I think you might have your dates mixed up a bit, and I'm not sure how the GTX400 series was 2 years late, but lets clear a few things up. The HD5850 will not turn 2 years old this October, it'll turn 1 year old this September. It was launched about a week after the HD5870 in late September of 2009. The GTX400 series was scheduled for release in the fourth quarter of 2009, but was delayed to the first quarter of 2010. This places its release almost exactly 6 months after that of the HD5800 series... not 2 years.
And a 6 month separation is certainly not unheard of in the history of GPU generations. In fact competing generations from ATI and Nvidia are rarely released within 1-2 months of each other. A 3-5 month separation is more the norm from what I can remember, with perhaps the only exceptions being the HD4000/GTX200 series and the x800/Geforce 6 series, at least in recent memory. In both of those generations ATI's GPU's were released about a month later then Nvidia's. But other then that, the HD2000 series came out almost exactly 6 months after the Geforce 8, and the x1000 series was released about 5 months after the Geforce 7, etc... In fact this is the first time I can remember Nvidia releasing a generation of GPU's after ATI.
[citation][nom]DSpider[/nom]It's a f*cked up thing. We're stuck on Intel platforms for SLI which is pretty bad for consumers if they hold the monopoly. Damn. I hope ATI rolls out the HD6xxx series soon.[/citation]
I'm interested to see what the HD6000 series brings to the table. It'll incorporate ATI's Southern Islands architecture, which will not be the entirely new architecture people have been waiting for. This is planned for the Northern Islands family of GPU's. It'll still be based on the Evergreen architecture inside the HD5000 series, which in turn is an evolution of the R600 found in the HD2000 series. It'll also incorporate the same or similar number of SP's as the previous generation at 1600, so in this way the two will be quite similar.
From what I've heard, one of the principle differences between Evergreen and Southern Islands will be in the area of tessellation. Southern Islands will incorporate a fixed function tessellator to boost tessellation performance, something that's seriously lacking in the HD5000 series. This idea is very similar to what's currently found in the GTX400 series. Many of these rumors seem logical and believable, considering Southern Islands will be manufactured on the same 40nm process as the HD5000 series. This doesn't give ATI many extra transistors to work with given their new business model, so we shouldn't see huge physical differences in core or cluster counts. It's rumored that the HD6000 series is set for release in the fourth quarter of 2010.
