nForce 590 is the name of the high-end models in NVIDIA’s new chipset series, nForce 500. We’ve already seen information about MSI’s nForce 500-based motherbords and then it was relatively little separating these Socket AM2 motherboards from today’s Socket 939 boards based on the nForce 4 chipset. It seems NVIDIA has a few trumps up its sleeve though and this is mainly more or less just a tuned PCI Express bus. It’s the nForce 590 models that sports NVIDIA’s Trinity technology that together with video cards that also sport the technology will result in considerably better PCIe bandwidth. When a Trinity capable moderboard and a Trinity capable video card is put together the bandwidth will increase from 4GB/s to 5.2GB/s, I.e. moving from PCIe x16 to PCIe x20/x22.
Exactly how this is done is a bit unclear, but it seems to be an overclocking of the PCIe bus and thus results in a considerably higher bandwidth, whether this actually results in any better performance is also uncertain. Also how the technology works with different technologies video cards, especially with other manufacturers models.
