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.

RAID 0, 1 and 10 support
I would like to have seen Raid 5 and 6 as an option because Raid 10 looses too much disk space.
In all I will probably raid-0 and do daily backups of important data to another drive anyway. I can always reload my software and games.

It could be worse. Intel has removed ALL Ide support in ICH9 and ICH8, with the result that every motherboard manufacturer now has to add an extra controller for such a basic function. Even if you're willing to put up with the F6 nonsense when installing you might well find yourself up a creek if your hd dies and your image backup program doesn't have support for the third-party IDE controller (do a search for Acronis SATA problem)!
This is called "progress" by the wise idiots at Intel and now AMD too, as well as the 16-year olds who think SATA is soooo much faster because it has a theoretical 300Mb/s transfer rate.
The same 188t idiot 16-year olds who don't back up their hard drives, so why would they mind if an "it just works" solution has been replaced with something that either needs drivers (AHCI) or which works in PATA emulation mode with the new features (NCQ, 300MB/s) disabled.
I'm just waiting for a bleeding-edge bozo to tell me that Vista works fine (5% installed base)!

Yea Im not ready to abandon EIDE.
Im not thoroughly impressed with SATA/SATA2 as I have had a few msft$ errors with them while my EIDE drives dont seem to have those issues. Not sure what causes it but I get one every couple of months and only on my SATA drives and thats a disaster for RAID. I do the usual reboot and disk diagnostics to find nothing. This is on 3 different machines from ASUS, HP, and The third might be an EPOX. And with 3 different SATA drives from seagate, maxtor, and western digital. Wouldnt be fun to rebuild an array every 3-4 months I see one of those errors.
As for air cooling being superior on SATA well the air in my case moves across the drives one side to other side it doesnt try moving the air from the front of the drive to where the cable resides which is bad design or the typical cheap case.
I like Vista but I dont like its performance or its compatibility with a few of my critical apps.
