Several members were launched in the end of 2007 and the first half of 2008, others are scheduled to launch throughout the rest of 2008.

The existence of the chipsets was proven on October 2006 through two hardware websites in Chile [ [http://www.chilehardware.com/articulo.php?sid=1631&mode=thread&order=0&thold=0 ChileHardware report on "ATI chipset update"] ] [http://www.chilehardware.com/foro/amd-chipsets-roadmap-t59437.html?t=59437&highlight=Roadmap ChileHardware discussion thread] ] and Spain [ [http://www.madboxpc.com/contenido.php?id=3083 MadBoxPC reporting "ATI chipset update"] ] which posted the leaked slides of an ATI internal event, "ATI chipset update". In the slides, ATI has shown a series of RD700 series chipset logics. Codenamed "RD790", "RX790", "RS780" and "RS740" respectively. A codenamed "SB700" southbridge was also mentioned in the event. The 790X (codenamed "RD780") chipset was spotted in Computex 2007, exhibited by ASUS [ [http://www.ocworkbench.com/2007/computex/day1/p11.htm OCWorkBench Computex 2007 coverage] , retrieved January 3, 2008] , while the SB750 southbridge was reported by VR-Zone [http://vr-zone.com/?i=5157 VR-Zone report] ] . The "RS780D" was first reported by HKEPC while the "RX780H" was first seen on ECS internal presentations.

After the acquisition of ATI Technologies, AMD started to participate in the development of the chipset series. And as a result, the first performance and enthusiast segment chipsets products under the AMD brand, The 790FX, 790X and 770 chipsets were launched on November 19, 2007 as part of the "Spider" codenamed desktop performance platform. The 780 chipset series, first launched in China on January 23, 2008, and released worldwide on March 5, 2008 during CeBIT 2008 [ [http://www.digitimes.com/mobos/a20080124PD200.html DigiTimes report] , retrieved January 25, 2008] , mobile chipsets (M740G, M780G and M780T chipsets) were released on June 4, 2008 during Computex 2008 as part of the Puma mobile platform and the 790GX chipset was released on August 6, 2008, while some other members are expected to be released at a later date in 2008.

Key features

Multi-graphics

The ATI CrossFire X technology supports multiple video cards to be connected to enhance the visual display and 3D rendering capabilities of the system, using AFR mode and/or scissor mode. Alternatively, systems with multiple video card CrossFire X setup will support multiple display monitors up to eight.

For the AMD 790FX chipset, the CrossFire X [http://www.vr-zone.com/articles/ATi_Crossfire_X_Logo_%26_Performance_Scaling/5342.html VR-Zone report] , retrieved October 12, 2007] technology allows up to 4 video cards to be connected, made possible as the chipset supports four physical PCI-E x16 slots es icon [http://www.chilehardware.com/foro/daamit-rd790-t53927.html?t=53927 ChileHardware discussion thread] ] . The PCI-E lanes can be configured for 4 slots at x8 bandwidth or 2 slots at x16 bandwidth (16x-16x, 8x-8x-8x or 8x-8x-8x-8x CrossFire X setup). Reports indicate 2.6 times the performance with triple-card CrossFire than that of a single card, and more than 3.3 times the performance increase for quad-card CrossFire [http://www.vr-zone.com/articles/ATi_Crossfire_X_Logo_%26_Performance_Scaling/5342.html VR-Zone report] , retrieved October 12, 2007] . Gigabyte have revealed in a leaked product presentation that the four card CrossFire X setup does not require CrossFire connectors [ [http://forums.vr-zone.com/showthread.php?t=198123 VR-Zone report] , retrieved October 25, 2007] ; the data will be exchanged among the PCI-E slots which is monitored and controlled by Catalyst drivers.

For the performance segment, CrossFire on the AMD 790X chipset has two physical PCI-E x16 slots es icon [http://www.chilehardware.com/foro/daamit-rd790-t53927.html?t=53927 ChileHardware discussion thread] ] with one operating at x8 bandwidth (dual-card 16x-8x CrossFire), supporting up to four display monitors.

Multi-graphics is also supported for the 790GX IGP chipset, named as Hybrid CrossFire X.

AMD OverDrive

Another feature is AMD OverDrive, an application designed to boost system performance through a list of items in real-time, without a system reboot, as listed below:

