AMD Radeon HD 7900 'Tahiti' snapped
While both GPU camps are hard at work at next-generation DX11.1 (hopefully) graphics cards, AMD’s flagship card, codenamed ‘Tahiti’ was snapped a few days back and today we have a much clearer shot of the card’s PCB, without the heatsink.
Looking at the card, we can now say for certain than AMD will use a 384-bit memory bus, which is evident from the 12 memory chips on board. We also get a clearer shot of the die this time around. The card will most likely feature 1.5GB of GDDR5 memory, although the frequency is still unknown. It will also sport a 5+1 phase PWM for better power management. The die itself is exposed much, like other AMD cards and quite unlike Nvidia who use a heat spreader over the die. We also see two CrossFire connectors, which mean it would be compatible with a four card configuration.
The second picture reveals two 6-pin connectors, instead of the previously snapped 6 plus 8-pin connectors. This could very well be a lower-end variant of Tahiti, a HD 7950 if you will. This also means the TDP should be much lower. That’s all we have for now, but at least we know this much is certain, AMD is making good progress and hopefully are on schedule for a 2012 launch.
