Gigabyte HD6770 Silent Cell 1GB Review (passively cooled)

The Gigabyte HD6770 Silent Cell ships in a dull looking box with a huge window cut out at the front – to expose the radical heatsink design.

The bundle includes a software disc, literature on the product, a video converter, power converter and Crossfire Cable. There are no free games bundled with this particular card.

The card is built around a striking blue PCB, and the giant heatsink overhangs the card by a considerable margin.

The card demands a single 6 pin PCI E power connector, which is positioned between the rows of overhanging aluminum heatsinks.

The Gigabyte card ships with three full sized connectors – DVI, HDMI and Displayport. Covering the full gamut of digital connectivity. The heatsink fins poke through the dual slot backplate.

There is 1GB of Hynix H5GQ1H24AFR memory onboard.

The Gigabyte card is a really attractive design, and we don't often say that about passively cooled cards. The company branding is apparent on both surfaces of the dual width heatsink.

The cooler is held in place with four screws, which are easily removed.

The cooler design is complex, with multiple racks of aluminum fins all connected to the core block via heatpipes.

The GPU core runs at 850mhz, and the 1GB of GDDR5 memory is clocked at 1200mhz (4800mhz effective) – this is connected via a 128bit memory interface. The HD6770 has 16 ROP's and 800 unified shaders.

  1. The design is great, I love passive cards and am willing to forgo a little performance. I must be really sensitive against fan noise as even my system with bequiet fans annoys me. im going to check this out. thanks.

  2. I really do like this, if they could get the price down by £15 it would be a must have IMO

  3. Its a bit weak for my needs, but I can see why people would like the whole ‘no noise’ deal. there aren’t enough silent cards made. Wonder if they could ever get a 6870 silent. I might opt for that one.

  4. I own a HD5770 and I saw this today, im impressed with the cooler. have my own card on ebay now, hopefully can fund for half of this one for my media/main pc.

  5. Interesting to see how such a low end card by todays standards can still power many engines at 1080p. As the reviewer said this was never possible in the past. 720p was a stretch.

    Good read. cooler is very strong by the results also.

  6. Not really my thing, but my friend would be into this as he is always bitchin about noise from his computer. he spent £30 on high quality case fans recently. I can’t tell the difference but he is happy.

  7. Well… this is embarrassing. The Gigabyte branding would be upside down if this card were mounted in a conventional tower chassis, I was really interested in the card until I noticed this. I’m mildly OCD so that would be unbearable to live with (I have a windowed Chassis).

    Hopefully they sort that out.

  8. @Trevor, wouldn’t you be better off just getting a custom cooler for your 5770? Seeing as 5770s and 6770s are virtually identical it would save you some money.
