Well I'm not really trying to get in a fight but the fx4300 does in fact have 4 real cores. the virtual cores are the same thing as intel's hyperthread's. Back to my point. This site is meant for people to find cheaper parts for they're computer's that can do the same as an expensive part does. So I will clear up any confusion. The FX 8350 is indeed a nice chip but it comes with the burden of keeping it cool enough to pull off the ipc's necessary to complete tasks. It runs at 125 watts. The FX 4300 can easily meet those clock speeds at a lower tdp, therefor staying much cooler and allowing the chip to pull off the ipc's in the first place.
When gaming, AMD tends to do better with newer games, because newer games use multi-threading which is right up AMD's alley sense it uses virtual cores. Intel uses physical core's and no multi-threading sense there are no virtual cores involved. Intel is a great CPU for older games that do not use multi-threading and AMD would do a bad job because it's single to single core ratio is weaker than Intel's. The only thing Intel CPU's do better than AMD on, are overclocking and higher benchmark ratings. Also, Intel's single core vs an AMD's (virtual Core) blows AMD out of the water. You are right in saying that there is no real difference between Intel and AMD when gaming, because on the level that Intel beats AMD, would not be noticeable. However, when not gaming say; 3D rendering, Intel will be far more superior than AMD because programs like Cinema 4D use each core to render a set of pixels. I assume you could see how Intel's REAL physical cores could easily dominate AMD's virtual cores. Anyways, happy gaming oh and I would recommend getting a second 970 for SLI, it eats up GTA V like it's minesweeper lmao.
ive had both processors. the 4300 is the right one to get trust me. i have a core i7 6700k also, guess what? the i7 and fx 4300 are both coupled with 16gb ram and a gtx 970. they both have the same cpu cooler same power supply and same ssd. when i run any software including steam games i can tell no difference at all. infact when i run the ps2 emulator it runs better with the fx 4300 because i can run higher clock speeds and the fx has more instruction sets. the only thing you need to do to get great ipc's out of the fx chip to match the i7 when gaming is keep it below 45c. no probem! get the Cooler Master Hyper D92. as long as you install it right your fx 4300 won't reach 40c under %100 stress. mine don't. these are non bias facts for you to use. any troll can get on here and speculate. im playing modern games in full 1080p with all settings in ultra. the fx 4300 is all you need. your welcome! i spent the money and tested in real world playing fallout 4 mkx and gta 5. i can play all of them in 1080p in ultra with the fx 4300. there you go
