System Speed-of-Light
|

*********************
|
||
|
||
The page lists the System Speed-of-Light metrics from various sections
|
||
of the ROCm Compute Profiler’s profiling report for AMD Instinct™ MI-Series
|
||
GPUs based on CDNA-CDNA4 architectures.
|
||
|
||
For RDNA3.5 (gfx115x) APUs, see :doc:`../rdna/system-speed-of-light` under RDNA3.
|
||
|
||
.. warning::
|
||
|
||
The theoretical maximum throughput for some metrics in this section are
|
||
currently computed with the maximum achievable clock frequency, as reported
|
||
by ``rocminfo``, for a GPU. This may not be realistic for
|
||
all workloads.
|
||
|
||
Also, not all metrics (such as FLOP counters) are available on all AMD
|
||
Instinct MI-Series GPUs. For more detail on how operations are
|
||
counted, see the :ref:`metrics-flop-count` section.
