P4 's real performance is limited by its "长流水线".
P4 has same or a little higher peak performance then k7/k8,
for some certain applications which can drive P4 to its peak performance, they run a little better then k7 and k8.

4v~W3Md^;y"uP4的效率低的主要原因,不是什么L2不足,也不是什么超长流水线,P4从理论上就不是一个高效的处理器,无论是解码器还是整数、浮点执行单元都比K7/K8少得多。 |
