IF (very big if) ATi can get the same kind of performance leap from their new tech card, it could very well be a beast of a card. If the NV50 or whatever is a refresh of the NV40, it *could* be trouble for NV.
Saying r420 is two year old tech is like saying Prescott is 12 year old tech.
What is r420? Yes it's r300 based, but they've doubled the pipelines, added more vertex/pixel units, changed supported features...the same way that Intel's newest CPUs are just 486/DX's with a longer pipeline, faster clockspeeds, larger caches, and support for new instruction sets. They're both still x86 processors.
This was one of the stupidest arguments I've ever heard. If you take two year old tech, shrink it to provide more efficient power consumption and heat dissipation, and then double the numer of pipelines and double the clockspeeds, YES, it SHOULD keep up with modern hardware with the same number of pipes a slower clocks....If I could overclock an old 486/DX to 75Ghz and add new cache and instruction support, you'd be amazed at how well it decimates an Athlon 64...
Seriously, please think before posting.
Touchez! Very good points - calling the X800 series "two year old tech" is pretty nonsensical. It's new technology, just without SM3 support. If it had SM3, it would all of a sudden be this magical "brand new, innovative" design.
ATI went 'safe' with the X800 series and as a side benefit got higher clock speeds out of their chips. Nvidia went all new (as they had to - the FX5800/FX5900 series had PS 2.0 deficiencies). Now, Nvidia is the market leader with the newest tech, kind of like when ATI sprung out the 9700 Pro and caught their competitors with their pants down. Except the difference from PS 1.0 to 2.0 is bigger than PS 2.0 to SM 3.0 (or at least what we've seen so far).
With that said, it seems FAR easier for developers to add SM 3.0 support than going from PS 1.0 (1.1 - 1.4) to 2.0, so SM 3.0 support is a nice feature to have.
That said - the 420 IS a direct decendent of the r300/350/360 - it is EXPANDED and REworked, but not "new" like the nV40 is "new".
r500 will be "newer" (w/SM 3.0 support) and r600 BRAND new (a completely new ati design team).
