STM32H7R3I8K6 vs STM32H750IBK6 current draw?

I'm trying to get a ballpark estimate of what sort of current draw consumption I can expect if we migrate to the H7R3, which uses a SMPS for the core, as opposed to the built-in LDO for the core on the H750.

Is there a place I can compare the current draw of these two devices?

Also, is there a hardware design guide for the H7R3? Seems there are pretty significant hardware changes required to migrate from H750 to H7R3 and it isn't drop-in compatible.

Dear @jaakjensen ,

You can refer this application Note for migration from H750 to H7RS  : Migrating from STM32H730 and STM32H750 to STM32H7Rx/7Sx MCUs - Application note  and check hardware points in section 4.  

Hope it helps you.
