AMD Radeon HD 7990 May Launch Late July

AMD's flagship Southern Islands dual-GPU graphics card, Radeon HD 7990, is set to launch in the second half of July, according to various reports. Sporting two Tahiti-XT GPUs, there will be a total of 4096 GCN cores, along with 256 TMU and 64 ROPs, as well as 6 GB of GDDR5 memory for the reference design.

Although clock speeds are not yet confirmed, previous rumors have suggested it will have a core speed of 850 MHz and a memory speed of 1250 MHz (5000 MHz effective). What is known is that the cards will support AMDs new Turbo feature. How this will compare to NVidia's dual-GPU Kepler card, GeForce GTX 690, is not yet known.

The new cards are out being sampled by AIBs and reviewers, for testing prior to the launch. Prices are not yet known, but we expect it to be priced to compete with the GTX 690. We should have more definite specs within the next few weeks.
