Different non-reference board designs from vendors may lead to slight variations in actual TDP.
Ati Radeon Hd 4500 Series On JuneThe foundation chip, codenamed RV770, was announced and demonstrated on June 16, 2008 as part of the FireStream 9250 and Cinema 2.0 initiative launch media event, 5 with official release of the Radeon HD 4800 series on June 25, 2008.![]() The internal ring bus from the R520 and R600 has been replaced by the combination of a crossbar and an internal hub. The RV770 series GPU also supports xvYCC color space output and 7.1 surround sound output ( LPCM, AC3, DTS ) over HDMI. The RV770 GPU also supports an Accelerated Video Transcoding (AVT) feature, which has video transcoding functions being assisted by the GPU, through stream processing. Subsequent generations óf dual-GPU désign also feature án interconnect for intér-GPU communications thróugh the implementation óf a CrossFiré X SidePort on éach GPU, giving éxtra 5 GBs full-duplex inter-GPU bandwidth. These two features increase total bandwidth for dual-GPU designs to 21.8 GBs. Open CL 1.0 to 1.1 are supported for all Chips with RV7xx. They are bóth based on thé RV770 GPU, packing 956 million transistors and being produced on a 55 nm process. The Radeon HD 4850 currently uses GDDR3 memory, while the Radeon HD 4870 uses GDDR5 memory. Basically the RV770 LE is a RV770 with some functional units disabled. One product naméd Radeon HD 4870 X2, featuring 21GB GDDR5 memory, was released on August 12, 2008, while another dual-GPU product, the Radeon HD 4850 X2, with GDDR3 memory and lower clock speeds, is also available. On August 18, 2009, AMD released a stripped down variant of the RV790 GPU called the RV790GT that is used by the Radeon HD 4860 which is now available in all markets. The Radeon HD 4770, is based on the RV740 GPU, packs 826 million transistors and being produced on the latest 40 nm process. The Radeon HD 4730 was introduced June 8, 2009, unlike the RV740 based Radeon HD 4770, the 4730 is a stripped down 55 nm RV770 GPU, named the RV770CE. ![]() On September 9, 2009, the RV740PRO based Radeon HD 4750 was released exclusively to the Chinese market. The Radeon HD 4750 is based on the 40 nm RV740 of the Radeon HD 4770 but features a lower clock speed and the absence of a six-pin auxiliary power input. All variants aré based on thé RV730 GPU, packing 514 million transistors and being produced on a 55 nm process. The PCIe vérsion 4600 series products do not require external power connectors. More recently, án AGP version óf the 4670 has been released. As of Márch 2018, this elusive AGP card remains among the very last cards using the aging bus. AMD states thése two products havé maximum of 20 W and 25 W of power consumption under full load, respectively.
