> no, i5 4570 is not a beast. It can be easily overthrown by the cheaper FX 8350. Though gaming performance is slightly better in case of Intel.
> Now about your calculation:
according to you:-
money saved annually= Rs.6500 => units consumed annually(considering Rs.6/unit)= 1083.33 units/year = 2.968 units/day = 0.12366 units/hour = 123.66 W of power difference between i5 4570 and FX 8350
Are you saying that you PC is running a render while scanning the PC for malware and compiling Firefox at the same time 24X7?
Check here: AMD FX-8350 - Power Consumption | bit-tech.net (althpugh the comparision doesn't involve i5 4570, we can get an approx result by reducing the power consumption of i5 3570k by 20-30%)
At idle, both consume almost same amount of power and even at load there is 96 W of power difference. Now this can lead to ~5k cash saving, but WHO RUNS THEIR PC AT 100% LOAD 24x7x365?
No game used 100% CPU, so anything but Prime95 or non hardware accelerated rendered running 24x7 can make such difference.
In a nutshell, you'r calculation are nowhere near real world PC usage scenarios.
> Overclocking is very safe now. You cannot burn a CPU unless you put it on fire or there is a manufacturing defect in wither CPU, motherboard or PSU.
Once overclocked, it wont underclock when it's idle [as in the case of turbo boost]. Also as far as i remember i pay around 8.5Rs/Unit [noob reliance]
Here are my calcuations:
(6500/8.5)/365 = 2units/Day
On an average i play around 3-6hours per day on weekdays, and 6-14hours per day on weekends..So avg time playing = 6hr per day
So conserding i5-4570 [which is around 67.9W at idle] and an fx 8350 overclocked to 4.5ghz which will be around 135.625W [according to the link u posted]
Difference = 67.725 difference = 0.067725 units/hr for 18hours = 1.22Units/18hours
Now rest 6hours when i am playing games assuming a 50% load on an avg theres a difference of (307W-112W)[at100%]/2[for 50%]
[Yes i know this is an avg and i am pretty sure consumption will be +or-10%]
Difference = 97.15W = 0.09715units/hr for 6hours = 0.09715*6 = 0.583units/6hr
1.22+.583 = 1.803units/day = 658units/year = 5600rs
I used some other source to calculate power consumptions so i got 6500rs
