AMD Radeon HD 7990 Clock Speeds

AMD logoClosely trailing the launch of NVIDIA's GeForce GTX 680, and keeping up with its own streak of launching a new graphics card line each month since January, AMD will unveil its Radeon HD 7990 graphics card in April, or so it's reported. INPAI reports the clock-speed and chip-configuration of the upcoming dual-GPU monstrosity. The Radeon HD 7990 packs two 28 nm "Tahiti" GPUs as a "Crossfire on a stick" solution. The Tahiti chips will be clocked at 850 MHz (core), and 1250 MHz (5.00 GHz effective) memory.

The chip-configuration of each of the two Tahiti chips will be the same as that on the Radeon HD 7970, with 2048 Graphics CoreNext stream processors, 128 TMUs, 32 ROPs, and 384-bit wide GDDR5 memory interface, holding 3 GB of memory, each. The total memory on the card will hence be 6 GB. With the Radeon HD 7970 refusing to budge from its US $549 price-point, it's quite natural that the Radeon HD 7990 will be priced very high. It is gunning to retain the performance crown that's currently disputed between the Radeon HD 6990 and GeForce GTX 590.
