Not me. I bought the 24" iMac before the new ones with the cheaper screens came out.
Is it not? Is the Core 2 Extreme not overclocked? I was under the impression from other posts that it was OC'd to the 2.8 speed.
So does this beef up the gaming performance or what? Compared to the 2,4 Merom? It seems like the 24" resolution is a lot to handle for a Radeon 2600, especially in gams like Prey.
Let's not get into that discussion here.
There are many threads already discussing the abilities of the new GPU in the iMac and pretty much all of them are quite intense and heated discussions! Just do a search and you'll find quite a few threads related to the new iMacs and gaming.This Apple page has a link to the Intel Core 2 Mobile Extreme Product Brief
Unless I am reading this wrong, the brief mentions only a X7800 chip.
"... Performance measured on Intel® Core2 Extreme mobile processor X7800 running SPECint*_base2006..."
What's the deal?

Yes, but when the iMac launched, the X7900 entry didn't exist on that page. Believe me, I Googled far and wide to find a 2.8GHz Core2 Duo Extreme mobile chip and came up with nada. All I found was articles on the X7800 being FSB-multiplier unlocked and OEMs selling them at 3GHz plus.
I know a few folks gutted the iMac when it came out. Did anyone gut a 2.8GHz model and if so, did any of the pics show the processor top with the part number and stepping info? Easiest way to know for sure.

The Core2 Extreme Edition mobile CPU is FSB-multiplier-unlocked, so you can overclock it without having to raise the FSB speed. You can just raise the multiplier from the stock setting.

However, now, the X7800 doesn't exist on that page. AND, that's the page the Apple article will lead you to. So, I believe Apple was using the X7900 all along, it just wasn't published yet.
So there are two mobile Core 2 Extremes out now:
the x7800 which is 2.6Ghz standard but has been overclocked to 3.0ghz by some companies, and some argue this is what was clocked at 2.8ghz in the new iMac;
then there is the x7900 which is 2.8Ghz stock and was just announced? Some argue it is what is in the new iMac. If it is, meaning Apple got them early, then the iMac is NOT overclocked, though it has an overclockable cpu.
Is this correct? and is this where some of the confusion is coming from? People getting the 2 C2E models mixed up? I hope this helps straiten it out. Someone who knows more could elaborate to clear things up.
Thanks for the link.
It could also be confusing because the title:
Intel Launches Mobile Extreme CPU (Already in iMac)
Do we have any proof these x7900s (which the article is about) are indeed those in the high-end iMacs, and not x7800s? Or are people just conjecturing both possibilities with no proof?

No offense to Rocketman, but am I the only one who has no idea what any of this says? Maybe I'm just slow today

You could just take yours apart when it arrives and settle it for us all, once and for all.

Leave it to Eidorian to be on the ball with the Penryn stuff.
Thanks for the link and clarification.

800mhz fsb?
I thought I saw that the iMac only has a 667FSB... guess the extra speed goes to waste or did I miss read something? Also, why have a great computer with such a lame video card? I had my visa all warmed up, but looks like I'll keep my current core duo for a while yet.....

800MHz FSB, 667MHz memory bus. Video card is the best mobile card available from the current generation. What card where you looking for?

No. It's OCable beyond 2.8Ghz. It just won't be doing so in an iMac or anything else which has poor thermal management for the sake of needing to be extra-quiet (or has poor thermal management and needs to be extra-quiet), as someone has put the computer right in front of your ears.
The rationale for using it and why it's used stock when no-one else who will use this CPU will use it as such is easy to see. The machine is crippled as a desktop as it uses laptop componentry, so to play catch-up they use a faster processor. But driving the faster CPU to anywhere near it's maximum potential will mean major heat issues for the thin case. So it's kind of trade-off.
They're using a fast laptop CPU so that it's not completely outpaced by a $700 E6750/1333FSB/DDR800 desktop using desktop parts, but they're idling it so that the heat doesn't overwhelm the rest of the components.
I like the styling of the new iMac, but if any single Apple product truly defines form over everything else, the BTO iMac is probably it.
Yes. Look for it in gaming laptops soon. X7800 laptops are just around the corner.
I'll believe that when I see it. Do you have any evidence that this has happened in the past? Remember we are talking normal usage here, not some small niche offering.
The X (Extreme) CPU's are for gaming and high-performance use. They're delivered with unlocked multipliers specifically for overclocking use. It's not a 'normal' use. Apple's use for it is pretty special for the reason I stated. They need the processor so that it isn't a complete dog when compared with 24"-equipped E6750 desktops nearly half the price, but they can't actually run the CPU at it's full potential.
As for previous evidence, the unlocked-multiplier 2.3Ghz C2D option in my Dell M1710 laptop means I can run the 2.3Ghz processor completely reliably at just over 2.8Ghz without any significant increase in fan activity (and unlike Apple PC's the Dell has a properly designed cooling system which balances noise and heat removal better). The next-gen machine is due to turn up any day now with the 2.6Ghz X7800, which should be good for 3.2 ~ 3.4Ghz in the laptop.
