AMD Chipset 2008

AMD 700 Chipset

The AMD 700 chipset series (also called as AMD 7-Series Chipsets) is a set of upcoming chipsets designed by ATI to be sold under the AMD brand and is scheduled to launch between the end of 2007 to the first half of 2008.

The existence of the chipsets was proved on 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 have shown a series of RD700 series chipset logics. Codenamed RD790, RX790, RS790 and RS740 respectively. A codenamed SB700 southbridge was also mentioned in the event. The 790X (codenamed RD780) chipset was spotted on Computex 2007, exhibited by ASUS, while the SB750 southbridge was reported by VR-Zone .

Availability

The 790FX, 790X and 770 chipsets were launched on November 19, 2007 as part of the Spider desktop performance platform, While the others will be released on the first half of 2008, including M740G, M780G and M780T chipsets.

Lineup

790FX

• Codenamed RD790, final name revealed to be "AMD 790FX chipset"
• Dual-socket (Quad FX, Dual Socket Direct Connect (DSDC) Architecture) or single AMD processor configuration
• Maximum four physical PCI-E x16 slots and discrete PCI-E x4 slot , the chipset provides a total of 42 lanes solely in the Northbridge
• HyperTransport 3.0 with support for HTX slots and PCI Express 2.0
• ATI CrossFire X
• AutoXpress
• Extreme overclocking, reported to have achieved about 420 MHz bus for overclocking an Athlon 64 FX-62 processor , from originally 200 MHz.
• Discrete chipset cache memory of at least 16 KB to reduce the latencies and increase the bandwidth
• Supports Dual Gigabit Ethernet, and teaming option
• Reference board codenamed "Wahoo" for dual-processor system reference design board with three physical PCI-E x16 slots, and "HammerHead" for single-socket system reference design board with four physical PCI-E x16 slots, also notable was the reference boards includes two ATA ports and only four SATA 3.0 Gbit/s ports (as being paired with SB600 southbridge), but the final product with SB700 or SB750 southbridge should support up to six SATA ports
