LT8364 vs LT3471 in terms of noise

Hi,

 

Recently I use a LT8364 in a boost converter circuit with switching frequency of 1.2MHz, and found that it's noise is quite higher than a LT3471 boost converter circuit I've previously used. Is the LT8364 a higher noise part than the LT3471?

 

Attached is the noise spectrum I've measured between the 2, the circuits are pretty much taken from the datasheet.

 

Thanks and regards.
