The closest standalone sensor you could compare the BNO055 to would be the BMA280, BMG160 and BMM150. The performance values will differ, but you may refer to their respective datasheet for an overview of their functional description.
In particuar, you will find in BMA280's datasheet that the sampling rate of filtered acceleration data is always twice the selected bandwidth (i.e. BW = ODR/2), and in BMG160's datasheet you will find a table with the ODR corresponding to each available filter bandwidth.
Available configurations of raw sensor modes of the BNO055 are listed in chapter 3.5 of its datasheet.
