To prevent a pointless debate, I just put both builds together. When people are playing multiplayer, the i5 definitely eats the FX for breakfast.
Hmm, maybe if you're just running everything at stock settings. I have an FX 8300, and from what I've noticed, that CPU basically fights against itself when the BIOS is left on the default settings. For me, Grand Theft Auto V would stutter even on medium settings because of unnecessary CPU throttling. The load was only at 50%, and the gap to Tmax was only about 35°C. And don't even get me started on the voltage—it was hitting 1.4V per core.
After messing around with the BIOS, I managed to bump it up nicely from 3.3GHz to 4.0GHz. I set the voltage to 1.32V, and under load, it even dips down to 1.296V. I ran Prime for an hour, and it stayed perfectly stable. The gameplay improved significantly, giving me about 15 extra FPS, which actually let me turn the graphics settings up a bit. Not to mention the boost in performance during multi-threaded tasks like After Effects.
And speaking of heavy lifting, I can play a multiplayer game and record in 720p simultaneously with the FX without any noticeable FPS drops. I think the FX still holds an advantage with those 8 cores, since roughly 4 are handling the game while the other 4 stay free.
So, it isn't enough to just cram a good processor into a build; you have to know how to squeeze out the best performance possible.
As for the 95W TDP, honestly, at 4GHz and 1.32V, my LC-CC-120 handles it easily, provided the room temperature is around 68°F and the case has decent airflow—which is way more important.
Now, as for whether the actual power draw of the processor hits 125W? I haven't a clue. 🤷
