How can I obtain/calculate the memory latency of my GPU without measurement?
<p>The <code>cudaGetDeviceProperties()</code> API call does not seem to tell us much about the global memory's latency (not even a typical value, or a min/max pair etc).</p>

<p><strong>Edit:</strong> When I say latency, I actually mean the different latencies for the various cases of having to read data from main device memory. So, if we take <a href="http://arxiv.org/pdf/1509.02308.pdf" rel="nofollow">this paper</a>, it's actually 6 figures:  { TLB L1 hit, TLB L2 hit, TLB miss } x L1 data cache turned { on, off }.</p>

<p><strong>Q1: Is there a way to obtain these figures, other than to measure them myself?</strong><br>Even a rule-of-thumb calculation based on SM version, SM clock and mem clock might do.</p>

<p>I would ask the secondary question, being:<br>
<strong>Q2: If not, is there a utility which does this for you?</strong> <br>
