The ATI Radeon HD 4770

Boosting a 40nm GPU, which should lead to cooler operating temperatures, and as a mid-range card a step up from the Radeon HD 4670, we were expecting the new Radeon HD 4770 to be a single-slot card. We were wrong. The new HD 4770 is in fact a double-slot card, and sports the a similar cooler to what we've seen on reference HD 4870 and HD 4890 cards.

We thought this was particularly worrying and we suspect that ATI decided to go with a dual-slot only because the card runs pretty warm. Furthermore, it is also worth mentioning that the cooler suffers from periodic moments when it revs up the fan. It's probably nothing to worry about and more of a software and driver issue, but it does get annoying from time to time.

Our card comes with reference clock speeds, which means clock speeds of 750MHz at the core and stream processors and a memory running at 3200MHz DDR. Here are some closer shots of it.
