AMD Tahiti (Radeon HD 7900) Graphics Card Seen in the Nude
Today may be a Fringe-less Friday but worry not, there are plenty of thing to do like contemplating the two recently-leaked images of an AMD Tahiti-powered graphics card. Tahiti is a 'next-gen' GPU built on TSMC's 28 nm process that's supposed to be at the heart of the Radeon HD 7900 series models (the HD 7950, HD 7970, and then probably the dual-GPU HD 7990).
The card seen below comes with one Tahiti chip protected by a heatspreader/shield (only the die is exposed) and has a red PCB, a 5+1-phase PWM, two BIOSes, two PCIe power plugs, CrossFire connectors enabling quad-GPU configurations, and 12 memory chips which support previous reports of a 384-bit memory interface.
The Radeon HD 7900 series cards are rumored to debut in January at CES 2012 (January 10-13) so we still have one month of leaks to look forward to. Oh, and the winter holidays.

stfu already and take my money
There are not enough traces for a 16x electrical connection. They could be traced on another layer, but it's rare to have traces directly under a memory chip, they are easily influenced at the very high frequency they operate.
As for the 8x electrical PCIe, the tracks can go through the other side, so it should be 16x both on PCIe 2.0 and PCIe 3.0. It would be kind of stupid to not to that, only Sandy Bridge-E and Ivy Bridge are supporting PCIe 3.0, and their cards would not be enough to push for PCIe 3.0 and/or force people to buy new motherboards.
If I had the money, they would take it from my burning pocket.
