Currently NVIDIA is the king of GPUs, but it appears that AMD is getting ready to dethrone NVIDIA with its new Radeon HD 9970. Details about the new card's specifications have been leaked, and, if they are to be believed, they sure are impressive. The Radeon HD 9970 will be using a 20 nm Volcanic Islands GPU codenamed Hawaii that will use a new architecture.
The specifications sure look astounding, maybe a little too astounding compared to NVIDIA's Titan and GTX 780. According to the leak, the Radeon HD 9970 will have a clock speed of 1 GHz, 4 GB of GDDR5 memory clocked at 5 GHz on a 512-bit bus, 307 GB/s memory bandwidth, 64 GPixels, 4,096 shader units, 64 render output processors, and 256 texture mapping units.
The Radeon HD 9000 series is expected to ship around October this year, and according to some reports, the flagship has already started shipping out to manufacturers. If all of this is true, NVIDIA will have its job cut out for it, but it might be wise to take this with a grain of salt as the specifications seem a little too impressive, along with the fact that 20 nm might be further out in the future.
