AMD pushed back the Radeon HD 7950 3GB GPU launch a few weeks to enable partners to have plentiful stock in the channel. The slight lull between ‘Tahiti’ cards also provides an opportunity for add-in board (AIB) companies to release custom designs, complete with bountiful overclocking, if our reference card results are anything to go by.
In concert with the reference review, first up for us is XFX. Don’t be surprised if the card looks familiar to you; it’s the same cooler as found on the 7970 Double Dissipation model.
In a nutshell, the cooler doesn’t enclose the underlying heatpipe-assisted heatsink. Rather, it’s left to float over it, leaving plenty of room for air to circulate around the card. XFX reckons this setup provides superior airflow venting through the card rather than channeling it all out of the back, as is the case with most modern high-end GPUs.
The PCB itself is similar, though not identical, to the reference card’s; it’s a touch shorter but the overhang of the heatsink makes this card practically the same size, coming in at just over 11in long. This particular version is known as a Black Edition, where there’s been generous overclocking for both the core and memory, and this bad boy chimes in at 900MHz core and 5,500MHz memory, almost matching Radeon HD 7970 speeds and well above what AMD mandates for a basic HD 7950.
