Differences

Reasons to consider the AMD A8-3870K

  • CPU is newer: launch date 1 year(s) 10 month(s) later
  • Processor is unlocked, an unlocked multiplier allows for easier overclocking
  • 2 more cores, run more applications at once: 4 vs 2
  • A newer manufacturing process allows for a more powerful, yet cooler running processor: 32 nm vs 45 nm
  • 2x more L1 cache, more data can be stored in the L1 cache for quick access later
  • 2x more L2 cache, more data can be stored in the L2 cache for quick access later
  • Around 98% better performance in PassMark - CPU mark: 2328 vs 1175
  • Around 6% better performance in Geekbench 4 - Single Core: 373 vs 353
  • Around 78% better performance in Geekbench 4 - Multi-Core: 1172 vs 660
