Alder Lake (microprocessor)

Alder Lake is Intel's codename for the 12th and upcoming generation of Intel Core processors based on a hybrid architecture utilizing Golden Cove high-performance cores and Gracemont power-saving cores.[1] Intel expects to launch Alder Lake in the second half of 2021. It is expected to use the 10 nm Enhanced SuperFin (ESF) process[2] and a new LGA 1700 socket[3] with DDR5 support.

Architecture changes in comparison with Tiger Lake

CPU
  • Intel Golden Cove big CPU cores & Gracemont small CPU cores
    • New instruction set extensions:[4]
      • CLDEMOTE
      • PTWRITE
      • User Wait: TPAUSE, UMONITOR, UMWAIT
      • Architectural LBRs
      • HLAT
      • SERIALIZE
      • AVX-VNNI
      • Enhanced Hardware Feedback Interface (EHFI) and HRESET
  • Next generation hardware scheduler, which will be able to leverage all cores for performance and make it seamless to any software package.[5] Adding support for these advanced scheduling capabilities will require Microsoft to add support for them to x86-64 Windows.[6]
