农企不止硬件有黑科技，软件黑科技也要来了，PBO2即将更新，自动挡单核提升2%多核提升10%且电压更低

简单总结下PBO2(Precision Boost Overdrive 2)特性：
1：农企明年会更新支持PBO2的新版本AMD Ryzen Master，但现在已经有不少主板厂商已经放出支持PBO2 AGESA V2 1.1.8.0的测试BIOS(比如ASUS C7H)。
2：想要使用PBO2你需要满足三点：Zen3处理器、400或500系主板、AGESA V2 1.1.8.0 BIOS。
3：PBO2在超频中加入了自适应降压技术(adaptive undervolting)，在高低负载下尽可能降低电压，而不是单纯地全程固定降低电压，而且电压阶级单位高达30级，每级对应3-5mV电压。
4：自适应降压技术在CCD越多且CCD内核心数越少的情况下，提升更明显，比如可以使5900X单核性能提升2%，多核性能提升10%。
5：PBO2只支持Zen3处理器。
