How much vram does gamecube and x box have?

I just been wondering ?  I heard gamecube has 3meg of vram and  xbox I\'\'m not sure.  Does anyone know?

I\'ve heard about the GC\'s 3meg thing.I\'m not sure I haven\'t really checked out the GC, *note to self,get informed about everything GC

The X-Box has a unified memory architecture (UMA).64 megs of shared memory,the programmers deside how much memory the textures get\'s etc....

Thank you,  is that better than having vram?  Having unified memory architecture instead of as certain amount of vram.  Then how can gamecube be texturzilla if it only got 3 megs of vram?

Sunnyvale-based MoSys is the company behind 1T-SRAM technology, which will make the graphics chip and the Gekko CPU work in perfect harmony with each other—and at blazing speed. There is 24MB of 1T-SRAM main memory the Gekko CPU and Flipper graphics chip can access. As of the year 2000, this is one of the largest implementations of static RAM in consumer product history.

Again from IGN
S3TC, which is hardwired into the graphics chip provides a 6:1 ratio for compressing textures. Which means if a developer wants to cram 50MB of textures into Gamecube, it will only cost them about 8MB of memory space, and because the technology is part of the graphics chip it won\'t affect the system resources. What all this means is that Gamecube features exquisitely detailed textures with great variance instead of ones that are monotonous and blurry.

If you haven\'t come to an understanding by now, simply know that S3TC will be a very important part of Gamecube\'s graphical abilities; in fact, one of the most important. By employing S3TC in every game from the systems launch forward, developers will achieve stunning graphics. In the end, texture performance is the perfect marriage for Gamecube\'s high polygon pushing performance. As cliché as it sounds, S3TC is the icing on this graphical cake.

I know I just posted; but I really didn\'t feel like editing.

Thank you guys.  That really helped out, there\'s alot stuff to these systems specs today.

It depends on how you look at it.Since it\'s up to the programmers to deside on how huch memory everything needs.He can make a game with amazing textures,but with bad AI and bad sound.

It should also be noted that the X-Box supports S3TC like the GC.Every nVidia based GPU supports it,and old S3 based chips.

A fixed amount is probably best, developers know what they are doing then. Although that mix and match X-Box thingy could be very good as long as theres enough ram to go round.
