rMBP CPU Confusion

yeap, theres this slight processor bump in february 2013.

the 'latest version' is indeed a bit misleading.

you can assure him that the processor bump is insignificant.

 

it's essentially the same computer except for the CPU. The CPU is still the same type from Intel (Ivy Bridge), it's just that in around Feb 2013, Intel dropped their prices a little and Apple responded by keeping the price the same, but buying a little fancier processors from them. A .1 ghz improvement is marginal at best and shows very little real world difference.

In my opinion, the Ivy Bridge version that is out now is still first generation, and the inevitable Haswell version will be the second generation.

 

Ya you made (an honest, so it seems) mistake. At this point either apologize and risk the buyer wanting to return the sale, or equivocate! Say you meant by latest model the design of the machine, which hasn't changed at all, or say you meant latest model meaning Retina screen with no CD/DVD drive and with IveBridge CPUs.

Depends on the specific units. Many of them have LG screens, and the newer versions, I won't say models, have a different panel that supposedly addresses some of the manufacturing problems the first versions (2012s) had. If you had a Samsung panel its probably only the CPU which had a change to it. But if you had the LG panel, there is a good chance there are small minor tweaks when comparing it to the 2013s. But as far as the specs Apple publishes, the only difference is the .1 ghz on the CPUs, which is trivial.
