Lets breakdown the different elements in the modules description:
 
'''PC3L Vs PC3'''
 
'''PC3''' is standard voltage (1.50V) where '''PC3L''' is low voltage (1.35V) - A system which requires PC3L cannot support PC3 RAM. PC3L RAM will work in a PC3 based system as it will run at the standard voltage and will inter-operate with PC3 RAM within the system.
 
'''12800 MB/s (DDR3-1600) Vs 10600 MB/s (DDR3-1333)'''
 
The Letter S just means its a SO-DIMM Vs a standard DIMM
 
This is the speed of the RAM Clearly DDR3-1600 is able to run faster than DDR-1333. But thats only the modules ability not what the system is running its memory bus speed at. Your MacBook was designed for PC3-10600 DDR3 SDRAM, its best to stick with what Apple expects. You can use the faster RAM, but, you really won’t see a sizable difference. So don’t spend extra for the few nano seconds of improvement. Instead

Consider going with more than 8 GB of RAM I would go with 16 GB if you want better performance working on large items or running multiple apps concurrently.

Instead
focus on your drive If you haven’t already done it consider going to a SSHD hybrid drive or better yet a good high speed SSD. Both of these will offer more improvement.
