Hello again, everyone here at PCW.
Very recently, the most powerful video-cards on the market for laptops were Nvidia's GeForce Go 7950GTX (Direct-X 9) and the GeForce Go 8700M GT(Direct-X 10). Well, Nvidia has broken their own record on the laptop GPU(Graphical Processing Unit/Graphics Processing Unit) market with the release of the GeForce Go 8800M GTS and GeForce Go 8800M GTX (Both Direct-X 10).
So, ho much do these cards stand up to their desktop big brothers, as well as the previous two champions(7950GTX and 8700M GT)? Well, on a first note, these cards carry a formadable price tag, quite a bit more than the 8700M or 7950GTX. Here is a direct comparison of the laptop/desktop differences:

As you can see, the mobile GTS beats the desktop GTS(320MB/640MB) by 50MHz on the shader-clock speeds, which would help if you play the Elder Scrolls IV: Oblivion, which is heavy on pixel-shading capabilities. One downside to the mobile GTS is the fact that it has less stream-processing capabilities than the any of the desktop GTS(s). Other than that, the mobile GTS is equal to the desktop card, which is very good considering that this is a laptop card. (My opoligies for not being able to find the Memory Bandwidth and Fill-rate of the 8800M GTS; it wasn't on Nvidia's site or anywhwere else.) Something else to note: I found a conflict on the clock-speeds of all three cards when looking at Newegg specs and Nvidia's comparison chart(desktop GTS only), so I listed the lower speeds.(Nvidia's site.)Now, on to the GeForce Go 8800M GTX versus the Desktop GeForce 8800GTX:
| Specs | *GeForce Go 8800M GTX * | (Desktop) GeForce 8800GTX |
| Clock-Speed | 500MHz | 575MHz |
| _Mem-Clock _ | 800MHz | 900MHz |
| Shader-Clock | 1250MHz | 1350MHz |
| Stream-Processors | 96 | 128 |
| Memory | 512MB GDDR3 | 768MB GDDR3 |
| Mem. InterFace | 256-bit | 383-bit |
| Slot | PCIe x 16 | PCIe x 16 |
| Mem.Bandwidth | (unknown) | 86.4 GB/s |
| Fill-Rate | (unkown) | 36.8 billion/sec. |
As you can see here, the desktop version of the GTX easily trumps the mobile version of the GTX, but for a laptop card, the new GTX sets records. And, when you think about it, the mobile-GTX isn;t far behind its desktop counterpart as far as clock-speeds go. And again, memory bandwith and fill-rates were nowhere to be found on the mobile-GTX.

So, looking for kick-a** video card for your laptop? Then you might want to consider a GeForce 8800M.( As of 12/21/07, Vigor offers a notebook with 8800Ms) Alienware is also expeted to release a notebook featuring the 8800M series in the near future.
