rocjitsu Benchmarks

Metric Value
GEMM 823 kFLOP/s
hipFile read throughput 123 MB/s

These run inside a QEMU guest with the GPU attached over vfio-user, so the absolute numbers sit far below what the same benchmark reports on bare metal — that is expected, not a regression. What is worth watching is how they move between runs. The unit is chosen from the value, so compare the unit too.
