The motherboard which is designed by an unknown manufacturer comes with a very early design but seems to be rocking the LGA 1700 socket which will support intel's Alder Lake CPUs.
The pictures show what seems to be an Intel Z690 chipset-powered motherboard but in an early design variation which is made apparent from the lack of heatsinks and a proper mounting socket on the LGA 1700 pad.
The Alder Lake desktop CPUs will come in a 37.5x45.0mm package and will be supported by the 'V0' socket which we know as LGA 1700.
Rumors are that Intel might hurry its Z690 motherboard and miss out on Gen 5 for Alder Lake CPUs but that remains to be confirmed.
