Intel Xeon E5-2678 v3

AMD EPYC 7501

Differences

Reasons to consider the Intel Xeon E5-2678 v3

Around 42% lower typical power consumption: 120 Watt vs 155/170 Watt

Thermal Design Power (TDP)	120 Watt vs 155/170 Watt

Reasons to consider the AMD EPYC 7501

Processor is unlocked, an unlocked multiplier allows for easier overclocking
20 more cores, run more applications at once: 32 vs 12
40 more threads: 64 vs 24
A newer manufacturing process allows for a more powerful, yet cooler running processor: 14 nm vs 22 nm
4x more L1 cache, more data can be stored in the L1 cache for quick access later
5.3x 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
