Forget Arrandale, SB Huron River Platform on the Way

Heterodyne whine is more of an internal power supply problem than a cpu problem......

 

All these sites saying SB will launch early are wrong: Link

 

Which would help to prevent any shortages, and thus increased prices and wait times, thank goodness.

 

Well I've decided now. I'm going to upgrade my desktop for now and then wait for a Sandy Bridge laptop until late 2011. Not a bad trade off. I'm getting a free Dell studio xps 14 anyways.

Anyone else gonna wait with me until 2011? There's no point of getting a laptop when SB is around the corner.

 

i'm here witcha! only half a year left!

 

i can't be bothered waiting.. i'm getting a G73 now and then upgrade CPU later on when sandy bridge comes out...

 

will the sandy bridge cpus be compatible with the pm55 chipset?

 

Not at all. Buying a notebook now means you are stuck with Nehalem. Buying a Sandy Bridge laptop though means you are set for the next two generations as Sandy Bridge laptops will be upgradeable to a 22nm Ivy Bridge cpu.

 

are you really sure that 32nm sandy socket will support 22nm ivy socket and the 22nm after that from where you got that info?

 

I read it somewhere, will try and find the source but also think about it. Intel releases a new generation and then shrinks it before introducing the next generation. You have always been able to upgrade a laptop bought at the beginning of a generation because with shrinks Intel does not change the socket. For example:

65nm Core Duo (T2300, T2400) to 65nm Core 2 Duo (T5600, T7200)
45nm Core 2 Duo (T8100, T8300) to 45nm Core 2 Duo (P8400, T9400)
45nm Nehalem (cancelled) to 32nm Nehalem (Core i3/i5/i7)
32nm Sandy Bridge to 22nm Ivy Bridge

Then after Ivy Bridge is the brand new 22nm Haswell were we start over again.

 

I seriously hope so for ur sake lol ... but a 920xm or 940xm will be great and super OCable.. and u'd get them cheap in 2-3 years anyways... these new CPU's are really for ppl who need more battery life.

 

i really am waiting for 32nm sandy bridge + 28nm ati mobility graphics (hopefully) as my 2yr old laptop with t7500+8600m gt g80 runs super hot and dying on me i will definately buy a new laptop in mid april 2011 still 9 months i hope my acer 7720g goes kaput on me during these 9 months

i also hope 32nm sandy bridge quads will have a tdp of 35w i dont like the clasfields quads because of their huge tdp and they run hot i want a cool laptop

32nm laptop duals are good but after i saw the intel presentation that said clock per clock sandy bridge is 20% to 30% faster than current arrandale i decided to wait because it was in june i decided to change my laptop

also currently i think i5 540m is a great processor intel has reached a level of perfection with it compared to i7 620m diff only 133 mhz and 333 mhz in TB but power consumption peak is 15w diff and runs hotter. I hope the upcoming i5 580m pulls that as well then i might skip sandy bridge

but also the dilemma is no upgrade options and i am pretty sure sandy bridge 2.4ghz will beat a upcoming i7 640m with stock clocks without TB

also Turbo boost for 1 core will start to become irrelevant after a year as more and more applications will use 2 or more cores even basic media players and browsers.

but for socket compatibiliy for ivy bridge 22nm i am not sure if that could happen then SB is totally worth the wait

but see this

late 2006 to 2007 65nm procs had pm965/gm 965 9 (merom)
2008 to 2009 only 45nm with 800fsb supports 965 series
the 1066 supports gm45 (penryn)

2010 arrandale (hm55/pm55)

from 2010 onwards intel announced a new socket for 2011 for SB so they might change every year or they might under scrutiny if current users of arrandale cant upgrade to SB so they might reconsider SB mobo and make it to support IVY bridge mobo 2012

 

Hi Riddhy,

Notebookcheck has the 620m and 540m both at 35TDP. Are their figures wrong? I'm wanting low power usage and you're saying 540m is the way to go over the 620m, just wanted to confirm?

Cheers

 

They produced a full review of the whole Arrandale lineup a while ago that showed the i7-620M's power consumption was skyrocketting compared to the lower i5, but they corrected this later (at least on notebookcheck.de), it appears their results for the i7 were messed up. So yeah the i7-620M is a great dual CPU but it's expensive.

Sorry but Sandy Bridge mobile quad are supposed to be 45W TDP if I remember right. But still there should be a lot of optimization on power consumption.

For sockets I would bet on sandy bridge sockets remaining compatible with ivy bridge. Either way if ivy bridge is the same kind of die shrink that Westmere was to Nehalem it will deserve a big lol. As for 28nm ATI I'm afraid it won't be there for SB release but rather H2 2011.

 

no the sandy bridge is expected to have a TDP of 35w and the naming scheme will remain the same as i3 i5 i7.
go to this website: First Intel Sandy Bridge processor specs slip out | Electronista

 

I think the link you provided is about desktop parts, and the 35W TDP seems to be pure speculation but it sure sounds incredible for a desktop CPU. If by chance it happened to be aiming right I guess it would be correct for the lowest clocked dual i3 but certainly not for quad core CPUs.

