Ivy Bridge Vs Sandy Bridge on a laptop

Should i wait for the ivy bridge processors? If so, when will they be released? Will be there be a significant difference between the two?

Alright thanks, im sticking with a sandy bridge since the ivy bridge doesnt really have different archiecture

 

It does in a sense it doesn't. In other words it does have a new architecture by being smaller in terms of dies and that it packs in a better iGPU etc. However realistically, it is only like .2-.4 GHZ more per clock, so overall gains are like 10-20% at most.

 

im not so sure but i think it also provides some technology not found in ib like ssd caching, better igp, ocerlcocking across the board. cmiiw of course

 

It's the same architecture, just a die shrink with the requisite bump in frequencies and maybe a minor tweak or two.

The real bonus is the move from the HD 3000 to the HD 4000 gaphics core on the chip because it has 16 vs 12 execution units.

 

Yeah i dont think i can wait five more months for a 10-20 percent increase haha! Thanks for the replies. NOw i just have to wait for the 7200 rpm hdd availability on the customizable HP i want. Dang those floods in thailand

 

The performance gain isn't much but those CPU's are gonna generate less heat which is very important and also take less power to save battery.
The sandy bridge CPU generate lots of heat and for some laptops might cause throttling . AW M14X for example has heat problems because the SB generate much heat and it's case is small. Therefore, for laptops with small cases Ivy is really important. Also I heard its going to support USB 3.0 native.
Maybe overclock for laptops will be open , at least I hope so. When Kepler /7000 series are out , the combination of Ivy+Kepler/7000 will be great for those who want a small laptop and great performance/battery life. That is why I decided to wait a little bit since architecture shrink is not updated every year.

 

Sandy bridge causing overheating for some laptops?
Not likely.
If anything, the temps have been more than reasonable.

Unless you need the enhanced integrated Intel gpu, waiting for IB isn't really necessary.
Even the upcoming discrete gpu lineup from both AMD and Nvidia will be simple re-badges (and die shrinks were skipped if I'm not mistaken).

As for the HDD... you could buy the 7200rpm separately and sell the slower one you get with the laptop.
Just a thought.

 

Every time new processors come out everyone talks about how much better they are going to be with heat and battery life but it never pans out. The current ones are always too hot and the new runs will run much cooler and run longer on batteries.

Another thing is that in the future you should be able to upgrade your SB CPU to IB if you really want to.

 

The quick sync is suppose to be around 50% faster. CPU performance clock for clock is everything from 7% to 29%. The IGP is vastly better but only matters when you have GPU switching like Optimus or the AMD stuff. 35W Quads are not mentioned anywhere and will probably not be released when the first CPUs roll out from their factory. But they promised us so it will come. Perhaps the greater IGP took an unwanted amount of TDP than what they expected?

So yeah, if you have plans to buy a laptop with GPU switching, you`d be a fool to buy Sandy Bridge now imo.

 

That's false, just the lower midrange cards are "re-badges" of the slightly higher last generation cards. The HD 7970 is new 28nm and 2048 sp. The mobile version, HD 7970m will be a re-badged HD 7870 which has 1536 sp like the HD 6970, but 28nm instead of 40nm.

 

Lmao what are you intel's ? 7-29%... where do you get that from. You made it up because IB is the same architecture as SB. The improvements will net <5% in virtually everything you do, often there will be zero performance gain. The only true upgrade is the built in GPU but anyone who relies on that isnt gaming or doing any sort of video work on the notebook, it's useful in a very low budget build, that's all.

Also, in less than two years you will look back at Ivy Bridge in between Sandy Bridge and Haswell, just like Westmere between Nehalem and Sandy now. Does Westmere really look so much better than Nehalem when comparing quadcore to quadcore? Nope, and nobody cares now because there is something better with real performance gains.

 

Whopsy. Was looking at the slides wrong. Didnt see 400 MHz faster clock for the ivy bridge CPU for some slides.

