The following tables list the performance of x1, and x4 operations with the Intel® Cyclone® 10 GX FPGA development board for the Intel® Xeon® E5-2603 Sandy Bridge EP processor using this reference design. The table shows the average throughput with the following parameters:
  • 100 KByte transfer
  • 20 iterations
  • A 256-byte payload
  • Maximum 512-byte read request
  • 256-byte read completion
Note: Refer to the following web page for other available reference designs and application notes for PCI Express.
