Gracemont is amicroarchitecture for low-power processors used insystems on a chip (SoCs) made byIntel, and is the successor toTremont. Like its predecessor, it is also implemented as low-power cores in a hybrid design of theAlder Lake,Raptor Lake and Raptor Lake Refresh processors.^[2]

Gracemont is the fourth generationout-of-order low-powerAtom microarchitecture, built on theIntel 7 manufacturing process.^[3]

The Gracemont microarchitecture has the following enhancements overTremont:^[4][3]

• Level 1 cache per core:
  • eight-way-associative 64 KB instruction cache
  • eight-way-associative 32 KB 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 forAVX,AVX2,FMA3 andAVX-VNNI instructions^[5]
• 2 or 4 MB sharedL2 cache per 4-core cluster^[3] Alder Lake-S/H/P/U family has 2 MB. Raptor Lake-S/H/P/U family has 4 MB.

• System on a chip (SoC) architecture
• 3Dtri-gate transistors
• Thermal design power (TDP)
  • 10 W desktop processors
  • 6 W mobile 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 theAlder Lake-N line-up as the only core cluster, intended for low-power applications.
