Better performance for level of noise - 2500k or 3570k?

[NAC]

I do about 50% gaming and 50% encoding / video or picture editing. I don’t want to spend the $$ on an i7 unless another $199 sale shows up. I plan to overclock lightly – I’d be happy with whatever I can get on stock voltage or perhaps a tiny above stock voltage. From what I’ve read – the 2500k should overclock slightly higher, but have slower performance per clock – so they are basically a wash performance wise. Price wise they are about a wash depending on what is in stock at Microcenter. I’ll need to buy a motherboard, so the 3570k would be slightly cheaper if/when they get more Asrock’s in stock near me.

So everything appears nearly equal, except perhaps heat. And the 2500k seems to run cooler, hence should be quieter for an air HSF to cool. Is that the case for light overclocking? Say 4.2/4.4 ghz – will Sandy run cooler? Or is Ivy cooler at light overclocking scenarios?

Note that I won’t use the integrated graphics, and don’t think I’ll use Quick sync.

i'm in the same dilemma

They will both run around the same temperature, IB doesn't scorch until you go over 1.2v. Stock voltage will get you to 4.3-4.4 on IB, and 4.4-4.5 on SB, which favors IB because of better PPC. IB will also use around 30W less at that clock speed.

If you're doing photo editing and video encoding, I strongly suggest you go with the 3770K.

Where are you seeing the 2500k runs cooler? The 3570k chip should theoretically run cooler with the lower power consumption numbers, as compared to 2500k.

I'm in the same dilemma too. Chances are I won't be overclocking my new CPU in the first year. Maybe only later, when new games demand more of the CPU. And even then, I will probably not change voltage.

So I guess the i5-3570K would be slightly better at stock speed and stock voltage.

OTOH, prices for the i5-3570K were ridiculous over the last days (in my country). i5-2500k is ~190 euro in most webshops. Those same webshops asked 240+ euros for a i5-3570K on Sunday ! Prices are already dropping. One webshop dropped to 202 euro, a few to 210 euros. I hope this trend continues. Until the i5-3570K is at the same price as the i5-2500K. I have the patience to wait a few more days, and see prices drop under 200 euros. I just hate paying even a euro too much in this case, where webshops are trying to wringe a few extra euros out of their customers.

I bought a gtx680 on release-day. That was a smart move. For the i5-3570K, I think the smart thing is to wait a few more days.

The difference is in temps, not noise, CPUs don't make noise. If you get a quiet cooler, the noise will be close to inaudible so it doesn't make a difference.

Only works that way theoretically. More closely packed cores resulted in worse heat dissipation despite the reduction in power consumption.

The smaller the die size, the hotter it will get. Stick with your 2500k , gosh your set with that CPU for years,, all you do is upgrade video card every 3 years or soo... and get a SSD if you dont have one now. gl

To be clear - I don't have a 2500k now. I have a q8300 and want to upgrade to either a 2500k or a 3750k.

I know that an i7 would render and encode faster, but I don't want to spend the extra $100. I'm used to starting a render / encode and then walking away - if it takes 10 minutes or 15 minutes doesn't really matter. In photoshop the gains are more immediate (in seconds as you sit there), but the differences are also smaller - between i5 and i7 only about 10% increase. I do less photo editing, so again I'd rather save the $100. In both cases - I do it only for for recreation.

Now, the trump card is price - if I see a 2600k for $199 again - I'll buy it and be happy.

I think you will be quite happy with either one. Check out the heat output from your old chip. Huge improvement either way. Comparatively, the diff between the 2500k and 3570k are miniscule.