 

Yup those are desktop. I really think we can get notebook quads at 35W and full voltage dual cores under 25W.

 

Agreed. I have certainly heard the whine in various Core 2 notebooks, but I found that the problem was particularly apparent in the Pentium M series. I had a Dell Inspiron 9300, and the whine was nearly unbearable in a quiet environment. I have heard that the problem also exists with Arrandale, and I have also heard that Intel chooses to ignore the issue, since they claim they are unable to hear this so-called CPU whine.

At least for my current computer, either the situation has improved, or my hearing has deteriorated, such that I no longer hear the whine, unless I press my ear against the surface of the notebook. I think this more likely is a result of the Balanced power profile reducing the frequency of clock stepping operations, which for my Pentium M 760, was much more frequent, and so the whine became much more apparent.

Edit: I have no idea where I quoted from. I had presumed I was on the last page when I navigated to this thread. Apparently not.

 

ULV quads FTW

 

lol dream on FTW.. ULV quads will be a long way but can't wait for octacore

 

That might happen in 2012 with 22nm Ivy Bridge, that is when quad becomes mainstream.

 

Intel plans to deliberately limit Sandy Bridge overclocking | bit-tech.net

 

a lot of power users will be pissed at this

 

i'll be one too.. good think i'm sticking with arrandale and clarksfield..

 

Sucks, but we'll have to wait and see how big of a deal this will actually be in real life.

 

AMD Llano and Bobcat to have USB 3.0, not good if Sandy Bridge really doesn't.

 

but if u have e-SATA , why would u want USB 3.0? Unless u use external SSD , e-SATA is really more than enough..

 

eSATA can only be used on machines with eSATA ports. A USB 3.0 device is backwards compatible with previous USB specs, which is almost universal on all computers.

eSATA requires a separate power connection. Low-power USB devices can get power over the USB connection. This means that you only need 1 cable for 2.5" external USB drives.

eSATA has a maximum cable length of 6 feet. USB spec allows much longer cable runs.

It's not always about transfer speeds.

 

If I'm not mistaken, you have to boot with the eSATA device connected, you just can't connect it while the machine is running.

When I found that out it kind of took the wind out of my eSATA sails...guess it's not a huge issue but not exactly convenient.

 

To simply read/write data onto the eSATA connected HD, you do not need to have it connected before the computer boots up.

If that is required - get a new system; that is not normal behavior for eSATA drives.

 

...or you just need to change hdd bios settings to make it work properly

 

Another peek at Intel's coming year

( http://tech.sina.com.cn):

 

With Intel seemingly targeting Sandy Bridge for the mobile space, is it possible that the computing power gap between desktop and notebook CPUs is going to be smaller than ever before?

 

well not here.. like newsposter said , for e-SATA , u can just plug it whenever u want.. this isn't SATA like what ur describing, its e-SATA

 

The eSATA spec supports hot-swappability. However, it is up to the chipset / motherboard manufacturer to decide whether they want to support hot swappability in their drivers. So not all eSATA drives are hot-swappable in all systems.

USB, however, is universally hot-swappable.

 

No, the difference will still be substantial since the cooling capabilities of desktops will always be far better than notebooks, hence desktop CPUs can be clocked much faster than their notebook counterparts.

 

Link Sept 13-15th is IDF! Sandy Bridge and the new G3 SSD details will be revealed.


Link: Graphics can now receive a boost via Turbo Boost.

 

Intel's 'Sandy Bridge' to use new specialized silicon

 

i wonder when we will see software that actually supports this transcoding thing and avx

 

This sounds incredible. Do you guys think it would be possible to upgrade my current laptop with one of these new processors when they are released?

 

^ unfortunately not, because these new processors require a new motherboard with the upcoming 1155 socket

 

Damn... that sucks.

 

New computer technology typically isn't very upgradeable for long...

 

i guess each platform will only lasted a year before being bested with the new generation, that is very fast indeed.

 

Not a sure thing. Nehalem sockets on mobile parts could have lasted longer if they hadn't screwed laptop users like they did. The architecture was launched in September 2008, the first mobile parts were available a year later. And for the rest of the lineup we had to wait 6 months further, partly thanks to a nice shortage. Now Sandy Bridge mobile & desktop CPUs are launched simultaneously & the next planned upgrade on intel's side is a die-shrink in 1y that might maintain compatibility.

Plus Sandy might last quite long as intel plans the next step (22nm) to be possibly difficult, at some point even mentioning the possibility of breaking the tick-tock pattern, which means releasing another xxx-Bridge between Sandy and Ivy Bridge.

 

How do you know they screwed us? Intel said they cancelled the 45nm Nehalem laptops would have got in 08 due to the economy.

 

I overlooked this before, but I think it should be Gbs (gigabits), not GB (gigabytes).

 

Changed !

 

I hope llano is really competitive. That will ensure intel will be on its toes. Currently intel has zero competition on high end laptop market.

it does not look like bulldozer based APU's will release until 2013 at best. I think intel will have a free reign until then.

 

^ are you sure? i thought bulldozer will be released in 2011?
