lots of embedded RAM in R500 ? (maybe nv50 also?)

It sounds like ATI and perhaps even the whole industry will be moving to put
embedded memory (not just small caches) on their GPUs / VPUs.

The ATI R500, slated to come out in fall 2005 with DX10 compliance, might
have a significant amount of embedded memory.

The Graphic Chip

"The graphic chip will be based on the the R500. This VPU has been in design
at ATI's Marlborough, Mass. office. It'll be fully compatible with DirectX
9's PS and VS 3.0 and the next version of DirectX: DX10, the same suite of
APIs that will be used in Longhorn.

What nobody is telling you and you'll know about this first, here on
TeamXbox, is the revolutionary approach of the Xbox 2 to deal with today's
biggest problem in graphics chips: memory bandwidth.

The graphic chip will contain not only a graphics rendering core but up
embedded DRAM acting as a frame buffer that is big enough to handle an image
that is 480i and can be 4 times over sampled and double buffered. Yeah, we
all remember Bitboys but this time you can bet this is for real. This
solution will finally make possible HDTV visuals with full screen
Anti-Aliasing on."

now if ATI is going to embedded memory with R500, is it likely Nvidia will
also, with NV50 ?

sounds good.

This isn't the first time I've heard about embedded memory in future ATI
and nVidia products. It wouldn't surprise me if they implimented small
caches (4-32 KB) for the pixel and vertex shader instructions as well.
However, manufacturing a chip with over half a billion transitors isn't
cheap, even for 2005 (~260 million for just 32 MB of eDRAM, the rest
logic). Thermal and power issues would also be a great concern.

This is BS for the gullible masses.............. !!

The reason for any embedded video RAM in the Xbox2 is COST !!!
Notice the 480i limit. Tailored for the typical video screen. Saves
having off chip video memory and testing it.

But pretty much all the major players are going to have to do this, by 2006.

Sony (Visualizer)
ATI/MS (R500, R5xx)
ATI/Nintendo (N5)
Nvidia (NV50/55)
