Graphics for the Recession - ATI Radeon HD 4770

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.

The ATI Radeon HD 4770 is like a stockier version of the HD 4850, and like all reference ATI cards, it is decked in red and sports the familiar dual-slot cooler that we have seen on many of its cards.

Our first impressions of the ATI Radeon HD 4770 was that it was a shorter, but stockier, more muscular version of the HD 4850. Will it dethrone the HD 4850 as the most bang-for-buck graphics card? We shall soon find out.

In terms of video outputs, the Radeon HD 4770 comes with the standard twin DVI ports and a single 7-pin mini-DIN.

The dual-slot cooler on the Radeon HD 4770 has copper heat pipes and fins to help dissipate heat. Also note the two CrossFire connectors at the rightmost section of the card.
