Gigabyte improves the stock clocks of AMD's HD 7770

Over the years, Gigabyte has accustomed us with its non-reference graphics cards and the company's recent Radeon HD 7770 based solution is no exception to this rule, as it comes with a beefier cooling solution and a slightly overclocked GPU.

The card is officially named the GV-R777OC-1GD and Gigabyte states that it improves the AMD reference design to deliver better cooling, higher overclocking headroom and a longer lifespan.

In order to do so, Gigabyte installed on top of the Cape Verde XT GPU a large aluminum heatsink topped by a 100mm diameter fan, specially designed to increase the airflow provided to the card, without increasing the noise generated while running.

In addition, this design also ensures that some of the resulting airflow is pushed towards the card's PCB where it should reach its VRMs and memory chips.

Speaking of memory, Gigabyte has decided to pair the GV-R777OC-1GD with 1GB of DDR5 video buffer, which operates at 1,125MHz (5,500MHz data rate). The GPU is run at 1100MHz, 100MHz higher than AMD's reference clock.

Going to the back of Gigabyte's creation, we get to see that the Taiwanese company has decided to go with its standard video output arrangement for midrange GPUS, which comprises a DVI, a D-Sub, and a gold-plated HDMI port.

The Gigabyte GV-R777OC-1GD should be available right as we speak, but so far the company hasn’t released any info detailing the price of this graphics card.

The Radeon HD 7770 is AMD's latest mainstream card and is based on the Cape Verde XT core, which includes 640 streaming units, 40 texturing units, 16 ROP units and a 128-bit memory bus.

The load TDP is estimated at 80W, so it can be powered using a single PCI Express 6-pin connector.
