intel i5 4670k vs 3570k vs 2550k who is get the lowest power consumption with same clock,and which is cooler with a same heatsink
July 2, 2013 3:52:05 AM

I would say ( this is my opinion )

i5-4670k - lowest power consumption - highest heat

i5-2550k highest power consumption - lowest heat ( due to soldered heatspreader )

i5-3570k - 2nd highest heat - avg consumption of the 3 cpu's

Depends.

Power consumption under load goes to Ivy Bridge. At idle (with a certified PSU) Haswell takes the cake.
Performance at identical clock speeds, Haswell>Ivy>Sandy.
Cooler, all are the same unless your overclocking.

can i do overclock in room temp higher than 30 deg celsius with haswell and air oc?

Yes, would suggest the Hyper 212 EVO

30c is 86f and your room temperature will be even higher?

That high of an ambient room temperature will be the limiting factor to how far you'll be able to overclock, I would not even consider less than one of the higher end air coolers or a better or best quality CLC water cooler, and I generally never recommend CLC coolers.

Your room temperatures will have you idling at approximately 10c higher than most and will greatly affect your overclocking CPU load temperatures and pretty much be the determining factor at how far you'll overclock any of the CPUs you're originally considering.

You must live in a tropical environment?

Yea, in a room that hot you will be limited in your overclocking unless you strap some beastly cooling to the chip. Even with my custom water-loop, when room temp is around 30°C my chip gets a bit too hot for my liking under load, and I'm not even pushing that big an overclock from my chip (3570k, 4.3Ghz).

If you don't mind me asking what would your approximate CPU load temperature be around 30c room temperature?

My ambient doesn't usually go past 24c but you know what kind of cooling I'm running, ambient is irrelevant, so I cannot even estimate a radiator loop temperature result, and a air cooling setup would be even higher that your estimate?

I do have these previous tests from the Below Ambient thread that I had performed at a 23c ambient at a 4.5ghz overclock with a 2500K.

Air Cooling;
Noctua NH-D14, w it's stock fans Idle = 32.75c, Load = 54.75c
Thermalright 120 Extreme 2 110cfm fans in push/pull, Idle = 32c, Load = 51.75c

Standard Water Cooling Closed Loop;
XSPC Rasa RS240 kit, Idle = 30.75c, Load = 50c
XSPC Rasa kit replaced with a Black Ice 240 Radiator, Idle = 30.25c, Load = 48.75c


I've never run at a 30c room temperature?

70°C is about my limit for letting components run under load, and with a 30°C ambient I was getting fairly close to that. At the time I was idling at 40°C as well.
This was before my GPU upgrade, cooling setup was an XSPC Raystorm 750 RS360 kit running Distilled.

On my old 212 EVO, wouldn't be surprised if I was hitting the high 80's in that situation.

4670K > 3570K > 2550K in power consumption
2550K > 4670K = 3570K in heat

CLC or Closed Loop Cooler, its a general term to refer to the pre-done liquid coolers like the Corsair Hydro series, Coolermaster Seidon, NZXT X60, etc.
Generally not worth buying, they typically perform the same as equivalent air heatsinks for $20-30 more. Its only once your getting to the very high end like a H110, or into Custom Water - CLC hybrids like the Swiftech H220, where you get performance you just cant achieve on air.

That's what I thought it would be, Thanks! :)
