Sapphire Radeon HD 7770 Overclocked Video Card

Sapphire Radeon HD 7770Based on the Cape Verde XT chipset, the HD 7770 features 640 streaming processors and 1GHz of GDDR5 memory with a 128 bit bus looks to be in close competition of the older Radeon HD 6850 series. We will now put the card through its paces and see just how well it does.


The new Radeon HD 7770 numbers are well within what we figured it would sit. The performance is better than of the older generation Radeon HD 6770. And pricing around the $179 neighborhood it isn’t too bad of an investment if you are stilling running a 6770 or even an Nvidia 550. Or you can opt for the lesser price non-overclocked version for $20 cheaper.

While the performance numbers are really nice, we also like the noise…well lack of noise from the Sapphire model we reviewed here today. At idle you could barely hear it over the other computer components. And when a idle was lit under it, it did get a little louder but nothing we would consider loud.

Sapphire provides you with a slight overclock over the reference specifications. At 150MHz and 125MHz overclocks on the Core and Memory respectfully gives the customer some performance boost without spending much more money and not having to do it themselves.

And for those looking for next generation features the Radeon HD 7770 has PCI 3.0 and DirectX 11.1 support.
