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.

Which games will run acceptably using the DX10.1 features on a standard laptop? Hell, the number of DX10.1 titles is minimal at best making it even less likely you'll ever actually use the 'features' 10.1 offers over 10.


That's his choice as a consumer, However there have been a few cases in past history where buying a chip with superior performance but with a feature set that is a generation behind would mean that the card would be useless for newer generation games despite having ample enough processing power to do so.

A few cases where this happened was with the x8xx series of GPU's from ATI, where SM3 only games wouldn't run on the GPU's. - Games like Bioshock.
What happened? The community gets together and re-writes the games shader packages (Shader Shock).

Or hows about when TnL became mainstream which left out the bulk of Intel IGP's, The Radeon VE/LE, The Voodoo 4 and 5 GPU's even though they were performance wise capable of running the games?

Or when games started needing Pixel Shaders and the Geforce 4 MX440 being one of the best selling GPU's of all time was in-capable of running such games? - Despite being faster than the Geforce FX5200?

Performance can always be increased by reducing the games quality, driver tweaking, overclocking, but there is only so much you can do with feature sets not being available, not everyone has the cash or even desire to upgrade every 12 months as soon as something better comes along.

Yep, I can't run rainbow six vegas 2 on my older computer because it has an x800 gto.
