Beyond3D's GT200 GPU and Architecture Analysis

It will work on all G92 cards with a modified driver. The G80 I'm not so sure about yet. Most of this is a question of time/QA.

You won't even have to do that. A simple manual install via the device manager is enough.
 
Read somewhere, but source seems not to be avaible now:
GTX 250: 160SP/48TMU/24ROP, 768MB/384-Bit, G200-90, PCB P667
GTX 270: GTX 280 with lower frequency, G200B-300

Start should be soon and prices should be comparable to new HD4800.

55nm? already?

That being said, is the GTX moniker equivalent to AMD's HD 4850 moniker? So no more GTs, GS, etc.

160SP it's simply not possible with the current NV architecture. 144SP or 168SP. Actually, judging from the reviews of HD4870, I think that the only thing that NV really needs right now is 55nm parts, to speed up clocks and recover some missing performance pieces, and to cut costs.
They need something to match HD4870 at its price point, not something below, where there is still plenty of offerings...
Anyway I still think that a 144SP gpu is possible, because they thought that such a card could be enough to match a HD4870. Bad guess, I suppose. :LOL:

GeForce GTX = Enthusiast
GeForce GT = High-end performance
GeForce GS = Mid-range performance (tentative)
GeForce G = Entry (IGP products and sharing)

GTX= 260 through 290
GT= 230 through 250
GS= 210 through 220
G= 201 through 209

I'll believe that when somebody explains how a 6 cluster part can have 160 SPs ;)

Indeed, original source seems INQ, but the article is not foundable, only a to German machine translation in a Chinese forum. :LOL:

I would think it could be a 7 Cluster part: 56TMU/168SPs with GTX 260 clocks, what should end up slightly over HD4850.

Thats really excellent. Best product naming scheme in ages.
 
GTX260 $349
GTX280 drops to $449~499?
GTX290 $649?

I wish they drop the ridiculous price tag for the GTX280s though. On a side note, just how much can they reduce the price of GTX260 seeing as the HD4870 is faster.
 
The GTX 280 and GTX 260 really need to be transitioned to 55nm with higher clocks to be competitive in price/performance ratio.

Also, hopefully NVIDIA will prepare for the fact that AMD can potentially release two high end cards, "4850 X2" in the $400-$500 range, and "4870 X2" in the $500-$600 range.

I don't think two AMD X2 would make much sense given it's the same chip underneath. Yeah, its possible, but I don't know that I see it when traditional crossfire can fill in the holes.

It would be just like comparing 4850 Xfire for $400 vs 4870 Xfire for $600, but with two dies on one card. There is still a big enough difference in price and performance between 4870, 4850 Xfire, and 4870 Xfire that it makes sense to sell a 4850 X2 to fill another high end price point with the 4870 X2. So the 4870 X2 would have the highest performance and highest price ($500-$600 range), while the 4850 X2 would have higher performance and price compared to a single 4870. The Xfire systems with two separate cards would then be marketed as an upgrade path for anybody further down the road.

So the lineup would look like this:

$599 4890 1024 MB GDDR5 (= "4870 X2")
$449 4880 1024 MB GDDR3 (= "4850 X2")
$299 4870 512 MB GDDR5
$199 4850 512 MB GDDR3

with each card having the ability to be used in CrossfireX.

Most people with money who are looking at the ultra high end segment would prefer having one multi die card vs two single die cards, assuming that price and performance is similar between the two. Also, it would be much more palatable to use "4850 X2" in CrossfireX than having to buy four 4850 in a quad CrossfireX setup.
