The Test

Unfortunately, we are somewhat limited in our ability to compare this solution to comparable notebook or desktop systems.

We don't have an Alviso based desktop solution (and we haven't seen many Alviso based notebooks yet either). This means we won't be able to compare cards running on the same platform with the Go 6800 Ultra. We also haven't gotten our hands on a Mobility Radeon X800 systems with Alviso in them.

So, what we are going to look at today is the highest end notebook we've yet seen (in terms of graphics speed) compared against the high end desktop configuration we used when testing SLI graphics. This will serve to give us a good picture of where ultra high end notebook performance falls with respect to ultra high end desktop performance. As the core clock on the GeForce Go 6800 Ultra is higher than most desktop GeForce 6800 Ultras (400 to 425 depending on the vendor), it's very possible we could see some interesting numbers come out of this. Of course, the notebook's Pentium M 2.13GHz processor will limit the performance of the system compared to our Athlon 64 4000+ desktop. We aren't likely to see the Go 6800 Ultra paired with anything but a Pentium M due to the TDP requirements of vendors. Mobile Pentium 4 and Mobile Athlon 64 parts are still too hot to be able to economically run a Go 6800 Ultra as well.

The test setup for the Dell Inspirion XPS we tested was as follows:

Intel Pentium M 2.13GHz
Intel Alviso based motherboard
1GB DDR2 533 4-4-4-12
NVIDIA GeForce Go 6800 Ultra (clocked at 450/1100)
Windows XP Service Pack 2 with DirectX 9.0c
NVIDIA ForceWare 75 series Drivers


Our desktop nForce 4 system was configured thusly:

AMD Athlon 64 4000+
ASUS A8N-SLI Deluxe (nForce4 SLI) Motherboard
1GB OCZ DDR400 3-3-3-10
NVIDIA GeForce 6800 Ultra PCI Express (clocked at 400/1100)
NVIDIA GeForce 6800GT PCI Express (clocked at 350/1000)
Windows XP Service Pack 2 with DirectX 9.0c
NVIDIA ForceWare 69.33 Drivers

The only unknown factor here is the performance difference beween the 69.xx and 75.xx ForceWare revisions. The Dell is the only notebook we've tested with a 75 series driver.

    If im not mistaken, the only difference between the GT and Ultra are their clock speeds #7. These benchmarks are baffling. I'm having a hard time believing them. How on earth did they pull it out?

    Is this a prelude to what's to in the next generation of desk top cards? I'm think, if they can make a mobile card this fast, they should surely make a faster desk top counterpart with less heat, space, and power restraints.

    Odd how a 12pipe / 5 vs @ 450mhz can out pace a desktop 16pipe 6vs @425. What optimisations have been done? I can understand it beating a 6800gt due to greater vertex/pixel shading power (450 x 5 vs 350 x 6) but it shouldnt beat an ultra.

    Is the nv41m on 0.13 or 0.11um ? the die seems quite large any idea on transistor count?

    It's about the cheapest go 6800 laptop, but it includes the fastest version.

    You can configure one now. $2745 for a well equiped system. Intenal Audigy, 6800 Go Ultra, 2.0Ghz P4 "760," cdrw/dvd drive, 1GB ddr2. Not bad for what it can do. Reply

    Amazing, just a few years ago the idea of gaming on a laptop was laughable. Now you can get a DTR that can pretty much keep up with the latest desktops - wow!

    Not just battery life... but cost. This has got to be a $3k+ machine :(

    For a laptop to come even come to close to desktop performance is simply amazing. so be on par with? Wow, just wow.

    they manage to do all this with a laptop battery and cooling?

    I would really like to see that go card translate into a desktop part. It would make running SLI a little easier.

    We would too :-/

    We just didn't have time to perform any battery life or power tests as we had to spend all the time we had with the system benchmarking games.

    I would love to see the battery life for this thing. Reply
