Differences

Reasons to consider the AMD EPYC 7351

  • CPU is newer: launch date 3 year(s) 7 month(s) later
  • Processor is unlocked, an unlocked multiplier allows for easier overclocking
  • 4 more cores, run more applications at once: 16 vs 12
  • 8 more threads: 32 vs 24
  • A newer manufacturing process allows for a more powerful, yet cooler running processor: 14 nm vs 22 nm
  • 2x more L1 cache, more data can be stored in the L1 cache for quick access later
  • 2.7x more L2 cache, more data can be stored in the L2 cache for quick access later
  • 2.1x more L3 cache, more data can be stored in the L3 cache for quick access later
  • Around 75% better performance in Geekbench 4 - Single Core: 3547 vs 2030
  • Around 31% better performance in Geekbench 4 - Multi-Core: 23587 vs 18071
