POSTER: computer news   ||   AMD CHIPSET 690G AND 690V	DATE:2007-02-28
Hardly someone will be able to deny, that the announcement of integrated chipset AMD 690G, previously known under the symbol ATI RS690, came out several spread. In China motherboard on the base of this chipset was already for long time sold, some important producers published the characteristics of the corresponding products. As the reasons for the delay in anoncement OF AMD 690G were different factors: problem with licensing HDCP and HDMI, problem with drivers, the scarcity of chips 690G…  It is much more important that today was finally released the chipsets AMD 690G and 690V, which in the official version got the graphic cores radeon x1250 and Radeon x1200 respectively. Differences between these chipsets is the presence of support HDCP 1.1 and HDMI 1.2 in AMD 690G and its absence in AMD 690V. This allow to save on the license deductions, witch result in lower cost for chipset AMD 690V : to $5-8 cheaper than 690G. Furthermore, chipsets AMD 690V cannot derive image to two monitors simultaneously, and also does not have the integrated sound controller of class HD audio. The graphic core in this chipsets is similar to Radeon X700 in functionality, it support DirectX 9.0 and Shader model 2.0. Amd here forget about the support Of directX 9.0c and Shader model 3.0; however, for the compatibility with interface aeroGlass from the operating system Windows vista it is sufficient to have the support Of shader model 2.0. Moreover, graphic subsystem AMD 690G considerably exceeds on speed all existing now competitors; therefore some deficiencies in functionality can be forgiven. However, even such rapid integrated chipset occurs several times slower than the discrete video card radeon x1300. This again reminds us that games are not the beneficial sphere of  those integrated chipsets. The graphic core can get 256 mb from the operational memory. Chipset AMD 690G is released by UMC company on 80 nm technical process, and this has good impact with compact sizes , low energy consumption and also it s overclocking  capability: the frequency of graphic core can without problems increase from 400 to 600 MHz. Unfortunately, there is no special performance increase with this overclock ; therefore the regular frequency of graphic core is set to (400 MHz) . The support of port HDMI for motherboard producers can be realized both the special card and it take place on the rear panel of motherboard. Chipset AMD 690V do not support DVI and HDMI, being satisfied only with D -Sub and tv-out. Chipset AMD 690G support all enumerated interfaces. North bridge AMD 690G support 24 lines PCI express, four of which are used for the connection with the south bridge SB600. Sixteen lines are reserved for the slot PCI express x16 for the connection of discrete video card, the remained four lines are for the PCI express x1 .. Since almost all motherboards on the base of chipsets series AMD 690 have compact sizes, the expansion slots are usually combined as follows: one PCI express x16, two PCI 2.3 and one PCI express x1. Focus attention, that the support of PCI express and sound controller is realized by the north bridge, and this is somewhat uncommon. Four ports SATA-300 can support regimes RAID 0, 1, 5 and 10, they are compatible with functions AHCI and NCQ. Support PATA-133 is limited to one port. South bridge SB600 support up to ten ports USB 2.0. The company albatron released on the base of chipset AMD 690G the motherboard KI690-AM2 size mini-ITX socket AM2, its sizes are only 170 X 170 mm. And with such design for albatron it was necessary to limit the number of expansion slots to only PCI. Chipset AMD 690G support the technology AVIVO and it provides hardware acceleration for h.264 and VC-1, which makes motherboard on base of such chipset suitable for the comfortable video system from disk of type HD DVD and Blu-ray. The cost of motherboard on the base of chipsets AMD 690G and AMD 690V will be in the region of $80. Later AMD will present chipset RS600, which will propose analogous functionality for the systems on the base of processors intel  core 2 Duo. The chipsets examined will allow AMD to increase their market share in the segment of integrated solutions. Related Products :
