The mesa drivers are named for the *first* chip they support (since we don't know what the last chip will be when creating a new driver), so...

r300 mesa driver supports r3xx, 4xx, 5xx
r600 mesa driver supports r6xx, 7xx, Evergreen, Northern Islands
radeonsi mesa driver supports SI, CI, VI and beyond
----
radeon kernel driver supports everything from r100 through CI
amdgpu kernel driver supports SI, CI, VI and beyond, however SI support is recent and we are still adding chip support, SI and CI upstream default is still radeon.
It's probably easiest to think about amdgpu initially supporting VI and up, then being extended *back* to include SI so that the amdgpu-pro stack can fully replace the previous fglrx/Catalyst Linux stack..
