Stratix 10 FPGA Board with 16GB HBM2
Powerful solution for accelerating memory-bound applications
Designed for compute acceleration, the 520N-MX is a PCIe board featuring Intel’s Stratix 10 MX2100 FPGA with integrated HBM2 memory. The size and speed of HBM2 (16GB at up to 512GB/s) enables acceleration of memory-bound applications. The board’s 100G QSFP28s are ideal for clustering, and OCuLink connectors allow expansion.
Both traditional HDL and higher abstraction C, C++ and OpenCL-based tool flows are supported. Deliverables include an optimized board support package (BSP) for the Intel OpenCL SDK. The 520N-MX features a Board Management Controller (BMC) for advanced system monitoring and control, which greatly simplifies platform integration and management.
