How much ram are you expecting in next-gen consoles?

Sorry if this has been covered before, I'm new. I'd like your opinions, many of you seem extremely knowledgeable about hardware, something deep inside me says that 512 megs of ram over-all when all is said and done is the max to expect *sobs*
 
512 would be a lot. However I fully expect a throwback to 2 megs of ram... since nobody needs more than that ;)
 
For which system ?

Ps3 i'm expecting 512 megs total.

Ns5 i'm expecting around 300+ total

xbox 2 i'm expecting 700+ (reason for the xbox 2 to have more ram is because it will be useing slower ram and less onboard ram and it will be using ram from the pc sector which is being massed produced for gpus anyway and the price will come down quickly )
 
PS3

256 MB min to 512 MB max external XDR
32~64 MB eDRAM on CPU
32~64 MB eDRAM on GPU

320 MB memory total, min
640 MB memory total, max

Xbox Next

256 MB external memory, min, 512 MB max
10 MB eDRAM, min, 32 MB max
1 MB L2 cache min, 2 MB max

267 MB min
546 MB max

Dividing it up as you did is fine. I was speaking on a whole 512 would be the max seen on any console, I hope I'm wrong.

I think u will see more edram on the gpu than 10 mbs . More like 32 mbs minimum and the same with the cpus .

I'm thinking a 5meg cache per die .

Some where over the rainbow maybe, in the land where Dreamcast rule and Atari Jaguar's roam free :p, but down here on planet earth expect the conservative numbers.
 
what does one do with eDRAM? and....why so much?

On chip framebuffer, Z-Buffer, large on-chip texture caches.

You'd want a lot of it this generation if the console supports HDTV resolutions and or FSAA.

Unless there are other ways to support HDTV and FSAA without requiring large amounts of eDRAM...

Considering PowerVR has (at least in previous generations) tiny amounts of RAM on chip for its backbuffer and it managed to support high res PC and DC games, there are other ways.
 
At this moment it seems clear from leaked info on the xbox2 side..and issued patents ont the ps3 side..that both of them will employ tile (non deferred!) rendering.
 
DeanoC

Your preaching to the converted :) Just answering the question of why a company might want to use a lot of eDram in a console.

How could a GPU do tile rendering of the sort that DeanoC mentioned (that would allow a frame to be rendered section by section in on chip ram) without deferring to store/sort the geometry first?

Just build N viewports with N display lists :) This could be done by the developer or by the API. The hw don't need to store and tag with tile ID each vertex, and don't need to defer shading. This approach is not efficient as a TBDR..but it's effective in requiring a small memory footprint for back buffer and z-buffer.
 
I am guessing between 384MB and 512MB RAM, with maybe some sort of upgrade slot up to 768MB RAM (+ 256MB). All depending on the manufacturing cost.

VADE RETRO SATANA!!!!!! Memory upgrades are sooooooo 90's.......
