Not long after the first pictures of AMD's Tahiti leaked, we have a detailed shot of Tahiti's PCB, which reveals more details. The 12 memory chips are clearly visible, confirming the 384-bit memory bus. It also offers a first glimpse at the Tahiti die.

The card most likely features 1.5 GB GDDR5. The 5+1 phase PWM is also visible. Most importantly, we get the first glimpse of the Tahiti die. It is rotated by 45 degrees and covered by a partial heatspreader. However, the die itself is exposed to the heatsink. Tahiti is a big chip – at first glance a similar size to Cayman. However, it is still visibly much smaller than NVIDIA's previous flagships, GF100/GF110 or GT200/GT200b, so AMD continues to dismiss NVIDIA's big die strategy. 

The card features 2x CF connectors as well as the dual BIOS switched introduced with the HD 6900 series.

There is a crucial difference from the previous leak – this sample consists of 2 x 6-pin PCI-e connectors, as opposed to the 8-pin + 6-pin configuration previously captured. This could suggest that this is either an advanced production ready sample, or Tahiti Pro, or HD 7950, which should feature a lower TDP than Tahiti XT / HD 7970. This card thus has a TDP somewhere between 150W and 225W.
