ATI Radeon HD 4550 Specifications Detailed
 

Hardware-Infos compared the specs of current and next gen entry level 3D cards from ATI:

The chip will possess two SIMD blocks, in which in each case eight Shaderkerne as well as a texture cluster are. The number of harming purities amounts therefore to 16 5D-Einheiten and/or 80 Streamprozessoren, the number of TMUs to eight, because per texture cluster in each case four texture units are available.

The memory interface is for this price segment usually only 64 bit-broadly. 800 MHz fast GDDR3-Speicher tries to some extent to compensate this disadvantage and/or help the hp 4550 to a relatively good memory range of 12,8 GB/s. The chip is addressed with 600 MHz and reached thus a theoretical Texelfüllrate of 4.800 MT/s as well as a theoretical aluminum achievement of 96 Gflops. The following table gives further highlights:
