Fast, cool, and cheap are characteristics we like to see in a video card, and the Radeon HD 4770 clearly boasts all three.
Introduction
When AMD announced its attention to focus on mainstream graphics processors, we thought the manufacturer was nuts. Why surrender the top end of the market to arch-rival Nvidia? It took a year, but AMD proved us wrong: The Radeon HD 4770 delivers the best price/performance ratio we’ve seen in a very long time.
How did AMD pack so much performance in a chip that can be mounted on a video card with 512MB of GDDR5 memory that sells for just over a hundred bucks? The company’s engineers took advantage of a new 40nm manufacturing process at the chip foundry TSMC to create an entirely new graphics processor: The RV740. This process enabled them to pack the RV740’s transistors extremely close together, resulting in a chip that’s nearly as powerful as AMD’s costlier Radeon HD 4850, despite being almost half its size.
