Differences
Reasons to consider the AMD EPYC 7251
- CPU is newer: launch date 5 year(s) 1 month(s) later
- Processor is unlocked, an unlocked multiplier allows for easier overclocking
- 2 more cores, run more applications at once: 8 vs 6
- 4 more threads: 16 vs 12
- A newer manufacturing process allows for a more powerful, yet cooler running processor: 14 nm vs 32 nm
- 2x more L1 cache, more data can be stored in the L1 cache for quick access later
- 2.7x more L2 cache, more data can be stored in the L2 cache for quick access later
- 2.1x more L3 cache, more data can be stored in the L3 cache for quick access later
- Around 48% better performance in PassMark - Single thread mark: 1671 vs 1132
- Around 40% better performance in PassMark - CPU mark: 14935 vs 10663
