nVidia GF7/ATI equivilant:WHEN?

So when will we see the next generation video cards from nVidia and ATI?

Stupid question:can an ATI card be used in SLI mode on an nForce4 SLI mobo that supports the feature??

no.. ATI is working on their own SLI implementation though..

next cycle is probably a refresh cycle.. then new tech
 
It doesn't look like ATI cards will be going SLI anytime soon.

The true next generation of cards (not just some slightly higher clocked versions of current cards) are to be released in the first half of 2005. Neither ATI of Nvidia has announced a specific month (or even quarter) yet.
 
ATI would probably dust off their MAXX technology rather than go with the sli route, they had implemented it in the core of radeon and radeon 8500 but never used it for desktop purposes, irrc, it was a multi million flight simulator that had a 32 gpus of the 8500 line, not sure if maxx was also in the core of the 9xxx series.
 
Damn, thats more than a year away!!!

Will we be getting an nVidea or ATI performance bump before that? (say Q1 or Q2 2005?)

1. NV50 was to be unveiled in 2005 but the project has been canned for nVidia for a variety of reasons (Longhorn being delayed, industry pace not keeping up with r&d efforts, r520 being a damn intimidating monster of a chip..) and what nVidia will do with their next release is in limbo. R520 will be a variation of the XBOX2 chip (R500) and considering MS will release XBOX2 H2/2005 or H1/2006, R520 should probably be out in Q4 2005 for the XMas season.

2. No, but ATI is finalizing a technology called ABR (?) that will enable their cards to run in parallel on PCI-Express systems without the need of an SLI bridge.

ATI is launching the R520 in May.

Argh...

NVIDIA has SLI (not to be confused with 3DFX's SLI).

ATI has AMR which stands for ATI Multi Rendering. The difference is that AMR doesn't require a cable to connect the cards together as they communicate entirely through the PCIe bus. AMR works with any compatible AMR card. It doesn't require the same card, for example, an X800 XL can be paired with an X850 XT PE. There aren't any details though on whether you can pair any of the current cards with a future card even though the description suggests so.

ATI's AMR only works on ATI RS480 and RS400 chipsets just like NVIDIA’s SLI works on their chip sets.


The R520 is based on the R3XX. The chip inside the XBOX2 is an early preview of the R600. Although its called the R500, ATI apparently wants to move away from pixel and vertex shaders to a unified model which is what we will be getting a taste of in the R500 apparently (and from the early specs of the GPU and what it can do, this definitely backs it up.) The R520 is based off the R3XX with SM3.0.

It is not a refresh, the R520 design is "based" off the R3XX.

NV50 aka GF7 is *rumored* to have been cancelled :lol


actually I doubt NV50 is really cancelled.

That may be and most likely is true. ATI is pushing and wants to move towards the uniform shading model (SM4.0) while NVIDIA doesn't. Since this will be coming with longhorn and the NV50 coming close within its launch, it makes sense it would be cancelled as the card would be rendered obsolete within less then a years time (epecially the refreshes, mainstream, and budget derivatives launched afterward). They would have to design a new GPU from the ground up with the SM4.0. It makes sense they cancelled the NV50 to instead start work on their next chip with the new Uniform Shading model (SM4.0) to have a whole line of GPU's ready in time for launch of Longhorn.

ATI has been vocal about unifying the VS and PS while NVIDIA has been vocal it is not interested. Granted, the specs for SM4.0 aren't finalized or finished but it looks like NVIDIA may have given in and started on a new GPU design.
 
yeah R520 and R500 are very different VPUs

R520 is an extention of the R3XX, like the R420 and R480 are.

R500 in Xbox2 is based on the old R400 that got canned, and should indeed be a preview of the R600 (assuming R600 isnt also canned)

R520 should be SM3.0+

R500 should be SM3.0++ or close to SM4.0

If these two chips do not share the same architecture I'll eat my hat.


The R520 deisgn will be based off of the R3XX line. The R500 is the basis of R600 depending on the finalized SM4.0 spec.