* Real-time Overclocking:
** Novice mode for users not familiar with system tuning, includes a slider of level 0 to 10 for easy system tuning
** Advanced mode for more familiar enthusiasts to fine tune various system parameters including: Clock frequencies – independent clock frequencies for independent processor cores (Phenom processors only), PCI-E lanes, system bus frequency; Multipliers for each of the CPU cores and HyperTransport links (downward direction only except Black Edition processors); And voltages for CPU (VID and V_DDC), CPU HyperTransport, DDR2 Memory (V_DDQ and V_TT), northbridge core (V_Core) and Northbridge PCI-E
** "Auto Clock" for automatic fine-tuning and overclocking
* Memory fine-tuning – DDR2 Memory parameters
* System monitoring:
** System information
*** Simple mode – Windows Task Manager like CPU cores usage histogram, with CPU core clock Frequencies, CPU Multipliers, CPU core voltages (V_Core), CPU Temperature; GPU details including GPU core frequency, video memory frequency; and system parameters including system bus frequency, southbridge frequency, PCI-E lanes frequency and memory frequency
*** Detailed mode – include all system information items presented in the simple mode, with the addition of CPU caches, CPU voltages, memory details including memory frequencies and SPD settings, HyperTransport frequency and link width
** System Monitor
** (Optional) System benchmark, resulting a value to reflect relative system performance, tests include: integer computation, floating-point computation, memory speed, cache speed
** (Optional) Processor stability test, normally runs for one hour, can also be run for a minimum of 1 minute or a maximum of seven days, to identify whether the system becomes unstable for use after fine-tuning under full-loading condition. Tests include: integer (integer units) calculations and stack operations test for each processor core, floating-point (128-bit FPU) calculations test for each processor core, calculation test (Phenom processors only), MCA registers checking test
* Maintenance/User-friendly functionalities:
** Profile(s) saving and loading capabilities
** Log records output

The application will support all members of the AMD 700 chipset series, including the 740 series chipsets which are aimed at value markets, and AMD processors including Phenom and Athlon 64 family of processors, but due to architectural limitations, independent clock frequency settings for different processor cores (a feature implemented in the K10 microarchitecture) will not function on Athlon 64 family of processors (except for Athlon X2 6000 series which is based on K10).

AutoXpress

The AutoXpress technology, is a set of automatic system tuning features to enhance system performance, which were revealed by members of ChileHardware when investigating the BIOS for AMD 790FX, 790X and 770 chipsets [ [http://www.chilehardware.com/foro/novedades-chipsets-amd-t115496.html?p=1380609#post1380609 ChileHardware discussion thread] , retrieved October 4, 2007] . AutoXpress will be available on AMD 790FX (codenamed "RD790") chipset, with AMD 790X (codenamed "RD780") and AMD 770 (codenamed "RX780") chipsets implementing a subset of all the features. The AutoXpress technology is similar to the "LinkBoost" capability presented on NVIDIA nForce 500/600 chipsets.

The feature must be enabled via BIOS, options appeared in the BIOS includes ON/OFF/Custom, which choosing the "Custom" option will open up three further options, namely "CPU", "XpressRoute" and "MemBoost" with ON/OFF options, and ON as default. Details about the AutoXpress features are listed as follows:

Energy efficiency

One of the major focus of the chipset series is the energy efficiency of the chipsets. The need for energy-efficient chipsets have risen since chipsets starts including more features and more PCI Express lanes, to provide better system scalability by using PCI-E add-on cards.

But one issue is that chipset circuitries were usually made on a larger fabrication process nodes compared with the latest CPU process node, making recent chipsets to consume more and more power than their predecessors. Recent examples including the Intel X38 chipset Northbridge (MCH), labelling 26.5 W TDP with a maximum idle power of 12.3 W [PDFlink| [http://download.intel.com/design/chipsets/designex/31761201.pdf Intel Thermal and Mechanical Design Guidelines – For the Intel 82X38 Memory Controller Hub (MCH). September 2007, Revision -001] , page 14 |2.38 MiB , retrieved November 23, 2007] , which results in the world's first Integrated Heat Spreader (IHS) design over the chip to help heat spread evenly, with ASUS even adding water cooling block directly on top of the heaksink of the X38 Northbridge as a part of the motherboard heatpipe system. Although the aforementioned figures may be small compared to the TDP figures of a performance CPU, there is a growing demand for computer systems with higher performance and lower power consumption. While Intel focuses only on the energy efficiency of its processors, NVIDIA's upcoming chipset, the nForce 780i, requires an overall power consumption of 48 W with the northbridge, southbridge and the nForce 200 PCI-E bridge .

In response to this, all discrete northbridges of the chipset series were designed on a 65 nm CMOS process, manufactured by TSMC, aimed at lowering power consumptions of chipsets. According to internal testing and various reports, the Northbridge of the AMD 790FX chipset ("RD790") runs at 3 W when idle, and maximum 10 W under load [http://www.fudzilla.com/index.php?option=com_content&task=view&id=1837&Itemid=1 Fudzilla report] ] , nominal 8 W power consumption, the northbridge was seen on reference design of the AMD 790FX chipset with single passive cooling heatsink instead of connecting to heat pipes which are frequently used on current performance motherboard offers [http://www.theinquirer.net/gb/inquirer/news/2007/10/11/amd-790fx-eats-8w The Inquirer report] , retrieved October 12, 2007] , the chipset on the whole (the combination of RD790 Northbridge and SB600 Southbridge) consumes nominally less than 15 W [ [http://www.theinquirer.net/gb/inquirer/news/2007/10/17/gigabyte-debuts-socket-am2-amd The Inquirer report] , retrieved October 17, 2007]

The integrated graphics northbridges were also benefited, as most of the IGP northbridges were made on 55 nm process manufactured by TSMC with the inclusion of ATI PowerPlay technology, allowing dynamically changing the core clock frequency to minimum 150 MHz . The 780G Northbridge, sporting DirectX 10 support, consumes only 11.4 W on full load , 0.94 watt when idle [zh icon [http://www.pczilla.net/upload/200803051054362350.jpgPCZilla report] . Test results according to AMD. Retireved March 7, 2008] . This is also smaller than the TDP figures of the Intel G35 chipset Northbridge at 28 W with the maximum idle power of 11 W [PDFlink| [http://download.intel.com/design/chipsets/designex/31760901.pdf Intel Thermal and Mechanical Design Guidelines – For the Intel 82G35 Graphics and Memory Controller Hub (GMCH).

