To detach the cooler from the graphics card a total of just six screws need to be removed from the backplate. After removing the heatsink we can clearly see the Ghost 3.0+ design which makes use of two large heatsinks and a plethora of thick copper heatpipes.


Having detached the cooler from the graphics card we can now see the PCB in-the-flesh and the additional heatsinks which XFX has placed over key areas. Over the memory there is a large plate which is fixed via screws – underneath this plate there are thermal pads to assist with heat dissipation. Covering the VRMs there is also a heatsink configuration which will deliver optimum cooling for these components.


At the very heart of 390X we have the Grenada XT GPU. This is the same design as the 290X (Hawaii XT) – the same circuitary and design but with better manufacturing. Many were hoping for a bigger step-up from this but the 300 series has only had a minor facelift.


Dotted around the PCB we have 16x 512MB GDDR5 chips courtesy of Hynix (H5GC4H24AJR T2C). The memory on our card operates at 6000MHz. Another thing to note is that XFX has made use of Japanese Solid CAPs for long-life usage.


As an additional feature, XFX has given 390X DD a dual-BIOS switch, allowing you to choose between two different modes and effectively have a back-up should anything go pear-shaped.
