Differences

Reasons to consider the AMD FX-4100

  • CPU is newer: launch date 4 year(s) 5 month(s) later
  • Processor is unlocked, an unlocked multiplier allows for easier overclocking
  • 2 more cores, run more applications at once: 4 vs 2
  • Around 78% higher clock speed: 3.8 GHz vs 2.13 GHz
  • Around 17% higher maximum core temperature: 70.50°C vs 60.1°C
  • A newer manufacturing process allows for a more powerful, yet cooler running processor: 32 nm SOI vs 65 nm
  • 3x more L1 cache, more data can be stored in the L1 cache for quick access later
  • Around 64% better performance in PassMark - Single thread mark: 1288 vs 785
  • 3.4x better performance in PassMark - CPU mark: 2617 vs 760
  • Around 56% better performance in Geekbench 4 - Single Core: 463 vs 296
  • 2.4x better performance in Geekbench 4 - Multi-Core: 1286 vs 541