But look at this slide: Exact same clock frequence. Average of 11% better performance.
Intel Ivy Bridge i5-3550 vs. Sandy Bridge performance - Intel?s Official Ivy Bridge Benchmark Slides Leaked - Softpedia

Look at this slide: 56% better quick sync performance. And yes it is a CPU intensive task.
Intel Ivy Bridge 3770 vs. Sandy Bridge GPU performance - Intel?s Official Ivy Bridge Benchmark Slides Leaked - Softpedia

All of this means better performance than 5%. Just because it is the same architecture doesn`t mean they found a way to squeeze more performance out of it. Ivy have Tri gate too. Who knows what it will bring

 

You cannot upgrade your SB CPU to IB in mobile platforms. This was confirmed and discussed a while ago. Some desktop motherboards will be able to if it met certain criteria and gets the proper BIOS update. But mobile machines will not be able to.

 

I want Ivy

 

with regards to quicksync, is there even a program out that uses this technology?



edit:
i think the new power director 10 uses it.

 

Huh?
All video software that involves decoding and transcoding use quick sync. Or rather, the CPU use quick sync to do the job much faster.

I don't think so, the program has to specifically support quick sync afaik

In the end it all depends on whether the buyer is willing to wait or not, if you really need a laptop now then just get the Sandy Bridge notebooks, they're not bad notebooks by any means and should serve well for the next couple of years. If you're not in a hurry then by all means wait until Ivy Bridge comes out, as well as the upgraded CPU and GPU's Intel will finally include USB 3.0 integration and Thunderbolt which I find is a far more significant update for the mobile platform.

 

A typical (and predictable) marketing strategy designed to maintain a steady income stream. A minor technological advancement at best.

These are true necessities since they will take you into the next generation of peripheral integration in computing.

 

just curious, do we all know that no matter how big debates will be in this thread still all reviewers will tell that thiese CPus are "much faster" and all we will want to have on of that instead of what snb we already have

 

current notebooks already support usb 3.0 and Thunderbolt isn't exactly something worth rushing to. Unless you own a thunderbolt display..? pretty much useless.

 

disagree, I would actually want an ivy ultrabook, it aint going to be faster than what I have, it would actually be slower, but by a more tolerable amount.

Add to that that I would have finally USB 3 on macs, and there would be available egpu thunderbolt powered solutions

And that I would actually travel more lightly since Im out from 6am to 12pm everyday and with my mbp 13 all the time, my shoulders will say thank you

Thus leading me to the choice of either waiting for haswell or going for ivy, the problem is, if this was a 2008 or 09 mbp I would go without a second thought, however I just bought this in july

 

Not to sure mate, sure people have said many thing but it is still possible the mobile chipsets could work in the end.

 

true, my point was that it is better to look at these new technologies rather than the incremental bump in a few mhz as to whether waiting for an upgrade is worth it or not.

 

From everything I've read Ivy Bridge will be backwards compatible with Sandy Bridge, but not necessarily vice versa.

This is older news but don't see anything recently to dispute it:

Ivy Bridge’s Backwards Compatibility Explained

" According to an article over at the Chinese hardware site, My Drivers, both a firmware and BIOS update will be required in order to ensure that your motherboard will be able to use a new Ivy Bridge CPU. Unfortunately, only the H61, H67, P67 and Z68 chipsets will be “Ivy Bridge-upgradable” with the Q65, Q67 and B65 chipsets being left behind (UPDATE: HM67, HM65, UM67, QS67, QM67 chipsets are also reportedly excluded from the update). However, it is important to note that, according to My Drivers, your motherboard must be equipped with the ME8 (management engine) firmware, which cannot be upgrade by the user. We are a little unclear on this requirement, but we suspect it has to do with Intel’s Active Management Technology and that most boards are already equipped."

 

OP should next time post in What Notebook Should I Buy. This thread has long been beat up (and more to come) from IB vs SB dicussion.
