Contents
Process Technology
Lake Crest is fabricated on TSMC's 28 nm process.
Architecture
Lake Crest was designed from the ground up for deep learning. The architecture itself is a tensor-based architecture, meaning it's optimized for blocks of compute instead of operating on scalars (as would a traditional Intel CPU would).
- Tensor-based architecture
- Nervana Engine
- Flexpoint number format
- No caches
- Software explicitly manages all on-chip memory
- HBM2 memory
- 32 GiB of in-package memory
- 8 Tbit/s bandwidth
- 12 bi-directional high-bandwidth direct chip-to-chip interconnect
