Depends on the processor and cores.
I am guessing you have an i7
The 13inch i5 will be slower, but the higher end i7 will most probably give better results
You're comparing the multi-core results of a quad core machine against a dual core; the quad core is going to be faster for many years to come for workloads that can use all of the cores, of course ( e.g. Video encoding).
The single core scores are probably more relevant for average application use, and for these the newer processor will be conserably faster than your 2012 MBP 15.
