Differences

Reasons to consider the AMD EPYC 7351

Processor is unlocked, an unlocked multiplier allows for easier overclocking
8 more cores, run more applications at once: 16 vs 8
24 more threads: 32 vs 8
A newer manufacturing process allows for a more powerful, yet cooler running processor: 14 nm vs 32 nm
4x more L1 cache, more data can be stored in the L1 cache for quick access later
8x more L3 cache, more data can be stored in the L3 cache for quick access later
Around 66% better performance in PassMark - Single thread mark: 1747 vs 1054
4x better performance in PassMark - CPU mark: 25431 vs 6384
