Thanks to Tom Dahl, a member of this forum, I have some 4850 X-Plane benchmark results (vs other GPUs) to share....
Running X-Plane Demo 9.22 benchmark using a recorded 1 min flight of the X-15 dropped from a bomber, it produces results for three phases. Averaging these, we get....
iMac with GeForce 8800 GS = 70 fps
iMac with GeForce 130 GT = 71 fps
iMac with Radeon HD 4850 = 101 fps
Here's how the 2009 Mac Pro with various GPUs compares:
GeForce 120 GT = 43 fps
GeForce 8800 GT = 42 fps
Radeon HD 3870 = 154 fps
Radeon HD 4870 = 154 fps
It appears from the Mac Pro numbers that X-Plane "favors" ATI GPUs so don't draw too much from this. Hopefully we'll have results for a whole spectrum of graphics apps to share soon.

That's nice but it would keep the clutter to a minimum if we would keep responses in this thread for Radeon 4850 Benchmarks Only.
Thanks.
We have an iMac 3.06 with Radeon 4850 on order but it hasn't arrived as of today.
I've been awaiting Barefeats' test of the iMac 4850 with great anticipation. Hopefully you'll get your machine soon so you can test it before mine ships.![]()
The Mac Pro benchmarks are interesting to me because our readers on BareFeats.com want to see comparison of the Mac Pros with new iMacs. We have an iMac 3.06 with Radeon 4850 on order but it hasn't arrived as of today.
Tom Dahl, a member of this forum, was kind enough to run X-Plane at our request. We posted those results along with competing Macs on this forum.
If any of you want to run more gaming benchmarks on either an iMac with Radeon 4850 or any other iMac model that might be compared to it, we'd love to share our test procedures and test files with you.
If you have any of the following Mac games and are want to run benchmarks on your iMac, send me a private message:
Call of Duty 4
Enemy Territory: Quake Wars
Halo
Prey
Quake 4
Doom 3
Unreal Tournament 2004
World of Warcraft
How will this thread be possible if the 4850 iMacs are freezing their a$$es off?
ok, not a normal benchmark, but some people might like :
Counter Strike: Source on Crossover 7.2
Video stress test
1920x1200
Model detail : High
Texture detail: High
Shadows : high
AA : None
Full
163.51 FPS.
Also TF2, smooth as butter
Finally, Civ4 Warlords, full res+details, works like a treat - no slow down.

...from d510r said:2xAA, High settings, 1280x1024
30fps under normal play
35fps if you're looking out at detailed scenery
25fps during crazy explosions, multiple North Koreans
Add about 4-5 for removing 2xAA
Add about 5-10 for dropping to medium detail.
Rather unscientific tests but if you let it choose optimal settings which are the top figures it runs nicely.
I've recorded some video if you would like me to post a youtube clip.
Thats disappointing for a $22xx machine, hope they release new "drivers" to fix freezes and increase performance
Just finished playing a couple of hours of Left 4 dead in Windows XP via boot camp 1920x1200 all high settings very high shaders, anisotropic 16x and it maintains really high frames. Even when the action gets high and you have dozens of zombies coming at you the 4850 iMac never drops frames.
Thanks for the impressions. What, in your opinion, is "high frames"? Are we talking constantly 30+, constantly 60+ or something ridiculous like a constant 100+ fps?
Thanks!
