GeForce GTX 400 Series Clock Speeds and Other Details Surface
Exactly a week ahead of releasing its GeForce GTX 400 series accelerators, NVIDIA held meetings with the press discussing the company's newest technologies, including GeForce GTX 400 series. Some lesser known details about the GeForce GTX 480 and GeForce GTX 470 surfaced, among more known and established ones. To begin with, the GeForce GTX 480 is confirmed to have a CUDA core (shader core) count of 480. The GF100 core operates at 700 MHz, its shader domain at 1401 MHz, and the memory operates at 924 MHz (actual, 1848 MHz DDR, 3700 MHz effective). With a GDDR5 memory bus width of 384-bit, the effective memory bandwidth would be 173.4 GB/s.
The GeForce GTX 470, on the other hand, has 448 CUDA cores, clock speeds of 607 MHz core, 1215 MHz shader domain, and 837 MHz memory (actual, 1674 MHz DDR, 3348 MHz effective). With a GDDR5 memory bus width of 320-bit, the effective memory bandwidth would be 130.7 GB/s. While the GTX 480 has a board power of 295W, the GTX 470 has a board power of 225W. Another piece of information the source reveals is that internal testing by NVIDIA showed that the performance level to expect from the GeForce GTX 470 should be 5-10% higher than that of the ATI Radeon HD 5850. The GeForce GTX 480 should be expected to be just that much faster than the ATI Radeon HD 5870. It is also expected that the target price of the GeForce GTX 480 should be typically US $499, while the GTX 470 should go typically for US $349. Detailed reviews of the two should be up by this time, next week.

and i think 5950 will have lower TDP than 480
More than 5% of CUDA cores DOA!
Not very promising start:laugh:
I've seen *many* boxes and specification sheets that presented the GTX480 as an 512SP GPU. The full load power consumption is taken from the Quadro/FX line, where things are a bit exaggerated. The consumer variant won't see that number unless you really stress the cards out with a special GPCPU benchmark.
Anyway, since when is so much important how much power a videocard needs at this high-end level? Comparisons with the 5970 are fine, but that card will have CF scaling problems in a lot of games, while the GTX480 will not, since it's just one GPU. There will be some surprises.
As for the *just* 5-10% performance increase over the direct ATI competitors, it's not entirely correct. There are no such figures from real sources, they are invented, and the release drivers will paint a totally different picture if there is even some truth in it. I remember 4870 and 4890 being faster at one time then the GTX260+ and GTX275. That changed after a driver release.
Again, nobody is saying the 5870 is faster but certainly from a price performance hit, it definitely is the better buy. My big thought is can the GTX4xx series power down in idle? The old 200 series did to a good degree so can this beast? If not, i say with purity - it's a piece of steaming shit.
Why so?
A good card must perform well, be run at acceptable noise levels, not spew forth tremendous heat, not consume a tonne of power 24/7 and... be affordable. (which is why the 5970 is not a good card - it's too frickin expensive. Bear in mind you can buy 2 5850's that cost nearly £100 less than most 5970's).
Nvidia lied again, they say the GTX 480 is the fastest Graphics card ever made, well what about the HD 5970 that puts circles around it :laugh:
*Btw, inside sources claim the heatpipes are filled with awesomesauce so cooling won't be a problem. :p

Point is ATI or Nvidia shoud not make claims like this, but we all know its for marketing.
There is fact, there is fiction and then there are marketing slides.
HD 5970 we know is Maximum board power: 294 Watts and Idle board power: 51 Watts. According to a few sites the 480 is 250W min and 300W max. This is new today.

And remember the most important thing in a piss-match.---Don't cross the streams!!!!!!
ATI has been very quiet the last few months, and there've been rumor of cherry picking and a possible 5890 long before the 5970s release. It wouldn't surprise me at all if ATI is merely biding their time on release . . . they tend to do that even more-so when they have other potential cards ready in waiting.
