ThunderX3

ThunderX3 looks like quite a leap over TX2. It's a 96-core DCM or 60-core SCM. Some of the highlights:


  • 30% iso-clock ST int gain

  • 2-3x throughput for single die relative to TX2

  • L1I increased to 64K, L2 to 512K

  • 4-way SMT costs ~5% area over no SMT, which sounds like a no-brainer to me; they claim +28% gain from SMT for "High IPC" streams (with x264 as a proxy), +73% for "Medium IPC" (Leela), and +121% for "Low IPC" (MySQL.)



This thing looks positively scary.
