SRIO performance

chen xie

Dear TI,

Can you show me that the max speed of the SRIO 4x @5Gbps? Is it really reach 20Gbps？

I can only achieve nearly 11Gbps at SRIO 4x @5Gbps in the our design. The swtich is used IDT CPS1848 and I think it is not the limited problem. Is the software I used wrong?

Thank you in advanced!

Hi Alan,

Please refer below Section 15 of Throughput Performance Guide for KeyStone Devices for SRIO performance values.

Hi Alan,

Were you able to take a look at the Throughput Performance Guide that Rajasekaran mentioned in the post above? It looks like the throughput you are measuring is similar to what was achieved in the testing for the guide in the 4x 5Gbps configuration when sending the largest payload size with message passing.

Let us know if you have any further questions.

Thanks,

Clinton
