The GT300/Fermi Thread - Part 2!

[Leeghoofd]

26th of march is not now is it ? hold ya breath...

[LAMB OF GOD]

that glowing logo looks so hawt!!!
really cool !!!

[SkItZo]

Agreed

GTX470 will have this too?

[saaya]

I thought you were referring to the 1000Mhz driver leak? I'm not hostile. I just don't use as many emoticons as you do

well you def seem to prefer an antithesis over a thesis

625/1250/900...
those are really low gddr5 clocks...
5870 comes at 1200, thats 33% higher...
i wonder if nvidia clocked the mem that low to diferentiate the 470 and 480, or if they really cant clock higher...

[LordEC911]

for launch date are prepared 60 000 cards, in next weeks will be more!

You think Nvidia cranked out 60 000 cards in 2 months?
That number might be right for the total Ax allocation over the next few months.

And you have this info from whom... Charlie?

Well isn't that the basis for debate?

Or maybe more bandwidth won't help because the bottleneck is elsewhere. It could be any number of reasons and we will know soon enough. I'm amazed that nothing solid has leaked yet. Two weeks to go.

[saaya]

And you have this info from whom... Charlie?

no, charlie has nothing to do with this... you know, not everybody who questions a rumor that would be good news for nvidia has some connection to charlie... some people are really paranoid when it comes to charlie

it doesnt really make sense for nvidia to have that many parts at launch... they couldnt sell any cards for over half a year now, they just couldnt... and now all the sudden they have a big batch of cards for the launch? when even jensen said gf100 cards will only REALLY be available in the second half of this year? so there, nothing to do with charlie, simply based on what mr nvidia himself said a launch with 60k cards is unlikely...

Well isn't that the basis for debate?

what do you mean? a healthy balance of thesis and antithesis is usually the best imo... bull and bear...

yes, just like with rv870 that doesnt scale all that well with more bw either...

tsmc's public production rates for the 40nm process

if tsmc is only able to produce 80,000 wafers per quarter, i just can't see nvidia having 60,000 gf100 chips ready and waiting right now. availability will probably be scarce until tsmc ramps production further. i'm not doubting that there will be cards ready on the 26th, but good luck getting one for a reasonable price...

depends on the yields...
thats around 1K wafers per day...
lets say nvidia can use up half of tsmcs capacity, rather optimistic, but lets see where that takes us...

100% yield = 100 fermis per wafer (roughly) = 50k fermis per day
50% yield = 50 fermis per wafer = 25k fermis per day
25% yield = 25 fermis per wafer = 12K fermis per day
10% yield = 10 fermis per wafer = 5k fermis per day

even at 10% yields nvidia could stock 60k fermis in 2 weeks using their tsmc capacity for fermi only, or in 4 weeks using half of their allocated capacity.
so this actually makes sense and sounds very possible...
this only shows that its possible with tsmcs wafer output... if the yields would really be 10% then each chip would cost 500$ and it just wouldnt make sense for nvidia to produce a lot of chips, so while tsmc COULD supply nvidia with 60k chips in one month even at low yields, nvidia probably wouldnt do it.

provided the wafer output is correct... the amount of fermis available at launch depends entirely on nvidia... if they want, they can launch it with 60k available right away. if its less, then its most likely not tsmcs fault, but yields are so bad that it doesnt make sense for nvidia to produce a lot.

[Chickenfeed]

I sure hope the GDDR5 is at least 4000 and not merely 3600. 144GB/s is on the low side for a new card even if it isn't the top sku... And if the 275watt info is true, the 480 better be like a rabit out of a hat otherwise...

And lol at Charlie. You can totally tell that he is making fun by claiming he was wrong ( when infact more than anything it proves he was right... +/-5watts is nothing to fight about )

So it only takes one day for TSMC to get the order, cook the wafer, get it cut, test it, send it to Nvidia to test, Nvidia to get the kits to AIBs, and AIBs to get the cards manufactured, packed and shipped?
Hmmm... I guess we dont have a facepalm smiley.

Also, although we don't know the exact numbers of parked Ax wafers, those wafers have to last them until Bx is ready... which best case is end of Q2.

Both GTX 470/ 480 ES tested are downclocked versions, and they using an old version of drivers-for GTX 470/480.
The clocks will be a little higher( not 750 dream).... probably 675/1350/1100( GTX 470) and 650/1300/1000 GTX 480.
To much hAT(e)I on this thread....Ati fanboys forget their 2900XT dark age, and they forget their nightmare 8800GTX...
Both GTX 470/480 will be good cards...
Hopefuly GTX 460 will come in may and smash GTX 5770/5830/5850 at price/performance.

[SocketMan]

That looks like the HDMI (audio out) connector,anyone knows what it actually is?

Thanks VVV

I'll believe the ES/non final BIOS part.

Why would you figure the 480 would have a lower memory clock... If anything the memory clock will be at least the same, most likely more. The extra bit width helps but not that much.

As far as hate, I wouldn't go that far. We've just yet to see / hear anything that contridicts the direction things seem to be going. Anyways how are past gpu generations success or lack there of relavent? Yes the 2900XT sucked and yes the 8800GTX took the trash to the curb but what does that have to do with today? I don't care if Nvidia released an awesome product line in the past ( I owned a 8800gtx for a year and a half from launch week ) if they don't continue to do so.

In closing it would be nice if all of our pessimism could be greeted with a pleasent surprise is all.

loved the link saying oak ridge national lab doesnt want a fermi cluster....

DH claims that it has acquired information about GTX 480 and 470.

Says that GTX 480 is a 512SP part, and its TDP is.......................... 298W
GTX 470 is 225W.
Overclocked GTX 480 is 310W.


Even Charlie is saying 275W....

[Behemot]

2900XT

Initially yes, but than it was pretty much as GTS 640 MB, later sometimes between GTS 640 MB and GTX. But the power consumption was bad, it's true...

[***Deimos***]

Fermi = 225W (or 275W)
Not the end of the world!!

Probably while using some special GPGPU applications only.

Despite all the nay-saying, it IS a FIXABLE problem. Just look at progress G92 made just by switching PCB, or reduced power on higher clocked HD4890.

Charlie is just being ultra-paranoid. Architecture is no more broken than it was in X2900XT - and despite power management and Anti-aliasing bugs, that card still got great performance in many games, and was the basis for HD48xx.

In the end, when it launches, (just as the HD5xxx) the hype will evaporate to reveal pretty typical average looking video cards with double horsepower of old generation.

Totally agree...

soon nvidia will ask extra psu for graphic card only or go voodoo way with external adapter and after that .....
