Differences

Reasons to consider the AMD FX-8120

  • CPU is newer: launch date 7 year(s) 5 month(s) later
  • Processor is unlocked, an unlocked multiplier allows for easier overclocking
  • 7 more cores, run more applications at once: 8 vs 1
  • Around 82% higher clock speed: 4 GHz vs 2.2 GHz
  • A newer manufacturing process allows for a more powerful, yet cooler running processor: 32 nm vs 90 nm
  • 3x more L1 cache, more data can be stored in the L1 cache for quick access later
  • 8x more L2 cache, more data can be stored in the L2 cache for quick access later
  • 3.1x better performance in PassMark - Single thread mark: 1335 vs 435
  • 11.8x better performance in PassMark - CPU mark: 4641 vs 394
  • 2.1x better performance in Geekbench 4 - Multi-Core: 2092 vs 979
