Gracemont is a microarchitecture for low-power processors used in systems on a chip (SoCs) made by Intel, and is the successor to Tremont. Like its predecessor, it is also implemented as low-power cores in a hybrid design of the Alder Lake and Raptor Lake processors.[2]

Design

Gracemont is the 4th generation out-of-order low-power Atom microarchitecture, built on the Intel 7 manufacturing process.

The Gracemont microarchitecture has the following enhancements over Tremont:[3][4]

Level 1 cache per core:
- 8-way-associative 64 KB instruction cache
- 8-way-associative 32 KB data cache
DDR5 memory
PCI Express 5.0 support
Support for AVX, AVX2, FMA3 and AVX-VNNI instructions[5]
