So the 7700 series video adapters had the following core configurations: The main contribution to performance is made by UWB. the number of rasterization blocks (BR).the number of unified shader processors (UWP).The main differences within the series were in the configuration of the cores. The “junior” adapters in the series differed from the “senior” ones only in the number of processors per chip.Īttention! On AMD cards, the core configuration is described by three numbers: Read Graphics Card Features, Characteristics, Types. power consumption – from 47 to 85 watts.Īt the time of its appearance, these cards met the most modern requirements for hardware and software compatibility with all existing means for creating computing systems at that time.hardware API support – Direct X 11.1, partially 12.0 OpenGl – 4.2 OpenCl – 1.2.Overclocking AMD Radeon HD 7700 series AMD Radeon HD 7700 series specificationsĪMD Radeon HD 7700 series cards have the following features:.Radeon HD 7700 Series Graphics Accelerators.AMD Radeon HD 7700 series specifications.Therefore, until now, many AMD fans recall with horror the period when, having confused only two digits in the adapter index, it was possible to seriously miscalculate the performance. For example, the performance of the 79 differed by more than three times and the performances of the 77 were almost the same. To some extent, this made the 7700 series universal, since, on the one hand, the buyer could choose the performance he was interested in by purchasing a particular adapter. On the other hand, the presence of as many as 4 models with the same filling made a lot of confusion in the classification of video adapters.Ī similar confusion persisted in the next generation of AMD products – the R200 family, and only a couple of years later, with the advent of the R400, the situation with the classification improved markedly. The explanation was quite simple: the models differed significantly in the number of unified shader processors. Of the entire HD 7xxx series, only the 7700 had this feature.
