After the first photos on the web were, are now the first specifications leaked from AMD’s new high-end graphics card, the HD 7970. The gpu has 2048 alu’s with a clock speed of 925MHz, in combination with a 384bit-memory bus.
The slide by obr-hardware online was taken speaks of 3.5 Tflops of computing power. The gpu would be able to do so by the presence of 2048 alu’s, which has a clock speed of 925MHz. An important detail is that the gpu uses the previously-announced Graphics Core Next architecture and not the vliw4 architecture that AMD uses for its HD 6970 and HD 6950.
The gpu features 128 texture units and 32 rop’s. The gpu communicates by means of a 384bit-memory bus with 3GB of gddr5 memory, a clock speed 5.5 GHz. The presence of 32 rop’s in combination with a 384bit-memory bus is weird. In previous generations, had each memory controller four rops, but with twelve geheugencontrollers there would not be 32, but 48 rops must be present.
The video card would be less than 300W consume under load, while idle-power consumption only 3W, it would amount to. This would be because of a new technology called ZeroCore Power, which would take effect if the video card is a long period of time. What video outputs are concerned, offers the HD 7970 on a single dvi port, a hdmi port and two mini-displayports. According to the slide runs to the embargo on 9 January 2012. At that time, so we can probably expect more.
