AMD Tahiti (Radeon HD 7900) Graphics Card Seen in the Nude

Now this is what I have been waiting for. A good reason to upgrade systems and not just components.

Do want!

I said this once and i'll say it again,

stfu already and take my money

Is it just me, or does this card only have an electrical 8x PCIe connection in a physical 16x one because of that 12th memory chip?

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.

That might be why they are using 2 PCIe power connectors.

Might be PCIe 3.0 @ 8x aswell, it's the same bandwidth as 2.0 @ 16x

That GPU bracket looks awesome. Direct contact with the cooler is just freaking great. Makes your lapping even more efective and it avoids core cracking. Soo sexy design.

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.
