Killer Mobile Graphics — NVIDIA's GeForce 8800M 89
MojoKid writes "Today NVIDIA unveiled the much-anticipated GeForce 8800M series of mobile graphics processors. The GeForce 8800M is powered by the new G92M GPU which is built on a 65nm manufacturing process and shares a lineage with the desktop-bound G92 GPU on which NVIDIA built their GeForce 8800 GT. The 8800M series will come in two flavors, a GTX and a GTS, with different configurations of stream processors, 64 for the GTS model and 96 for the high-end GTX."
Alienware already has two 8800M GTX models (Score:5, Informative)

Well, it's supposedly more mizerly (?) than the 512MB 8600m GT, which I have. With a 1.6 c2d, 2GB ram, XP Pro, and a 85WHr battery, I can get over 5 hours of battery life, which I think is dang good considering that I can play games quite well. That of course is not while gaming, only web browsing and using IM.
Of course, this will vary from laptop to laptop, YMMV.

Maybe the NVIDIA Technical Brief will yield some answers: http://www.nvidia.com/object/IO_26269.html [nvidia.com] (Warning, spawns a PDF)
PowerMizer7.0 Power Management Techniques:
Use of leading edge chip process
CPU load balancing
Intelligent GPU utilization management
Revolutionary performance-per-watt design
PCI Express power management
Aggressive clock scaling
Dedicated power management circuits
Display brightness management
Adaptive performance algorithms
CPU Offload Example (from NVIDIA's Technical Brief)
Figures 3 and 4 (see PDF) show CPU utilization when running a Blu-ray H.264 HD movie using the CPU and GPU, respectively. You can see that under the GPU video playback, 30% less CPU cycles are being used. This dramatic reduction in CPU usage means less power is being consumed by the processor, therefore system power consumption is reduced. resulting in longer battery life.
Note: Testing was conducted on an Intel Centrino based platform with 2 GHz Core2 Duo processor, and a GeForce 8600M GS, running Intervideo WinDVD8 playing a Casino Royale H.264 Blu-ray disc.

That effectively decreases the number of proce3ssors and of course saves a *lot* of Watts.

Yep, that might be true.. but to get to 256MB in graphics memory you have to spend $2499.00 US. That's just crazy. (MacBook Pro 15") I'm sorry, but I'll just get a iMac and purchase a cheap PC based laptop, and toss Linux on it. Personally, I'd love a MacBook but the bang for the buck just isn't justified. (spec wise, and the pro version is just insane price wise)

Apple was going 100% ATI, but then ATI leaked about how they'd got the contract to the press and Jobs was furious. He really HATES secrets getting let out (I've no idea why, it seems to be industry standard practice. But if you ever happen to enter a NDA with applie then you better honour it!)
Anyway, Apple pulled the contract and shifted every mac they could to nvidia. However, for some reason they didn't shift imac despite shifting everything else. I have a vague suspicion it is to force apple developers to always code in a GPU independent way (basically to keep nividia honest) but as an imac owner, it is very annoying.

You have to go pretty far back in Apple's product line to find a point where there wasn't a pretty even mixture of video card combination available.
