AMD has the HD 7970 ge lwa site. The video card is equipped with the Tahiti gpu, which uses a new architecture. All the specifications are already leaked, but on 22 december will also be the first reviews online appear.
AMD was the first plan to the HD 7900 series on January 9, during CES, to introduce, but on the 16th of december the introduction of the HD 7970 brought forward to december 22. The HD 7970 is AMD’s new flagship and will, for now, the fastest gpu on board, where the GF110-gpu of Nvidia on the GTX 580 itself, until recently, the fastest gpu could call.
The HD 7970, the Tahiti gpu on board, which has a whopping 2048 stream processors, each with a clock speed of 925MHz. That is good for up to 3,79 Tflops of computing power. The gpu state through a 384bit-memory bus in connection with 3GB gddr5 memory, a clock speed 5.5 GHz. It has AMD’s high-end gpu for the first time a 384bit-memory bus, since the 2900XT, which is more than four years old and, for comparison, about 320 streamprocessors had.
Except over the higher specifications of the Tahiti gpu compared to the HD 6970, was also the architecture is nice on the kick is taken. AMD stepped off of the vliw4 architecture, in which all streamprocessors, which 4 were grouped, the same calculation had to run. If that was not possible, continued to one or more streamprocessors untapped. With the new architecture allows each streamprocessor independently of the other sp’s perform a calculation. This would make the efficiency higher.
According to AMD’s own documentation would be the HD 7970 is between 30 and 60 percent faster than the GTX 580 from Nvidia. The Tahiti gpu has eur 4.31 billion transistors on board, more than 3 billion of Nvidia GF110-gpu. Despite the large amount of transistors to measure the chip just around the 365mm2. The video card would be a maximum of 250W consume. That may increase if the gpu is overclocked; according to AMD are clock speed from 1100 to 1200MHz feasible.
The HD 7970 is now only introduced. The video card will not be until around January 9, in the shops, for a suggested retail price of 550 dollars. How is that to euros translates, is still unclear. Around that time is also the HD 7950 is expected, the smaller brother of the HD 7970.
