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.

you guys should do some reseach before bashing the hell out of Nvidia: http://www.tgdaily.com/content/view/39482/135/

This was posted September 25th so there was plently of time to expect these changes.

Chicago (IL) – Nvidia will be dropping the 8000- and 9000-series names, industry sources suggest.

Following a recent announcement that the company would lay off about 7% of its staff, it seems that Nvidia is busy bringing the company back on track. Rumor has it that the company will be announcing additional graphics cards in the GT200 series on October 15. Coinciding with the product launch, Nvidia is expected to depart from its sequence numbering system of the 8000- and 9000-series and transition to a system that is in line with the GT200 series.

Industry sources told TG Daily that while the 8000 series is being phased out, all 55 nm 9000-series GPUs will carry a G100-series name. By the end of 2008, Nvidia will be offering today’s 9000 series as G100, GT120, GT130, GT140 and GT150 models.

When the 2009 45 nm GPUs arrive, which seems to be the case around Q1 or Q2, Nvidia will have fully transitioned to the new branding structure: Enthusiast GPUs will be integrated into the GTX200-series, performance GPUs into the GT200-series, mainstream GPUs into the GS200-series and entry-level products into the G200-series.

The new branding should clear up some of the confusion in Nvidia’s product lineup today.
