The G80 currently sits at 420mm². Time for a diet?

Here's a real short news bit from the guys over at DigiTimes:

"Nvidia has placed urgent orders with Taiwan Semiconductor Manufacturing Company (TSMC) for GeForce 8000 GTX and GTS series chips as demand for graphics cards supporting DirectX 10 is picking up, according to market sources, as cited by the Chinese-language Commercial Times.

Monthly shipments for the urgent orders, which will begin in March, will be equivalent to 3,000-4,000 12-inch wafers using 80nm technology, the sources were cited as saying. "


Since the chips are being migrated to 80nm, we can expect some pretty hefty changes in the way the 8800 series of cards are sold. As well, the change should have some particularly beneficial performance enhancements.

First of all, the die shrink should reduce the core's surface area from 420mm² to a bit under 380mm² if the process shrink involves perfect scaling. Power consumption will also drop due to the shorter distances between transistor gates. The two of these things combined mean that we should see some lower temperatures from the next round of G80s, which would be a blessing and a half - current models are not unknown to hit a blistering 90C under load.

The second blessing will come with cost - the die shrink means that there will be quite a few more chips per wafer. On the 90nm process, NVIDIA gets about 80 chips gross (meaning before defective chips are thrown out) out of each wafer. The move down to 80nm should increase this turnout to roughly 90 chips, a 12.5% increase. The increased yield will allow NVIDIA to drop the cost of the chips a bit, which we will hopefully see filter into the marketplace sooner than later.

As mentioned, the order expects that the chips themselves should be in production by March. Could we be seeing an April or May price drop for the G80? That would put it just behind (but still close to) the tentative March 2007 release date of ATI's R600.

We'll keep you informed as we know more. In the meantime, let us know your thoughts in our forums.

Finally! Will it go below 185W?
Quote HugoB 16th January 2007, 18:12
Die shrink is always good, with this and PCIe 2.0 at about the same time, we may finally be able to loose those power connectors, which in turn means less damned power regulation circuitry on the card, which means we might be able to fit the damned things inside a case!

Look at the current VAT free prices if you want an indication od the price drops we can expect and it isn't likely to be far wrong imo.

i am waiting for the 8600..... cheaper and DX10 and it is powerful....

Probably not, Knowing nvidia they will find a way to **** things up.

Can I say ****?




P.S. I'm back from being ban for a year.

Hmmm...when you say that, I hope you remember to group NVidia and ATI (or, the ATI branch of AMD) in that same group. IIRC, rumor has it that ATI's R600 GPU is going to debut with a power draw even higher than NVidia's regular 8800GTX.

I don't think either GPU company intends to work too hard on meeting lower power requirements any time soon...

PS: welcome back from your ban...based on your use of ****'s, I'm guessing you were banned for language?

Anyway I'm thinking the 80nm versions of the G80 is going to be the G81's or 8900's

I hope so , that way i can immediatly buy one of those :D
Otherwise it'l be like when i had mt 7800 and the 7900 came out , i just had to have one :p

It's rumor that the r600 has an updated frame buffer, that's include into the xbox 360 gpu.

I really don't think you can point the finger at Nvidia only. As mentioned above, ATI are just as guilty of upping the power reqs of gpu's to extraordinary levels.

I mean, we now have 2000 watt power supplies! Madness... running two machines are home and a laptop, I have noticed my electric bills higher this year than last.

/sigh -- I want mini components, not massive!

the price of fuel has gone up, though (at least in the UK)

The price of oil is rising to $50 a barrel soon, it's a psychological price point however, it's relatively fine with inflation.

Not sure why that has anything todo with power consumption though Tim?

I think his point was that the rising fuel prices at domestic supply level mean that, even if your consumption remains static, you will see an increase in the bill, which may go some way to explaining mmorgue's situation - it isn't just that he's using more power, the power he uses is also more expensive.

Interestingly, although domestic prices have shot through the roof, oil prices have actually dipped recently. We should see a knock-on in a few months, because suppliers buy their stock on the wholesale market in blocks a fair few months in advance.

But even though fuel prices have gone up, using 185W compared to the old values is going to hurt a lot more.

True, but remember 185W is the absolute max power draw of an 8800GTX at stock speeds. In normal Windows use it won't be using anything like that, and even while gaming it will only be if you really stress the card that it will hit its peak. 1 kWh at the moment maybe costs 15p tops, so running a PC that eats say 1/3 of a kilowatt will cost you 5p an hour - not bad value for your gaming entertainment fun IMHO. Even a total beast of an overclocked PC will struggle to burn through 500 Watts on average while gaming, so even that is just 7.5p per hour.

Why are they producing such massive power supplies if there's no demand for it? If 2KW PSUs weren't required for some systems there would be 0 need for them and they wouldn't be made.

First off, people love conspicuous excess. It's a nice boast in geek circles to be able to say "I've got a 2kW PSU", even though it is total overkill.

I defy you to spec up a desktop system that will tax even a 1kW PSU. Even with an overclocked QX6700 (at 130W stock, you might push that up to 200W with overclocking), a couple of 8800GTX in Sli (again, with overclocking, you might push the 185W stock power draw up to a max of say 250W. Multiply by two and you've got 500W). The rest of your components, assuming a couple of Raptor X in RAID 0, a couple of big drives for storage, two optical drives, a sound card etc., MIGHT just make up another 100W peak. IF you could find a way to push it all to the max at the same time (something like the bit-tech stress test, nothing you would actually DO day to day), you might be able to push 800W.

Now scale back to what 'normal' enthusiasts are using - a high spec C2D processor, overclocked drawing ~100W, a single high end graphics card drawing maybe 200W, a couple of drives etc., and you're looking at comfortably within 500W.
Quote DougEdey 17th January 2007, 12:17
I agree with you there, but I go back to my original question: Will NVIDIA reduce the power draw with smaller G80s? the 65nm process for CPUs already reduces heat output massively which has to be related to the amount of power it draws and thus reduces the sizes of fans required to cool them (look at X360V2 or AMDs EE range).

So with the current trend of G80 being Max 185W will that rating drop? It will still affect my overall systems power consumption if I don't use all that 185W because idle power draw will still be quite a lot due to inefficiency.

Will the 80nm also lead to a smaller PCB due to higher efficiency and a smaller cooler needed?

So essentially (after asking questions like the above to myself) What will the new G80s TDP be?

Hmm...I'm not sure how the world oil market works...but here in the US, we've been hearing that oil is DOWN near $50 a barrel recently since the midwest is getting much warmer winter weather than usual (and thus need less "heating oil", so demand is low). I can remember some months back (perhaps over the summer) when the oil prices were listed at over $70/barrel on the news here...

wow, i had no idea that 8800s run at 90*C... thats rediculous..

my x1950xtx is a hot gpu, not going over about 75*C on stock, but 90 is just bad... lol

I reckon the 2kW PSUs are for things like QuadFX with a pair of R600's...
