Maximum bandwidth intel Arria 10gx, Strattix 10 sx

Hello everyone,

What is the maximum bandwidth that intel Arria 10 gx and intel Strattix 10 sx can arrive to write and load from global memory?

I have searched many places for the answer to this question but could not find it.

From the report in View->System Viewer I can see that the throughput for Arria is 960 Mb/s and for Strattix is 1400 Mb/s. Are these the maximum bandwidth for these devices?

Thank you in advance.

    Hi Giulio,


    May I know where View --> System Viewer are you referring to? Is it in Quartus?

    On my system viewer in the FPGA report, for Stratix, the memory controller lists 13824 MB/s for both read and write, separately. This is about in line with the ballpark figure I have been given of "12 GB/s in one direction", which roughly matches the PCIE 3.0 x16 theoretical of 15.754 GB/s (which doesn't account for transfer overheads).
