Differences

Reasons to consider the AMD EPYC 7501

CPU is newer: launch date 7 year(s) 3 month(s) later
Processor is unlocked, an unlocked multiplier allows for easier overclocking
28 more cores, run more applications at once: 32 vs 4
56 more threads: 64 vs 8
A newer manufacturing process allows for a more powerful, yet cooler running processor: 14 nm vs 32 nm
12x more L1 cache, more data can be stored in the L1 cache for quick access later
16x more L2 cache, more data can be stored in the L2 cache for quick access later
5.3x more L3 cache, more data can be stored in the L3 cache for quick access later
Around 33% better performance in PassMark - Single thread mark: 1925 vs 1445
2.9x better performance in PassMark - CPU mark: 24925 vs 8462
