Gigabyte Radeon HD 7770 OC Video Card Review

Jump To:


Final Thoughts & Conclusions

After spending a couple weeks using the Gigabyte Radeon HD
7770 OC 1GB GDDR5 video card (part number GV-R777OC-1GD) we found it to be a great little video card.  We like that it is faster, quieter and cooler than the AMD Radeon HD 7770 reference card. The fact that it is also about half an inch shorter is also a plus. At the end of the day there is nothing we could find wrong with this card!  It comes nicely equipped and is a very solid graphics card for the price tag.

 Gigabyte Model  Core Clock Memory Clock  Memory Price
 GV-R777D5-1GD  1000 MHz  1125 MHz  1GB GDDR5  $149.99
 GV-R777OC-1GD  1100 MHz  1125 MHz  1GB GDDR5  $159.99


When it comes to price the Gigabyte GV-R777OC-1GD is identical to the GV-R777D5-1GD, with the exception of a 100MHz higher core clock for an extra
$10. You can likely reach this overclock for free by doing it yourself
on the base model, but for those that want to be certain or don’t want
to mess with overclocking, the extra money is usually worth it.

Overclocking the Radeon HD 7770 OC gave us another slight bump in performance, but there isn’t a ton of headroom left in this cards. We managed to get from 1100 to 1160MHz, which is only a 60MHz bump in the core clock. This shouldn’t be a deal breaker for most, but if you wanted to have some overclocking fun you might want to step up to a Radeon HD 7850 when they become available to purchase on March 19th. We were able to take that cards 1024 stream processors from 860MHz to 1050MHz. That isn’t as high as we were able to take the Gigabyte Radeon HD 7770 OC, but remember it has just 640 stream processors and half the ROPs. There is also a $90 price jump as well!

Legit Bottom Line: The Gigabyte Radeon HD 7770 OC is a very well designed video card that features a custom PCB, GPU cooler and is factory overclocked to seal the deal.
