测试使用Tyan B8026T70AE24HR系统

单路EPYC 7601，32C/64T， 180W TDP，单核Boost 3.2GHz，全核Boost 2.7GHz

内存为8x16GB DDR4 2666 RDIMM（八通道）

对比系统为Tyan GT24E-B7106

双路Xeon Gold 6138，40C/80T，2x 125W TDP，单核Boost 3.7GHz，全核Boost 2.7GHz

内存为12x8GB DDR4 2666 RDIMM（2x 六通道）

EPYC 7601为双路处理器，售价大概4200刀；而两颗Xeon Gold 6138需要大概5200刀

更重要的是单路旗舰EPYC 7551P实际上只需要2100刀，为7601的一半。

Xeon Gold 6138核心数量比EPYC 7601多出20%，单核频率更高，全核频率相同，但由于是双路所以更容易维持高频率。
