Gen 3 (AXI) devices are measured with the PerfTest sample rather than PipeTest. PerfTest runs every bandwidth mode the device supports; this device supports modes 3 and 4.
Reading these numbers: results are grouped by bandwidth mode, and the modes trade read bandwidth against write bandwidth. Mode 3 favors reads (946 MB/s read against 315 MB/s write); mode 4 favors writes (614 MB/s write against 16.7 MB/s read). Pick the mode matching the direction your application needs. The device’s ceiling is the best figure across all of its modes, not the figure from any single one.
