Is all of these thinkpad models that feature this trident video chp have discrete video onboard not shared has decent performance? I have one thinkpad 600E with neomagic yet to envaluate and a 600 coming by mail.

I wanted to know about mobile trident as I had poor experience with trident video cards for desktop PCs.

thanks and cheers, thinkpadcollection

Judging by the PSREF sheet, the 600 can only output a maximum external resolution of 1024x768, while the 600E can do 1280x1024. Both video chips in the machines are very old and you probably won't find a big difference in performance even with semi-modern apps.

The NeoMagic chip would have higher performance even if it was another NeoMagic design in the 600 simply because the 600E is a more powerful design.

As I know no one 600/E/X has trident, all are NeoMagic.
Trident can be found in 770-series. NeoMagic and Trident are dedicated video memory cards, Neo have integrated on-die memory, Trident - dedicated memory chips.
But trident looks better - 8mb version can 1024x768 32bits and 1280x1024 24bits when Neo can only 24bits. Another trident advantage - Direct3D acceleration in W9X, performance is about 441 points in 3DMark99. DDraw acceleration seems same.

Oh, derp. For some reason I forgot about the 600 having the MagicGraph128. Disreguard my previous post.
