ATI Radeon HD 4850 Preview: AMD Delivers Performance for the Masses

Crysis
With CrossFire, under Crysis, the 4850 does quite well. There's a bit of an odd scaling anomaly, but no matter how much we retested things it came out the same way. We've had discussions on the fact that the built-in test we used can end up bound by the fact that it moves so fast that it's got to move things on and off the graphics cards way more than normal. This might help explain why the relative performance of the 4850 CrossFire setup goes up at 2560x1600, as it may have plenty of power to process the scene but not the capability to handle the swapping in and out of so many complex objects (which wouldn't happen under nomral conditions in the game).
Call of Duty 4
4850 CrossFire simply ownz Call of Duty 4. Nuff said.
Enemy Territory: Quake Wars
Our Quake Wars benchmark shows a much different CrossFire scaling story, as it really just doesn't do much. The impressive highs we see with CrossFire are underscored by these inconsistencies in support.

I know this is a late reply but I will do it anyways. :)I am just going by what your testbed specs says...
------------------------------
Video Drivers
Catalyst
Catalyst 8.5
ForceWare 177.34 (for GT200)
ForceWare 175.16 (everything else)
------------------------------
If you used Beta drivers you probably should have updated that in the specs and whether they are based on 3.5 or 3.6. It would still be nice to see some results with the new official 3.6 driver though. :)

I meant to say 8.5 and 8.6 not 3.5 and 3.6 :)Jason

Is the beta based on 8.5 or 8.6?jpeyton - Friday, June 20, 2008 - link
Newegg had the Asus 4850 for $199 with a $30 MIR to bring the total to $169.People are reporting seeing the Visiontek 4850 on Best Buy shelves for $199, but this week's ad has all Visiontek video cards at 25% off, so that brings it down to $149.
$149 for a 9800 GTX killer? AMD is turning the GPU price/performance market on its head overnight with this release.

only if amd/ati could polish performance scaling with future drivers, 4870x2 in crossfire mode would really hit a hammer on every nvdian head.im so exited!!!BikeDude - Friday, June 20, 2008 - link
and how do these cards perform playing movies? Without resorting to the malware package aka "PowerDVD"?msgclb - Friday, June 20, 2008 - link
On your Crysis benchmarks why don’t you tell us if you’re using AA. You do for most of the other benchmarks. Does the lack of any AA = No AA? I was going to ask DX9/DX10, 32-bit/64-bit but you do list your operating system as Windows Vista Ultimate 64-bit SP1 so I’m guessing that you’re using 64-bit DX10.I get lousy Crysis results using Vista 64-bit DX10 with my dual 8800 GT SLI system but I get better scores than yours if I use DX9.
I appreciate all the work you put in to keep us informed.

we do 64-bit dx10 noAA for crysis.bob4432 - Friday, June 20, 2008 - link
hopefully this will drop the price of the 3850 :)GlassHouse69 - Friday, June 20, 2008 - link
When is a tech company going to stop sucking NDA manchicken?anadtech has lots of bruises on their knees.
"stay tuned kids for the 4870 while we polish off this knob!"
