Manufacturer's description and specifications:

The ExaNIC X25 is the fastest ExaNIC ever built. It is up to 20% faster than previous ExaNIC models.

Users will find this drop-in replacement NIC accelerates low latency application performance to previously unachievable levels. It offers software trigger-to-response latencies as low as 568ns for small Ethernet frames.

The device features an advanced free and open source software interface optimized for low latency network processing. Features include: zero latency programmable receive steering, cut-through packet streaming, pre-loaded packet transmission, and TCP/IP acceleration.

The ExaNIC X25 is built using the latest generation of Xilinx Ultrascale+ FPGA. Users can make use of the FPGA by offloading critical network processing functions directly into the NIC, while maintaining the ease of use and administration of a production grade network adapter. It optionally ships with 4GB of DDR4 memory for custom use.
