Pentium 4 with Netburst architecture will hit 10ghz! ---- Intel

Nuff said.

We didnt say anything about performance... we said it should be substantially different from what we have now.

I really doubt G80 will be that substantially different, I think it'll be just a continuation of G70 with 32 pipes, and a really high clockspeed. My guess is the engineering is going into making a very complex GPU hit very high clock speeds. I think nVidia is going to try to hit early with DX10 GPUs and try to corner the market of average consumers because their computers won't be "vista ready," and let their high end cards drop in price before ATI releases R600 so when R600 comes nVidia will have a solid price advantage.

I read reports not long ago saying it wouldn't be unified Shader Architecture as it didn't provide enough benefit for that gen to consider.

That is what I have been thinking up until very recently. This(NV50) is nVidia's huge gamble- if this core fails the company will be in big trouble. This core entered into development prior to the launch of the NV30, it is supposed to be a bigger move for them then any prior part. I am not saying how it is going to turn out, but nV is pushing for it to be a R300 style force in the market. I had previously been under the impression that this wasn't going to hit until NV60, but apparently that isn't the case.

all gpus are worked on for 3-5 years. Both companies work on multiple gens at the ame time. 4 years is nothing specail. ATI during the x800 days said they were working 5 years ahead, starting the R&D process for the new chips down the line. Nvidia said they were 5 gens ahead at the same time. Either way, gpus arent desigend like sports titled, where after the title comes out, everyone rushed to start work again on a new one, trhey have multiple project teams working over many years with overlap of time between projects working for multiple gens at any given time. 4 years is pretty aveage.

We started architecting it about 4 years ago, and, you know, my best calculations have this investing $250M into it already, and by the time it launches as well as the entire product family, we will have invested about $500M in R&D."

Looks like the G80 will be one hell of a beast.

or a disaster like the DustBuster.

and they hyped the hell outta it before the 9700p put the smackdown.

we'll just have to 'wait and see'.

the 7900 didn't turn out so great as your expectations for it.

Some rumors I have heard indicate a 50% stock speed increase which is decent but nothing spectacular, but a design that greatly reduces power use and heat generation. This card may well not require a extra power connector from the PSU and may well offer the capability to run tandem in SLI with the current heat and power output of a single 7900GT. If true, this would be a positive direction for the technology rather then going with constant speed boosts and subsequent increased power draw in a linear curve.

i am curious . . . where do such rumours originate?

nVidia employees?

or people who "know" HW trends and are speculating?

obviously ATi is in "transition" with their Ring Bus and "Ultra-Threaded" architecture . . . and unified shaders . . . except forget the power draw . . . or noise - for now.

probably nVidia is heading in a similar direction but taking an entirely different way to get there [they have SLI as a goal for all of us so must consider power practicalities . . . . these types of revolutionary changes are each company's best guess as to what future games are like [and work with programmers to make it so].

if it is like r300, we will see performance increase steeply . . . also; if not then expect successive generations to be much more powerful.

I just dont see how it can be an extension of G70/71. Geforce 4 --> 5, Radeon 8500 --> 9700Pro both incorporated moves from DX8 to DX9. Each required total redesigns. With DX10 and SM4.0, it's hard to believe you can use anything current besides the ideas such as pixel shaders vertex shaders, but how they operate might be totally new.

all gpus are worked on for 3-5 years.

Not with a budget of half a billion dollars though
