NVIDIA had a large booth but didn't have any new hardware on display. They did, of course, have the news that they were going into the X-Box. They also announced a relationship with Interplay where Interplay will develop future titles to take advantage of the GeForce's abilities.
We also managed to view a special version of Quake III that has been visually enhanced for NV-15. Though shown running on a GeForce and therefore not as fast at it should be eventually, the images were quite impressive. (One sequence even had cute little NVIDIA chips gliding down a production line.)
AMD was showing off their 1GHz Athlon in several systems. Let's just say that Quake III Arena and Unreal Tournament were running pretty darn smoothly! Athlons also appeared in several 3dfx machines loaded with Voodoo5s, which were all performing well.
Intel also had their 1GHz processor on display. Backing it up were several development tools, which should help developers track bugs and improve performance when developing on Intel hardware.
They also had a nifty web livingroom setup, complete with inflatable furniture, flat panel giant TV/net hookup and remote keyboard. Mostly used by exhausted attendees, it also served as a great promo billboard for whoever had control of the keyboard...
Apple had their normal clean white booth front and center. There was a marked difference between the Apple booth's appearance the rest of the booths. Apple's was almost antiseptic in comparison.
Inside they had several Apple Cinema Displays, the 22" LCD, which we all drooled over. One of them was playing the trailer for Bungie's upcoming title Halo. We drooled over that too.
They also had a couple of AirPort wireless LANs setup with Quake III Arena and Unreal Tournament. The frame rates weren't up to our high standards, but the ability to easily put a LAN party together is appealing.
