Architecture
Tremont is designed with significant single-thread performance in mind while focusing on low-power small silicon area cores.
Key changes from Goldmont Plus
- Significant IPC uplift (Intel self-reported average 32% IPC accross 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
- New dual symmetric decode cluster
- Smarter prefetchers
- Improved branch predictor
- Big-core level of performance
- Redesigned front-end
- Back-end
- larger ROB
- wide issue (10-wide)
- Execution Engine
- 2x store data ports (up from 1)
New instructions
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
