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, Raptor Lake and Raptor Lake Refresh processors.

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

The Gracemont microarchitecture has the following enhancements over Tremont:

Level 1 cache per core: Eight-way-associative 64KB instruction cache Eight-way-associative 32KB data cache New on-demand instruction-length decoder Instruction issue increased to five per clock (from four) Instruction retire increased to eight per clock (from seven) Execution ports (functional units) there are now 17 (from ten) Reorder buffer increased to 256 entries (from 208) Improved branch prediction Support for AVX, AVX2, FMA3 and AVX-VNNI instructions 2 or 4MB shared L2 cache per 4-core cluster. Alder Lake family has 2MB. Higher-end Raptor Lake family with Raptor Cove has 4MB, while Lower-end Raptor Lake family with Golden Cove has 2MB.

List of Gracemont processors

The microarchitecture is used as the efficient cores of the 12th generation of Intel Core hybrid processors (codenamed "Alder Lake"), the 13th generation of Intel Core hybrid processors (codenamed "Raptor Lake") and the 14th generation of Intel Core hybrid processors (codenamed "Raptor Lake Refresh"). It's also used in the Alder Lake-N line-up as the only core cluster, intended for low-power applications.
