Apples and oranges. Bf4 single player is heavily single threaded, of course Intel is gonna rock there, it's bf4 multi-player that really takes advantage of multi-core. Also, the i5 is probably 20w or so lower TDP, so with identical coolers running identical gpu', the i5 will OC faster, resulting in slightly higher fps. There are also, contrary to popular beliefs, differences in mobo's, not just cpus. Some mobo's use slightly better cmos, buss lanes, chipsets etc, resulting in faster travel of data between ram, cpu, ssd/hdd. All that too can result in higher fps. Sounds like your friend has gotten a good, well balanced combo, whereas yours isn't. TDP for your cpu is 63, I believe, so you could run flat out at 55 all day long and not even start to think about throttle backs
