Why isnt there Quad Core notebook processors?

Other than those heavy desktop replacement notebooks, which use desktop CPUs, why hasnt most other notebook manufacturers adopted Quad core processors? I guess it leads back to asking, why hasnt intel made Quad core processors available for mobile CPUs?

 

45W TDP 10char

 

Ummm, there are mobile Quad Cores, they're just more beefy in terms of power and heat output so you generally need a larger notebook(at least 15") to hold them.

 

In 2011 Intel will be releasing the 22nm shrink of Sandy Bridge codenamed Ivy Bridge. This is when quad cores will overtake dual cores as the standard option in Intel powered laptops (except netbooks and probably very cheap laptops). AMD in 2011 is coming out with Llano which will also be a quad core. So 2011 is the time when quad core becomes the standard.

For now they use too much power. You can't fit a quad core in an Acer 1810t and expect people to be happy. Come 2011, I'm sure Intel will have the TDP down to ulv levels and we can see some quad core culv notebooks!

 

The i7-720QM, i7-820QM, and i7-920XM are all quad cores. Going back a generation, the Q9000, Q9100, and QX9300 were all quad core processors as well. That has been it so far for official Intel mobile quads, though.

 

I doubt that...

 

I just put a Q9200 into my notebook, not an hour ago.

 

Doubt what? I never said quad cores would go in ulv machines right away, but as soon as they do I'll be buying.

 

... then in 2012 all cores will be modular integral motherboard units around a sqaure inch.
so will graphics cards.
and they'l all take only 5w each!
since were dreaming...

 

My money is on stream computing,we all know that with techs like openCL and Cuda that an windows or Linux OS will eventually be coded so those 160 .7ghz penta-cores of your G73's Ati 5870 can sing that beautiful song,at around 60w today,45w tomorrow with 32nm.

 

I might be repeating what I write on the "8 GB RAM" threads... does anyone need a quad-core ULV laptop? Sure, it would make for a nice showoff, but overkill, wouldn't you say?

 

Not necessarily, what if you want to completely disable your page file? With 8GB and a 64-bit OS, you can.

 

There are a few Windows programs I've run into that for whatever reason are stupid and they require a page file to exist. I would set it to 512MB or so, just in case some program requires it. It's less common any more, but if you ever run an old bad app, it's not a huge waste of disk space to keep that around.

 

You should post up some benchmarks somewhere.

 

What exactly are you looking for? I'll run whatever you want that I have access to.

 

I don't care, WPrime, Everest CPU tests, Fritz chess benchmark, whatever. Can you overclock with that system?

 

I admit, I skipped the Q9200 because it was never "officially" released.

 

and not to mention an illegal ES processor but ppl with the same laptop have pushed a QX9300 with FSB overclock to 3.0GHz ++ ... he should be able to do so till about 2.7-2.9 GHz...

 

The Q9200 is a sweet chip, I had one running in my M17x OC'ed at 2.66 24/7. I have recently sold it as I'm getting the R2 revision replacement M17x which uses mobile i7's. I sold my QAVR to RoyMathieu who also has an M860ETU, he is quite happy with it, it is a great budget chip and works as good as any retail chip.

 

I could OC, but only by the pin mod method, and that's not my thing.

 

Welcome to 2007. Remember when Santa Rosa failed to live up to expectations?

 

Quadcores still aren't mainstream, most users don't care enough to pay the higher price tag.

You can now overclock using SetFSB, up to an FSB of 1333MHz.

See this thread for more info:
M860TU and setFSB

 

Hmm interesting. I'm going to avoid it though, as my GPU is already overclocked, and my past experiences have shown me that it's a bad mix. 2.4Ghz is more than enough for me.

 

You're right, but if one can afford 8 GB, would storage be an issue?

(I'm unaware of any other reasons to do that. If that's the case, please don't mock me, share your knowledge ).

EDIT - oooo, so now I'm guru!

 

I wasn't referring to storage actually, i was thinking of more to reduce HDD access thrashing when you don't have enough RAM to store game textures, this happens in GTA 4 with me all the time. If every byte of commonly accessed files can be stored on RAM which is much faster than HDD SATA controllers, then overall your system will run faster and games will not stutter because they don't have to access the HDD storage, which is much slower, which in turn doesn't supply the GPU or CPU with enough data to process, which in turn results in stutter

 

My Q9200 was getting 17 seconds for WPrime 32m test and had me wondering... I downloaded the latest version and got 10.801.

 

Yep, good enough reason.

I've never played GTA4, always two years behind when it comes to games, and wrongly assumed there were no commonly used apps that could be resource-hungry enough to break the 4 GB barrier.

 

Well, not RAM deffinitely, but it absolutely gobbles up the page file. And if you can disable it, with 8GB and a 64-bit OS GTA 4 can feel free to eat up all the RAM it can find, then it will be stutter free.

 

You can also use SetFSB can't u or is ur PLL locked?

 

Yeah I just found out that I can indeed use SetFSB, but the M860 is too unstable when the GPU is also overclocked.

 

This is odd how come the Q9200 @ 2.4ghz gets 10.8 secs in Wprime while my Q9650 gets about 12secs OCed at 3.3ghz

Surely my score should be much lower

 

Which version of wPrime are you using? Did you run 2.01?

 

Ah no I was using V2.00 my best score was 12.03secs. I assume 2.01 improves scores dramatically then?

 

Post #26 says his score was lower with the latest version.

 

Here's mine :
