Nehalem Mobile processor delayed

Hello,


Does anyone know if the Nehalem Mobile processor has been delayed due to the Centrino 2 processor inventory stock? I am hearing that it will debut in Oct/Nov instead of July/August.

Thanks in advance for any replies!

sorry if this is the wrong type of subject/question for this forum

 

Yes, it's been delayed to October 2009 at the earliest. Expect it to show up in laptops available for shipment late-2009.

 

Blame the recession...

 

Awesome, for me at least. Very selfish, certainly, but this is a bittersweet comfort, how melancholic it is - to watch your laptop getting outdated with ones own eyes

Initial shipment is also likely to be extreme mobile CPU, if their roadmap's structure remains same.

 

I don't think it's just the recession - Mobile Nehalem is also projected to be quite hot (45W TDP). I'd suspect Intel prolly has issues with that, and it might also be hard to pitch this to OEMs who might not see benefits justifying such increased power requirements.

The problem is - software application development is not yet on the level where advantages of Nehalem would be too beneficial on a laptop... Remember, we're not talking about CAD/Rendering/Video Processing here...

So, if we are talking about 45W TDP - for your typical notebook, e.g. office, surfing, youtube, maybe some gaming - what do you benefit compared to a 25W P9600 ?!? Absolutely nothing... And, yet, this would probably mean less battery life unless battery gets bigger.

Remember that Intel managed to do a very nice Core 2 Duo succession from Napa/Santa Rosa to Montevina, mostly thanks to obvious benefits in TDP reduction with slightly increased performance. There are 25W Penryns running @2.5 GHz, while Meroms were @34W TDP at >1.8 GHz range. Also, clock-for-clock the Penryn was ~5-15% faster due to a cache and better radix divider... So, for less power you get more performance.

Now, with Nehalem for mobile - you might get more power, which most people won't find any purpose - and for quite steep increase in TDP... My opinion is, this is a bit displaced product.

I have i7 965 sitting in my home and a C2D notebook (Vaio Z) - most of the time I am working with the notebook docked @ docking station... Yes, i7 is a bit faster for desktop apps (and quite faster for video encoding) - but most of the time, I just don't need it.

This would mean that mobile Nehalem would initially be "destined" for extremely high-end notebooks and gaming mobile rigs... Not really a mass market, it cannot certainly finance the whole architecture.

 

Good point psyq321, from what I read, it comes in either 55w or 45w, the former is just too hot. Its more than twice the TDP, of say P9600, and I dont think neither Clarksfield nor Arrandale has Intel's new QuickPath Interconnect, but rather DMI.

I doubt that there will be 25W nehalem dual core initially, given the high end chip actually are hotter than the last gen. The major difference brought around by i7 is the QPI, and AFAIK that wont make it into mobile package, then what kind of performance gain will it bring? that is also forgetting how much premium desktop i7 set up cost compared to C2D/Q, its very likely initial nehalem mobile chips will be priced sky high.

Then its probably better to directly upgrade to Westmere, which will be cooler, and actually make real time difference with new instructions in encryption, etc. By then DDR3 will be far more affordable as well, better stuff is around the corner all the time, but is mobile Nehalem going to be better initially than much refined Core 2 line up?

Only the quad cores are coming this year, dual core is early next year. And only the quad cores have a 45w TDP, we don't know the TDP of dual cores yet.

 

It will probably be better, but at the cost of TDP. Core i7 has the same issue, but heat matters less in desktops so this is usually ignored. The initial mobile Nehalem won't really have much competition because it is quad core and the mobile C2Qs are either disappointing for anything that doesn't require 4 threads (Q9000) or absurdly expensive (QX9300). It may be hot, but it's powerful and its certainly cooler than stuffing a 130W desktop processor into a laptop a-la Clevo.

I have no intention of buying this, but it is nice to see quad-core processors moving to laptops and the delay is bad news. Also, keep in mind that even desktop Nehalem has tricks to keep power usage down which surpass those used by C2Ds and C2Qs. Unless you're actually using the processor, the battery drain may actually not be that bad.

 

The problem is, notebook designers have to deal with TDP when designing the notebook thermal management system...

As the market demands thinner and lighter notebooks, I don't think that TDP of 45W is the step into the right direction - for example, Sony Vaio Z is so lightweight that even the 35W C2Ds go into throttling often - putting the 44W X9100 and trying to load it full-speed @3 GHz leads to 105 degrees in just few seconds.

So, if they want to put a 45W part inside - they will have to re-enforce the thermal hardware... this is all nice and dandy in case of "performance" notebooks, but for "thin & light" this won't work...

It will be interesting to see the TDP of dual-core mobile Nehalems - if they could keep it around 25W they would be the same kind of success like Penryns - by applying the same formula: nice speedup with no extra power.

 

The quad core Nehalems aren't aimed at the type of person who buys a Sony Vaio Z -- that would be pretty silly. Those people will be content with C2Ds until the release of Westmere.

 

When gonna Dell introduce XPS M1830 with 280m SLI and nehalem ? I will love that.

 

TDP on the CPU side increased by 10W because the entire Northbridge moved to the CPU. Since Calpella systems have only two main chips(the Ibexpeak-M PCH and Nehalem CPU), power consumption is similar as the current generation products.

The 55W part is the quad core versions(45W + 10W) and the 45W are the regular dual cores(35W + 10W).

Nothing changed, please move on .

 

Blame AMD. If AMD was still breathing down their neck like in the P4 era this CPU would have been out since a long time...

 

Blame intel! there CPU's are so much better!

PS. AMD wasn't breathing down Intel's neck in the P4 era, AMD was to busy kicken' intel butt to breath down there necks...

 

rofl.

My laptop's chip is a 88watt, the chassis is built to accept 110watt chips.

 

Unlikely but ok. Intel took 2 years to ready Merom/Conroe/Woodcrest. But those CPUs are really Intel's response to the Athlon 64 back in late 2003, not the Athlon X2 in 2005.

I think its just IA64 that purposely hindered Intel's x86 venture. We don't know what would have happened on the Pentium II/III era if IA64 never existed.

Now I think after learning being beaten by AMD for 2 years, we are seeing Intel in full force.

 

In AMD's best time, they were still being outsold 2:1.

 

I read somewhere about the processor with gallium arsenide and it is under testing phase. According to its character, it gonna poweful and fast beyond imagination and HP is working with it.

 

Hafnium...gallium...what next?

 

Graphene. And finally unobtainium.

 

Unobtainium?
Never.

 

Roflinium!

 

There is some info about gallium arsenide.

Adamantium

 

I'd prefer Allmanium or Vaughnium.

 

what about aluminium lol

 

FAIL. lol...

 

Yeah really...that's spelled with just ONE "i"...LOL.

 

That article is from 1985.

 

Again, ROFLINIUM!

 

Ok then rudemanium...

 

Slightly going off topic?

 

Ummm
not slightly..but completely off topic...atleast we are giving the cpu developers a new name for their next generation.

 

Nextgeneratium
