The NEXT LAST R600 Rumours & Speculation Thread

The recent trailer was on an Xbox 360 dev kit (at ~25fps) according to repi on the B3D console area.

 

Yes, next week on GDC https://www.cmpevents.com/GD07/a.asp?option=C&V=11&SessID=4555 coming the presentation on R600.

 

If you're that confident that something like 4xAA will be absolutely usable in coming games like Crysis or UT3 (Vista) in resolutions like 1600*1200, then by all means be my guest.

And your assumption about the supposed double bandwidth doesn't hold much merit either, since it takes a tad more than "just" bandwidth to overcome every possible other bottleneck that might occur.

(Again) if bandwidth alone would be the only defining factor for high resolution AA. But according to your claim above find one of today's taxing games and show me where a R580 can use 6xAA and end up with similar or higher performance than a G71 with just 4xAA. And yes the X1950XTX has a lot more bandwidth than G71 too.

 

Why couldn't they add hybrid Super-/Multisampling modes if they'd want to? Granted it wouldn't have to be the exact same algorithm as on Crossfire, but 2xSSAA wouldn't be that much of a problem. Besides I'd be more than glad if they did since it would put some pressure on NV to bring the hybrid modes back for G8x LOL

 

Sorry for my poor english...

I think SSAA SuperAA(CF) don't work with non stardard framebuffer formats... maybe the 'blend/composition' operation don't work in fp16 applications or even 10:10:10:2 fb format (like ToyShop or Andy shadow demo).

SSAA SuperAA gives horribly results with determined post-effects in applications, like NFS:Carbon, 3dmark05... CF SSAA gives a very strong blur effect (soaped!)... if you disable post-effects, the SSAA works good (with a minimum soft blur side-effect).

SSAA SuperAA works flawlessly in HL2:LC... incredible and perfect IQ...

'Normal' SSAA (like 8XS from GF7) don't give strange results... Works ok (and slow) in any application (but don't work with non stardand framebuffer formats too).

I think R600 has horsepower to make perfect mixed SSAA modes.
[SSAA mode working in SQR(2) X (h X v)]. Maybe using AVIVO engine to make downscaling operation.

I don't think anyone is saying Super-AA literally, meaning identical to how CrossFire offers these modes. What would be nice if single R-600 solutions could have the IQ flexible settings of x8, x10, x12, x14 AA to improve immersion.

 

Thats what i meant.

 

Drool

 

Hmmm, strange they would use the R600, just cause nvidia has been on the boxes of both BF2 and BF2142. Still be great to see thou!!

 

And this makes it strange.. how? It's BF"3", not BF2, not the first time company X uses hardware Y for game A and hardware Z for game B

 

300 watts

Crossfire would need 600 watts. I hope that's not true. I would bet most people would need a new power supply.

 

It's very unlikely to be true. Info from AMD's R600 demo event say that it's going to be 200w.

 

Yeah this power consumption thing is way overhyped and way overblown. They probably wanted more of a cushion than 225W provides for overclocking - I'm sure stock R600's will be perfectly fine with dual 6-pins.

 

man, nothing new today....

 

I would say anything above IQ x10 AA is plenty enough, because you will not notice any differentness anyway if you playing fast movement games at high resolution.

 

Wow, you said something I actually kind of agree with.

 

You comparing from the past ?

Interesting little comment on performance I saw posted.

 

Oh oh.....so Nvidia is holding back progress again eh
