Why work on a B-revision if you can work on a full-fledged refresh?
Refresh on the same node? I guess that could work, since they can start cutting some of the "fat". Maybe they've aimed too much this time around.

A refresh sooner than this fall wouldn't make much of any sense. Though the rest of the family is likely to come by then.According to what I've heard it may be sooner than that.

What was R580?
Yeah. It would be nice to see GF102 at the same time GF104 is rumored to come out (in 3 months)!
A word of warning. NV's newest campaign involves getting everyone shouting GF104! GF104! and how good it will be compared to GF100.. I can only say.. don't hold your hopes up. Specs put it past GT200, performance and (power!)characteristics don't.
(i'll even make a GF104 swear jar myself, since it's going to be ridiculous the coming months.)
The cost rises non-linearly with die size.Maybe someone can explain this to me from Charlie's article:
"This means Nvidia can't take the time to respin it. ATI will have another generation out before Nvidia can make the required full silicon (B1) respin, so there is no point in trying a respin. The die size can't be reduced much, if at all, without losing performance, so it will cost at least 2.5 times what ATI's parts cost for equivalent performance. Nvidia has to launch with what it has."
It, i.e. GF100, is faster (even Charlie admit's that) by some varying percentage, and, at max. 80 percent larger (600 vs 334 sqmm), yet it's supposed to cost 2.5 times as much? I fail to graps the math here…
A 10-15% win with a 58% larger die, is an architectural smack-down in my book. To be fair, fermi is the beginning of a new architecture (with a lot of headroom) while ati needs substantial improvements in the near future to remain competitive. Considering fermi's gestation, it is not at all obvious that amd can pull them off without missing their initial clocks/yields/power/area targets either. Overall, Fermi is a nice architecture. GF100 is it's meh implementation. The heat/noise and missed clocks only serve to add insult to injury.But then, it must be really hard for Charlie to admit that even an unmanufacturable salvage part with way missed clock targets and disable units is beating the HD 5870 perf wise. So he calls it slow. I wonder what that does to the performance of an HD 5870 in his view? More than slow? Me, I'm quite happy with the perf of my 5870 and didn't even see a need yet to try and overclock it.
No idea about voltages.I also wonder, what he was expecting the voltages to be in Nvidias planning. According to HT4U.net, they're quite low especially under load:http://ht4u.net/reviews/2010/nvidia_geforce_gtx_480/index10.php
NVIDIA GeForce GTX 480 GPU 50 / 100 MHz 1,004 Volt 700 / 1401 MHz 1,011 Volt
RAM (GDDR5) 67,5 MHz 1,584 Volt 924 MHz 1,583 Volt
Care to elaborate? Specifically for yields instead of binning.Die size isn't the only factor of chip pricing.
Well, then it should be a couple of times more expensive, compared to Cypress I guess.
Yeah, there's no way those are the correct numbers.Charlie said ~10K 480s and ~20k 470's. Let's make it 50K total chips from 9K wafers @$5K/wafer.
That makes it $900/working chip.
Let's see what Fuad will do this time around after the shaft he received at the hands of nvpr @gf100.(i'll even make a GF104 swear jar myself, since it's going to be ridiculous the coming months.)
Er, isn't the GF104 supposed to be a cut-down version of the GF100? It might be "good" in efficiency terms compared to the GF100, but I sincerely doubt it will be higher-performance.A word of warning. NV's newest campaign involves getting everyone shouting GF104! GF104! and how good it will be compared to GF100.. I can only say.. don't hold your hopes up. Specs put it past GT200, performance and (power!)characteristics don't.

Which campaign? GTX480 is the most power hungry graphics card ever made (exceeds TDP even in current games), it's also the most noisy graphics card ever made, it's overpriced, still unavailable, and its performance is 15% better than single chip competitor, despite it was planned to compete with dual-GPU part. What exactly is better on this product, than the most pesimistic predictions stated?
it's also the most noisy graphics card ever made,
