Intel RD600 & nForce 590 in October

October will finally be the release date of the new ATI and NVIDIA chipsets for Intel platform and to be more specific for Core 2 Duo: RD600 and nForce 590 SLI. NVIDIA will apparently be the first to release a chip as ASUSTeK expects the first shipments at the beginning of the month.
Announced during the Computex, the nForce 590 SLI includes 48 PCI Express lines, 6 SATA ports, 2 Gigabit networks ports and support 1066FSB and DDR2-667. Initially scheduled at the end of July, it has been so much delayed that for now we have to use an nForce 4 SLI Intel Edition to have two cards in SLI with a Core 2 Duo.
In practice, there are not many differences as the Northbridge are the same! The two also have the same unpleasant tendency to have a low FSB overclocking capacity compared to Intel's chipsets.
The RD600 initially scheduled at the beginning of the year and postponed several times will probably be better for Overclocking. ATI said that it will support FSB1333 and that it could reach 375 MHz (FSB1500) in overclocking (this was said three month ago). Even more interesting, it would be possible to adjust asynchronously the FSB and memory speed. Beside these points, it will of course be possible to have two 16X cabled PCI-E port. The SB600 has, however, modest characteristics (no Gigabit Ethernet for example, 4 SATA ports).
Now, the thing is that these chipsets won't last long. NVIDIA already seems to focus on the successor of the nForce 590 SLI, which will use a new Northbridge the C55 (scheduled before the end of the year) and ATI will simply stop the production of chipsets for Intel platforms after the RD600. This is the reason why some of the motherboards manufacturers are rather cautious about the release of a mobo S775 based on ATI chipset.
