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]

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.

• 10 nm manufacturing process
• SoC (System on a chip) architecture
• 3D tri-gate transistor
• 32 KB^[a] L1 data cache, up from 24 KB in Goldmont Plus
• 1.5–4.5 MB shared L2 cache per 4-core cluster, up from 4 MB in Goldmont Plus
• 4 MB shared L3 cache
• Gen 11 GPU^{[6] [7]} with DirectX 12, OpenGL 4.6, Vulkan 1.3, OpenGL ES 3.2 and OpenCL 3.0 support.
• 10 W thermal design power (TDP) desktop processors
•  6 W TDP mobile processors

List of mobile processors as follows:^[8]

Pentacore Lakefield CPU consists of 1 "big" Sunny Cove core and 4 "little" Tremont cores. AVX support on Sunny Cove (still physically present) is disabled to match Tremont core.

These processors are exclusively produced for cell phone radio manufacturers.^[9]
