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: 1332 vs 435
- 11.8x better performance in PassMark - CPU mark: 4636 vs 394
- 2.1x better performance in Geekbench 4 - Multi-Core: 2092 vs 979
