 AMD’s latest roadmap reveals more details of its upcoming next-generation RS780 chipset.
AMD plans to target the chipset towards consumer and commercial desktop
platforms, with minor differences for each respective segment. AMD
designed the RS780 to accommodate its upcoming Socket AM2+ processors
with HyperTransport 3.0.
The RS780 sports a new graphics core with AMD’s Universal Video Decoder, or UVD, technology for hardware acceleration of H.264 and VC-1 video formats. The new chipset supports DisplayPort,
DVI and HDMI digital video output interfaces. AMD also integrates an
audio controller for simultaneous audio and video output over HDMI. The
chipset also integrates HDCP support.
Additionally, the
chipset supports TV-out, VGA and LVDS outputs. The graphics core also
has two independent display controllers for dual independent displays.
The local frame buffer feature will make a return on the RS780,
allowing manufacturers to equip the graphics core with dedicated video
memory. Users that prefer more 3D graphics power can install an
external graphics card via a PCIe 2.0 x16 slot. The RS780 will also
have additional PCIe 2.0 lanes for lesser slots.
New to the RS780 platform is the
SB700 south bridge. The SB700 does away with all PCIe lanes and only
supports PCI, because all PCIe functionality has moved to the north
bridge. AMD increases USB support to 12 USB 2.0 ports plus an
additional 2 USB 1.1 ports. The new south bridge supports up to six
SATA 3.0 Gbps ports with RAID 0, 1 and 10 support. IDE remains a
supported feature of the SB700. However, AMD designates the IDE port
for double duty – a physical PATA port or for HyperFlash. HyperFlash is
AMD’s name for its Intel Turbo Memory competitor.
RS780 for
commercial platform has one minor difference compared to the consumer
platform. AMD designates a Broadcom BCM5761 managed NIC controller for
the commercial platforms. The managed NIC allows for remote management,
similar to Intel’s AMT technology. AMD also recommends a TPM 1.2 module
for greater security.
Expect AMD to unveil the RS780 sometime next year.
