Differences

Reasons to consider the AMD A8-6600K

  • CPU is newer: launch date 4 year(s) 10 month(s) later
  • Processor is unlocked, an unlocked multiplier allows for easier overclocking
  • Around 68% higher clock speed: 4.2 GHz vs 2.5 GHz
  • A newer manufacturing process allows for a more powerful, yet cooler running processor: 32 nm SOI vs 65 nm
  • 2x more L2 cache, more data can be stored in the L2 cache for quick access later
  • Around 46% lower typical power consumption: 65 Watt vs 95 Watt
  • Around 55% better performance in PassMark - Single thread mark: 1537 vs 992
  • Around 55% better performance in PassMark - CPU mark: 3007 vs 1946
