XFX R7950 Black Edition Double Dissipation - A Performance Thoroughbred

Launch SRP: S$680

Beyond Skin Deep - More of XFX R7950

Beneath the Double Dissipation Heatsink

Before getting down to performance matters, here's a few more shots of the bare card. Removing the heatsink of the XFX R7950 Black Edition Double Dissipation, we were met with its black PCB (which XFX claims it has 2oz of copper). On its top right hand corner of the card are the two six-pin power connectors. We were half expecting one of them to be an 8-pin power connector which would have allowed the board to have had an increase in power intake if required for more extreme overclocking. In any case, we'll check out how it fares in our overclocking trials soon enough. Back to power matters, XFX recommends using the card with a PSU that's rated at least 500W to run it on your rig. We suggest using a PSU rated 750W and above if you're thinking of setting up a multi-GPU CrossFireX solution.

The PCB of the XFX R7950 Black Edition Double Dissipation graphics card features 2oz of copper, solid capacitors and ferrite core chokers.There are also a total of twelve memory chips surrounding the Tahiti Pro GPU.

 A closeup of the Hynix memory chips reveals its model number - H5GQ2H24MFA. A search on the web showed that the same chips are featured on a number of Cayman GPU-based (Radeon HD 6900 series) graphics cards.

The card sports a CHiL voltage controller, together with its collection of solid capacitors and ferrite cores, make up the VRM solution.

Prior to separating the cooling solution from the PCB of the card, we observed that the heatsink didn't seem to sit properly above a few of the memory chips. Normally we wouldn't be concerned much as the thermal pads act as a decent interface material, but on this card, we saw a couple of memory chips peeking out and not covered by the heatsink nor the thermal pads. For the perfectionists, you may have concerns when the card is used for an extended period of time, but we didn't encounter any in our trials. In any case, we wouldn't be too concerned about it and it's more of an observation we're passing on. To be safe, you might want to avoid overclocking the memory further.

The two Hynix memory chips near the PCIe interface of the card are not fully covered by the heatsink, nor the thermal pads.

The Good
Stellar performance to challenge 7970 GPU
Good cooler design
Thrifty power consumption
The Bad
Heatsink has poor fit over some memory chips
