ATI Radeon HD 4770 from the AMD
the AMD announced the first GPU in the world that is manufactured with method of completion 40nm, and which constitutes the motive force of new ATI Radeon HD 4770. A lot of constructors already have announced their own models that are based in last generation GPU of AMD and that moreover, make use of second generation of memory of type GDDR5.
new ATI Radeon HD 4770 is based on 40nm GPU of AMD, RV740, who is constituted by 826 millions transistors, 640 stream processors and offers calculating force 900GigaFLOPs.
the core has frequency of operation 750MHz and it allocates 32 TMUs (Texture Memory Units) and 16 ROPs (Raster Operation Pixel Pipelines) while memory interface it allocates breadth of 128-bit. The cards of type will incorporate 512MB memory GDDR5 (800MHz, that is to say 3200MHz Quad Data Rate) however are not excluded they circulate models that incorporate and 1GB of memory.
Naturally, is compatible with DirectX 10. 1 while it supports inter alia also technology ATI CrossfireX. Her basic competitor is Nvidia Geforce 9800 GT. More for the specifications you can read here. Polloy constructors already have announced models that are based on core RV740, in between them Sapphire, the ASUS, Gigabyte, PowerColor, GeCube Mr a.
