Associate with reference to motherboards producers reported yesterday that NVIDIA was able obtain the QPI license, This license apply to chipset production ( LGA 1160) averages and initial price levels.
Technically, these motherboards do not use QPI, but the corresponding license is necessary TO NVIDIA even in this case. We note, that Intel x58 chipset is capable to support CrossFire X without any additional chip like nForce 200 for SLI support . However, the presence of this chip will allow the support Of both crossFire X and SLI.
In case of four core processors Lynnfield LGA 1160 the PCI express controllers is arranged inside the processor, but the support of two slots video card with : PCI express x8 + PCI express x8 can be realized, also, on these motherboards. The dual core processors havendale LGA 1160 will obtain the integrated graphic core, and with the discrete video card they will communicate through the PCI express x16 interface.
Associate note, that X58 motherboards will be expensive not only due to the high chipset cost ($70) and the nForce 200 chip ($30), but also because due to the need of six or eight-layer design printed-circuit board.
LGA 1366 Processors work with the three-channel memory; therefore the majority of motherboards will be equipped with six slots DIMM, and this requires a more qualitative separation and an increase in the number of slots. Each two additional Textolite layers increase the prime cost by 50%.
