Differences

Reasons to consider the AMD FX-8350

  • CPU is newer: launch date 7 year(s) 4 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 50% higher clock speed: 4.2 GHz vs 2.8 GHz
  • A newer manufacturing process allows for a more powerful, yet cooler running processor: 32 nm SOI vs 90 nm
  • 24x 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
  • 3x better performance in Geekbench 4 - Multi-Core: 2751 vs 906
