Differences

Reasons to consider the AMD EPYC 7551

  • CPU is newer: launch date 3 year(s) 9 month(s) later
  • Processor is unlocked, an unlocked multiplier allows for easier overclocking
  • 26 more cores, run more applications at once: 32 vs 6
  • 52 more threads: 64 vs 12
  • A newer manufacturing process allows for a more powerful, yet cooler running processor: 14 nm vs 22 nm
  • 8x more L1 cache, more data can be stored in the L1 cache for quick access later
  • 10.7x more L2 cache, more data can be stored in the L2 cache for quick access later
  • 4.3x more L3 cache, more data can be stored in the L3 cache for quick access later
  • 5.4x better performance in PassMark - CPU mark: 55754 vs 10278
  • 3.6x better performance in Geekbench 4 - Single Core: 2956 vs 816
  • 4.1x better performance in Geekbench 4 - Multi-Core: 20125 vs 4969
