ATI Mobility Radeon 9800: Notebooks Get Next Generation Graphics

Homeworld 2 Performance
Homewold 2 shows very little impact from increasing resolution with the MR9800, but explaining why this should happen is a bit of a mystery. It may be a power management issue at lower resolutions, as that's where the MR9800 falls further behind the rest of the pack. We will have to look into this further, but for now, we're content to run HW2 at 16x12 with 4xAA/8xAF.

Thanks Dave, I've tweaked the conclusion a little to reflect this fact.As for the comparison systems, the only way to have a true and fair comparison would have been to grab an AGP version of the mr9800 and dropped it in our desktop system. Since we couldn't do that (or shove other GPUs in the notebook) we went with our standard graphics testbed.
This isn't a direct comparison, and we mentioned that we only used other ATI cards because of that fact. Numbers other than the MR9800 are just for reference.

Derek,Its up to the notebook vendors to qualify the drivers, not ATI. ATI can supply the drivers to the vendors, but its up to the vendors to qualify and release them.

If the graphics drivers are lagging behind, can't you use a driver which works with all cards - like the Omega ones? The same driver works with the Mobility series and the desktop ones, would that help out? I don't think it disables Powerplay either.Does anyone know what the power drain of the laptop is during a heavy gaming session? Or how long it lasts on batteries?

I have to reiterate what #13 said. Why did you compare a P4 notebook against an Athlon 64 desktop!?!?!? And why the differing memory configurations!?!?!? Since you are comparing the video cards, it would SEEM like a good idea to get the configurations as close as possible. Certainly you could get closer to parity than THIS choice!My $.02

I agree, I keep my laptop graphics cards at stock, it's not worth overclocking for a small performance increase, especially when it is usually difficult to replace the graphics card.John

#14 Maybe Powerstrip will do, but not recommended....Besides overclock just to get from 200 to 220, 100 to 110, 50 to 55, 25 to 27 in some games.....
Just to say that when you already have a lot of fps you will get even more (not needed) and when you have low fps, you will continue to have low fps….
In very resuming words OVERCLOCK does not compensate.

Usually it's just the same as overclocking a desktop graphics card although obviously you have far less headroom.John

just out of curiosity, anyone know if it's possible to overclock a video card in a laptop?reboos - Thursday, August 19, 2004 - link
comparing a Athlon64 3200+ w/ 1 gig of RAM to a Northwood 3.2 with 2gb of RAM. I don't get it. :\Shalmanese - Thursday, August 19, 2004 - link
No Doom 3 benchmarks? :o :(
