Fx-6300 vs I5-6400

[Planewings]

So I'm thinking about buying a new PC and have seen some decent rigs in my price bracket and it comes down to these two processors(I'm upgrading the Gpu later so that doesn't really matter) I have seen alot of different sites comparing the two saying that the i5 is better but the fx has more GHZ I was wondering if someone could clarify why the i5 is better.

Even comparing a fx 8350 to an i5 is bad just in general. Let me give the run down of all the cons.

Fx-8350;
Hot -- 50C in bios. :'( of course this is running a stock cooler. Still though 50c in bios?!?
200W at load
Slow to run anything that isnt specifically designed for multicore
Pros; cheap.

Any Intel newer than what you can find in an old Macintosh - its a joke chill;
Isn't nearly as hot as the fx-xxxx
Uses 100-150W less than fx-xxxx
Runs everything light years faster.
Cons; not as cheap


Honestly I have an amd build. I know the torment. I'm forced to use 200W over what normal people use. I have a 700W psu for a system worse than people with a 500W. Its stupid. I say "Oh I have a 700W psu" and people say "OMG SLI CROSSFIRE BURRR" and it's not. I have an fx-8350 actually. That's exactly how that goes.

I agree the i5 is a better CPU at this point, its newer and faster. Buying into AM3+ and any FX is a bad idea when its a near dead socket being replaced soon by AM4 and Zen.

That said, to mention a couple things:

200w sounds a bit excessive for just the CPU alone, even for an FX 8350. Are you sure thats not for the whole system?

50c sounds about right to be honest, with a stock cooler. I get 55c idle with an i7 930, also on stock cooler. Stock coolers are just loud, worthless crap in general, be it AMD or Intel ones.

700w again sounds a bit excessive. A good quality 500-550w unit can handle an FX system just fine. Same for Intel, around 500-550w. Higher if you want crossfire or SLI.

Nothing wrong with an FX 8xxx
But an FX 4xxx/6xxx just totally sucks.

I built my PC about 3 years ago - AM3+ socket mobo with FX6300+ CPU. Like yourself, I went with this option to fit a budget. Now, I'm kicking myself.

The FX6300 can't keep up anymore. I could upgrade to something like a FX8370E on the current socket and see some modest gains for around £150, the other (and preferrable option) would be to switch to intel, but that is basically a rebuild and will cost something like 2.5x the price once a decent new mobo has been factored in.

AMD won't be releasing any new CPU's on the current AM3+ socket, so what's on the market now is all there ever will be - That leaves very little headroom for future upgrades if you go with the AMD option and even if you do, the FX series CPU's are not as fast or efficient as their intel counterparts (albeit quite a lot cheaper).

This guy is spot on. Yes - The FX8350 is rated at 125w, the FX6300 at 90w.

As for temps, my FX6300+ is currently overclocked to 4.2ghz on stock cooler idleing at 37c.

700w psu is way over - the GPU will be the major factor in PSU requirements not CPU. A decent 550w PSU would be more than adequate.

if you are gong to overcock fx
1. make sure the mobo has a 970-990 chipset
2. make sure the mobo has a vrm config capable of overclocking (4+1 with heatsinsk or better)
