Four chips in 6 months reaches its end today, with the launch of the final chip in AMD’s Evergreen stack: "Cedar". Cedar, the baby of the family, will be powering AMD’s bottom-tier cards. Today we’re seeing the the first of what we expect will be a couple of Cedar cards with the launch of the Radeon HD 5450. The ATI Radeon HD 5450 graphics card delivers a state-of-the-art HD multimedia and game experience at a value price. You can expect to find listed soon for $49-59.
The Radeon HD 5450 has 292 million transistors, 80 stream processors, two texture units (each capable of filtering four texels per clock cycle), and a single ROP that can push out four pixels per clock. Radeon HD 5450 graphics cards will have a 650MHz core clock speed, up to 1GB of DDR2 or DDR3 memory with a 1.8Gbps top data rate, and 64-bit memory interfaces. (The $49 part will only have 512MB of RAM, however.)
