Is there a big difference in performance between AMD A4 and A8?

[ihatebsods]

So I am looking to buy one of these laptops:
1.(cheaper one) http/h10025.www1.hp.com/ewfrf/wc/document?docname=c04125225&cc=sr&dlc=en&lc=en
2.(a little bit more expensive) http/shop.lenovo.com/gb/en/laptops/lenovo/g-series/g505s/#tab-tech_specs

Is there a big difference in performance?
I will use it mostly for playing League of Legends and maybe Tera Rising,DotA 2 etc.

Actually I think it is 4500m.
At least on the website of the store I am going to buy it from is saying "AMD Quad-Core A8-4500M 1.9GHz (4MB L2 cache, 35W, 32nm)"

Yeah sorry about that.
So I guess it is better to buy the A8-4500 one.
Thanks for the help
