The official GT300/Fermi Thread

[Solus Corvus]

I'm not convinced. We'll all find out when it's released though.

If it was just a doubling of resources without major architecture changes then I would say that the average performance would would be LESS then 2x the previous gen. You can't expect linear scaling.

But I'm taking into account that there are architecture changes. Most of the changes don't sound like they would make much, if any, performance difference in games. But perhaps the efficiency improvements will help make the most of the resources available. But without major changes to the shaders and arch I don't see how you'd get more then 2.13x scaling, except in corner cases.

Nvidia has already indicated that there will be a dual GPU version of the GT300.

Any timeframe? Will it launch with/near the other cards, or will we have to wait for a shrink like the 295?

Number of transistors is not what determines heat output, that would be the TDP, which will be similar to the GTX285, so that really won't be much of an issue. Nvidia won't let that happen, and based on performance of the 5870, and knowing the specs of GT300, I believe it is pretty clear the 380 will be faster, which nvidia has already confirmed.

You know what I mean, of course 10 billion 1 mhz transistors wouldn't be very hard to cool.

A TDP near the GTX285 would be very much of an issue. How many NV cards are on the market with 2 full speed, not cut down GTX285 cores, even now? 1000? To make the standard 295 they had to cut the number of shaders and the speed. To make the 395 they will probably have to make even deeper cuts to be able to fit it in the power/TDP envelope.

Nvidia didn't confirm anything, they said they "believe" it will be faster in games. And I'm not going to take their word for it, benchmarks will tell us the truth.

I expect the performance to be MORE than two 285 in high-res 8xAA.

Why?
