I'm pretty sure those are mini-Displayports.Display connectivity options include one DVI port, one full-sized HDMI port, and two mini-HDMI ports. You may use all the outputs at the same time.

So as chip die size doesnt match as you mentioned, coul we guesstimate thta this aint real Tahiti rejects but instead full blow new chip that is just branded by web/OEMs as TahitiLE??AMD's Tahiti graphics processor introduced the GCN shader architecture. It is also the first GPU to be produced on a 28 nm process at TSMC. The transistor count is 4.31 billion.
Please note that the package of the GPU is completely different to that of the regular Tahiti GPU. Regular Tahiti has a bigger substrate (green stuff), and the metal shim extends much closer to the GPU die. The Tahiti LE also has laser-etched writing on the die, while regular Tahiti GPUs are completely clean.
