The GT300/Fermi Thread

[annihilat0r]

uh why?

Because if a single + full Fermi is around 250W like being rumored, this means a dual fermi can pull only 50W faster than a single one, all the while being SLI. There's only a 40 percent overall difference between the 190W 5870 and the 300W 5970. So I figure it'll be much smaller in the case of GF100.

nvidia could just put 8165632 8-pin power connectors on the card so it can pull 1.21 gigawatts to deliver benchmarks scores before you even clicked start

ati deliberately chose to make their dual card <300w. nothing stops manufacturers from making cards that require more power

[FUD] Dual GF100 Fermi should be in April ohhhh myyyyy gawwd

OMG he's reposting his own "news".... http://www.fudzilla.com/content/view/17197/65/

isn't jedec standard mean they can only take 300w though?

spose they could just ignore the spec?

[BenchZowner]

Good job on the tags guys ( wait 'til Gautam or MM sees them ).
2nd... Fuad isn't pulling the dual GPU in April out of his a*s.

As for the performance fighting and ing... simply wait until the real reviews and the cards are out.
If you're looking for a new VGA, go out and buy one now. But wait, I don't think you needed to hear that from somebody else, you're in control of yourself hopefully

[ElSel10]

They can't be labeled as PCI-e compliant which would shut out a good deal of OEM business. Basically, you wouldn't find the cards in any pre-built PC because manufacturers would be too scared to use a card that is out of power spec and deal with any potential problems it would cause.

JEDEC has nothing to do with graphics cards.
PCI-sig is in charge of approving the PCI-Express BUS devices, but AFAIK you can release a 300W+ product.

[neliz]

if you google me you'll find me saying that a "395" will launch a "couple of weeks" after 360/380.. with the latest partner information, I decided to lower those expectation to H2. Don't put any money on a April Launch of the 395 (which was originally scheduled for March 2010 with the GTS parts in May.)

The product has to use less than 300W when it's offered to PCI-SIG for certification, they don't care less what your card uses when it OC's.

PCI-SIG consortium does stop manufacturers from making cards above 300w@stock or they don't get PCI-EX certification. I don't think Nvidia would forgo this just to make a faster card.

A dual GF100? Either nVidia is going for the total kill with a monster, or I have to make some major changes in my 50-60% calculations.

...Actually....

I got mine launch day. In the UK.

Go figure.

PS. the drivers were fine and still are

Really?
Where did you get it (and by card I mean 5850 or 5870, the 5700 series have been widely availible since November).
I am curious as it could be certain places have a good deal going with Ati which means I will keep my eye on them for the 2GB model if Fermi does not deliver

[zerazax]

Instead of doing an Ati and releasing the product early with insufficient drivers and poor availability (HD 58xx series cards did not come out in the UK until December/Last Week of November at the earliest and HD5970 cards are still not released here) nVidia will be releasing on mass in March with relatively mature drivers too (well I do say relatively, obviously there would still be the odd gremlin or two that you get with a new card for the first couple of months).

*insert facepalm pic*

I hope you're kidding. And the UK is hardly the entire world...

apparently this didn't hurt ati, their hd 4870 x2 is around 380w.

if you go to alienware and tell them they can have the fastest graphics card in the world, for a good price and some marketing development funds on top of that, but it's outside of some pci sig spec, do you think they will care?

Why would AMD go to such trouble keeping it below 300W then? Talking about 5970.

sorry I remeber someone saying it was JEDEC thats all

but thats cool, I know the standard is 300W but who cars about standards...

they are more... guidelines

[W1zzard]

which trouble? their 5870 is fairly low power consumption, by making the dual card like it is right now they leave space for a higher clocked product that is using better binned gpus. dont believe everything marketing tells you

there is/was no competition, so making the card faster gains you nothing

[annihilat0r]

What? Impossible. 4870x2 is 8+6 pin so it should have a max TDP of 300W. Yes, I know that you can pull more than 75W from a 6pin, but that's outside of its specifications and if it was 380W it would definitely be 8+8 pin.

Plus (total consumption)

I don't know where you are getting your information, but the TDP of the 4870X2 is 286W.

[W1zzard]

i measured 381w under load in furmark, card only, 273w peak 3dmark03 nature

test details here: http://www.techpowerup.com/reviews/H...0_IceQ/26.html

of course one could argue whether tdp includes stuff like furmark, as far as the spec is concerned i'd say it means "under no circumstances":
"Similarly, a PCI Express 300W Graphics add-in card is defined as a card that exceeds PCI Express
CEM 1.1 and PCI Express 150W 1.0 power delivery or thermal capability and, as such, consumes
greater than 225 W with support for up to 300 W inclusive."

oh, furmark then. That's another matter entirely and obviously doesn't enter into the TDP equation. So I think it's still safe to say that Nvidia can't make a card above 300W (outside of Furmark, but I think Furmark doesn't make geforce cards jump so much anyway)

it will this time around

[W1zzard]

check the gtx 295 in my results, jump is similar to 4870 x2 and above 300w

and obviously doesn't enter into the TDP equation

why obvious?

asus mars is 453w in furmark btw, 2x8 pin = 375w

[annihilat0r]

check the gtx 295 in my results, jump is similar to 4870 x2 and above 300w


why obvious?

because 4870x2 has got a PCI-EX certification and all sources I checked list its TDP at below 300W; and I am pretty sure PCI-SIG doesn't test the cards with Furmark.
