GIGABYTE Unveils its Radeon HD 7700 Series

GIGABYTE kicked off its Radeon HD 7700 series with a trio of graphics cards, the Radeon HD 7770 GV-R777D5-1GD (AMD reference speeds), the Radeon HD 7770 GV-R777OC-1GD (factory overclocked speeds of 1100 MHz core, 4.50 GHz memory), and the Radeon HD 7750 GV-R775OC-1GI (factory overclocked speeds of 880 MHz core, 4.50 GHz memory). The company didn't release a reference-speed Radeon HD 7750. All three cards are based on non-reference board designs by Gigabyte, consisting of Ulra Durable VGA+ PCBs and optimized large-fan (translates to lower RPM, lower noise) fan-heatsinks.

I'm pleased to see "oversized" (ie. bigger than the card height) cooling. Not only does it allow quieter operation, it also blows the air beyond the card and around the case. So it improves air circulation and cooling all around, esp. in full (populated) PCs.

Is the PCB and power circuitry of the standard and OC editions the same? Do you get more for your money, or only a tweaked bios? (Which we can all do by software or by firmware editing tools)

I too love large single fans :) Even better though is a passive solution with a large fan strapped to it!

I've found that the difference in price between the 6750 and 6770 series is negligible. Likely the same for the 7xxx series. No sense in opting for the 7750 over the 7770. Save yourself headache.

$100 vs. $150.

7750 no power connector needed.

7750 (to be) available as a single slot solution.

Possible bios mods to 7750 to unlock some shaders (pure speculation based on history, could be totally wrong on this one)

7750 crossfired is more notably cheaper than 7770 crossfired. And offers more outputs and greater performance than a single 7770.

I can see a few usage and budget scenarios where a 7750 could be chosen over 7770.

Ah I was just coming back to edit my comment. Good writeup at Anandtech. Colour me surprised to see a 50% price difference.

Thanks for the correction.
