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
- 6 more cores, run more applications at once: 8 vs 2
- 12 more threads: 16 vs 4
- A newer manufacturing process allows for a more powerful, yet cooler running processor: 14 nm vs 22 nm
- 6x 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
- 4x more L3 cache, more data can be stored in the L3 cache for quick access later
- Around 11% better performance in PassMark - Single thread mark: 1671 vs 1505
- 6.6x better performance in PassMark - CPU mark: 14935 vs 2248
