Report: Nvidia GTX 480 to Have Disabled Cores
It would be interesting if those cores could be re-enabled.
Nvidia's road to bringing the GF100 to market has been a bumpy one that will finally reach its first stop this Friday March 26 with the launch of the GeForce GTX 480 and GTX 470.
According to a story from Digitimes, which Nvidia refused to comment on, TSMC's 40nm yield is currently still under 50 percent which could mean that some GPUs are coming out less than perfect.
Rather than completely toss out the chip, Nvidia could disable the bad cores. Digitimes says that this resulted in a lower core count than the original 512; the GeForce GTX 480 will only have 480 cores and GTX 470 only 448, the website reported.

So not only is Fermi late, but now they are ounting sub-standard GPU's.
Fair enough this sort of thing has gone on for years in CPU's, but it aint helping Nvidia's image in the slightest.
Glad i got my x-fire 5850's
interesting... will you be able to enable them, as with AMD cpu's which had disabled cores? and the 10% better then ATI 5xxx was tested with those cores enabled?
Doubtful, as ATi have been purposefully disabling SIMDs whether they were faulty or not, but in a manner so that you couldn't unlock them.

ATI cards have disabled parts too due to yield issues - what do you think the main difference is between your 5850 and a 5870?
post rationalisation aside, I'll be waiting to see the figures and prices before I make my DX11 purchase
I think it would be interesting if those cores could be unlocked - I'm curious how long the card would last before it caught fire.
The ATi cores are physically cut by laser to disable them. All 5xxx cards are all essentially the same chip with certain shaders etc disabled.
It seems that the Fermi chips have faulty cores which have been disabled, which is a different thing altogether. I'm sure their yields will improve over time and they'll release the 485 with the full 512 cores enabled
And there were people telling charlie (semiaccurate to shut up with the acusations) and so far all he said are true
semiaccurate charlie gets a lot of flak because he suggests and theorises with seemingly nothing more than opinion and a passing comment from his "contacts" a good 6 months before anybody else even thinks about something. as a result he's passed off as a fanboi or just too caustic with no credibility.
then he's vindicated because all the other reports that come out use more tangible sources and it's exactly what he's been saying all along.
