1120MHz Overclocked Radeon HD 7770 Announced by XFX

Just moments after the official introduction of the Radeon DH 7700 series, XFX announced a new range of graphics card based on this design, including the SuperOverclock Edition HD 7770 which was built in order to work at a whopping 1120MHz.

It goes without saying that this is XFX’ most powerful solution to be released in the HD 7700 series, which includes no less than 9 graphics cards.

Much like the company’s factory overclocked HD 7900, the HD7770 Super Clocked utilizes the same “dual dissipation” cooler design that relies on two large diameter fans to push away the heat produced by the card while running.

Thanks to this advanced cooling setup,XFX was able to push AMD’s graphics card over its reference frequencies and clocked the GPU at an impressive 1120MHz, while the memory now works at 1300MHz (5.2GHz data rate).

To put things in perspective, AMD’s recommended operating frequencies for the Radeon HD 7770 are set at 1000MHz for the GPU and 1.125GHz (4.5GHz effective) for the memory.

Officially introduced earlier today, AMD’s Radeon HD 7770 graphics card is based on the same Graphics Core Next architecture as the HD 7900 series.
At the heart of this new AMD creation stands, however, an entirely new GPU, dubbed Cape Verde,which is made up of 10 Compute Units to deliver a total of 640 stream processors and 40 texture units.

These are packed together with 16 ROP units, one geometry engine/rasterizer and 512KB of L2 cache, as well as with a 128-bit wide memory bus connected to 1GB of GDDR5 video buffer.
AMD’s recommended price for the Radeon HD 7770 is set at $159 (about 121 EUR), while the XFX SuperOverclock Edition retails for $179.99 (136 EUR).
XFX’ Radeon HD 7770 graphics card range includes three other models, two of them featuring the Double Dissipation cooler.
