You can't simply use a "number greater than N" comparison, due to what 
we call "Rebrandeon" :D
i.e. models identical to an older generation getting new numbers, for 
the low-end models.

You have to look at Wikipedia:

https://en.wikipedia.org/wiki/List_of_AMD_graphics_processing_units#Radeon_HD_7000_series

and check the Architecture column.

Yep, HD7730 is Cape Verde, all good.
(While HD8350-8490 and R5 220-235X are TeraScale rebrands.)
