Architecture[edit]

Tremont is designed with significant single-thread performance in mind while focusing on low-power small silicon area cores.

Key changes from Goldmont Plus[edit]

  • Significant IPC uplift (Intel self-reported average 32% IPC across proxy benchmarks such as SPEC CPU2006/SPEC CPU2017)
  • Front-end
    • Redesigned front-end
      • New dual symmetric decode cluster
        • Out-of-order decode
        • 6-wide decode
          • 3-way decode per cluster
    • Smarter prefetchers
    • Improved branch predictor
      • Big-core level of performance
  • Back-end
    • larger ROB
    • wide issue (10-wide)
  • Execution Engine
    • 2x store data ports (up from 1)


New instructions[edit]

Tremont introduced a number of new instructions:

  • CLWB - Force cache line write-back without flush
  • ENCLV - SGX oversubscription instructions
  • CLDEMOTE - Cache line demote instruction
  • SSE_GFNI - SSE-based Galois Field New Instructions
  • Direct store instructions: MOVDIRI, MOVDIR64B
  • User wait instructions: TPAUSE, UMONITOR, UMWAIT
  • Split Lock Detection - detection and cause an exception for split locks
