More Ivy Bridge benchmarks - Sandybridge comparison - 3770K vs 2600K (Performance, temps etc) "Couple Of LN2 scores are up" - Page 59

post #581 of 690
I'm seeing some odd results of the 3770K having a lower idle and load power consumption (stock), than the 3570K, which doesn't tally with the higher temps on the 3770K or with the 95W vs 77W stories.

Yep, that makes sense. Marketing<>Honesty. Market=Lie creatively.

The guru3d shows a max core temp of 89°c on core#2 but judging by their prime window .. ..after 6 mins only.
!
Yay. I have though the same.
Imho, Guru3D is lying to us. 80ºC at 4.9GhZ and 1.4v on air when everyone else on earth is showing higher temperatures, with better cooling solutions and less frequency?
I just don't believe their results thumbsdownsmileyanim.gif

it is doing 90C @ 1.4V 4.9ghz, look at max temps http://www.guru3d.com/imageview.php?image=38170 I guess this seems quite possible with a d-14 , i dont think anyone wants to have a chip that goes that hot under load though tongue.gif

Ya, little bit of a misquote from Psyco.

Can only be told with time. It's the metrics and someone actually doing it. I agree 90°C 24/7 sounds nasty bad and I don't think it's plausible, but if the architecture can stand it for several years without degradation then it's a moot point. Should warm up your room/office to boot in winter wink.gif. Even if it does degrade after 2 years, pretty much everyone on these (enthusiast/overclocker) forums will be likely to swap out processors quicker than on a 2 year cycle, so might as well cane the CPU whilst you have it in your rig if it lets you - just hypothetically you understand and not saying IB will -

well degradation isnt going to happen instantly after 2 years, but graduatly over the course of ~2 years with it being "broken" after 2 years. with more demanding games coming out its theoretically better to run it at stock first year so you can burn it 2nd, but then again id rather run it at bit lower speeds/voltages/temps, if it can run like that for 24/7 3-4yr+

meh temperatures =/= heat output, an x79 @ 65C(lets say 4.5 ghz@1.3V"just guessing these, dunno the actual overclockablility from these chips but you get the point") will probably heat your room up more than a 3570k/3770k @ 90C(4.9@1.4)

for the one that was asking earlier, with the NDA lift intel published their technical documents about the processors.
VID range ~0.25-1.52V
TjMax(only reference in their thermal design document is the assumed 99C, so i guess its 99C
TjCaseMax 67.4C for 77W

thermal
datasheet vol. 1

They are just using 99C as an explanation for fan control, tjmax isnt 99C. Again each cpu has that value software accessible, so can be read directly off cpu via MSR. The ones have seen so far have been tjmax 105C.

What do you use to read msr?
More specifically, is there something written for Win7?

@Eggy, Rge

Found some throttling tests. Trip @ 104C, Tjmax/Prochot @ 105C
