關於AMD晶片的疑問？
 

各位大大，想要請教一下關於AMD南北橋晶片的問題。
目前AMD的790GX、790FX、790X、785G、770、760G、740G
這幾款到底有什麼差別？
1.內建顯示？
2.速度？
3.其他？
南橋也有不少款，真的很難弄清楚 :confused: ，請各位大大幫忙解惑一下，感恩啊！
PS.聽說三月要推出890系列以及SB850的晶片，產品布線上會跟7系列的一樣嗎？
想要換電腦，還在霧煞煞中啊。

AMD Northbridge Options


AMD’s 700-series chipsets provide a multitude of options for both discrete (no onboard graphics) and integrated graphics customers. Northbridge products include:


•790FX, with 42 PCIe 2.0 links, the best match for multiple graphics cards.
•790X, a lower-cost 26-lane version of the 790FX that supports a single graphics card with 16 lanes or two cards with eight lanes per card.
•790GX, an integrated-graphics version of the 790X that supports discrete graphics, integrated DirectX 10.0 graphics, and combinations of AMD discrete cards with integrated graphics.
•785G, an updated version of the 780G that supports DirectX 10.1 and HDMI 1.3.
•780G, a lower-cost version of the 790GX that supports a single AMD graphics card and integrated graphics simultaneously for enhanced multi-monitor support.
•780V, a lower-cost version of the 780G that supports fewer graphics features.
•770, a version of the 780G that has no integrated graphics and supports a single graphics card in true x16 mode. An additional graphics card can be hosted at reduced bandwidth by using four of the chipset’s x1 pathways.
•760G, a version of the 780G with a reduced-performance graphics engine that supports integrated and discrete graphics, but not simultaneously.
•Older models such as the 740G that do not support the higher-speed HyperTransport connection of AM2+ and AM3 processors.


AMD Southbridge Options


AMD’s introduced SB700-series southbridges after several motherboard models had already been released using a combination of newer and older parts. Modern designs use the SB700 series exclusively.


•SB750 adds the RAID 5 user option to the SB710’s feature set, and is reputed to offer better SATA and USB performance than previous models.
•SB710 adds Advanced Clock Calibration (ACC) and integrated control of legacy I/O ports to the SB700’s features. ACC is used by overclockers to improve the scalability of some processors (first-generation Phenoms), and/or to enable cores that were disabled during the manufacturing process.
•SB700 supports up to six SATA drives at 3.0 Gb/s in legacy mode, AHCI mode, and RAID modes 0, 1, and 10. Two Ultra ATA drives are also supported at up to 133 MB/s, along with 12 USB 2.0 devices
