NVIDIA Preparing GT300 Graphics Processor?
Hardspell reports that NVIDIA may have cancelled working on the G200b (the 55nm version of GT200). Details on this new DirectX 10.1 graphics processor trickled in, it has 384 shader units, uses a 45nm fabrication process and incorporates 1 GB of GDDR5 memory at 4.00 GHz (effective) while the core could be clocked at 800 MHz with a 2.00 GHz shader domain. NVIDIA hopes to take on the R700 and its successor which unreliable sources claim to be based on the Super-RV770.

Nvidia really has to redesign their graphics chips. ATI did so with R600 and now it's paying off.
1- GTX280 doe not compete with RV770, it's well above. Also in no way it's double as big. 1.4 vs. 1 billion transistor. 40% difference.
2- The card that directly competes, GTX 260 has 25% less resources then GTX 280. Would have been a "native" chip it'd have 1.1 billion transistors. RV770 has 1 billion. We could reverse your sentence and say Ati required 1 billion transistor chip to compete with Nvidia's 700 million chip... << 40% difference.
3- Nvidia cards have more ROPs, it contributes to size and as of now not to performance but it shows off where it's needed, very few cases, granted. No released game uses the power because before GT200, there was no card capable of that much (G80 does not count because it was to early: 7900 and X1900 and lower cards had to be taken into account). Games are optimized for 16 ROPs. If games start using that power or not is out of the question, but it does depend on the definition of efficiency you use.
second problem for nvidia is 45nm tech fab, who will make 45nm chps? INTEL? i think not, nvidia is transfering chips from 65nm to 55nm, while ATI is already on 55 for a time, next step is 40nm at TMSC
I'm looking at size of chip vs. performance. I don't care about chip potential. Remember that the FX 5200- 5900 were complicated but unbalanced. Even though they had much potential power, the series never saw that potential.
ATI's chip is far smaller than Nvidia's and it produces performance competitive to the GTX 260. There is no way that you can say that the 260 is like a 280 with half the transistors.
G92 = 700 million transistors.
RV770 = 1 billion trnsistors.
GT200 = 1.4 billion transistors.
Now HD4850 competes with higher-end G92 as GTX 260 competes with higher-end RV770. High-end G92 can't "touch" high-end RV770 just as high-end RV770 can't "touch" high-end GT200. If your sentence is valid, mine is too.
EDIT: the othe thing I said is that if GTX260 was the high-end Nvidia, the native chip, the physical chip, it would only require 1.1 billion transistors as those are the number of them in use in GTX260.
That's what I said. I was pointing out it is pointless to compare GTX 260 to HD4870 (same performance) and say Nvidia needs 1.4 billion transistors to compete with Ati's 1 bilion transistor chip. All 1.4 b transistors are not used. When used (GTX280) the result is a up to 30% faster card, on some cases.
and sorry for my bad english :P
Each card nvidia sells is a huge gouge out of their pocket. I doubt nvidia could afford to drop prices much more. The amount they're losing seems to be more than the price of a PS3!
Imagine the price of a GTX 200 gx2 card if released right now. Sales would be horrible, even worse than the GTX 280 right now unless they sold it for not much more than a 4870x2 (Doubt they could afford that, REALLY doubt it) Your english isn't bad. :)
I have a hammer I can help users with troubled products : )
nvidia FX :nutkick: oh noes ATi has passed them again and there cards cant even keep up with midrange ATi cards haha
ATI rocks!!! never Nvidia again!!!!!!!!!
Id guess there chip costs about 130-150 to tap out, PCB costs about 40-50, ram costs about 60-70. So at worst case where looking @ 220 to produce the whole card, most likly about 180 to produce it for the 4850 and prolly around 250 because of GDDR5 for the 4870 so do they really make alot of money with there cards, this was a bid to gain marketshare not money
Supply and demand the more popular the item is prices sometimes go up and up..
