Specifications of the AMD Radeon HD 7550M GDDR5 GPU


AMD Radeon HD 7550M GDDR5 mobile Graphics Processing Unit was released in January 2012. The GPU makes use of TeraScale 2 Unified Processing architecture, and it is manufactured on 40 nm technological process. The cards graphics frequency is 450 MHz. It also has 400 stream processors, 20 texture units, as well as 8 color ROPs. The Radeon HD 7550M GDDR5 comes with 1 GB of GDDR5 memory. Because the memory is clocked at 800 MHz, and utilizes 64 bit bus, the effective memory bandwidth is 25.6 GB/s. The GPU supports PCI Express 2.1 interface. This model needs up to 14 Watt of power. To increase AMD Radeon HD 7550M GDDR5 gaming and 3D graphics performance, it can be paired with a similar graphics card in crossfire mode.
