Tremont (microarchitecture)

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

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[lower-alpha 1] 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.
