The Radeon HD 4850 presently uses GDDR3 storage, while the Radeon HD 4870 uses GDDR5 memory space.īasically the RV770 LE can be a RV770 with some functional units disabled. They are both based on the Mobile home770 GPU, packing 956 million transistors and getting produced on a 55 nm procedure. Open CL 1.0 to 1.1 are usually supported for all Potato chips with Mobile home7xx. These two features increase overall bandwidth for dual-GPU styles to 21.8 GBs. Subsequent years of dual-GPU style also feature an interconnect fór inter-GPU communications through the execution of a CrossFire A SidePort on each GPU, offering extra 5 GBs full-duplex inter-GPU bandwidth. The RV770 GPU also supports an Accelerated Movie Transcoding (AVT) feature, which offers video transcoding features being helped by the GPU, through flow processing. The RV770 series GPU also facilitates xvYCC colour space result and 7.1 surround audio output ( LPCM, Air cooling3, DTS ) over HDMI. The internal ring shuttle bus from the Ur520 and R600 offers been replaced by the combination of a cróssbar and an inner hub. The RV770 furthermore provides 10 texture devices, each of which can handle 4 handles, 16 FP32 examples, and 4 FP32 filtering features per clock routine. The RV770 keeps the Ur600s 4 Quad ROP bunch count, however, they are faster and right now have devoted hardware-based AA deal with in inclusion to the shader-based take care of of the Ur600 structures.
