Verdict

The ATI Radeon HD 5450 is an entry-level graphics card launched in February 2010, built on a 40 nm process with the Cedar graphics processor. It features 80 stream processors, a core clock speed of 650 MHz, and was typically paired with either 512 MB or 1 GB of DDR2 or DDR3 memory on a 64-bit interface. Its primary characteristics include support for DirectX 11, ATI Eyefinity multi-display technology, and a low-profile design that often utilizes passive cooling. Main pros include a very low power consumption of approximately 19W, silent operation for HTPC builds, and hardware-accelerated video decoding (UVD 2.2) with support for HD audio bitstreaming. However, its cons include extremely limited gaming performance even by 2010 standards, narrow 64-bit memory bandwidth, and an inability to handle modern 3D titles effectively.
