i.MX6Q - is there a CPU performance hit with LPDDR2 vs. DDR3?

Hello:

 

Presently we are using DDR3 memory on our i.MX6 design.  We are using the iMX6Q running at 528MHz, The memory interface is 64 bits wide.

 

If we were to change this to LPDDR2 (at the same clock speed), are there any drawbacks on processor bandwidth, performance, etc.?

 

The LPDDR2 operates at 1.2V instead of 1.5V so it would be a substantial power savings for our application which can be portable or battery powered temporarily.

 

Any feedback or input is welcomed and appreciated!

 

Thanks!

Paul
