Huckleberry Finn sends word of a post by Epic's Mark Rein to the Epic GT NVIDIA Forum that gives a feel for NVIDIA's announcement later today (as well as the fact that Mark probably hasn't signed an NDA). Here's a portion:

Nvidia is definitely going to change the world of graphics.

Nvidia is going to announce the GeForce256 which is the product name for the NV10 their new "GPU" chip which supports hardware accelerated transform and lighting. Tim Sweeney and I saw it running behind closed doors at Siggraph and we were totally blown away. We saw some incredible demos with previously unimaginable numbers of polygons in real time, fully-lit, game-quality framerates and resolutions.

Nvidia is going to ship it this September and from a practical standpoint it's approaching the power of Sony's next generation Playstation's graphics hardware.

What's really interesting is that this is just the start of some pretty amazing hardware to come from them. They released TNT2 only 5 months ago and here they are today with GeForce256 less than a month away. Just think what kind of chip they'll be shipping when Sony's next generation Playstation actually does arrive.

Here's the cool part. Looking forward to Fall 2000 you'll probably be able to buy a Celeron 600 or AMD Athlon 600, 128Mb of RAM, a DVD-ROM, a 15+ Gb hard drive, a monitor and a GeForce256 in the $1,200 range from name-brand companies like Dell. Wow!
