> Unfortunately, the laws of physics driving DRAM cells have not improved much over the last couple of years (or decades, for that matter), so memory chips still must operate with similar absolute latencies, driving up the relative CAS latency. In this case 14ns remains the gold standard, with CAS latencies at the new speeds being set to hold absolute latencies around that mark. Some gaming memory kits can do 10ns or…

> Some gaming memory kits can do 10ns or less latency

Without a thorough analysis by real engineers my interpretation of this statement is "DRAM marketers can print anything they want on the sticker".
