The configuration of the two computers is very different. Why is the score so different?

I just want to tell you that Master Lu is for show, and profiteers like to use Master Lu to fool people who don't understand hardware. The rating is completely unreliable, and GT530 and 6850 are not in the same grade. If you want to run the spectrum, please use 3DMARK and AIDA64. By the way, I really can't understand the topic of LZ. The configurations of these two computers are quite different. "Why is the score gap so big? Since you all know that there is a big difference in configuration, it is normal to have a big difference in scores. "
