Any benchmarks are just that, it tells you what something does in a given circumstance, a normal person - except when gaming - has a number of things going on, browsers (often multiple tabs/windows) and other apps open and running, this is where higher freq and tight CLs come into play - it's processing more and faster to help eliminate reads/writes to your page file on the hard drive, also with memory centric apps like imaging, video, CAD, VMs, the performance DRAM excels....when looking at reviews the writers almost always throw in the line that you won't see any real difference in 'real world' scenarios --- BUT --- they never show anything to show real world scenarios, because there is no BM to show it....this same 'real world' line most all use has been being said for years going back to DDR and DDR2 (even SIMMs)...also note than many of these 'reviewers' don't know DRAM, can't remember how many 'reviews' I've seen where they (these experts) make ridiculous remarks like "the DRAM is 1866 but only started at 1333"....duh, all DRAM when first installed goes to the mobo default......or 'the set of DRAM failed to set the correct XMP settings when XMP is enabled" again ...duh...the DRAM has XMP profiles in the SPD which are, pure and simple - information - nothing more nothing less, when XMP is enabled it's up to the BIOS to take that info and properly implement it, which often the BIOS doesn't do - and is why you see so many BIOS updated, while seldom shown, more often than not the buld of BIOS updates consists of DRAM XMP updates.
