Saw it at another forum and it looked a little interesting, reading it now.

link doesn't work...

i think this maybe the right link

Good find guys! I like what I'm seeing there as to Sony's chip-growth and fab utilization plans.

Very interesting. Especially the slide about how they cost reduced edram chip (probably the GS) by extracting the edram and piggy-back it on the logics die.

If they would apply that technique on the RSX and add an on-chip dram of let say 16 MB for the frame buffer it would be awesome. Then the bandwidth issue of the RSX would be all gone.

edram not good for rsx, ps3 has 2 videoout with max 1920*1080 ,
with 128 bit hdr rendering framebuffers about 100 MB :D
and edram too slow

tile cache is the best way, with about 200GB/sec bandwith, and any local store on rsx with 1 terabyte/sec bandwith....

Are you sure, it seem dev have no problem on speed of eDRAM

Are you mean putting SRAM on GPU?

Is that official Nvidia data?

How large buffer for tile rendering does the PS3 require, mr Riddle?

do you heard from tile compression? :)

Compression yes, not specifically tile compression. Please give me some education how this is used in the frame buffer.

Thanks, nice slides, but I could not find anything about tile compression. Do you have more slides or could you describe it in your own words?
