FERMI Benchmarked?

[LordEC911]

This.

Plus, what's going to be Fermi's TDP? Any info on that?

300w max. 6+8pin.
I am expecting around 225-240w, since whatever they are planning for the dual card needs to be down around ~160-170w TDP.

Well if you take it in the context of gt200 on a level of say P4 performance and gt300 being a jump of say i7 level of performance then in that context I guess things could be possible & interesting but seemingly unlikely.

Considering it is being touted as a new architecture there could be many more tweaks than what we've heard about with only the fermi tesla info we have now.

[LinkinParkBoy]

GTX 360 = 320bus x 4 = 1280MB
GTX 380 = 384bus x 4 = 1536Mb

?

I think its very plausible, but the source is dubious. So I agree with anyone professional and take this with a huge grain of salt.

Honestly everyone expected and believed the 5870 was going to have perfect crossfire scaling, I don't think a single person on this board doubted that. I though it was going to have perfect CF scaling and when the card came out and it didn't, I was let down and didn't want to purchase a 58xx anymore. When the 5970 came out, I was even more let down because from AMD slides, I was expecting significantly better performance. But the increase in price and decrease in performance, really made me not want to buy the card anymore.

When benchmarks essentially claim the same thing, but from NV, people are claiming it is too fast, it impossible, even when fermi specs, indicate, it has more than twice the shaders, those shaders are 16% faster and on top of this, its a new architecture.

So why do people believe it when it comes to AMD perfect CF scaling is possible, but from NV, it can't be, its impossible, when specs and a change in architecture indicate the NV scenario is more likely to be true?

The reason (IMO) is ego.

[NaMcO]

Nice try nvidia lol

Don't be scared, if it's true you can always buy one...

[clayton]

I really hope these are real! >=)

Heres the original thread.

x-fire scaling is to do with drivers, why did you and you say other people believe differently lol, and tbh for what the 5970 its less then twice a 5870... so its not too bad,

oh and logic... is stopping people saying stuff about nvidia's new arch etc..

x-fire/sli is just driver optimizations and some other crap.. its only limited pretty much by software unlike actual hardware of a new architecture we have not many actual details on

225w max. 6+8pin.

300w will be max 8 + 8, then it's out of pcie spec .. although theres some information going around about the card actually which means it can "bypass" this limit by other means..

Same, but I hope they don't go mad on the price.

If they're over 450 euro each they'll be worth more than the rest of the parts for a pc.

People who believed in perfect crossfire scaling were fools*. CF/SLI will never scale perfectly. Hell, even simply doubling the number of processing units on die will not have perfect scaling. Look up Amdahl's law if you are wondering why.



*just like the people putting too much stock in these slides.

[NaMcO]

I don't expect the top of the range card to be LESS than 550 euro. I simply don't believe it, but who knows

[skugpezz]

Don't be scared, if it's true you can always buy one...

lol it is scary if it is really that fast

[N19h7m4r3]

Yes, probably just wishfull thinking on my part. Let us hope it's shorter than the
5970 at least.

[Carfax]

Man, I really hope it's true, just so I can see "certain people" around here eat a healthy dose of crow

[Jowy Atreides]

I hope it's true. 2nd hand 5850 prices would get crushed.

Even if fermi is this fast, the 5 series are still freaking monster performers.

[tajoh111]

Christ I forgot to say one thing in my original post. People were expecting 4890 performance x 2. Basically 4890 CF with perfect scaling in the 5870.

[Solus Corvus]

Speak for yourself. Maybe you set your own expectations too high - a similar thing seems to be happening with Fermi too.

[Tim]

I think this is actually quite plausible, nVidia already said it's the biggest architectural leap since the G80, and the G80 was pretty groundbreaking in performance.

I can see this turning out to be true. Now this must be with silicon rev. A2, because AFAIK, A3 isn't back yet. So it might even get better.

What the hell is this supposed to mean?

[kakihot]

just i know "nvidia is very very great Company" with many money

[v_rr]

Results seem plausible, more than doubled performance compared to GTX285.

That's wishfull thinking, they barely got 66% of the targeted clocks with A2 and you want them to beat a beast like 5970 so easily? with a single gpu? with just 220W TDP?

G80 was such a leap forward because they switched from the old architectures to the new fully programable architecture for DX 10. I doubt we will ever see such an increase because DX11 does not require such big changes in architecture.

Though it would be great to have such a great performance out of Fermi. But i don't think it will, to many problems till now (exactly like the Radeon 2900 series) to actually think it will be so great.

? How many money not I know.

Go back to the original thread for the 5870, everyone thought we were going to get perfect 4890x2 scaling but on a single gpu.

[damtachoa]

This is absolutely BS. 225w outperforms 300w? Then ATI must close their manufacture and file bankruptcy.

[LordEC911]

300w will be max 8 + 8, then it's out of pcie spec .. although theres some information going around about the card actually which means it can "bypass" this limit by other means..

Whoops, thanks for the correction.
8+8pin = 375w max and won't be seen on the reference boards. I have a feeling we will eventually see AIBs add it on there though once they are able to do custom designs.

Go back to the original thread for the 5870, everyone thought we were going to get perfect 4890x2 scaling but on a single gpu.

Not really, that was optimism mixed with the synthetic bench results...
At least no one said something like, "it will beat the last generation dual card by at least 30%." That one there is just a classic.
