Differences

Reasons to consider the Intel Core i7-8700K

  • CPU is newer: launch date 9 year(s) 6 month(s) later
  • Processor is unlocked, an unlocked multiplier allows for easier overclocking
  • 4 more cores, run more applications at once: 6 vs 2
  • Around 135% higher clock speed: 4.70 GHz vs 2 GHz
  • A newer manufacturing process allows for a more powerful, yet cooler running processor: 14 nm vs 65 nm
  • 4x more L1 cache, more data can be stored in the L1 cache for quick access later
  • 3.5x better performance in PassMark - Single thread mark: 2721 vs 788
  • 18.4x better performance in PassMark - CPU mark: 13585 vs 737
  • 5x better performance in Geekbench 4 - Single Core: 1276 vs 255
  • 15.2x better performance in Geekbench 4 - Multi-Core: 6678 vs 440
