Chrome has a performance lab with dozens of device and OS configurations. You can run performance tests on an unsubmitted CL on these devices using Pinpoint. The specified CL will be run against tip-of-tree with and without the CL applied.
The platforms available in the lab change over time. To see the currently supported platofrms, click the “configuration” dropdown on the dialog.
All the telemetry benchmarks are supported by the perf trybots. To get a full list, run tools/perf/run_benchmark list.
To learn more about the benchmark, you can read about the system health benchmarks, which test Chrome's performance at a high level, and the benchmark harnesses, which cover more specific areas.
Visit Pinpoint and click the perf try button in the bottom right corner of the screen.
