Tremont is a microarchitecture for low-power Atom, Celeron and Pentium Silver branded processors used in systems on a chip (SoCs) made by Intel. It is the successor to Goldmont Plus.[2] Intel officially launched Elkhart Lake platform with 10 nm Tremont core on September 23, 2020.[3] Intel officially launched Jasper Lake platform with 10 nm Tremont core on January 11, 2021.[4]
Design[edit]
Tremont is the third generation out-of-order low-power Atom microarchitecture designed for the entry level desktop and notebook computers. Tremont is built on the 10 nm manufacturing process and supports up to 24 cores.[5] It includes the Intel Gen11 graphics architecture from Ice Lake.
Tremont microarchitecture provides the following enhancements over Goldmont Plus:
- Enhanced branch-prediction unit.
- Increased capacity with improved path-based conditional and indirect prediction.
- New committed return stack buffer.
- Novel clustered 6-wide out-of-order front-end fetch and decode pipeline.
- Banked ICache with dual 16B reads.
- Two 3-wide decode clusters enabling up to 6 instructions per cycle.
- Deeper back-end out-of-order windows.
- 32 KB[a] data cache.
- Larger load and store buffers.
- Dual generic load and store execution pipes capable of 2 loads, 2 stores, or 1 load and 1 store per cycle.
- Dedicated integer and vector integer/floating point store data ports.
- New and improved cryptography.
- New Galois-field instructions (GFNI).
- Dual AES units.
- Enhanced SHA-NI implementation.
- Faster PCLMULQDQ.
- Support for user level low-power and low-latency spin-loop instructions UMWAIT/UMONITOR and TPAUSE.
Technology[edit]
- 10 nm manufacturing process
