Specifications of the ATI Radeon HD 4550 GDDR3 GPU


ATI Radeon HD 4550 GDDR3 desktop Graphics Processing Unit was introduced in September 2008. The GPU makes use of Unified Superscalar Shader architecture, and it is produced on 55 nm technological process. The card has 600 MHz graphics clock frequency. It also has 80 stream processors, 4 color ROPs, together with 8 texture units. The Radeon HD 4550 GDDR3 incorporates 512 MB of GDDR3 memory. Because the memory operates at 800 MHz, and utilizes 64 bit bus, the effective memory bandwidth is 12.8 GB/s. The GPU supports PCI Express 2.0 interface, and needs 1 motherboard slot. The maximum power draw of this model is 25 Watt.
