Intel owns the super high-end/enthusiast PC market with its flagship Core i7-6950X processor, but it looks like AMD could have its sights set on that market as well - with the first images of a purported X390 and X399 chipset. The new rumors are coming from Reddit, with someone posting some diagrams of the alleged X390/X399 chipsets.
Starting with the X390 motherboard, which is an ASUS made board - it features a much larger 'AM44' socket - which could be a typo, but maybe 4+4 = 8 and we're looking at the AM8 socket? On top of that, the purported ASUS-made X390 motherboard features their awesome Aura Sync technology, for RGB LED goodness - and 8 x DIMM sockets for a massive amount of RAM. We have 44 PCIe 3.0 lanes on the X390, compared to just 40 lanes on Intel's HEDT chipset in X99.
Moving onto the X399 chipset where things get really interesting, as the X399 chipset is destined for dual-CPUs - like the upcoming Naples CPU which is a workstation/server processor, with ECC support. AMD's purported X399 chipset would take 44 PCIe 3.0 lanes per CPU, for 88 PCIe 3.0 lanes in total. Madness.
From these rumors, it looks like the X390 chipset would take in the purported Ryzen CPU with 16C/32T that AMD will reportedly launch later this year to tackle Intel's flagship Core i7-6950X. The X399 on the other hand, if it were to reach the consumer market, could offer much cheaper dual-CPU systems to people compared to Intel's Xeon platform.
