and consumer gaming GPUs.

Claims
- HBM is currently restricted to ultra-premium AI accelerators because only a few specialized foundries with advanced packaging technology such as TSMC CoWoS can build it.
- SPHBM4 allows standard packaging houses to wire HBM, removing the current supply bottleneck.
- Mid-tier AI chips, networking silicon, and consumer gaming GPUs become viable HBM candidates once SPHBM4 is available.
- HBM demand will grow faster than suppliers can increase capacity even as SPHBM4 broadens the supply base.
Key quotes
Right now, HBM is locked behind a massive bottleneck: only a few specialized foundries have the advanced packaging tech (like TSMC CoWoS) to build them. This keeps HBM restricted to ultra-premium AI accelerators.
SPHBM4 changes the game. By allowing standard packaging houses to wire HBM, mid-tier AI chips, networking silicon, and even consumer gaming GPUs can adopt it.
HBM demand will continue to grow faster than suppliers can even increase capacity.
