Check out our preview of the GIGABYTE HD 7770 video card, and stay tuned for the actual review!
The GIGABYTE HD 7770
The AMD HD 7000 series is here, with a brand new chip and a new design. The HD 7000 is the latest series of graphics cards just released by AMD, and carries a new graphics processing architecture called Southern Islands. When it was first announced, Southern Islands was rumored to be just a die shrink of the platform used by the HD 6900 series (Cayman).
However, it soon became clear that it was its own architecture, and was intended to compete with Nvidia’s successor to the GeForce 500 series. There has yet been no official announcement from Nvidia regarding the next line of GeForce GPU’s, codenamed Kepler. However, AMD’s release of the HD 7000 series will surely motivate them further.
The card we’re previewing today is the HD 7770 from GIGABYTE. The HD 7770 is a midrange card using a 28nm fabrication process, and is codenamed Cape Verde XT. The HD 7770 is rumored to carry approximately 1.5 billion transistors and has complete support for the PCI-Express 3.0 standard.

Using high quality components on graphics cards is the key factor for having a long lasting, stable and reliable product. GIGABYTE is again setting a new standard by using Ferrite Core Chokes, Low RDS (on) MOSFET and Lower ESR Solid Capacitors, providing the stability and reliability from their high-end graphics solution. In addition, GIGABYTE Ultra Durable 2 Edition graphics cards now feature a sophisticated layout topology. This state-of-the-art power design from GIGABYTE delivers the ideal integration of thermal, electric characteristics, digital signals, power circuitry and optimum placement of components for enhanced graphics performance.
Ultra Cooling – Low RDS(on) MOSFET Design
Low Power Loss – Ferrite Core Choke Design
Longer Life – All-Solid Capacitor Design
Gold plated, durable large contact area connectors have been used for optimum signal transfer between connections
As opposed to the stereotype, GIGABYTE is able to maximize fan size to 10cm with the latest cooling design. With a 10cm fan, the card is virtually silent that its noise level runs much lower
