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.[2]
Design
Gracemont is the fourth generation out-of-order low-power Atom microarchitecture, built on the Intel 7 manufacturing process.[3]
The Gracemont microarchitecture has the following enhancements over Tremont:[4][3]
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 eight)
Reorder buffer increased to 256 entries (from 208)
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.
^Price is Recommended Customer Price (RCP) at launch. RCP is the trade price that processors are sold by Intel to retailers and OEMs. Actual MSRP for consumers is higher
