Шаблон:Short description Шаблон:Use mdy dates Шаблон:Infobox CPU
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.[1]
Design
Gracemont is the fourth generation out-of-order low-power Atom microarchitecture, built on the Intel 7 manufacturing process.[2]
The Gracemont microarchitecture has the following enhancements over Tremont:[3][2]
- Level 1 cache per core:
- eight-way-associative 64Шаблон:NbspKB instruction cache
- eight-way-associative 32Шаблон:NbspKB 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)
- Improved branch prediction
- Support for AVX, AVX2, FMA3 and AVX-VNNI instructions[4]
- 2 or 4Шаблон:NbspMB shared L2 cache per 4-core cluster[2] Alder Lake-S/H/P/U family has 2Шаблон:NbspMB. Raptor Lake-S/H/P/U family has 4Шаблон:NbspMB.
Technology
- System on a chip (SoC) architecture
- 3D tri-gate transistors
- Thermal design power (TDP)
- 10Шаблон:NbspW desktop processors
- 6Шаблон:NbspW mobile processors
List of Gracemont processors
Шаблон:Main 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 used exclusively in the Alder Lake-N line-up.
