HKEPC has posted some information about AMD's upcoming RS780 and RS740 chipsets and we're looking at a range of new IGP names from AMD this time around. Starting with the most well known model, the plain and simple RS780 which will be known as tha AMD 780G chipset when it launches will have a graphics core known as the ATI Radeon HD 3200. It supports UVD, DX10, HyperTransport 3.0 and PCIe 2.0 and maybe most importantly Hybrid CrossFire.
The next version down is the RS780C or the AMD 780V which will replace the current 680V. The graphics core on this card will be known as the ATI Radeon 3100. No, that's not a typo, as this graphics core doesn't have UVD support, hence the lack of the word HD in the model name, the rest of the features are similar to the RS780, but it lacks support for Hybrid CrossFire and the GPU will most likely be clocked slower.
The most basic IGP chipset will be the RS740 which will launch after the RS780 and it will be known as the AMD 740G chipset and its graphics core will go under the name of ATI Radeon 2100. This is a DX9 part and it will only support HyperTransport 1.0 and PCIe 1.1a.
Finally we have the top of the range model, the RS780D or AMD 790GX chipset. The graphics core will go under the name of ATI Radeon HD 3200 and this chipset will have support for all of the features of the RS780, but it also adds support for dual x8 CrossFire.
