I’m sure it will offer a Kaleidoscope of things.
Brimstone:
The Rambus tech that theInc talked about there is Yellowstone (4 signaling levels), and it seems like it's canned. Rambus XDR DRAM use 2 signaling levels, but is still 8 bits for each master clock.
You're right that it's different from QBM, and probably diffferent from whatever XDDR that ATI might come up with.
QBM seem to be still-born. I don't know ho many years it's been supposed to come the next year. But I never see any products. And they have never even demoed any prototypes that could fight with the high end DRAM that were out on the market at the same time.
I'll be nice and say that maybe one day they'll be able to take very low end memory and double the speed to low-mid speeds. But I wouldn't be surprised if that never happened. They'll never be on a GFX card.

Kentron doesn't seem intrested in charging for their patents, so ATI and VIA can probably use whatever they need. I'm not so sure XDDR will be radically different from QBM for that reason. A big factor in this I would assume is the X-Box 2. If XDDR ends up on PC's as well as a console, it will help keep prices low.
Microsoft has set standards high with Longhorn. Dual Core CPU, DX9 graphics core, and so on. I'd think Microsoft would be agressive with XDDR standards as well.

I really dont understand the basis of your comment. Virtually every feature released by Ati and Nvidia gets used in at least one or two games. The Marjority of fetaures are based on Standards of some type that everyone uses.
More importantly, End Users, *Don't* use features. Game developers Use Features. End users get the benefits of whatever Game Developers put into their Games. Which will end up being most of the base feature list of the next Ati and Nvidia VPU.
Performance Wise the next product will be a similar performance jump as the last Series was. It will not doubble performance in all areas but some important areas undoubtedly will be. That goes for both Companys.

kind of like sm 2.0 on the r300 series, 3dc on the r420, sm 3.0 on the nv40 and it goes on. the r300 was released 2 years ago? and we now have 3 games which use sm 2.0? far cry, tomb raider, and the single heat distortion effect in doom 3.
im sure by the time the nv50 comes out nvidia can double the speed of the nv40 in a lot of areas. i doubt ati can do it with the r520 if it rly is scheduled to be launched summer of 05.

(not 100% sure of all, but i recall these having either PS 2.0 or VS 2.0 support - these games are all available atm at least as demos, if not full game)
GunMetal
Ground Control 2
Counter Strike: Source
Painkiller (newest engine builds)
Tiger Woods PGA (or whatever the EA Sports golf game is called) 2k3 & 2k4
Madden 2004
Star Wars Galaxies
Medal of Honor: Pacific Assault
bah.. I'm sure there's several more but I can't remember them now

painkiller is a rearded 1 level tech demo, that doesnt qualify as a game. id hardly classify gun metal as direct x 9. ill give you cs source, that makes 4. ea sports games might 'support' direct x 9 in some retarded trivial typical ea manner, altho i doubt u can classify them as direct x 9 games. as for starwars and medal of honor, they might as well be direct x 7 games, they certainly look like it.
so basically you have 4 games that use at least part of the feature set of the 9700 pro, a 2 year old card. so basically with the r520 it will come down to much fast it is, not how many useless features they can cram into it for marketing reasons.
This isn't a discussion about games or feature useage.

Well the EA golf games use it for water (surprise surprise), as does SWG.. but I think you're mixing MOH
A (SP & MP demos just came out) with older MOH series games which were based on Q3 engine, the new one has D3D renderer.But as Dave said, this isn't discussion about game features etc, so I'll end it on my behalf here.
I spoke of embedded memory in a previous post on the forum (concerning the cost and its use) and i think this might be part of the equation ATI could possibly use in its next generation. Using this ram for texture stores and swaps would have a big impact on speed and bandwidth if incorporated correctly wouldnt it? (say around 10 to 20 MB of embedded ram?) ATI and NV are also know for refining and progressing their use of algorithms (some good some questionable on both sides). Ive also read (here on b3d and other places) about the Fast 14 technology which ATI has invested in?
Quick question on Fast 14 technology...Could this technology give ATI a little more headroom in the clock speed area? Maybe a way to help in reducing transitor count, Control heat to produce much higher clock speeds. Again im only theorizing and im new to this so be gentle if Im way off base

What would be the best solution for next gen hardware?
1. As we have know gddr3 just higher clocked and maybe with a wider bus width(>256bit)
2. some new memory like qdr or something
3. a small amount special fast memory like eDRAM combined with common gddr3 and virtual memory support
4. a combinaion of the above
5. something not mentioned
