I would like to know this as well...
Would you need 256MB of video RAM for smooth 1080p like the Microsoft WMV-HD page recommends?
The Napa chipset does support 4 GiB of RAM.epepper9 said:
Once 2 GiB SO-DIMMs are available, it should be possible to upgrade.
Intel Imac
Just ordered the new intel imac with 2 gigs and 256 memory on ati. I have been waiting for a year to buy something like this. The part that I'm most impressed about is the support of an external monitor. I recieved confirmation that should ship January 18th and most likely arrive the 23rd. I realize the speed with not be there as jobs claimed but the fact that i can run supposedly two operating systems is a gem! ! !

Added a note to the iMac Guide
I just added a note saying that the 20' can have 256 MB VRAM as an OPTION, because I thought it was not clear enough ...

I'm slightly annoyed that the 256MB video upgrade is only availible on the 20' imac.

Unix and unix like OS's have a flat memory adress space of 4gb. Noramlly up to HALF this space is reserved for kernel functions and therefore it's unlikley that INTEL rev.A MacBooks and iMac's will support a full 4gb of ram. Maybe 3gb at the most.
Personally I'd wait and see Barefeat's performance tests. I don't buy into the hype that the Intel chip is twice as fast as the G5 as the same MHZ.

Ah, are you forget the simple fact that they never, ever, not even by selling every soul in Apple to the devil, were going to get a 970MP (or any G5) into an iMac or notebook form-factor?
Yes, clock-for-clock the Core Duo and G5 are probably very similar. But, that's not the point anymore. Pure performance, while important, isn't the key benchmark anymore. It is performance-per-watt. With lower power consumption comes better designed computers, which is Apple's main goal--To build the best computers in the world. Not neccessairly the fastest--the best.
If they can be the fastest too, we'll take it.

i heard that rumor too on abc
the imac, as it was released yesterday, makes me happy enough anyway and it stands alone as a great product, plasma or no plasma
how to get a free modem from Apple
If you go to this page it seems to say that you don't need a stinking modem in your new macbook or imac http://www.apple.com/macosx/features/faxing/
I called up Apple tech support and they just didn't understand this at all. So, they are sending me a free modem, haha... what a crazy thing. The sadest thing is that I emailed Apple 3 times and even called up tech support a month ago with my isight and told a genius at the Apple store. They just won't change that page??? Makes no sense... are they building in efax or jfax support? Yes, some ISP's may allow faxing through your cable modem but I think Apple better fix that page or a lot of people are going to get free modems, or worse yet another lawsuit.

There really doesn't seem to be much excitement about the iMac.
Not many pages here compared to the Powerbook (sorry Mac Book Pro).
iMac seems like a great machine, and it even has min-DVI now, which allows you to output to DVI like up to a 23 inch cinema display. That could be handy.
I'm probably going to order oen.

That is really dumb. All they need to do is remove the "or hardware" and they are set. At the bottom of the page they need to specify that the software is compatible with any Apple brand modem or USB modems conforming to blah blah specification.

Wow what a good deal, you get to mess around with Intel for 6 months for 999, then you get a brand-spankin new iMac Core Duo!
powerbook911 said:
there has been so much speculation about the intel, low voltage processor...which they have all become one way or another, compared to the g4, that we got what we speculated about for months
the imac is a better deal, dollar for dollar, if you don't have to be mobile and i suspect it will sell very well
The PPC 970MP is simply too hot for an iMac, just as it is too hot for a PowerBook. The fact that the Intel Duo Core is in the new notebooks is witness to its lower heat production. Per clock cycle, the Intel Duo Core is estimated to be a bit faster than the PPC 970MP for most operations, but slower for anything that was optimized for AltiVec. The benchmarks compare the dual core processor of the new iMacs with the single core processor of the old ones, because that was the only chip that realistically could be put into the previous iMacs.nomacyet said:
The bus speed has decreased from 700 to 667 MHz. That is in no way comparable to the bus speeds of the G4 Macs.
The jury is still out on whether the 2 GB RAM limit is a hard ceiling or is simply due to a lack of currently available 2 GB SODIMMs.

The address space limitation is not present in 64-bit Operating Systems (like WinXP X64). It is one of the main advantages of 64 bit computing.
Thus, I would assume that in the near future this limitation will not be present, as support for 64-bit grows.

Now you Apple allows you to hook up one more display as big as the 23 inch, so go for it!
runninmac said:
Exactly - this seems to be one of the features which some people are overlooking. External display suport is huge.
runninmac said:
The limit for the external monitor can't be the size right (23 inch ie.)?
I just read that stated twice now in this thread... Isn't the only limit the 1920x1200 resolution?
I want to hook the new iMac up to my Plasma in 1024x768 through the mini-DVI output, that's why I'm asking.
Another question. Can you run independent resolutions on your iMac display and the external monitor at the same time?
I have a question, for you guys.
I could connect my DVI 20-inch Apple Cinema, to an iMac. This is great news.
However, could I "turn off" the iMac display to have all the video memory go to my cinema display?
Then, instead of buying the 20-inch iMac and having to sell my ACD, I could just hide-away a 17-inch iMac, and use my 20-inch ACD. What do you guys think? Would this be possible?
Turn off the imac's display and have all video memory go to the external 20-inch ACD?

You are confusing a few things here: Logical address space available to one process, virtual address space available to the operating system, and addressable RAM.
The G4 processor supports up to 4 GB logical address space per process in theory, less in practice, for example 3 GB. The virtual address space is 2^52 bytes (4 million gigabytes), so the processor could in theory run one million processes of that size; your swap file wouldn't quite make it because your harddisk is too small. But you can run two or three apps, each using 2.5 GB of virtual memory, on a G4, and it will work; it will just be very slow. The G4 can address 64 GB of RAM. Not 4 GB, but 64 GB. Apple never built any G4 computers that would accept more than 4 GB, but the processor does actually support 64 GB of memory. (The G5 supports up to 4096 GB of RAM, which might become relevant ten years from now).
