...featuring ATI Radeon Xpress 1250 graphics
HKEPC has revealed further details on
the upcoming AMD RS690 chipset. The new chipset has been named AMD 690G and falls in
line with AMD’s new chipset naming scheme. RS690 was previously expected to
be named Radeon Xpress 1200 before AMD and ATI merged.
It appears the AMD 690G is nearly finished with the latest stepping being A12.
Manufacturing of the AMD 690G will be done by TSMC on an 80nm fabrication
process.
The upcoming AMD 690G is expected to feature a Radeon X700 derived graphics
core that’s been renamed ATI Radeon X1250. Features of the integrated ATI
Radeon X1250 include full support for DirectX9, shader model 2.0 support and
AVIVO. The AVIVO video engine of the Radeon X1250 supports hardware accelerated
H.264 and VC1 video processing for Blu-ray and HD DVD playback.
In addition to the standard RS690 there are four other variants
including the RS690C, RS690T, RS690M and RS690MC.The
RS690C will be the base chipset and lacks an integrated TMDS transmitter
while the RS690T is the high-end variant with support for external video
memory which is referred to as Sideport Memory. The RS690M and RS690MC
will be targeted towards AMD Turion powered notebooks.
Other notable features of the AMD 690G include support for one PCIe x16 and
four PCIe x1. The AMD 690G is expected to pair up with AMD’s SB600 south bridge
for SATA 3.0Gbps and high definition audio support. According to the article,
the AMD 690G will be pin compatible with the previous Radeon Xpress 1100 and
may possibly be able to use the same PCB.
Expect AMD 690G based motherboards to arrive in early 2007 with varied pricing
depending on which RS690 variant is employed. Chilehardware has a block diagram of the RS690 and RS690M.
