PowerColor LCS HD7970 3GB GDDR5

As one might guess, the HD 7970 is built around AMD's 28nm Southern Islands Tahiti GPU core. The Tahiti core features AMD's all new GCN architecture to go along with the process shrink. The new core features 4.31 billion transistors, 2048 stream processors,128 texture units, 32 ROPs, and 3GB of GDDR5 memory running through an increased 384-it bus. PowerColor's LCS HD 7970 differs from the normal reference version of this card with the inclusion of the EK-FC7970 full cover waterblock. By partnering with EK to use its high end waterblock, PowerColor is able to run the clock speeds up to 1050MHz on the Tahiti core and 1425MHz on the 3GB of GDDR5 memory, making it the fastest factory offering of an HD 7970 to date.
