Intel Xeon E5-2651 v2

AMD EPYC 7351

Differences

Reasons to consider the AMD EPYC 7351

CPU is newer: launch date 3 year(s) 7 month(s) later
Processor is unlocked, an unlocked multiplier allows for easier overclocking
4 more cores, run more applications at once: 16 vs 12
8 more threads: 32 vs 24
A newer manufacturing process allows for a more powerful, yet cooler running processor: 14 nm vs 22 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 75% better performance in Geekbench 4 - Single Core: 3547 vs 2030
Around 31% better performance in Geekbench 4 - Multi-Core: 23587 vs 18071
