Intel Ivy Bridge discussion thread.

[Idontcare]

If they're right about the improvements at 1.0V then we're going to have some nice quad core notebooks that last all day. Hopefully this iteration will mark the first celeron/pentium quad.

22nm xtor's and IB do nothing to address the other 75% of the power consumption of a mobile product - the LCD, the drives, the ram, the remaining chipset and components on the mobo.

Intel is doing their part, but they aren't the sole limiting factor in getting to 12+ hrs of usable mobile compute time.

I don't know the current efficiency of LCD screens, but they may be at their practical limit.

22nm on lga2011 is serious business guys.

There are plenty of notebooks that can claim all day battery life. But there is no way any of them are going to play a game like League of Legends all day long. With IB it just might go from 3 hours to 5 hours though. LoL isnt a terribly demanding game, it is just a constant midrange load on both a cpu and a gpu. I doubt there are many notebooks that can even run it for 3 hours.

20% performance improvement on a per-clock basis isn't happening. Ivy Bridge is a die shrink. Realistically, we'll see improvements between 0% and 5% per clock.

Ivy Bridge is still Sandy Bridge architecturally.

That is spot on. Conroe to Penryn showed an average 5% increase in performance per clock and most of that was in apps that used the new SSE4 instructions in Penryn. AFAIK there aren't any new instructions in IB.

What would be fantastic is a 6 core socket 1155 IB maintaining the thermal envelope of the 2600. Of course that would devastate Intel's high end chips so I'm sure it won't happen.

Hmm that would be disapointing honestly.
I have Asus UL30VT which uses 45nm core 2 CULV with switchable GF210/Intel graphics and I'm getting 7-8 hours of normal usage without problems and 2-3 hours of World of tank gaming (100% constand load on gpu and almost 100% on cpu often) .

This.

Why I think Ivy Bridge will bring minimal benefits on battery life:
-TDP specs only affect doing something high end on battery, which for most us wouldn't be doing and plugged to AC. That's gaming as well, since one of you mentioned LoL.
-TDP in non-high end scenarios are just about cooling. Lower TDP, smaller form factors are possible
-Idle, web surfing and video playback would maybe gain 30 mins on Ivy Bridge
-Point of Ivy Bridge will be to drastically increase performance on low voltage platforms like 17W chips

Hmm that would be disapointing honestly.

But Ivy Bridge will be few times faster than that system. Performance is inversely related to battery life. Yet performance increased massively without sacrificing battery life. For others there's AMD's E chips and Intel's Atom.

2500K = $179.99

That is the cheapest unlocked CPU Intel has sold in the last how many years?

I know, complaining that the 2500K is too expensive just makes you look cheap. The 2600K is also stunningly reasonable in my view anyway. The 2500K eats anything AMD has. Sometimes things are artificially cheap, or cheap for a reason - because they're not competitive. Sufficient, yes. Nothing wrong with that. But if you want more, I think Intel's set the prices about right. Hope that continues.

 

[zlejedi]

$200 is a crapload of money for developing countries.

In Poland it costs around 20% of average monthly salary. If you go further east it will be like 50% or even more.

i3 530 was quite popular here last gen and if we had unlocked i3 Sandy i bet it would be very popular cpu for gamers.

But normal user doesn't need more performance.

core2 @1,7 Ghz is running all every day task perfectly.

I only lack performance when I'm runnning SVM with oracle in linux virtual machine on it or when gaming.

And it miles ahead compared to atom/E chips

 

[IntelUser2000]

Oh, I don't think you need to worry about that.

Want is the new need. 30 fps stable not enough, gotta be 60, gotta be 100. 36-inch TV? Not big enough, 60-inch the new 36, maybe even a ultra bright projector to make it as big as wanted.

For those that can completely control the urges, future Atom and Brazos would fit the need for better battery life vs. better performance.

