Move over 5970, the new king of the hill is here. AMD’s top end card, the dual-GPU Antilles or for easier references the Radeon HD 6990 has arrived.
The Radeon HD 6990 is clocked at 830MHz GPU frequency (@1.12v) and 1,250MHz for the memory (5.0Gbps effective data rate) and is equipped with 4GB of on-board frame buffer memory—2GB per GPU, 3072 stream processors enabled, 192 texture units, and 64 ROPs. Added up, that’s about twice the specs of a Radeon HD 6970s (almost as the 6970 cards are clocked at 880MHz). This dual GPU monster has a suprisingly low idle TDP of just 37W and a TDP at load of 375W (lol, it’s a monster card indeed).
