nVidia has officially unveiled its latest mobile graphics solution, the GeForce Go 6600. Aimed at the mid-range laptop market, it fits between the GeForce Go 6200 and the GeForce Go 6800. nVidia believes that the GeForce Go 6600 will deliver twice the performance using the same amount of power as its previous generation high-end mobile chip, the GeForce Go 5700 FX.
Thanks to its low power requirements, the GeForce Go 6600 marks the first time that a performance solution has been available for thin and light notebooks. nVidia claims that the part will deliver between 5,000-7,000 points in 3DMark03 depending on the clock speeds, ensuring that this is definitely a viable solution for the mobile gamer. The part offers DirectX 9.0c support and we expect that all current game engines should run at a playable frame rate. We will have to wait until we manage to source a suitable notebook to discover how well it does in benchmarks.
But impressive 3D performance isn’t the only feature that the Go 6600 has to offer. At the launch last week, nVidia was actually pushing the part’s video features harder than its 3D capabilities. With High Definition (HD) video becoming more popular this seems like a clever move by nVidia. PureVideo, a feature taken from the desktop parts is present in all of the mobile chips, but additional features have also been incorporated.
One of the most interesting laptop specific features included in the chip is something called intelligent LCD colour enhancement. nVidia demoed this at the launch and unlike many hyped technologies it made a genuine difference to how images looked, especially with fast moving video.
Only certain laptops will support this technology as for it to work the nVidia chip has to be aware type of specific details of the panel used in the laptop such as response time, among other characteristics.
In a nutshell the intelligent LCD colour enhancement works by tricking the LCD panel into believing that it should display a higher colour value than it really should.
By doing this the panel will reach the actual intended colour much faster producing a much crisper picture for richer colours. On a conventional display, the LCDs will switch to the next colour before they have actually reached the desired intensity, causing pictures to look washed out, especially for fast moving images.
nVidia has also incorporated several video enhancing features, the functions of which have up to now been performed by cost adding third-party chipsets. If we are to believe nVidia, this should also lead to improved image quality, especially during video playback on any notebook using a GeForce Go 6 series graphics solution.
PowerMizer has been upgraded to version 5 and includes even more advanced power saving features enabling more parts of the GPU to be switched off when not in use, which should result in longer battery life
The GeForce Go 6600 will be available from today and will ship both as a chip solution with embedded memory and on MXM modules. nVidia seems to have amassed huge market support so expect to see a wide range of new laptop models from several big brand manufacturers over next couple of months, with Toshiba being one of the first to have products ready.
