On the new Radeon X 800, and the GeForce he is already being used 6800 Ultra. The speech is of course the GDDR3 memory, who was able to celebrate his commercial debut in the last few weeks and to convince. But the development is not standing still and so is working now on GDDR4.

This new storage standard for graphics cards to come already at the end of the year on the market and into new regions of the clock. Samsung – one of the first manufacturers that produced GDDR3 memory – talk of speeds of up to 1.4 GHz (2.8 GHz effective) for this new generation of storage. With current GDDR3 devices you would like to achieve 2.0 GHz effective up to – this is said also to be established at the end of the year.

Much like the jump from GDDR2 to 3, the development of GDDR4 is more a technical evolution than a revolution. It is possible, among other things, to provide older graphics chips with the new storage, because the standards are pin compatible with each other. In addition, GDDR3 and GDDR4 set on a similar technique that improves again with the new standard and has been optimized to achieve higher clock rates. Unlike GDDR2, a standard that runs internally only with the half clock frequency, GDDR3 is not so connected. This type of memory internally runs with full time and separated only the “Reads” and “Writes” on the basis of a one-way pipe, bi-directionally does this while runs internally only with half time GDDR2. The development of GDDR4 standard by ATi and nVidia pushing forward.
