Marchitecture at its finest

NVIDIA has the fastest single GPU for the desktop in the GTX 285, a 55nm die-shrunk version of its predecessor the GTX 280. However, ATI has been able to gain a larger market share due to aggressive pricing and ramping of smaller geometries.  This has led to price pressure on NVIDIA, especially in the performance mainstream segment.

NVIDIA's original GT200 chip -- which is used in the GTX 280 and GTX 260 -- is too big, too costly, and consumes too much power to be used effectively in a mobile solution. NVIDIA has already switched to TSMC's 55nm process from the baseline 65nm node to deal with these issues for the GTX 285, but it is still not suitable for the majority of laptop users. Battery life is too short, the cooling fan is too loud, and the cost is too much.

One solution was to begin manufacturing on the 40nm bulk process like ATI has done. According to our sources, NVIDIA's attempts to produce a die-shrunk 40nm GT200 chip were "disastrous at best". Design problems became evident, since the GT200 was originally designed for the 65nm node. Two shrinks in a row without a major redesign was just too much for NVIDIA, and our most recent information from Taiwan is that the first 40nm chips from NVIDIA will be in the GeForce 300 series.

Without a power efficient GT200 based GPU solution for the mobile or mainstream value markets, NVIDIA is rebranding the 55nm G92b chip yet again to meet these critical segments. The original 65nm G92 chip was used in the GeForce 8800 GT, but you can only do so much with an older design. The chip was respun as the G92b with a 55nm die shrink, and is currently used in the 9800 GTX+. All G92 chips are only DirectX 10 capable, and will not support the full feature set of DirectX 10.1 or DirectX 11 that will come with Windows 7.

The problem is that many consumers will pick up a GTX 280M or GTX 260M thinking that it is the same or similar to the GTX 280, when it is actually just a 9800 GTX+.

There is currently no GeForce 100 series for the desktop market, but Nvidia launched the GeForce GTS 160M and 150M for notebooks at the same time as the GTX280M and the GTX260M.

Uhh, the reason it's still an old, and I mean OLD - years old, 92(b) chip, IS BECAUSE NVIDIA ISN'T STUPID ENOUGH TO PUT THEIR KING CHIP ON A LOW END PRODUCT -
Unlike the red rooster cock crowing crew ATI - the billion dollar per year loss idiot crew - who slap their "OMG! they can really cut down NVidia with more cores per wafer !!!!" - TOP CHIP ON AN $80 SEGMENT CARD LIKE THE 4830....
Oh well, NVidia's barely reworked ("shrunk") 55nm G92 (heck G80 for that matter ! ) that is YEARS OLD ... still slaps away at ATI's "newest core!" in the 4850 (also not a top dollar contender, huh...) and WHOMPS the 4830 (that uses that $ saving ATI top core, huh...) ....
I guess the cocky red rooster has crowed a lot more than 3 times at this point....
And the answer is " I don't what you're talking about ?!? I don't know that man! "...
Yes, we know you don't uhh... know that myaaaaaannnn ...
Toke another one... bro !
