About intel i7 cpu predict 320*320 very slowly problem?

[l35633]

I trained model using NVIDIA Tesla P100, My cpu is intel i7 1.8G, Why infer 320*320 needing about 30ms, where is wrong?
Kirin 990 CPU’s time only is 6.74ms!! where is wrong?
Thank you very much!

我用NVIDIA Tesla P100训练的模型，在intel i7 1.8G cpu上预测320*320的时间是30ms左右，但是根据官网，Kirin 990 CPU预测同样大小是6.74ms。
这个差距太大了，是哪里出了问题？非常感谢！
