Hi Jian

for performance data one can look on

White Paper: Memory Expansion with Adesto EcoXIP and i.MX RT
p.9 sect."UNDERSTANDING XIP PERFORMANCE" 
https://www.nxp.com/docs/en/white-paper/NXPADESTOWP.pdf

https://mcu-things.com/blog/imxrt-how-to-coremark-implementation/ 

With cache enabled, the memories perform very closely to one another.
