I was just talking with someone about this yesterday. Q6660, do you even imagine that bf4 will be more optimized and run badly on an i5? Bf3 didnt even use the 4 cores of the i5 FULLY, so how would bf4 manage to fully use it and overcome this barrier to be more optimized on the multi-threaded AMD cpus. I know the thread is for bf4 specially, but most of the games favors intel and their single core performance. Here are some cpu intensive games that uses mroe than 4 cores and their performance on i5 and fx 8350 BF3 on 64 servers :http://forums.anandtech.com/showthread.php?t=2307366 and arma 3
http://www.techspot.com/review/712-arma-3-benchmarks/page5.html , if you would notice the i5 performs better in both. By the way, i am not experienced with such matter as im not a programmer, but every single person who understands in programming says that devs cant write a game code that utilizes the 8 cores of the ps4 ONCE its released, this is demanding process that would take some time like (1-2 years), so i think till then, the i5 will still be superior to AMD cpus and after that period, they might become equal in performance or AMD will overcome intel idk.
