3dfx Rampage

[RafalB]

tylko pomyślcie co by nas czekało gdyby 3dfx nadal istniał:

 

This is a repost from a repost of a repost.....dunno who to give credit to..

 

But these are SUPPOSEDLY LEAKED SPECS...and very likely to be BS, but still fun to see.

 

With Rampage 3dfx will have T&L ,a feature missing in the VSA 100 because 3dfx thinks is more opportune to solve the aliasing and the common rendering problems before the geometry problem. However don't think 3dfx's T&L will be as the T&L engines we have seen up until now. Even in the T&L case 3dfx has chosen its own and original method in fact the T&L functions are separated from the rendering chip and are done by an external dedicated processor. There are rumors about this external processor being the Sage, the chip which was believed to be the successor of Rampage but this is unconfirmed. This solution of an external T&L engine has had many advantages the first of which is the ability of doing chips with few transistors,somethiing that combined with a smart productive process will allow 3dfx to really increase the running frequency.

 

Let's see the features of the single Rampage chip ( the rendering chip):

 

0,18um productive process

 

Scalability similar to VSA 100

 

4 pipelines with 1pixel/1texel

 

200-250MHZ core clock

 

All the VSA 100 features plus:

 

Advanced T-buffer ( probably the ability to perform 8 samples effects)

 

All the pixel shading functions supported by DX8.0

 

Hardware higher order surfaces or curved surfaces

 

Photorealisitic rendering

 

New texture combine modes

 

Ability to do the quadtexturing

 

200 MHZ DDR memory

 

Nothing more is known about the rumored voxel unit and the supposed improved version of the FXT1 texture compression.Nothing also about the Photoshop effects in hardware.

 

Features of the T&L unit ( supposed Sage):

 

Very little in known about this except that it will be handle 75 million polygons and up to 25 lighting sources in hardware. Obviously also the T&L unit will be SCALABLE such as the Rampage.

 

Configurations and scalability:

 

Also this new generation from 3dfx will be a multi chip solution. There are three possible configurations:

 

Entry level configuration composed by 1 chip Rampage and 1 T&L unit. As you see the minimum is 2 chips.

 

800Mpixel fill rate ( core clock at 200MHZ)

 

75 millions of polygons

 

6,4GB/sec memory bandwidth

 

Middle level configuration with 2 Rampage and 2 T&L unit . 4 chips at all.

 

1,6Gigtexel fill rate ( core clock at 200MHZ)

 

150 millions of polygons

 

12,8Gb/sec memory bandwidth

 

High end configuration ( similar to the actual V5 6000) with 4 Rampage chips e 4 T&L unit. 8 chips at all for amazing specs!!....

 

3,2Gigapixels fill rate ( core clock at 200MHZ)

 

300 millions polygons

 

25,6GB/sec memory bandwidth

 

The chip will be unofficially announced at ECTS in September. According to 3dfx it should be available in December ( if everything goes for better..

Pomysl sobie, ze juz o tym czytalem jak jeszcze 3dfx istnial. Wtedy byla to moc niewyobrazalna, dzis prawie normalka.

... no to mam chlopaki dla was niespodziewanke...

 

Paru koles iz 3dfx (RIP) wzielo sie w garsc i w GARAZU czy innej wynajetej FABRYCE odradzaja firme!!!! Mam nadzieje ze wyjdzie im to dobrze... z checia bym znowu zobaczyl ladna animacyjek 3dfx przy starcie gry ;)

Ciężko to widze. Ale niepowiem. Jak ostatnio zobaczyłem animke z 3dfx'a na voodoo1 w glidzie mi się łezka zakręciła.

hih znam to mam jeszcze starego v1 dobrze powspominac dobre stare czasu :)

[bruce]

troche to stare

[samhain]

... stare nie stare ale mojego (znaczy bratu wytlumacze, ze to MOJE ;)) VooDoo NIE oddam i .

[ct1]

Err...these specs are way off.

 

I'm sorry. but if they say 4 chips and 4 T/L units or even 2 + 2 they completely misunderstand how T/L unit works.

 

Anyway, I'm not here to be picky, so I'll post Rampage specs from Las Vegas presentation on September 2000.

This property legally belongs to nVidia and it was confidential, but now knowing that they won't use 3dfx tech in they product who cares, right?

Ja mam jeszcze voodoo 1 i voodoo 3 w szafie. Kiedyś muszę włożyć voodoo 1 i zobaczyć ile będe miał w 3dmarku.

[Gość]

ja mam v1 i gf2mx 400 i wiecie co?

Na mx mam doopna grafike (jakosc) a na v1 super

sprostowanie v1=Voodoo rush

[Jackk]

Pewnie gf masz jakąś Chińszczyzne :( .

[BILL_BLANT]

Przeciesz to wszystko zaczeło się od 3dfx`a pamiętacie v 1 ajak kupiłem sobie kiedyś diamond monstera v2 moc!!! zpowiadało się pieknie...

kto wie może n vidia skończy tak samo :D :D :D mam nadzieję HA HA

[Radek]

Prędzej padnie ATi T_T

[Memphis]

VooDoo wróci. 3dfx RULEZ. Chociaż szanse są marne, ale trzeba miec wiarę. :) 8)

Bo NVidia nie dba o jakość obrazu tylko o szybkość i punkty w 3DMark-u :evil:

[RafalB]

voodoo zawsze był dobry (pamiętam jak na v3 2000 ,żadna tnt2 w klasie nie mogła się ze mną równać ,koledzy polecieli na 32 bit bo pan w sklepie powiedział ,że tak jest lepiej a ja wolałem wydajność ,glide oraz świetny obraz) nawet v5 mugł konkurować z gf3 gts zobaczcie se artykuł na (hardocp)
