FX 4300 OC vs i5 3470

helltaimer · Apr 21, 2016

Hey guys! I just got gifted by a friend his old gaming PC, and I was shocked to see he had a Asus m5a88v evo MoBo with a FX 4300 and a CM Hyper N620 cooler. I currently own an i5 3470 with ASrock h61m vg3 MoBo. If I overclock the FX past 4.5 GHz, how much difference in performance is there between both CPU? Thanks!

The i5 should be faster because it has way faster cores and the technology is way ahead of it

We'll just use the single thread score:

1908/1412 = approx 1.35x

Thus the FX-4300 would have to be overclocked 135% to match the i5-3470.

*So you'd have to overclock to about 5.4GHz.

(The amount of gain in a game would vary though. Some would have minimal CPU bottleneck thus not gain much. Gaining over 30% from stock 4GHz would be the best-case scenario assuming a very CPU bottlenecked situation normally.)

The difference above 4.5GHz is probably not worth discussing since even if you managed 4.8GHz you'd only gain up to about a 6% difference in heavily CPU bottlenecked games. Because 4.8/4.5 = 6.67% diff.

(If you want the performance diff between the FX-4350 at 4.5GHz and the i5-3470 do the math yourself. Basically it would be (i5-3470)/(FX at 4.5GHz)/(4/4.5)

Thanks Photonboy! So basicaly I'm better off with the i5, correct? Thanks once more for helping me out!
