The first 40- nm RV740 processor will be used in radeon HD 4770.
Today appeared new slides from AMD road map, which reveal information relative to the future budget video cards.
Focus attention on the technical characteristics of radeon HD 4770 video cards. According to the represented information, the graphic processor microcircuit will consist on 826 million transistors, the core operating frequency , in comparison with the model HD 4570, will remain as before, 750 MHz. Then the quantity of stream processor will be increased by twice , up to 640 pieces.
The radeon HD 4770 will be equipped with GDDR5 memory microcircuits , which function at the frequency 800 MHz, and the total volume of installed memory will be 512 mb. The memory bus will be limited to 128 bits.
New AMD card will not only increase the computational possibilities of his devices, but also will increase the energy consumption of those video cards. Radeon HD 4770 will consume about 80 watts.
