You can hit up CPUBOSS to compare just the CPUs. But better yet is to see if this model or one of it's near enough models is on Notebookcheck or CNET.
If there were no other details I might go with number one.

Hello! I'm comparing a couple of laptops. Can you give some advice on which specs are better?

8GB DDR3L SDRAM
#2:
2.4GHz Intel Core i3-3110M dual-core processor
6GB DDR3 SDRAM
Thanks
