Recommended FPGA Fabric Speed Grades

Gen4 x16 512-bit 500 MHz / 400 MHz / 350 MHz -1,-2
x8 256-bit 500 MHz / 400 MHz / 350 MHz -1,-2
x4 128-bit 500 MHz / 400 MHz / 350 MHz -1,-2
Gen3 x16 512-bit 250 MHz -1,-2
x8 256-bit 250 MHz -1,-2
x4 128-bit 250 MHz -1,-2
Note: Speed Grade -3 may be supported in a future release.

The following table shows the typical resource utilization information for selected configurations.

The resource usage is based on the Avalon® -ST IP core top-level entity (intel_pcie_ftile_ast) that includes IP core soft logic implemented in the FPGA fabric.
