You can look up the asic family from the marketing name here:
http://en.wikipedia.org/wiki/Ati_gpu
R7 250 is Oland based.

And these pages have some details of the hardware features on the asics:
http://www.x.org/wiki/RadeonFeature/
http://www.amd.com/en-us/products/graphics/desktop/r7#
http://www.amd.com/en-us/products/graphics/desktop/oem/r7#

Dual-link DVI monitors require 2 links per monitor.  Oland chips only support 2
digital links.  Most other chips support 6.
