XFX HD 5770

The XFX HD 5770 runs at reference clocks - 850MHz GPU and 1200MHz memory. Although the memory interface is 128-bit, pairing it up with GDDR5 results in bandwidth of 76.8GB/s. Unlike the HD 4870 which required two 6-pin connectors, the HD 5770 requires only one. Maximum consumption won't exceed 108W, whereas idle consumption stays at 18W. For comparison, the XFX HD 5750 consumes up to 86W in workload scenarios.

The following photo shows the XFX HD 5770, which looks-wise resembles the faster, HD 5800 series' cards.

Just like on the HD 5750, the HD 5770's memory is evenly distributed (4 modules on the front and on the back). The memory again comes from Hynix.

The XFX HD 5770's dual-slot cooling features a fan towards the end of the card, which pushes hot air towards the I/O panel and out of the case. However, since the video outs take up a lot of space, the outlets are pretty small so some air surely escapes through the card's hood. The card proudly bears the ATI Radeon logo, and you can clearly see some additional air outlets on the photos.

The power connector is hidden in towards the end of the card. We already said that the HD 5770 won't consume more than 108W, so PCI-Express power coupled with an additional 6-pin connector will be enough.

The fan is pretty quiet and the card produced less noise than the HD 5850. The picture below shows the two new HD 5700 cards.
