As the Magic TNT is based on nVidia's reference design, there's no TV-out at all. Neither is there any resemblance of a fancy onboard fan, or any Witchdoctor capabilities to speak of. But don't let these facts deter you from the MagicTNT. It's not an undesirable product- the TNT doesn't really require a fan and who cares about TV-Out anyway? What you do get it a rather small AGP card with 16Mb SDRAM spread out over eight 2Mb memory chips which are capable of memory speeds of up to 125Mhz and of course the TNT processor itself which still has a heat-sink slapped on it.

At the heart of the TNT you still get the pixel-pumping TNT graphics core which works with two separate 32-bit rendering pipelines, enabling single pass multi-texturing, bump-mapping and advanced texture filtering with splendid image quality. Further more, the TNT has full support for full scene - order independent anti-aliasing under Direct3D which is nice (if a little unattainable in today's games). Better still though is the fact that you can control how this is done due and weigh anti-aliasing quality vs. performance in the Windows driver applets. As a fully compliant AGP 2x board the MagicTNT can take advantages of full AGP 2X texturing which it does. No other 3D board we've laid our hands on has proven quite as capable as the TNT in terms of handling huge textures (other than S3's Savage 3D via S3TC). Even with 32Mb textures the MagicTNT was able to maintain acceptable 26.2 fps at 800 x 600 resolution (tested with 3Dmark99), going down to 16Mb over 50 fps were squeezed onto the screen. You can't argue with that sort of performance.

When it comes to support for high-res 3D, the TNT doesn't fall short either, most games play adequately at 1024 x 768 and many even beyond that. Forsaken, for example, ran pretty much at a constant 60 fps with VSYNC on and 60Hz refresh. Disabling VSYNC, the Forsaken demo scored over 75 fps and gameplay was to say the least very smooth. The ceiling for the TNT in terms of 3D rendering resolutions is 1920 x 1200 rendering at 16-bit with a 16-bit Z-buffer and 1280 x 1024 rendering at 32-bit with a 24-bit Z-buffer. Knowing that the average monitor out there isn't capable of anything over 1280 x 1024 and in some cases (14 and 15" monitors) only 1024 x 768 you can feel well covered and supported.
