Differences

Reasons to consider the AMD EPYC 7351P

  • CPU is newer: launch date 4 year(s) 7 month(s) later
  • Processor is unlocked, an unlocked multiplier allows for easier overclocking
  • 16 more threads: 32 vs 16
  • A newer manufacturing process allows for a more powerful, yet cooler running processor: 14 nm vs 32 nm
  • 2x more L1 cache, more data can be stored in the L1 cache for quick access later
  • 4x more L3 cache, more data can be stored in the L3 cache for quick access later
  • Around 76% better performance in PassMark - Single thread mark: 1788 vs 1018
  • 2.1x better performance in PassMark - CPU mark: 25657 vs 12352
