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.

price will probably be $450 and sold out
unless these are OC'n monsters :roll:
it'd be nice if after all this time they released something that makes you wanna sell your 5870 for $275 just to make the move back to Nv.
this is not the case this time.
card will prolly be good for cuda aps + gaming but the price isnt justifiable.
"hey screw that red sports car, its 6 months old, buy this new green one.. it might cost more but it goes 5mph faster"
yeah good luck.
I bet these cards pack greater firepower if we could just keep the heat down..
EDIT: i think a 5870 @ 950/1300 will surely match the GTX480
ATI drivers are great at the moment, and the 10.3s bring some massive performance increase to the 5000 cards,whilst Nvidias have gone down hill dramatically, burnt out GPU's anyone..muhahaha..
I mean, come on...
2g HD 5850 5870 5890 anyone?
I must say I haven't had any problem with either ATI's or NV's drivers in the last 2 years or so...
But I have zero experience with modern day nvidia drivers, so I can't comment on them except for the overheating problems happening recently.
To add to the sports car analogy, I do like to mention that the new green car, that goes 5mph faster, also guzzles a lot more fuel, and has a large and heavy engine under the hood :)
These cards cost to much are to hot and draw way to much power compared to the ATI alternative. From this report I believe the 480 is going to draw more power then the dual GPU 5970.
:-)
if this is true the GTX480 is gonna be at least 20% faster than the GTX470 if its not bottle-necked by memory.
And of course you shared this ingenious fix with the rest of the world?
