General
Magic3D TNT2 is based upon nVIDIA's Riva TNT2 chipset. And has 32 Megabyte SGRam onboard.. Package is bundled with a driver CD.

Lets get this review going people ...
Skywell technology has outdone themselves this time. With their desent, flexible and dynamic market strategy they have expanded their Magic3D product line-up with several new 3D chipsets like Voodoo3 (reseller only), Savage4 and last but most certainly not least nVIDIA's TNT2 chipset, which ofcourse we will review.
To put it in other words, welcome to the 3rd generation high-speed 3D videocards.

Skywell, as any other manufacturer had to go with a new chipset-manufacturer since the 3dfx/STB merger. They have choosen nVIDIA as their biggest partner for a well built strategic alliance in the hardcore videocard bussines.

Skywell's TNT2 line-up will be consisting out of  3 different TNT2 cards.

  • Magic TNT2 With 32MB @ 150 MHz
  • Magic TNT2 With 32MB @ 150 MHz with S-Video & Composite video out
  • Magic TNT2 Ultra, the same as Magic TNT2 but its floating at an incredible 183Mhz chipset clock and memory clock
  • there will be a TNT2 version with TV-In and TV-Out options also.

With a 150Mhz, 32MB SGRAM memory, 300Mhz RAMDAC equiped Magic TNT2 you'll get about 300 Mega freaking pixel per second fillrate, 9M million triangles/sec peak, massive 2.9GB/sec frame buffer bandwidth, and with excellent 3D Game features like 32 bit rendering, 32 bit Z-buffer, 8 bit stencil buffer, anisotropic filtering, bump mapping, it also includes DVD/MPEG-2 software player, and TV out function (optional, PAL/NTSC, S-Video and Composite video output, SW-TGATNT2TV), to be a complete solution in Multimedia system.

With AGP 2x/4x interface, full sideband support, AGP texturing, Magic TNT2 can have a wide range of applications from the hottest 3D games to full screen, 30fps DVD playback.

The TNT2 is manufacturered with a 0.25 micron manufacturering process. it currently produces 125-150 MHz chips. Later this month we can expect the ultra TNT2 series chips which will go at the incredible speed in the 175-185 MHz range.

Compared to TNT (1) the TNT2 is ofcourse a hell-of-a-lot faster, but also carries AGP4x support which will become available later this year (probably summer/fall '99). Another great new feature on the TNT2 based cards is the ability to do hardware motion compensation. This feature will reduce CPU utilization bigtime while playing MPG/DVD (MPEG-2) multimedia files. Other major advantages are full 32Bit 3D gaming support and ofcourse a texture mapping size of 2048x2048.

The box comes with no games and/or demos. Simply a driver cd. (you should however get the latest drivers from nVIDIA.com) The included drivers were outdated. Furthermore a simple but efficient and well writtten manual was included to get even the lame a TNT2 card installed with ease.

Coming up - benchmarks
