    NV25 Information

    I was browsing nVidia's forum over @ Fools, and there was a link to Reactor Critical. Here's what they have to say about NV25.

    Long-awaited NV25 based adapters. This graphics processor that have similar capabilities compared with XGPU is a lot more powerful than GeForce3 Ti500. Since it is manufactured using 0.13 microns technology, it has a lot of chances to be clocked at the very high levels. The GPU comes in January/February 2002, while professional boards should be available in the second quarter.

    ELSA is going to launch two boards based on NV25GL processor, both supports two LCD monitors, though, we do not know whether there are two integrated TMDS transmitters or only one and the second is external.

    NV25 that works on 275 MHz. 128 MB DDR SDRAM @ 250 MHz.
    NV25 that works on 300 MHz. 128 MB DDR SDRAM @ 330 MHz.

    So, this is what a high-end NV25 part *might* look like...

    * Rumoured 6 Pixel pipelines
    * Core freq: 300 MHz.
    * Memory: 660 MHz. (eff) ~ 10.5 GB/sec BW, assuming they stay with 128-bit data paths.
    * Supports TwinView
    * Supports (finally) Hardware iDCT
    * More powerful T&L unit, to include a second Vertex Shader
    * Can't find the link, but there's a rumour stating that we can expect Voodoo5 5500-esque Anti-Aliasing feature. The presumption is that the NV25 will bring a Rotated-Grid AA implementation to the table.
    * .13u Manufacturing process

    It really does sound like a pretty amazing chip. I would be willing to bet we'll be hearing a lot more in the way of rumours as the New Year approaches.

    Yeah, apparently they will:

    from the article:

    ".. A Voodoo5 5500-esque Anti-Aliasing feature. The presumption is that the NV25 will bring a Rotated-Grid AA implementation.."

    This is probably to compete with Ati's SmoothVision FSAA implementation, which is really quite slick. However, 3dfx was rumored to have really advanced FSAA implementations for their future Voodoo5 6000/6500 series. Perhaps the NV25 will include that.

    nvidia's drivers under linux pretty much as fast as they are under windows. There are not open source, but they work very well. OpenGL apps are fast under linux with them.

    Yeah you might say that Viewsonic's LCDs are not up to scratch. Take a side-by-side comparison between them and a Samsung screen. I don't know who makes the actual LCD, but Samsung's monitors look vastly better than Viewsonic's.

    Of course, you'll pay real money for the Samsung, but I don't know anyone else selling a 24" LCD monitor these days.

    You have to go for the Asus Deluxe line of cards(they make the same cards in multiple versions, Deluxe has a crappy TV tuner and digital VCR) or for an ATI All-in-Wonder line. The ATI has by far the best multimedia suite, it's tv-guide-like recording of shows and on-board mpeg-2 encoding kick-ass. the program is still a little slow and buggy, but incredible nonetheless.
    honestly though, I say save 50-100$ on the video card, and buy the tv-card seperate. that way a) save money on the video card b)no need to keep buying the 50-100$ extra card every year, since the capture card will still work just as well.
    As for Linux compatibility, I've heard mixed reports about all the Asus Deluxe and the ATI All In Wonders, so you'll have to search around online and take a guess.
