Isn't a peak power draw of 180W to be expected since Intel's Turbo Boost is allowed to increase power consumption beyond the TDP until it hits a temperature limit? That doesn't mean it will draw 180W for any extended periods of time.

well the 10 core xeon E7 is 130w @2.6 ghz,so by intels own specs of 22nm trigate they should be able to cut power down by 50% for the same clock speeds.

Im willing to bet that a 6 core 22nm wont be over 95watt nevermind 180

enless stock speed is 3.7 and these turbo to 4.7 the 180watt is just to much without an on board gpu

Ivy Bridge will be 22nm, but Sandy Bridge E won't be, right? I am getting confused here, so please correct me if I am wrong, but Sandy Bridge E is not Ivy Bridge, and is not 22nm. Why do you keep mentioning 22nm and tri-gate?

Maybe they'll sell a software upgrade that will lower the power consumption?

because socket 2011 will get Ivy bridge,Ivy bridge was built from day 1 only for socket 2011 but then intel changed there minds and made them for 1155 also.

1155 was never supposed to get ivybridge from the beggining.

and ivybridge is a 22nm shrink of sandy and there isnt supposed to be onboard gpus on socket 2011,180 watts is not going to happen even at 10 cores

I'm aware of that, but that still has no bearing on the topic that I can see.

We are talking about the rumored TDP and "burst / peak TDP" of Sandy Bridge E, and all SKUs mentioned are Sandy Bridge E, all 32nm parts. Nobody, but you, is mentioning Ivy Bridge, 22nm, or tri-gate. For some reason, you keep on talking about it, especially in relation to the TDP. Why? We are not talking about Ivy Bridge. We are talking about the high-end 32nm parts, not the 22nm shrink.

because the high end 2011 parts will be 8-10 core ivy bridges

6 core sandy E will be on 32nm and intel already has a 10core 32nm at 130watt

there 8-10 core high end will be ivybridge around september next year

intel wont wast money making 8-10 core 32nm,you can buy a 10 core chip now but its 6,000 bucks for 1 chip.

450W video cards... 180W CPU's... and they call this progress? :rolleyes:

This reminds me of American cars in the 70's.

Well, American V-8's of the 70's got 7 MPG and had 110 HP.

At least with these things you get powa to go along with the thirst at the wall.

:awe:

And? The rumor (the linked article) was very specific - Sandy Bridge E, and even mentioned the supposed SKUs - all 32nm.

There is no Ivy Bridge rumor here. All the TDP talk, 130 - 180, is about Sandy Bridge E and 32nm. This has no relation to Ivy Bridge, and it makes no sense for you to bring it up when people are talking about the plausibility / implausibility of the supposed TDP regarding 32nm SKUs mentioned that are Sandy Bridge E.

intel gives tdp to board makers for there highest power drawing chip,these will be the 6 core 32nm at launch and those will consume the most power.

Knowing that there next shrink will be 22nm and on the SAME socket and also knowing that there already is a 10 core 32nm chip at 130watts puts this rumor to rest.

Yes, and that is what the rumor is about - these hex-cores @32nm that will consume the most power. We have no idea what clocks and turbo are yet, atleast none that I have seen mentioned, and they are big factors to TDP.

22nm, not related at all. Does not affect possible TDP mentioned in the rumor. As for the 10-core Westmere, that is a MP server chip, and so is a different ball game. Server clocks can be much lower than their high-end enthusiast desktop brothers.

If the upcoming Sandy Bridge E chips are clocked much higher by default (including higher turbo), then TDP can easily be 130W flat for the highest-end SKU, with possible peaks greater than that, regardless of what 22nm offering they will have.

I think 6 core will be 130watt,I was bringing up ivy because thats where intel is going and where they will add more cores.

If a 4 core 2600k with onboard gpu is 95 watt I think 6 cores can be done at 130 or so without a gpu.

180watt at stock clocks is a little over the top,enless these are running at 5 ghz

Agree. The comparison and conclusion isn't that straightforward, though, because clocks are missing. 2600K is at 3.4 stock with 3.8 single-core turbo. If their high-end pushes stock clocks to 4GHz+, add good turbo, then add 2 more cores, it is not unimaginable to exceed 130W for a short time. Again, I'm not buying as high as 180W peak consumption in rare cases (even if just bursty), but I can see it gobbling up far far more than current SB parts. After all, their market for these processors don't care. They'll be using 700W+ high-end PSUs with highest-end air-cooling or water-cooling, it's not like they will be selling Sandy Bridge E in high volume for normal desktop users.

