Graphiccards overview

ST was only involoved in the Kyro series of PowerVR cards, before that it was NEC.

The G400 was a 2x1, the second "tmu"/"thingie" was added with the G550.

And the G400Max ran at 150MHz core.

 

BSD Geek is right, G400 is a 2x1 design at 125 MHz core speed (166 MHz SDR memory, was it SGRAM or not?), thus 250 MPix/s and 250 MTex/s. The Max is the same chip at 150/200 MHz, thus 300 MPix/s and 300 MTex/s.

You could also have a "notable new features" column. SLI for Voodoo2, DualHead for G400, etc.

And of course you'll include all the various Glaze3D specs in your overview too, it won't be complete without it

 

hiostu, great work.

Thanks.

 

About TMUs, yes you should try to figure out (at least with the older chips when these things were simpler) whether the architecture was capable of bilinear or trilinear per clock, enough bandwidth assumed.

Dunno what would be a clear way of describing DX8/DX9 class gear, maybe textures per cycle, and some verbal comment on the method/bandwidth efficiency with regard to anisotropic filtering? (As bilinear and trilinear don't matter so much any more performance-wise.)

Best wishes on your effort!

 

Ah, coupla more things:

Voodoo3's codename was Avenger, wasn't it?

And you could lump NEC and STM/PVR together for clarity, same team (Kyro is Series 3) and everything...

You can find comments on NV1, those older Savages, and Number Nines here:

And some more stuff about features (but not fillrates) here:

for all 3dfx cards you can use the pics and info from my 3dfx site (in sig). it pretty much has everything.

 

I've collated various card specs here:

http://freespace.virgin.net/neeyik.uk/3dspecs/

Obviously I can't guarantee that it's all 100% accurate but a good proportion of it is.

 

I suppose you should also add the Mystique G200. It's the same as the other G200s really, other than the fact that it uses SDRAM instead of the SGRAM on the Millenium.

Codenames:

Parhelia is Parhelia

G400 - Toucan.

G450 - Condor I.

G550 - Condor II

G200 - Eclipse

G100 - Twister

 

some of the early clock speeds are incorrect, but i'm not sure about the correct values either.

rage II ran at at least at 50 MHz, But might have needed more than one cycle to do a bilinearry filtered single-textured pixel.

(even older 2d trio64 ran at about 50 Mhz but could be oveclocked to some >70 )

 

another interesting (and quite old) pages are here:

all mentioned pages contain several mistakes, it's not easy gain informations about old cards

there's some mistakes too (NV35-38: 350 MHz DAC ?, ...)
