Ivy Bridge 3700K @ 77W TDP

[Idontcare]

we haven't even breached 5GHz out of more than 1% of current chips (and of those who do claim to have a stable 5GHz rig, most are running dangerously high volts for 24/7 use) and you're asking not just about 6GHz, but air cooled 6GHz

considering Intel capped the multiplier at 63 I highly doubt it, just because some SB chips are able to hit 5GHz doesn't mean we're suddenly going to leap forward another GHz, those really are the rare exception, just like there are an exceptional few 45nm chips that could do 4.4-4.5GHz

when we look at each process node, the realistic upper ends for stable computing on reasonable air cooling for quad cores have been:
65nm = 3.2-3.4GHz
45nm = 3.8-4.0GHz
32nm = 4.5-4.7GHz

I think we'll be lucky to see more than a 700MHz jump from SB's current practical range, so anywhere from 5.0 to 5.4GHz is where I'd predict practical air cooling will limit a majority of IvyBridge CPUs. Golden chips and/or high end cooling would likely net much faster clocks likely into the 5.5GHz range, but I think it will still be a pipe dream to expect 6GHz outside of supercooling and redonkulous volts

And if we really consider things like the fact that SandyBridge wasn't Intel's first foray into 32nm (they had a year to brush up on it with Westmere) and that Ivy will pop Intel's 22nm cherry, I think we should really be hoping IvyBridge gives us at least an easy 5GHz to at least break that milestone more than anything, it wouldn't be outside the realm of possibility for there to be a flaw somewhere along the line that severely limits Ivy's clocking potential beyond that of SandyBridge.

but yeah, i'd be surprised if we hit 6GHz on common air even by Haswell and believe it to be more likely that it will take Broadwell or Skylake to achieve 6GHz as a common milestone

of course I could be totally wrong, I'm just basing my guesses off of what we've seen from the past. Its always possible a new architecture throws us for a loop (although I doubt we see anything as drastic as Netburst from Haswell or Skylake) but that would only bring us to another point - would 6GHz even matter if its IPC isn't as fast as we're accustomed to? Right now another ~10% in IPC + a "guaranteed" 5GHz out of IB would be a solid upgrade from what SB "guarantees" us. Personally, I think 5.5GHz would be amazing, although I'm expecting something more along the lines of 5.2-5.3GHz (which would put it right in line with being 1GHz slower than its multiplier cap, much like how a realistic high end for Sandy is 4.7GHz, 1GHz slower than its 5.7GHz multi cap). But yeah, if IB can give us 6GHz on air I'd probably die from an epileptic nerdgasm.

BD is drawing the same power as its stated TDP 125W at stock.

While SB actual power draw at stock is nowhere even close to its TDP.

You can't compare Intel's TDP rating and AMD's TDP ratings, just like you can't compare there temperature ratings.

Intel's 77W/95W TDP rating is for system builders. It means in the worst case scenario the CPU will put out that much heat so the system builder needs to build a cooling system that is sufficient to remove that heat. The CPU on will probably never ever produce that type of heat unless you are doing synthetic testing.

AMD's rates there TDP based on there own ACP (Average CPU Power) rating. Which bases the TDP on the average power draw while running 5 typical applications of there choosing. Typical meaning applications a normal user will run. These aren't stressing the CPU to the max, it means for average use there 125W CPU would use 125W of power... if you use it for more then 'average' things it'll exceed the 125W rating.

This is why you are seeing BD draw 125W at stock and Intel's SB nowhere near its rated 95W (average typical draw will be more like 65-75W), the Intel chip should never draw more power then there ratings while the AMD chip will.

Whether TDP rating is representative of real chip power use seems to vary depending on the poster.

In reality, both Intel's and AMD's ratings are roughly in line with maximum power use. You can reach TDP specs with Sandy Bridge too, just not under the scenario most people use the computer nowadays. I bet if you have a power meter advanced enough to measure microsecond fluctuations in power, Sandy Bridge will reach TDP quite often.

it would be a little cheaper than the 2600K seeing as the cheapest SB-E is a locked cpu. Proberly more than a standard 2600 though.

