Differences

Reasons to consider the AMD EPYC 7501

  • CPU is newer: launch date 7 year(s) 3 month(s) later
  • Processor is unlocked, an unlocked multiplier allows for easier overclocking
  • 28 more cores, run more applications at once: 32 vs 4
  • 56 more threads: 64 vs 8
  • A newer manufacturing process allows for a more powerful, yet cooler running processor: 14 nm vs 32 nm
  • 12x more L1 cache, more data can be stored in the L1 cache for quick access later
  • 16x more L2 cache, more data can be stored in the L2 cache for quick access later
  • 5.3x more L3 cache, more data can be stored in the L3 cache for quick access later
  • Around 33% better performance in PassMark - Single thread mark: 1925 vs 1445
  • 2.9x better performance in PassMark - CPU mark: 24925 vs 8462
