sandybridge E, 180W??

[ed29a]

becasue most sandys are very good overclockers

Two (2500K and 2600K) out of 14+ processors is considered 'most'?

and if the tdp is this high

[Citation needed]

an overclocked 2600k will beat a 1000 dollar sandy e.

Did you see any benchmarks from reputable sources that compare SB-E to SB?

and forget what a 22nm 1155 ivybridge will do when overclocked probably 5.2-5.8ghz on air average

[Citation needed]

there was a 10 core 32nm sandy e for sale on ebay not to long ago,I wonder whats its tdp was.

360 watts?

[Citation needed]

why does every thread have to turn into ignorant fanboy accusations? I do not see that as having a damn thing to do with it. this is a rumor about high power consumption that is being discussed and whether it is AMD or Intel was not a factor.

I am talking about posts like the above one where people pull stuff out of their behinds and it's nothing more than baseless speculation and day dreaming and these posts come off as very fanboyish. And I won't even go into gibberish by Nemesis1 that is nothing more than 'La la la INTEL OWNS! La la la I can't hear you! La la la la INTEL RULES! La la la la!'

grkm3 has the inside scoop and assures that the SB-E will never go over 130TDP ever. If he says it, it has to be true...he's testing their engineering samples afterall.

You are the one who spread bs about sandy bridge using way more power than they do,not I.

And yes if there tdp is 130 watts they cant pull more than that at stock volts and clocks.

and to the poster above what are you talking about? go over to xtremesystems and see how many people have sandys running 5ghz linx 20 pass stable,there is a 50+page with plenty of samples and I didnt need 14 samples I have a 2500k and a 2600k and they both bench in the 5.1-5.2 ghz range.

I never said any of the crap you spread around,I am talking about stock voltage and stock clocks.The god damned 10 core older arch xeon e7 has a 130 watt tdp and its a 10 core 20 thread monster.

how is a 6 core sandy E(thats runs cooler and uses less power)going to draw upto 180 watts at stock clocks? while the 10 core xeon only uses 130,please explain it to us.

I think the article is a bunch of FUD, and SNB-E is not hitting 180W at stock.

What are your thoughts on AMD BD? I heard the BD destroys the SB-E while using 10 TDP with 10 cores and 30 threads, thoughts?

It is most certainly possible. Personally, I don't believe that they will hit 180W. However, I do believe that they will be at least 150W TDP if Intel is honest about their ratings. Remember, SB-E and SB are made on the same 32nm process.

the TDP will be 130 watts and I am 99.99% sure the cpu will not even use that. has ANY other i3/i5/i7 ever used more than its TDP rating at stock speeds???

 

[imaheadcase]

I do. Just like many others here.

Give me a break. Its time to let go then.

Why are you bringing up BD in a sandy E tdp thread? everything you post is completely made up in your baised hate towards Intel.

Ill buy BD when it comes out and tell you how it does

Simple math:

i7 2600K with 4 cores, 8MB of cache uses 95W. Oh, wait, this includes the IGP, so it is really an 80W part (see: http://www.newegg.com/Product/Produc...eon%201270).

A quick, back o' th' envelope calculation gives us (6/4)(80) = 120W.

Add in a few watts for the added PCI-E lanes, and we're about at 130W. 180W my tush!

You forgot about the quad-channel DDR3 controller and the near doubling of the L3 cache. Also, I'm not sure that the IGP even accounts for 15W of the 2600k's TDP. Can you show me a comparison of the power load with the IGP enabled and disabled?
edit: Actually, I'm not sure of how you'd measure the TDP of the IGP because you'd need a dedicated card to disable it. :hmm:

 

[scooterlibby]

and please stop using car analogies

if any thing SandyBridgeE will be more like a dump trunk capable of winning the Indy 500 however that doesn't mean the 1155 SandyBridge or IvyBridge CPUs won't be able to keep up with or even give SBE a run for its money when the extra cache/cores/threads/lanes/etc aren't utilized

Haha I loved this pivot from admonishing people for making car analogies to making one of your own. Breakneck speed!

 

[Abwx]

please tell us how a sandy e can consume 180watts when its tdp is 130watts?


I dont see this happening.

TDP is a thermal envellope , it has nothing to do with maximum
instantaneous power draw wich is the peak power that can be
drained during short times and wich exceed largely the TDP.

TDP = thermal design power , wich is just the power that the heatspreader
must be able to dissipate...

Datasheets normally contain the thermal design power (TDP), which is the maximum amount of power the cooling system in a computer is required to dissipate. Both Intel and Advanced Micro Devices (AMD) have defined TDP as the maximum power consumption for thermally significant periods running worst-case non-synthetic workloads. Thus, TDP is not the actual maximum power of the processor.

http://en.wikipedia.org/wiki/CPU_power_dissipation

 

[Vesku]

Intel turbo involves temporary spikes in power use and thus thermal output, correct? It seems that Intel is wanting to make sure there are no odd turbo crashing incidents, which means even in turbo they aren't planning for it to hit or exceed the recommended minimum amps.

 

[darkswordsman17]

First, people stop trying to directly compare power draw and TDP, they are correlated but not directly so (i.e., a 130W TDP rated CPU does not mean it can only pull up to 130W).

Chill out, he was very clearly making a joke.

You assume that they aren't having issues. I think that is why you need to reconsider. I'm not saying absolutely its true, but its definitely a possibility (as is it being a bogus rumor). Intel delaying it to 2012 though does not bode well for them not having issues. Just because its based on Sandy Bridge's [excellent] cores does not mean its easy or will be free of problems (even if Intel can work them out so that they are not problems in the final production CPUs).

Really though, people do need to stop using car analogies. I see it a lot and people generally only prove their lack of knowledge of cars as well as whatever they're trying to relate it to. Its not just on here either, I see people using it for everything.

Yeah bro I hate intel so much that my last 8 PC's were intel based.....you know I also hate nvidia, now there's a cancer that needs to be eradicated from the world.

My 2600k at 5 ghz pulled under 130 watts at full load with the igp turner off.

Its rated at 95 tdp and from my own testing there tdp is very close to the actual wattage they pull.if anything there about 10-15 under there tdp from intel in rwal world testing

Even if you turn the IGP on , power comsumption will not rise
during phases where the CPU part is at full load as there s
a mechanism that reduce the IGP frequency and bandwith
to give more room to the computing part.

Hence, a fully loaded 4C/8T Sb will likely consume about 90W at least
at stock frequency even with the IGP disabled.

Transposing to a 6C/12T SB-E , this would increase power draw
to 135W , and likely a little more since the IMC has more memory
channels and surely more cache.

That said, a slightly lower frequency than the 2600K should
allow to be on the 130W TDP envelloppe.

All will ultimately depend of AMD s Bulldozer perfs , wich will
be used as reference to decide the SB-E TDP positionning.
