Those are the differences I see.
NICE research!
Assuming the ratings are accurate ... then I would say if overclocking is involved, then yes, the difference would be pretty real.
1.3ns ddr means it should be able to handle about 769mhz (effective approx 1538mhz) before it's being run out of spec
1.4ns ddr means it should be able to handle about 714mhz (effective approx 1428mhz) before it's being run out of spec.
That's almost an 8% difference in speed ...
Of course the 1.3ns ram may actually not quite run at 1.3ns, and the 1.4ns could actually be a bit faster than 1.4ns .... so my numbers are just theorycraft, and not actual real usable information ... so they should be taken with a grain of salt.
