Which one to choose: ThinkPad W530 CPUs

Hello all, I am looking to buy a ThinkPad W530 from eBay.  I found two options for CPU from all the online listings, Intel i7-3520M or i7-3740QM. 

 

I am not asking about the differences about the two CPUs, which I can find online.  My questions are: Can we tell which edition is newer/later?  Or, does the difference result from customizations?

 

I would like to choose the newer model, in the hope that it is also the better or improved version.

 

Any insider's info will be appreciated.

They are both 4 - 5 years old.  The i7-3520m is 2 core and the i7-3740QM is 4-core.  The 3520 has a faster clock speed and will run faster single-threads.  The 3740 will run more threads at once.  The dual-core can address 16GB of memory (2X8gb) The quad core cpu will address 4X8gb

Re: Which one to choose: ThinkPad W530 CPUs

Thank you very much, richk, for the info! It is pretty helpful.

 

I later found they are also models with i7-3720QM, which I assume is very close to 3740QM.  I guess I would prefer 3740 then, since it is better for multi-tasking. 

And we're back...
