Basically, in order with a clear potential for improvement

The Hautptvorteil the map is an existing DisplayPort 1.2, which allows you to send UHD signals with 60 Hz to a monitor.
This can my knowledge no other passive Map this performance class (the Radeon 7750 or R7 250 is much weaker).
The performance of the card corresponding to an actively cooled card the GTX 750 series. Who buys them knows what performance to expect. In passive cooling concept is in my opinion potential for improvement. Thus a heat pipe was compared to its predecessor, saving and the size of the passive heatsink unnecessarily reduced - and was already not the greatest. The result is that for safe cooling a stronger case ventilation is necessary - because of a few cents saved on heatsink fins ... the target group is yes but really Silent-PC owners - and who want as little as possible and slow fan.
Another comparison: Previously I had a Sapphire Radeon 7750 Ultimate, whose temperature was in my fully insulated housing with a slowly rotating 12cm case fan under load to a maximum of 70 ° C.
The Zotac Zone achieved in this case just under 80 ° C - which is the range of ballast temperature. Comes as no surprise, since the heat sink of the Ultimate despite lower waste heat from the ATI chip has a much larger surface.
Since the card after registration at Zotac has 5 year warranty, the matter can see you really left. Really happy but I'm not using this solution - which would easily much better ....
Unfortunately, there are few other models whose cooling fins are arranged along the card ... the card from Palit z. B. It also has cross ... but since the cooler is at least considerably larger.
I'm going to probably make it a very low-speed fan.
