Radeon HD 7550M Game Requirement Analysis
Radeon HD 7550M is an Entry-Level Mobile Graphics Card based on the second revision of the Terascale Architecture.
The Second variant of the Terascale 2 Architecture is still manufactured with a 40nm technology and despite allowing more Stream Cores, their design remains more or less the same compared to the first variant.
It equips a GPU codenamed Thames PRO which has 6 Compute Units activated and thus offers 480 Shader Processing Units, 24 TMUs and 8 ROPs. The Central Unit runs at 500MHz.
The GPU accesses a 2GB frame buffer of DDR3, through a 64-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The memory clock operates at 900MHz.
DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, HD3D, Eyefinity, App Acceleration, PowerPlay and other technologies.
With a rated board TDP of 14W, it is suited for average sized laptops.
Gaming benchmarks put its performance somewhere on average with GeForce GT 425M.
We recommend a modest processor (Intel Core i3 Mobile and 4GB of RAM for a system with Radeon HD 7550M.
