The are Cape Verde based asics (Southern Islands family).  They are
supported by the radeon kernel module and they use the radeonsi mesa
driver for 3D, etc.  amdgpu is a kernel driver for VI (Volcanic
Islands) and newer parts.  The radeonsi mesa driver supports SI and CI
parts supported by the radeon kernel driver and VI parts supported by
the amdgpu kernel driver.
