Technology
- Main article: Broadwell § Technology
Goldmont-based chips are manufactured on Intel's 14 nm process.
Architecture
Airmont is for the most part identical to Silvermont with some higher number of execution units to the GPU in some of the higher-end models.
Key changes from Silvermont
- DTLB table size doubled (128 entries -> 256 entries)
- L2 latency increased
- Reorder Buffer was increased (from 32 entries to 48)
- Gen 8 GPUs
