针对前几天的推土机假图，发一个PI预测：同频K10.5慢50%略少

AMD共享浮点战术&Core Boost和Intel的HTT & Turbo Boost一个道理，一是在一定成本下维持单核心性能，二是在任务管理器里面给你更多的框

和HTT不同，HTT是强于原生四核弱于原生八核；推土机是整数等于原生八核，浮点等于原生四核；但是相同的，都给你8个框

"There are four integer execution units per core. Twounits which handle all arithmetic, logical and shift operations (EX). And two whichhandle address generation and simple ALU operations (AGLU)."

bulldozer 2ALU+2AGU 对
k101.5 ALU and 1.5 AGU

整数单线程性能明显是加强了
