AMD launched three IGP chipsets in China on January 23, including the AMD 740G chipset with ATI Radeon 2100 graphics (RS740), AMD 780V chipset with ATI Radeon 3100 graphics (RS780C) and AMD 780G chipset with ATI Radeon HD 3200 graphics (RS780), while the worldwide launch of these products has been postponed to March 5, according to sources at motherboard makers.
The 740G is an upgrade of the previous RS690 chipset and therefore only supports up to DirectX 9, HyperTransport 1.0 and PCI Express (PCIe) 1.1a, but it is pin is compatible with the RS780. The chipset will target entry-level and OEM markets with motherboard pricing set around US$40-60.
The RS780 series includes two versions, the RS780 for performance/mainstream markets and the RS780C targeting lower-end markets. The differences between the two are that RS780C does not support AMD's UVD engine, Hybrid CrossFire technology or local frame buffer memory. RS780C-based motherboards will be priced around US$60-70, while RS780 boards will cost around US$70-90.
The guys at OC Workbench have posted what they say are benchmarks of the RS780G in action. The numbers only compare the RS780G with its predecessor, the 690G, but they nonetheless paint an interesting picture. In F.E.A.R., the RS780G is almost twice as fast as the 690G, scoring 29 FPS over the other contender's 15 FPS. And in 3DMark06, the RS780G scores 1162 points, up almost 400% from the 690g's 321 points. In terms of 3D graphics performance, AMD RS780 is 2x faster than AMD 690G. In 3Dmark06, the difference is shocking, 1162 vs 321. That is 3.6X difference.
AMD also announce new graphic card -- HD 3400 and HD 3600 series. In HD 3400 series, there are some models, like HD 3450 and HD 3470. They will costs around USD 49-65. In HD 3600 series, there is one model -- HD 3650, it will costs USD 79-99.
