Sapphire HD7730 2GB GDDR3 and 1GB GDDR5 Review

The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 24c – a comfortable environment for the majority of people reading this. Idle temperatures were measured after sitting at the desktop for 30 minutes.Load measurements were acquired by playing Crysis Warhead for 30 minutes and measuring the peak temperature.

We also have included Furmark results, recording maximum temperatures throughout a 30 minute stress test. All fan settings were left on automatic.



The Sapphire HD7730 2GB GDDR3 version runs cooler than the GDDR5 version, although both are cool running cards.

It is interesting to see the weakest card on test today, the ASUS GT630 is also the hottest running under load. This is related to the fan setup however, detailed on the next page.
