WCCFtech's "history" of being wrong:
http://wccftech.com/amds-generation-radeon-hd-7970-gpus-performance-comparable-hd-6990/
The HD 7970/7950 are expected to use the XDR2 memory which would provide double the memory bandwidth when compared to GDDR5, 6Gbit/s (GDDR5) Vs 12.8Gbit/s (XDR2) while reducing the total power consumption to nearly 30%, This means that the card would not only perform better but also feature better Power/Thermal efficiency then previous HD 6000 Series cores.
XDR2 was previously confirmed by AMD Radeon's only functional Twitter Account

Following are specifications of the Radeon HD 7970:
- PCI-Express 3.0
- GPU: 2048 shader processors @ 1000MHz, 28nm TSMC
- Memory: 3GB GDDR5 (384-bit)
- Texture units: 128
- ROPs: 64
- Power consumption: 190W 210W TDP
That's a 10% perform difference compared to HD6990 which can be overcome by a minor overclock. WCCFtech didn't say that the performance was equivalent to the HD6990, Its comparable.
Sapphire's planning to launch their Atomic RX/WC series cards with 6GB memory and 1335Mhz Clock speeds which will most likely perform near the 699 0 levels.
Wrong again

These are the first pictures of the Radeon HD7970 to surface on the internet in detail. The final production PCB on the 7970 will be in an all black color hence this is proven to be an engineering sample. The photo depicts two 6 pin connectors as compared to earlier rumored 8 pin connectors on the cards PCB.
The 7970 utilizes a digital-PWN design that has single-phase PWM chokes, and regulators made by Volterra. There are also 5+1+1 Phase VRMs along with analog power domains.
WRONG
I don't see anything wrong with this post. The specs are the same as of a reference HD7970 model, Only thing different in the pictures is the 2 x 6 pin connectors and a Red PCB. That's because the card they pictured was in
Engineering Phase, Not the retail variant.
