Differences
Reasons to consider the AMD EPYC 7451
- CPU is newer: launch date 3 year(s) 9 month(s) later
- Processor is unlocked, an unlocked multiplier allows for easier overclocking
- 16 more cores, run more applications at once: 24 vs 8
- 32 more threads: 48 vs 16
- A newer manufacturing process allows for a more powerful, yet cooler running processor: 14 nm vs 22 nm
- 4.5x more L1 cache, more data can be stored in the L1 cache for quick access later
- 6x more L2 cache, more data can be stored in the L2 cache for quick access later
- 3.2x more L3 cache, more data can be stored in the L3 cache for quick access later
- Around 17% better performance in PassMark - Single thread mark: 1931 vs 1655
- 3.1x better performance in PassMark - CPU mark: 52322 vs 17033
