1. "One of the guesses is that both GPU suppliers wait for GDDR3 to arrive."

I guess for GDRR3 you mean GDDR5

2. "...wait for GDDR3 to arrive..." is history repeating itself

3. Why not pour some money into smaller fabing (45, 32...etc...) and use that smaller sized transistors, less heat and power consumption to produce a 130523510000000GTX ULTRA MEGA-103314GB GDDR102140 in 2401 with 129 shaders!!!!!!!!!!!!!! OMG!


....laugh.

because they probably know THEIR needs, bottlenecks and how to overcome them BETTER THAN YOU DO.

Also, minimizing the transistors sizes and redeveloping fabs is moving in parallel with new releases, so they are not missing anything you thought they are.

4. Crysis clearly showed that some games are CPU bound, so this article is not completely true.

CPUs are also a bottleneck, and single core solutions haven't progressed that much in the last 1,5 years.

Crysis is a gaming crisis, one should never base his conclusions/estimations on such a game EVER.

well, single core solutions are becoming useless whenever time passes by, software developers should be the one taking advantage of multi cores to significantly increase performance. A developed single core developed solution might give you a 30% advantage, but with intel quads surfing around for a while now, a multi core developed solution can easily boost your performance till 75-80%.

5. This is a very long article to inform us that:

"ATi/Nvidia MIGHT be going with GDDR5 instead of 512-bit memory interface to lower their costs, widen their variates and improve their memory bandwidth, hence improving their performance"

This is good news actually, but the MIGHT part makes it totally useless and just a way to pass your time. "Like my posts all over the internet "

6. GDDR3 @ 384bit wide and 2.2ghz is not going to be dramatically slower than GDDR5 @ 256bit wide and 2.5ghz as announced by Qimonda @ IDF.

So a bit of caution in predicting miracles, because the real results are likely to be not nearly so impressive.

7. GeForce 8 supports gDDR4.

What does the 8800ultra use?

The Ultra uses GDDR3.
