with the launch of the AMD Radeon HD 7700 series, XFX decided to launch no less than nine different models starting with Core Edition based on AMD reference clock and all the way up to SuperOverclock Edition that we had a chance to review today.
The XFX Radeon HD 7770 includes a total of five models that start with XFX HD 7770 Core Edition featuring AMD reference 1000MHz GPU and 4.5GHz memory clocks paired up with XFX's Ghost Technology cooler with a single center placed dust-free IP-5X fan, as well as solid state capacitors and XFX exclusive bracket. The next in line are two cards that are a part of XFX's Standard Edition, the XFX FX-777A-ZDB4 Black Edition Double Dissipation card with a dual-slot dual-fan cooler that is overclocked to 1095MHz for the GPU and 4.98GHz for 1GB of GDDR5 memory and the XFX FX-777A-ZNBC
with Ghost Technology, which is pretty much identical as the Core Edition but with same 1095MHz GPU and 4.98GHz memory overclock.
The Double Dissipation Edition includes a single FX-777A-ZDF4 model that is pretty much the same as the Black Edition one mentioned earlier as it uses the same dual-slot dual-fan cooler but lacks the factory overclock so it is set to work at 1000MHZ for the GPU and 4.5GHz for memory. The last but not least, is the cream of the crop, Black Edition series FX-777A-ZDSC Super Overclock card that we had a chance to review earlier. This one works at impressive 1120MHz for the GPU and 5.2GHz for the same 1GB of GDDR5 memory paired up with a 128-bit memory interface.
The XFX 7750 lineup is pretty much the same but includes "only" four models, Core Edition, Double Dissipation Edition, Black Edition and Black Edition with Double Dissipation. As you could have guessed, both Black Edition cards will feature a factory-overclock that is currently unknown as the core clock is still TBD. The Core Edition and Double Dissipation Edition are both set at 800MHz for the GPU and 4.5GHz for 1GB of GDDR5 memory and are differentiated by the cooler, one with a single fan and other with dual-fan cooler.
The entire XFX lineup is a bit of confussing but thankfully, the XFX site have them all listed in one place and it is easy to find the right model for yourself.