On Sandy Bridge E, you can adjust the BCLK much higher than on regular Sandy Bridge chips.

2600 chip allows you maximum clock of:

110MHz BCLK(very lucky) x 42(+4 bins over max turbo) = 4.64GHz

3820 supposedly can do:

>125MHz BCLK x 45(+6 bins over max turbo) = 5.9GHz minimum, and its possible to push to 7.5GHz depending on how lucky you are with BCLK.

7.5GHz with 3820 is higher than what the unlocked 2600K can do, and 5.9GHz is close to 2600K's maximum already.

Is Ivy going to be an In place upgrade over Sandy? Same Price, Same Clocks, Different Model Number and Different process.

 

[Hypertag]

4.6 GHz OC is the new 3.6 GHz OC!

Come on, we were hitting overclocks bigger than that with Pentium 4 processors

Is Ivy going to be an In place upgrade over Sandy? Same Price, Same Clocks, Different Model Number and Different process.

it appears that way, biggest improvement is likely to be with the integrated GPU, although even if they manage to double performance, I don't think that will be as awesome as people were thinking it would be several months ago, I feel as if they were thinking it through. By the time IB releases it will have been roughly a year and a half since SB, and merely doubling performance would still mean its pretty mediocre and certainly wouldn't be good enough for the plethora of blockbuster games about to release this fall and coming winter...

don't get me wrong, the improvement will be welcomed, I just don't think it will be good enough to really impress

other than we can expect improved IPC, reduced power/heat/noise, and of course higher maximum overclocks. I don't expect Intel to ramp stock clock speeds too much though, not with AMD falling flat with Bulldozer, and not until they release IvyBridge-E. With SandyBridge-E and socket 2011 releasing in November it will still be a fledgling platform before IvyBridge is due, and it would be a bit foolish to undermine it with a plethora of 4+GHz processors for socket 1155.

ivy is going to be 22nm.
Sandy-E is 32nm.

Ivy-B will be the last step b4 hasswell.

Ivy-B will probably be flavored more on LGA2011.

1155 might get something... but i honestly wouldnt hold your breathe.

1155 spoiled you guys silly with price... 2011 will shatter ur hopes when u see the final tag.

Wait. Isn't Ivy set to debut on s1155?

The current HD3000 gpu can play 1080p video no problem for me. I heard that Ivy will be getting 50% more gpu performance from 33% cores. There go, Ivy should have 16 EUs compared to Sandy's 12. So does that mean that Intel will keep HD3000 moniker on the lower end Ivys with only 12 EUs?

Wait Again. Will SB-E be the only s2011 cpu till haswell? In other Words no 22nm shrink for SB-E?

Damn I'm confused.

there will be an Ivy Bridge E, but just like with Sandy Bridge, Ivy Bridge will be released for s1155 before s2011

what Aigo was referring to was that its more likely we'll see Ivy Bridge explored further on s2011 than on s1155, in other words its likely we see a jump from 6 to 8 core CPUs for s2011 with IvyB while s1155 likely will remain at 4 and not even see 6 cores, and that it wouldn't be until Haswell that we see mainstream with more than 4 cores.

^ nice summary and overview :thumbsup:

I agree that was excellent!

 

[Rifter]

Thats actually pretty amazing performance for so little power. Hopefully AMD is taking notes and can get the super leaky BD under control for there next gen chips.

 

[grkM3]

Intel has cut tdp down and also beefed up the gpu and clocks.Lets says these things turbo to 4.0-4.2 ghz and have a better gpu on board.I say that 77tdp is more than I expected and should run about 10 watts under that in real world testing.

does anyone know what clock speeds the first ivys will have?

I havent seen anything solid but im assuming they will be within 200mhz of the SB parts at least at launch.

The real answer i want to know is how leaky is the intel 22nm process and how will TDP ramp up with overclocking.
