The 9800GT is better because it has more shaders small vector processors within the GPU that figure out how 3-dimensional placing affects the lighting and color of what's on screen. You cannot change the GPU on the current iMacs. They are soldered onto the motherboard. Wait a bit longer, Apple should come out with iMacs with 8600M GTs' in them. Those cards are excellent for gaming. Not in the range of the 8800, but still more than enough.

9800 and 8800 series are ancient :rolleyes:
 
Yeah with that same logic, every mobility card could be considered a desktop card, and every desktop card could be considered a mobility card :)
 
Don't give examples that are not true, do your research and stop guessing that they MIGHT be the same chip.

I know mobility 4850 is based on desktop 4850 and has just lower clocks but if we are talking about future iMac, the mobility 5850 is not based on desktop 5850. ATI 4xxx series isn't that normal because most mobility GPUs are based on similarly named desktop chips but that's just one series.

What the **** dude....? So your saying the 9600gtm does *NOT* have half of the shader cores? Well your wong than. I know 1000X more about gpus than you do. Im not guessing about ****. I never said they were the same chip anyways. The only thing i said was that the mobile version had half the shader cores. If i wanted to be really specific and technical i would have.....damn. people never listen.

FYI I am talking about the current imac and not the future models.
 
You didn't know enough to think the current iMacs have mobile gpus :p

I never said that

Says a guy who said iMacs use desktop GPUs and desktop and mobile chips have exactly same specs :rolleyes:

I never said they were the same chip anyways.

Exactly same specs = same chip

FYI I am talking about the current imac and not the future models.

Why on earth did you mention 9600 then? It has never been used in iMac anyway...

Lawl. This post made my day. Argument fail.

OK i see the problem. Your getting a mix up than.... You need to read more carefully next time and comprehend it.... i probably could of reworded one of my posts tho to not cause confusion.

1. One member said that the gpus in the *current* imac were the mobility versions, which was technically wrong. He than showed my a picture of a gpu on a mobo... duh. "Although its not the exact physical size it has the exact same desktop specs and might possibly be underclocked to save heat problems." This was talking about why its technically not a mobile version. The 4850 in the imac is a desktop based gpu but of course its smaller. To save heat problems they underclocked it.

2.The 9600gt was an example of how mobility vs desktop versions are different. I ONLY said that they halved the shader cores going to the mobile version. Now you got this part the wrong way. The 4850 in the imac is the exact same chip. You thought i was talking about the 9600gt and the mobile version. (partly my fault.)

3. This part "Don't give examples that are not true, do your research and stop guessing that they MIGHT be the same chip. " well, i just dont get that or where it came from.

4. I hope this cleared up the problems.
 
Oh good god all mighty, how old are you? 14?

Firstly, all iMacs have mobility gpus in them. This has been discussed over and over on the forums...if you want proof then take the time to search yourself because I'm not going to do the work for you.

Secondly, the mobility 4850 (used in the top end 27 inch iMac) is unusual in the fact that is actually the exact same chip as the desktop 4850, just underclocked to use less power.

Got it now?

Nothing to do with us not reading the garble that you are posting, just open yor eyes and accept what some other people are saying.

i also hope a gt 320m is provided for the base model + upgrade the a gt 330m 512mb i hate 256mb video cards.

That presumes that they keep the C2D processors on the entry models. If Intel drops the prices on the i5 (or intro other versions can use) then Apple can dump the C2D from the iMac. One reason they didn't use C2D last fall was that Intel wasn't ready for high volume models ( the i5 and i7 models shipped later in lower numbers). At this point they have caught up.

If intel drops prices on Lynnfield i5's could use them which would make iMacs quad across the line. That would be nice. Or Apple can use Clarkdale ( Dual core i5 with embedded Intel IGP ) and spin them as "greener" iMacs. They go into reduced graphics mode when not doing much and turn the discrete GPU off. Sure you are plugged into the wall, but you have to pay for the electricity. :) [ that's the only 'hook' that Nvidia has is that auto switch stuff Apple has cobbled together for their set up. ]


On the desktop iMacs there is little reason now to stick with C2D. It isn't like there is a physical space constraint blocking them. Price wise there are i5s that are just as inexpensive as those 3+GHz C2Ds were last September. Also would be better if all iMacs were using the same exact processor socket 1156 that the Core-i desktops use. That means can use basically the same mainboard with different parts plugged in.

Nvidia could get dumped across the board for the iMacs which only makes the parts more uniform across the line up. Get a line up with higher OpenGL compliance and if go 55xx-57xx HD on GPUs
 
Mobility 4850 has specs as desktop 4850, because they're both based on the same chip-- but you know this already. The mobility 4850 is underclocked and has a downsize motherboard. The real "technicality" to the whole point is that ATI markets the card under the name mobile 4850, and the card is meant for laptops and smaller computers. With the same logic of comparable stats, one could say if apple puts mobile 5850 in the next iMac, they're putting in desktop 5750. You could get away with saying any mobile card is a desktop card by the same logic, as one way or another they're all based on certain chips.
 
Honestly, I hope they do a complete rework so they use desktop GPUs instead of mobile ones. I also hope they start using desktop RAM and not laptop RAM.

I'm betting they'll use a 5850/70m or something better...

Wow you must be 14. Read the post again dude. I said that the cards are mobility but TECHNICALLY they are not because of being based on the exact same desktop chip. I also said that it was underclocked... to use less power.............. Dont start trolling
 
I do not think there's a difference between the 200 pin so-dimm memory the iMacs use and desktop dimms, besides the size.

don't condescend people because they don't understand your posts and their lack of clarity. it makes you look like an idiot.

TECHNICALLY, they ARE mobile cards. they just happen to be based off the desktop chip.

Technically speaking desktop and mobile cards are just names, they are all based on same chips. iMac uses mobile GPUs because the GPUs match the specifications of the mobile GPUs, not the desktop ones. By talking about desktop GPUs you just confuse people, a lot. Moblility 5850 is closer to desktop 4830 than 4850 as they are all based on RV770 chip.

Why did you mention 9600 then? It had nothing to do with ATI 48xx other than that it showed that most mobility chips are NOT based on desktop counterparts.
 
Faster DDR3 in the current iMac wouldn't help anyway. A current quad-core i5 or i7 can't fill the total memory bandwidth dual channel PC8500 DDR3 has to offer anyway.
That's one of the reasons Intel stepped back from triple to dual channel when they made the consumer i5 and i7. It's only useful for the newer 6+ Core i7's, and still only by a little margin.

Besides that, I'm also in the market for a new iMac, so I'm patiently waiting for Apple to update the GPU's, because I'd love to do some gaming on it. :)
I wouldn't expect them to use desktop GPU's though, because that would force them to leave the current form factor, or a similar sized one. And the chances of that happening are slim to none...
 
for ati, will they ever modify stream to make a stream processor as good as one CUDA CORE? seriously. 320 SP vs 16*3 CC is sad.

All i was saying is the 4850 is technically a desktop based card, just because of the same chip. The 9600 was a comparison showing the differences between the mobile and desktop counterpart and how it normally is; the 4850 does NOT have any differences, besides the underclocked part which is why its a bit different.

All you did was start an argument with capital letters, insults, and swear words. People may never take your opinion here seriously again. Enjoy! :D
