Encyclopedia
The AMD 700 chipset series (also called as AMD 7-Series Chipsets) is a set of chipsets designed by ATI
ATI Technologies
ATI Technologies Inc. was a semiconductor technology corporation based in Markham, Ontario, Canada, that specialized in the development of graphics processing units and chipsets. Founded in 1985 as Array Technologies Inc., the company was listed publicly in 1993 and was acquired by Advanced Micro...

Phenom is the 64-bit AMD desktop processor line based on the K10 microarchitecture, in what AMD calls family 10h processors, sometimes incorrectly called "K10h". Triple-core versions belong to the Phenom 8000 series and quad cores to the AMD Phenom X4 9000 series...

 processors to be sold under the AMD brand. Several members were launched in the end of 2007 and the first half of 2008, others launched throughout the rest of 2008.

Development history

The existence of the chipsets was proven in October 2006 through two hardware websites in Chile and Spain 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 SB700 southbridge

 was also mentioned in the event. The 790X (codename RD780) chipset was spotted in Computex 2007, exhibited by ASUS, while the SB750 southbridge was reported by VR-Zone. 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.

Advanced Clock Calibration

Advanced clock calibration (ACC) is a feature originally available for Phenom families of processors, particularly for Black Edition ones, to increase the overclocking potential of the CPU. ACC is supported by the SB710 and the SB750 southbridges, and available through BIOS settings on some motherboards and AMD OverDrive utility.

It was later discovered that this functionality has the possibility of unlocking the supposedly disabled cores of some Phenom II X2/X3 processors. In normal cases, it is not possible to use or unlock any of those hidden cores because originally those cores were disabled: a technique called "chip harvesting" or "feature binning" used by AMD to sell parts with one or two defective cores which will cause system instability if not disabled.

The following are available through the Advanced Clock Calibration feature:
  1. Auto or manual settings
  2. Allow separate settings for each of the CPU cores
  3. Allowed range: -12% to +12%
  4. Possibility of unlocking AMD Phenom II X2/X3, AMD Athlon II X2/X3 and AMD Sempron locked cores / cache. (with BIOS support)


The principle of ACC is not publicly discussed by AMD but some third-party vendors, including ASUS (Core Unlocker) and Biostar (BIO-unlocKING) have had it for some time. Gigabyte has added this feature, called CPU Core Control, to many NB785/SB710 boards via BIOS update, and will be including this feature (now called Auto Unlock) in all of their 800 Series boards with the SB850 chip. On many of the boards, the feature is dependent on BIOS version. While NVIDIA also has a similar technology for its nForce 780a motherboards, called NVCC (NVIDIA Clock Calibration) with very similar functionality.

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

 even adding water cooling block directly on top of the heatsink 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 nForce 780i chipset 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

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.

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. Hybrid Graphics are only available with 24xx, 34xx, & 42xx model ATI graphics cards.

However, it was reportedly cancelled.

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.

 considered the 780G "a better balanced chipset offering improved casual gaming performance, equal video quality, similiar [sic] power requirements, greater availability, and better pricing." The 8200, however, was preferred as a single-purpose HTPC solution. Both chipsets were considered superior to Intel's G45/X4500HD, which was cited for a lack of driver quality and features, and a higher price.
