NVIDIA GeForce 6800 Ultra: The Next Step Forward

NV40 Under the Microscope
The NV40 chip itself is massive. Weighing in at a hefty 222 Million transistors, NVIDIA's newest GPU has more than three times the number of transistors as Intel's Northwood P4, and about 33% more transistors than the Pentium 4 EE. This die is droped onto a 40mm x 40mm flipchip BGA package.
NVIDIA doesn't publish their die size information, but we have been able to interpolate a little bit from the data we have available on their process information, and a very useful wafer shot.
As we can see, somewhere around 16 chips fit horizontally on the wafer, while they can squeeze in about 18 chips vertically. We know that NVIDIA uses a 130nm IBM process on 300mm wafers. We also know that the P4 EE is in the neighborhood of 250mm^2 in size. Doing the math indicates that the NV40 GPU is somewhere between 270mm^2 and 305mm^2. It is difficult to get a closer estimate because we don't know how much space is between each chip on the wafer (which also makes it hard to estimate waste per wafer).
Since we don't have information on yields either, it's hard to say how well NVIDIA will be making out on this GPU. Increasing the transistor count and die size will lower yields, and the retail value of cards based on NV40 will have the same price at release as when NV38 was released.
Of course, even if they don't end up making as much money as they want off of this card, throwing down the gauntlet and pushing everything as hard as they can will be worth it. After the GeForce FX series of cards failed to measure up to the hype (and the competition), NVIDIA has needed something to reestablish their position as performance leader in the industry. This industry can be brutal, and falling short twice is well nigh a death sentence.
But, all those transistors on such a big die must draw a lot of power right? Just how much juice do we need to feed this beast ...

Any ideas how the Non Ultra version will perform?segagenesis - Wednesday, April 14, 2004 - link
I cant agree with #45 more. People rush to judgement when its no secret that ATI will be coming out with thier goods very soon also. "Wow look this card is really fast!!! I cant believe it!" well this sounds like almost every other graphics card release from ATI or nVidia in the past. To me nVidia had better have come out with something good after ther lackluster Geforce FX 5800 wasnt anything terribly special. I used to like nVidia alot (heh my ti4600 still runs fine) but when it comes to looking for a new card, I'll pick whichever one is faster *and* has the features I want. If it wasnt for such turnoffs like the 2-slot design and now even 2 power connections required Im not sure I am ready to spend $500 just yet...Sorry if im obtuse but if ATI comes out with a part thats either equal (note the key term there) in performance or maybe even slightly slower... I'd go for ATI and thier better IQ that the Radeon 9700 series so impressed me on and made me wish for more out of my ti4600. That and a single slot/single power type design would probably put me in thier boat.
Fanboy ATI opinion? I've owned nVidia from the Riva TNT to the ti4600 and many in-between.

#42, the jump from the Ti4600 to the 9700Pro wasn't good for you? I woul dhave thought finally playable AA/AF was quite a jump.Personally, it seems less of a jump than the 4600 -> 9700.
And I will reserve judgement on how much of an accomplishment nVidia have made until I see what ATi release.
If it's of similar power, but maybe has 1 molex, or is a single slot solution, they will have accomplished more.
It's not just raw performance, we'll have to see how it all stacks up, and how long it takes to release the things!

Some site tested the 6800U on a 350W supply and it worked just fine.Myself, I think my Enermax 350W with its enhanced 12V rail will take it just fine as well.

Yeah, Nvidia did make one hell of an accomplishment. They just earned a lot of respect back from both fan clubs. You have to respect the development and research that went into this card and the end result turns out to be just as we anticipated if not more.I really don't know how anybody could pick a "club" when seeing hardware like this perform so well.
Im hoping to see the same results from ATI.
Just too bad they are some costly pieces of hardware ;)

nice to FINALLY see a universally quantifiable performance increase from one generation to the next.but the important thing is how it competes with the x800 from ati, not against older cards.
as for the power supply, i think the hardcore crowd that these are geared at already have more then enough power, and quite frankly i would be suprised if these woudln't work fine on a solid 350W from a reputable source (i.e. not your 350W ps for $10 from some 'special' sale).
They're being conservative knowing that many of the people have crappy power supplies and don't know better.

"Anyone know when it ships to retail stores?"http://www.eetimes.com/semi/news/showArticle.jhtml...
"GeForce 6800 Ultra and GeForce 6800 models, are currently shipping to add-in-card partners, OEMs, system builders and game developers. Retail graphics boards based on the GeForce 6800 models are scheduled for release in the next 45 days."

This has me a bit curious... maybe I didn't read close enough... but is this the 6800 or the 6800 Ultra?saechaka - Wednesday, April 14, 2004 - link
wow impressive. i really want one. wonder if it will run ok with my 380w powersupplyCygni - Wednesday, April 14, 2004 - link
Personally, im very impressed, and i havent had an Nvidia product in my main gaming rig since my Geforce256. The card may be huge, power hungry, hot, and loud (maybe), but that is some SERIOUS performance.How long has it been since Nvidia has had a top end card that DOUBLED the performance of the last top end card? Pretty awesome, I think. I dont have the money to pick one up, but hopefully the mid/low end gets some love from both ATI and Nvidia as well. The 9200/9600/5200/5600 dont really appeal to me... not enough of a performance leap over a $20 8500!
