Radeon HD 7550M 1GB GDDR5 Review
Radeon HD 7550M 1GB GDDR5, codenamed 'Thames-Pro', is a mid-range GPU part of the Mobility HD 7000M Series released by AMD in 2012.
It's still based on the old Turks chip and therefore a renamed Radeon HD 6630M but only 400 of the 480 Pipelines are available. The core-clock will range from 450MHz to 550MHz, and will be decided by the laptop manufacturer, probably according to the cooling system and the memory clock with fast GDDR5 will be set to 900MHz. Using fast GDDR5, its performance will be very similar to the Radeon HD 6530M, since it's paired with a 64 bits bus width.
A DDR3 version, codenamed "Thames-LP" is also manufactured.
The performance is very limited and so Very Demanding games (e.g. Metro 2033, Max Payne 3) will only run on the lowest settings and even Demanding games (e.g. Crysis, Mafia 2) might require very reduced settings.
