The GPU! Same old story..... car salesman tactics. You want a half decent GPU? well we will make sure you dont have that option unless you want to buy more memory,bigger hard drive and faster CPU. Only then will we even option a half decent GPU.
God I hate that crap apple has played for so long. You want even the option for the superior 4850? You must buy everything else first.
Integrated graphics are still just crippling the whole sytem in a effort to get you to buy more. Crippling sucks! All Buyers beware of the integrated graphics period. How long must we play this game?
edit : writing this on the 2.4 imac with 2600pro. Apple got rid of that one quick. 2 years later the 20" is handicapped with a.......9400M...here we go again.
I could just cut and paste my earlier thread, but I will just try to keep it to a comparison of just the two cards.
Well, the whole 9400M G is useless debate is just that, useless. And overblown. Need a better card, get a better computer with a better card. Problem solved.
More power brings more heat. Until the nM process dips well below .4nM you will have heat issues. The 9400M G has a relatively low heat profile, compared to a discrete solution. The 4670 in the 21.5 imacs are having heat issues, the 9400M G is not. Having said that yes I would like a better card too. But the 9400M G not as bad as people make it out to be. Such as yourself.
Depending on what you are using your computer for, gaming, video, etc. will dictate what GPU you are going to pick as well as financial issues.
If you're editing video, and watching video, the 9400M G is more than enough for your needs. A Blu-Ray player cannot come close to the processing power of the 9400M G, not even close and they play Blu-Ray fine.
Having more graphical processing power does not equate to better video performance, better video processing does. And the 9400M G excels at video with a dedicated video processor. Most intergrated solutions do not have this feature as well as some discrete cards. If you need video, the 9400M G will do just fine.
High end gaming no. If you do high end gaming, pick another computer or another card.
The 2600Pro HD is maybe slightly better graphically, actually the 9400 is almost on par with the 2600 graphically.The 9400M G supports Open CL, which is a advantage over the 2600. Cinebench scores are better as well, can you say better "video processing". Notice the 2600Pro HD does better on the older 3D mark tests, while the 9400M G does better in Cinebench, which in my opinion is a better mark of the processing power of the GPU.
The ATI card is listed 78 and the 9400 is listed at 108.
Check both of them.
And check these settings at the top of the page:
F.E.A.R. avg.(fps) | Doom 3 avg. (fps) | Cinebench R10 OpenGL | 3DMark Vantage ( GPU Score) | Crysis (fps)
Than Choose the :restrict: button.
What you will end up with is just the two cards compared with the various settings above.
Notice the Cinebench scores. As well as Game frame rates in various settings. Interesting.
