X299 Chipset – Key Features:

The x299 chipset by Intel promises to offer 8 GT/s DMI3 bus speed along with Lithography of 22nm. Moreover, the TDP is 6W that is quite reasonable and the motherboards are fully compatible with overclocking. Like most of the mid-end Intel motherboards, it does not feature any integrated graphics and offers 2 DIMMs per channel. It does not come with PCI support. However, offers PCIe revision for PCIe 3.0. On PCIe lanes, three configurations are available to use consisting of x1, x2, and x4. It supports total 24 PCIe lanes at a time.

There are 14 USB ports in total, using 2.0 and 3.0 version of USB. The chipset allows to use up to 10 USB 3.0 connections and up to 14 USB 3.0 connections at a time. Moreover, up to eight SATA 6.0 Gbps ports can be used, with RAID 0 / 1 / 5 / 10 support. Intel offers a lot of performance enhancing technologies. It contains Optane memory support, Virtualization technology for directed I/O, ME firmware version 11.0, HD Audio, Intel Rapid Storage, Intel Smart response, and Intel Rapid Storage for PCIe, etc. technologies. It supports most of the Intel X series processors.

X399 Chipset – Key Features:

X399 chipset by AMD is highly scalable. It makes it highly suitable for both gamers and creators, or people who do both. With serious Multi-GPU and NVMe arrays, it is the ultimate expansion beast. Additionally, quad channel Unbuffered DDR4, ECC memory support, and ultimate overclocking capacity make x399 a perfect choice for people depending on intensive computing operations. Following are some key features:

Quad Channel DDR4 memory support
Enmotus FuzeDrive Storage Technology
66 PCIe 3.0 lanes, 8 PCIe 2.0 lanes
Multi-GPU support along with AMD CrossFire and SLI technologies
Up to 2x Native USB 3.0 Gen2, 14x Native USB 3.0 Gen1 ports, 6x Native USB 2.0 ports supported
Up to 12 SATA ports with RAID 0 / 1 / 10 support