Even if it did eat 180W, as long as the performance is there, the enthusiasts in this price range won't care, because their PSUs and cooling system won't skip a beat. So even if true, I don't really see this rumor as bad news or anything. Nice to talk about, but for the target market, hardly a concern. Take an overclocked 2600K. With HT on, and clocked at 4.6 GHz or higher, what's the effective TDP then? Probably 180W already. As long as Sandy Bridge E delivers the goods (performance), this rumor is a non-issue.

Intel has never released a chip in the last 6 years that uses its TDP . SB has IGP . The only people going to spread this lie are AMD fans . When is BD going to be released Again .

I am very happy about the post tho . As we had a pool going on what member here would spread the lie . As worded in the topic . I won . BOb , Betty and Dar lost I won $300 . Thanks for the post. SB-e is a server chip if it used 180watts intel would be handing AMD the server market. Only mentally deficient people would believe this would believe this.

I guess if they can try and spin something negative against Intel, this would be it.....

Arent there rumours that BD will have a high TDP and ship with a water cooler?

I have a feeling most people arent going to be able to afford this anyway, and if you can, you arent going to fret over a few extra watts.

No? The SKUs mentioned here are Extreme / High-End Desktop parts. There is no mention of server parts that I have seen.

It's all extreme / high-end desktop parts, so TDP does not even remotely matter as far as I can tell. If it performs much faster than anything else, it could have a 180W TDP and it wouldn't matter to the enthusiasts at this level.

Like I said before, it's completely a non-issue even if true.

I believe SB-E will be 130W and i have no idea what that 180W consumption they mention on VR-Zone link is.

I do believe that the CPU alone will have higher power consumption than 6-core Gulftown, but overall consumption of the platform could be lower due to more I/O logic that have been integrated directly in to the CPU die of SB-E (PCI-e etc).

So perhaps the CPU will consume more power but the platform overall power consumption will not be that much higher than X-58 and 6-core Gluftown CPU (yes i know we have quad memory controller that will add more power + PCI-E Gen 3).

The Core i7-3930K looks like the CPU for me if I can get it <$500 (MC deal anyone?) :)

Otherwise, I will wait and build when IB-E arrives. I want 6 cores+ to be a real upgrade over what I already have today.

Way more! 1st generation i7s pull ~ 285-340+ Watts at 4.0ghz+.

My i7 860 @ 3.9ghz pulled 275 W.

That's total system though, not just the CPU. 180W for just the CPU is borderline crazy. Although, if the performance is there it doesn't really matter much. Also, will be interesting to see what their idle power-usage is. That is what is really important anyway. Assuming perf/watt isn't low (why should it be?) it doesn't really matter how high max power-consumption is, as long as it sips when you're not using it.

I hope they put out a 4 core ivy with no gpu on s2011.that is going to be the best bang for the buck and should overclock like mad.

It will be like a 2600k now with quad channel and 22nm

It sucks because i read that intel might not sell fully unlocked low end ones because it will reuin flagship sales.

i7 3820 is ever so slightly less expensive than a 2600K? I suppose the lack of overclocking would make it less attractive for enthusiasts. Are all of the above hex, or is the 3820 a quad?

I'm also confused by the naming scheme. I thought the "2" in 2600 meant "2nd generation", so I expected "3" to belong to Ivy Bridge, but instead they are going ahead and giving the "3" designation to high-end Sandy Bridge parts, instead of 28xx and 29xx?

3820 is a quad + no overclocking = fail.

http://www.cpu-world.com/CPUs/Core_i7/Intel-Core i7-3820.html

Basically, the 3820 is the place-sitter for that mythical person who wants to buy a 6-core capable motherboard now but only wants 4 cores, at least for now. Then, eventually, you could use this somewhat-outdated platform with a 6 core ib-e.

Yeah, 3820 seems to be for that small subset that just wants quad channel memory and PCI-e 3 but has low cpu demands.
