Intel’s 600-series line-up has leaked, including X699 chipset | KitGuru
 
The leak comes from HXL, which found the whole 600-series line-up on the Intel Chipset driver 10.1.18836.8283. According to what HXL found, the 600-series includes the following chipsets: X699, W685, W680, Q670, Q670E, Z690, H670, B660, H610, H610E and R680E.
 
Until now, we have not heard much about the X699, but considering Intel’s naming history, it should be used on a new HEDT platform. Besides HEDT chipsets, the line-up will also include the workstation-oriented W685 and W680, and the business-grade Q670 and Q670E (laptop). The mainstream segment features the flagship Z690 chipset, followed by the mid-range H670 and B660, and the entry-level H610 and H610E (also laptop). Lastly, there’s the R680E chipset, which should be used on embedded (R) laptops (E). Featuring the LGA 1700 socket, Intel 600-series motherboards will support DDR5-4800 memory and PCIe 5.0. The release date hasn’t been announced yet, but they should launch around the same time as the Intel Alder Lake CPUs, coming out later this year.
 
Nothing here that doesn't surprise me. I am curious if Intel releases next gen CPUs this quarter or the last fiscal quarter of the year.

What does the EVGA x699 motherboard look like and when can I pre-order?

As far as the x699, nobody knows what it will look like nor has there been any rumors as to when it might be announced.  The above leak was four weeks ago.
 
The Alder Lake GPU is "alleged" to be announced on 19 Nov and it is the LGA1700 chip.  MB manufacturers have not announced Z690 yet and there are only leaks.
 
As far as the x699 MBs and the next HEDT GPU, it will be sometime next year before we hear anything.
 
Treat all "Leaks" and "Rumors" with skepticism as there may or may not be a small grain of truth in them that is surrounded by guessing.
