Per reader requests, several software-defined radio (SDR) benchmarks have been added alongside the 640+ other distinct workloads available for benchmarking via the Phoronix Test Suite and

For those interested in evaluating CPUs for software-defined radio or signal processing purposes, some of the latest test additions may be of interest to you. GNU Radio, LuaRadio, srsLTE, and Liquid DSP are now all available for benchmarking via the Phoronix Test Suite /

Via those OB links are already a number of reference CPU results available for those curious about the latest processors in those radio benchmarks. Those tests will also be included in some upcoming CPU reviews. There is also now an SDR test suite so running these new tests is as easy as phoronix-test-suite benchmark sdr.

This week were also a number of other new and updated benchmarks for PTS/OB users.

There are currently 642 distinct benchmarks that can be run via the Phoronix Test Suite that in total have seen 2,173 revisions so far as well as 139 different test suites for better classifying and correlating those test profiles into different logical groups. Running every single test profile and option from the Phoronix Test Suite on average carries a run-time of some 34 days and 19 hours but thankfully most only run the small sub-set of tests relevant to their individual workloads/interests.

Even more tests continue to be added as well, so stop by to see the latest.
