The GT300/Fermi Thread - Part 2!

Yeah, because developing a chip is what a few engineers do in their free time. AMD/NVIDIA designed RV870/GT300 to be a 40 nm part and TSMC didn't meet their claims. How can you blame the developer for that?

In the interview with ATI guys they explained that they had to make some major changes in their chip production process in order to get decent yields at TSMC (thanks to RV740). Nvidia didn't. Their fault.

Likewise, unless nVidia is keeping the best secret of all time, they will fail big time in mid-range and low-end (and thus total DX11 revenue). AMD's already saturated market for 6 months. Even if nVidia launched TODAY, they can't turn back time and make up so many months, and AMD can easily cut prices making market penetration very difficult.

EDIT: IMHO I dont think nVidia mid-range will launch in March, or even April.

They've been claiming their architecture is highly scalable. So we should see some mid-range parts at some point in time. But they are most certainly going to be late, since they are ALREADY late.

well, the fastest i heard of was the gigabyte card and that was cut down from 1ghz to 950 and now maybe even to 925, cause the latest rv870 chips dont clock that well anymore... probably a result of tsmc doing some weird things to try and improve yields...

the highest ln2 clocks i heard of were 1300... so i REALLY find it hard to believe 1150 stable on air... /

Around 1500 is the highest core clock on LN2. 1150 stable on air isn't actually impossible for quite a few cards... You just wouldn't bear the noise of the cooler.

Basically what I am saying is that if the GTX 480 bridges the performance gap between the HD 5870 and HD 5970, NVIDIA can initially price it quite high simply because there will be a sudden influx of GTX 480s into the market while HD 5970s are very rare. I'm not saying that is good for consumers but it would be good for NVIDIA's bottom line.

5970's availability isn't actually such a huge issue. You just have to spend a bit of time looking and you'll be able to buy a card.
But in really is far from the optimal purchase for anyone... Too long, too hot... Crossfire...
While GTX480 is a solid single card. Plus I'm sure it will be hyped at launch a lot so it will sell. Most high-end graphics cards usually sell... Power consumption / temperatures / price don't usually create an issue when talking about high-end graphics cards.

5890 has clocks 950/5,2 GHz

And I say there will be none. Source or it didn't happen!