Technically, IB does allow low-voltage RAM, so that helps. But your point is well taken. I wonder if Intel will come out with a 22nm chipset too?

The lowest-power-usage notebook would have:
- Ivy Bridge CULV
- LCD with active LED backlight, so the LEDs turn off for areas of black
- an SSD
- LV RAM
- and not much else.

Technically, AMOLED might be lower-power than LCD, but I don't think they're making affordable panels that size yet, are they?

What makes you believe it won't be . The only public information available on intels IB IPG is on a chip running 2,2GHZ cpu 400/900 IGP This was said to be a GPII Intel also has GPIII. for notebook class.

Didn't was see a leaked document that said the level-3 graphics would be on the ULV CPU? I refuse to believe the fastest GPU will be on the ULV chips.

My guess is that it is a sort of situation where perf/watt for that part is the highest out of all of them, and so the model number (at least the internal model number) is the highest.

Are we mixing up Haswell with IB here?

 

[ed29a]

Can't see this posted elsewhere, IB-E news. Socket compatible with 2011, coming Q4 2012.

How did you go from that to graphics on Haswell? Sometimes your posts are really confusing to the readers.

Good example on the GT3 on ULV/mobile vs GT2 on desktop from another thread:

Also, are the A4 APUs true from-the-fab dual cores, or are they full quads with disabled cores? Strange that the desktop A4s are 2 cores/160 SPs, and the mobile ones are 2 core/240 SPs. Makes me go hmmmmm:hmm:

Integrated graphics are FAR more important on laptops due to the difficulty of being able to upgrade the components.

You're right, of course that's all relative. $200 IS a lot in many places. All of AMD's CPUs are more than good enough for anything you'd need to do in any case. Llano is great and so are their Thubans. If I had $100 to spend on a CPU, I'd be looking really hard at AMD anyway.

I am excited about Ivy though. I've decided to wait on a RAM upgrade until Ivy, when I can ditch my big-ass air cooling and go water for the first time. My push-pull CM 212 interferes with my RAM slots, so an H70 or H80 (or Intel's offered cooler) will be in the works.

Did they ever figure out the EUFI (sp?) compatibility concerns with IB on SB platforms?

 

[Hulk]

I'm getting the feeling that IB won't be too exciting for the desktop but the reduced thermal envelope will be a big advantage in notebooks.

How about ultrabooks with "real" dual cores ~3GHz instead of the ultralow voltage 1.6GHz chips we're seeing now. Or the middle class 14" notebooks and even slim 15" ones like the Dell XPS 15z possibly being offered with an IB quad core?

 

[ed29a]

2500K = $179.99

2500K = 179$ (*)
(*) In the USA and if you live close to one of the 23 or so MicroCenter locations.

Fixed it for you.

 

[ed29a]

Can't that be fixed with bios/uefi update? Most Z68 boards are supposed to support IB, so I am guessing mobo makers must have done something, I am guessing.

^ that was everyone's expectation/assumption since time-zero, but the skuttle-butt that made the rounds was that there was something intrinsic about uefi that precluded the possibility of taking a eufi that was SB compatible and making it IB compatible.

I don't know jack about it other than the observation that when those rumors were circulating there were no tangible arguments made at the time for why the rumors would be BS.

[podspi]

Impressive that the top-bin TDP will be 77W. Thoughts on why that might be? Do you think Intel just believes they don't need to push TDPs higher, or might it be that too much voltage degrades the CPU faster than before?

Either way it's great. Can't wait for the ULVs and Atoms based off 22nm

$200 is a crapload of money for developing countries.

it is, but as with all products, intel wants a return on investment for the R&D that went into it. Getting that means setting the price for a while as Intel for sure do not want to sell at a "affordable" level in developing contries were it would be cost effective of them to then ship the chip back to western countries and have the middle man make the profit instead.

If you want it, you can get it. Personally, it makes a far better system than region restrictions (ie: DVD's) and the hassel of enforcing them.
