Why is there no quad option for the 21?

me might see the Dual Core i5 in 21" (even the dual core will be fast in the next iteration because of DMI)
Quad core i5 is mainstream CPU , not sure what apple will do for the next release say may/jun 2010

probably too small to shove a quad chip in it. Then again Apple only likes having those options on high end models.
What will most likely happen is apple will use the Clarksfield for these come next upgrade.
Popular speculation for these past iMacs that were just recently released was the idea of them getting Clarksfield-- but lo' and behold they got the desktop grade lynnfield line up of cpus.

It's the reason Apple made the new ones 27"...more room for more heat. 21" and apparently I would guess even 24" was just not enough room for them to have a current quad core processor in.
I think you're right first time. As for the heat issue, I thought the quad-cores were supposed to be more power efficient and run cooler than dual-core machines.
Are people suggesting that the dual-core machines run cooler and more efficiently than the high-end quad-core processors? If that's the case I might seriously consider getting a dual-core machine...
The greater question, to myself, triggered by your answers is:
When might we see the quads in Apple's laptop line? If this is a heat issue, as suggested, and a 21 iMac can't handle the heat? How is a 13 Macbook Pro going to by early 2010?
The 27" are using Desktop Chips. They have a higher TDP which causes them to run hotter.
Threads here imply Apple is waiting for Arrandale (a low power usage notebook version of i5/7) before putting them in mbp's.
If there is ever a quad in the 21.5" it won't be the desktop version. As to fitting them in a mbp, the notebook version does not compare to the TDP of the desktop version. Arrandale notebook chips use at most 35W TDP. The chips in 27" imacs are 95W TDP.
I'm no expert on this so any technical misdescription etc..... whatever.. but hope it helps
Very much so. I'm not ashamed to admit I know very little about this stuff. It's why I asked the questions I did. Many thanks for the info.
and future core i5s are 32nm so that should help heat.
the current Core i5 750 is 45nm
I think the 3.33 GHz C2D option with a 1333 MHz FSB is a desktop cpu...could be wrong.
nope they are standard desktop CPUs E7600 and E8600
actually for normal usage all the new iMac models are pretty fast (may be low end integrated graphics) and u can up the memory to 8GB easily
with upcoming Core i5 Dual Core, 32nm, DMI will fast when imacs are upgraded next time in 6 to 8 months
Couldn't they just make it a bit fatter? I don't think people really care about the width for desktops do they? Oh well, I have a feeling we will see quads in the 21.5" in about a years time.
The dual-core doesn't produce less heat when it does the same amount of work as a quad-core. The difference is that the quad-core can do twice as much work in the same time, and will produce more heat when it does that.
