ATI has announced its latest core logic
chipsets for AMD's
AM2 platform. Two new chipsets are being announced for AM2: the
Radeon Xpress 1100 and the Radeon Xpress 1150. Also new is the SB600
series southbridge which offers support for ten USB 2.0 ports, four
SATA-II ports, RAID, HD Audio and legacy support for PATA devices.
Native Command Queuing (NCQ) is also present on the southbridge. The
SB600 southbridge supports both AMD and Intel platforms.
The Radeon Xpress 1100/1150 IGPs
feature a Radeon X300 graphics core clocked at 300Mhz (Xpress 1100)
and 400MHz (Xpress 1150). Up to 128MB of memory can be allocated to
the GPU thanks to ATI's HyperMemory technology. The GPU is fully
DirectX9 compliant and features support for Vertex Shader 2.0 and
Pixel Shader 2.0 so support for Vista Aero Glass is assured. Other
niceties include SurroundView technology which allows for up to three
monitors to be used with an accompanying ATI graphics card, dual
independent displays (CRT/LCD, TV/LCD), DVI support and an integrated
TV encoder. The Radeon Xpress 1100 series features one PCIe x16 link
and four general purpose PCIe x1 links.
ATI's CrossFire Xpress 3200 chipsets carryover for Socket AM2 platform. We should expect to see motherboards
featuring Radeon Xpress 1100/SB600 within the next month.
