Intel Stratix 10 FPGA Nallatech 520N FPGA Network Acceleration Card

Scalable compute node with optical I/O for creation of directly-coupled, dense FPGA clusters

Introducing ground-breaking single precision floating point performance of up to 10 TFLOPS, the OpenCL-programmable 520N features an Intel Stratix 10 FPGA, along with four banks of DDR4 external memory.

Four network ports enable dramatic FPGA-to-FPGA scaling independent of the PCIe bus, plus support for an array of serial I/O protocols operating up at 100/40/25/10G.
