A low latency, high performance coherent interface is achieved when connecting the FPGA to selected Intel® Xeon® Scalable Processors via Intel® Ultra Path Interconnect (UPI), while the non-coherent interface takes advantage of any PCI Express* (PCIe) Gen4 capable device.

The FPGA's external memory capability now includes support for a new DDR-T soft IP memory controller, allowing interfaces to attach up to 1 TB of high-performance, persistent Intel® Optane™ PMem modules per controller, directly to the FPGAs GPIO banks.

In addition to supporting these interface protocols, the DX variant FPGAs also offer hard intellectual property blocks for 100 Gigabit Ethernet and DDR4 memory control, combined with a high-performance monolithic 14 nm FPGA fabric die, all inside a single flip-chip FBGA package. Select Intel® Stratix® 10 DX devices include an integrated quad-core 64-bit Arm* Cortex* -A53 hard processor subsystem (HPS) on the fabric die, or embedded 3D stacked High-Bandwidth (up to 512 GB/s) DRAM memory (HBM2) inside the package.

As part of the Intel® Stratix® 10 family, the DX variant devices feature other innovations such as the Intel® Hyperflex™ core architecture, variable precision DSP blocks with hardened support for both floating-point and fixed-point operation, and advanced packaging technology based on Intel® Embedded Multi-die Interconnect Bridge (EMIB).
