AMD's next integrated graphics chipset to feature HyperFlash
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
, 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.

EIDE vs SATA where is the question...
7/31/2007 2:02:26 AM
I find it very hard to believe the following of of EIDE. Yes for a single drive it is not much different but the overall picture is much better in almost every other situation. SATA bus allows multiple drives to have the headroom to feed data at speeds EIDE could only dream of without making the entire pci buss slow to a crawl. I have 3 servers running multiple raid 5 arrays and one running 12 drives in raid 50. Out of the 22 drives I've had one drive go bad in 3 years of which the machine swapped on its own using a hot swap spare while people worked away. I replaced the spare with the machine on and nobody knew even knew there was a problem. I have also had no data errors.
Defending a very old architecture and saying it is better because you still have an EIDE drive is not an valid argument when in 95% of the other applications SATA is better. If I were a manufacturer and had to break away support from one of the two standards which one do you think it would be? Not to hard to decide. It is like all of the past standards in the computing world... they come and go. EIDE has seen its day and it is now time for it to leave into the abyss as so many others before it. Is it so hard to upgrade when a 200 gig SATA hard drive with a 5 year warranty can be bought for $70 and almost every new motherboard already has the sata port to plug it into? :-)
