The Radeon HD 6450 was an entry-level graphics card by AMD, launched in April 2011. Built on the 40 nm process, and based on the Caicos graphics processor, in its Caicos PRO variant, the card supports DirectX 11.2. The Caicos graphics processor is a relatively small chip with a die area of only 67 mm² and 370 million transistors. It features 160 shading units, 8 texture mapping units, and 4 ROPs. AMD has paired 512 MB GDDR5 memory with the Radeon HD 6450, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 625 MHz, memory is running at 800 MHz (3.2 Gbps effective).
Being a single-slot card, the AMD Radeon HD 6450 does not require any additional power connector, its power draw is rated at 18 W maximum. Display outputs include: 1x DVI, 1x HDMI, 1x VGA. Radeon HD 6450 is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 168 mm in length, and features a single-slot cooling solution. Its price at launch was 55 US Dollars.
