History
Predecessor	Goldmont Plus
Successor	Gracemont[1]

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 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.
