Based on 8th Gen Intel® Core™ Processors

DFI’s brand new board series with 8th Generation Intel® Core™ processors are ideally designed for what’s coming in the new era. We have a full form factor lineup from Mini-ITX, micro-ATX, ATX, to SOM integrated with better CPU performance support with up to 6 processor cores increasing 10% performance than previous generation even when multitasking.

Complete Product Line

DFI offers a complete product series from different form factor motherboards like ATX, microATX, Mini-ITX, and system-on-modules based on 8th Generation Intel® Core™ Processor Family with high-performance design. It is able to be perfectly fitted into different applications.

Optimized Productivity & Responsiveness

DFI’s product series are supported with Intel® Optane™ memory to accelerate computer’s responsiveness to multitask workloads without wasting too much time. Additionally, our products support with 64 GB DDR4 RAM memory up to 2666 MHz to enhance better memory bandwidth and memory transfer speeds. DFI’s motherboard comes with an M.2 (2280) to support NVMe drives with write speeds up to 3500MB/s which are 7 times over SATA SSDs.

Improved and Multiple I/O Options

Our product series with 8th gen processors adopt the newest technology USB Type-C and USB 3.1 Gen2 to benefit data transfer rates of up to 10 Gbps. It’s two times faster than USB 3.0. Furthermore, our ATX motherboard series come with Intel Q370 chipset and 24 PCIe lanes, which have 4 more PCIe lanes than the Intel Q170 chipset motherboard. This enables rich I/Os and multiple expansions, making it an ideal solution for machine vision and industrial automation application.

Fantastic Visual Performance

DFI’s completed product series with Intel 8th gen processors have the capability of delivering advanced 4K video experiences supported with resolution higher than 1080p and high quality UHD streaming media for applications such as digital signage, digital security, and surveillance.

Enhanced Security Protection

For defending equipment from external threats of security awareness, DFI’s motherboards are available with the advanced feature of iAMT 12.0 for remote management and repair of systems. Aside from iAMT 12.0, DFI’s motherboards are supported with TPM 2.0 for protecting confidential data and improving system integrations.
