I just use DX11...even with 270 I could be at 4.5ghz probably not even that is needed.. just fine and be capped 1080p 60fps
medium/highish settings...no frame drops/butter smooth...it's just ridiculously well optimized/usage.
I 've no idea. I have never played BF4. I just know that if an FX wants to be close to Intel in performance in CPU bound games, the more you see it loaded, the more it will be equal to its Intel counterparts. Contrary to many games that can't max out even a 4 core FX and where you see minimum differences between FX4300, FX6300 and FX8320, BF can load a lot, 8 cores. So this is why contrary to the previously mentioned games, you see the FX 8 cores, leaving behind the i3s.
There's no mystery. An FX 8 core user, should feel GLAD, every time he sees his CPU above 75% load. Up to 75%, his CPU will behave slighly better than an FX6300 (at the same clocks). The more the game can load 8 cores, the more you will see the distance from i3, FX4 and FX 6 cores. In hypothetical game that can load an FX8350 at 100%, the performance in the game will be roughly the same as an i7 3770.
Look at that:
- FX-4300 : 67 fps
- FX-6300: 88 fps
The difference is 23%. The theoretical difference, if both FX-4300 and FX6300 were loaded at 100%, should be around 30% (33% if FX6300 was at 3.8). What the 23% suggests, is that the FX-4300 is running at 100% load and the FX-6300 at something like 90% load. The 8350 SHOULD, if it was CPU-bound only, arrive to +25% plus (22fps PLUS, because of +2 cores and higher clock) compared to FX6300, so to 110 fps. Instead, it stays at 97 (only +9 fps compared to FX6300), which suggests, that it's even less loaded the FX6300, plus it has higher clock. The 9370 manages to take more fps, because of the higher clock.
Of course, things can't be 100% accurate, because all the above assumes that in all cases, the game can is only CPU bound.
In most games that use 4 cores, you see the FX4300 about the same as FX6300. Exactly because the 6300 runs at 75% load when the FX4300 is at 100%. BF4 shows each FX line separating from each other and closing the gap with the Intels, exactly because the game can load all cores heavily. Not just load many cores, but HEAVILY. If it was in position to load them all 100%, you 'd see the FX8350 battling out with i7 3770.
When in games you see your 8 core load at 50%, no matter how many cores have some load, in reality it's like you 're running an FX 4 core with more FPUs as bonus. Rejoice everytime you see your 8-core with loads over 75%, because it means you 're doing better than an FX6300 of the same clock.Edited by Undervolter - 6/2/15 at 11:56am
