New graphics chip from Trident

With the XP4, Trident presents a graphics chip that should be of particular interest for laptops. The fully DirectX 8.1 compatible chip is satisfied with only 3 watts of power. This power saving is achieved through the use of just 30 million transistors. The performance data, however, speak for themselves: GPU with 250 MHz and memory clock of 333 MHz with fast DDR RAM.

Other features include multi-view, i.e. all outputs can be controlled at the same time, such as monitor, TFT screen and television. The XP4 can provide a maximum resolution of 2048x1536 pixels for the analog and DVI output and 1024x768 for the TV output. Furthermore, the chip should be capable of a kind of 'tile base rendering', which is known from Kyro, in order to save memory bandwidth. With the support of Motion Compensation and iDCT (Inverse Discrete Cosine Transformation) directly by the XP4, the CPU load when playing DVDs should be a maximum of 15 percent. A special power-saving management, which is controlled half by the software and half by the hardware, for example by reducing the clock rate, should significantly extend the battery life.