ATI Hybrid Graphics

The ATI Hybrid Graphics technology applies to all or some of the integrated graphics chipsets of this chipset series, technologies including Hybrid CrossFire X, SurroundView and PowerXpress. Reports confirmed that the 790GX IGP (codenamed "RS780D") chipset will be able to handle dual video card and IGP as a CrossFire X setup zh icon [http://hkepc.com/?id=484 HKEPC report] : AMD touts Hybrid Crossfire X technology, combining IGP and GPU, available in Q2 2008. Retrieved December 12, 2007] .

I/O acceleration technologies

All chipsets paired with either SB700, SB710 or SB750 southbridge will support two I/O acceleration technologies, as listed below:

Hybrid Drives

The southbridges also support hybrid drives via SATA or supported ATA ports, which is compliant with the requirements of the Windows ReadyDrive technology. Basically conventional hard drives with embedded NAND flash modules.

HyperFlash

The HyperFlash, basically a NAND flash module on a card, originally planned as a device connected to the supported IDE/ATA 66/100/133 channel, to speed up system performance [http://dailytech.com/AMD+Readies+Trevally+Mobile+Platform/article5989.htm DailyTech report] ] through the Windows ReadyBoost and Windows ReadyDrive functionality.

A HyperFlash module consists of two parts, the first part is a HyperFlash memory card which are flash memory chips on a small PCB (dimensions similar to a Canadian quarter 25¢, with diameter 23.88 mm, but rectangular in shape) with contacts similar to SO-DIMM modules. The other part is a flash controller on a ATA connector, with similar latches/socket ejectors as SO-DIMM sockets. The HyperFlash memory card is inserted into the flash controller and then directly plugged into the motherboard ATA connector. The memory chips used on the HyperFlash memory card will be Samsung's [http://www.samsung.com/global/business/semiconductor/products/fusionmemory/Products_OneNAND.html OneNAND flash memory modules] with maximum four-die configuration (four-die in a single package), running at 83 MHz frequency [ [http://www.samsung.com/global/business/semiconductor/products/fusionmemory/downloads/OneNAND.pdf Samsung OneNAND product identification guide] , retrieved October 25, 2007] , providing a bandwidth of 108 MB/s on a 16-bit bus width. Since the flash controller is designed to be compatible with ATA pin-out definitions (also to fit the ATA motherboard connector) and is designed by Molex, this allows OEMs to produce their own brands of HyperFlash modules while at the same time providing maximum compatibility between HyperFlash modules.

Three variants will be available for HyperFlash modules, with capacity of 512 MiB, 1 GiB and 2 GiB respectively, with expected DVT samples in November 2007, mass-production is expected in December 2007 (supported by Beta motherboard drivers) and official motherboard driver support planned in February 2008.

RAIDXpert

The RAIDXpert is a remote RAID configuration tool, for changing the RAID level of the RAID setup connected via SATA 3.0 Gbit/s ports (connected to SB600, excluding extra SATA 3.0 Gbit/s ports through additional SATA chip on some motherboard implementations), including RAID 0, RAID 1, and RAID 0+1.

Integrated graphics

Some of the members of the AMD 700 chipset series, specifically the 780 and 740 family of chipsets and the 790GX chipset, have integrated graphics onboard (IGP), as well as supporting hardware video playback acceleration at different levels. All IGP northbridges are pin-compatible to each other and even predecessors (690 series), to lower the product cost for each PCB redesign due to pin incompatibility and maximize the product lineup. These IGP features are listed below:

"Remote IT"

For the enterprise platform, the "Remote IT" technology (temporary name) was reported to be released by the end of 2007 or early 2008. The platform composed of an AMD 780V chipset with an SB700 southbridge, and chips from Broadcom, Realtek and Marvell [http://www.digitimes.com/systems/a20070720PD210.html DigiTimes report] , retrieved July 21, 2007.] . It was reported to have incorporated the Broadcom BCM5761 managed NIC controller with Intelligent Platform Management Interface (IPMI) 1.5 manageability standard [ [http://www.dailytech.com/More+AMD+RS780+Details+Revealed/article8237.htm DailyTech report] , retrieved August 1, 2007] , together with DASH 1.0 specification ( [http://www.dmtf.org/standards/mgmt/dash/ DASH page on] DMTF) support of the SB700 and SB750 southbridges, and reported support additional management and security technologies such as IDM (Intelligent Device Management) and TPM 1.2 (Trusted Platform Module).
