"As with much of the new Radeon R9 and R7 range with the R7 250 HIS And AMD are re-using an existing GPU, in this case Oland which is the same base for the likes of AMDs 8500 and 8700 mobile GPUs.
The HIS version of the card sticks with what is important, keeping the small PCB and attaching a quiet cooler to it. Performance is also good, in fact surprisingly so. When we began testing the R7 250 iCooler it seemed like 1920x1080 with any sort of detail would be a stretch but as we went on it was clear that this little card was a very capable gamer. Not only did we get to game on medium/high detail a lot there was also a noticeable increase in performance over the similarly priced GT 640.
Also worthy of note is that R7 250 supports AMD Mantle..."
