But how do you know it doesn't have double vias? Im certain that the RV740 didn't have them and yet lessons learnt were applied to Evergreen which featured them. From what I am aware, (correct me if im wrong) as I have been following this topic as well is that Charlies sources were off on their measurements because I saw a cut down GT 460 die measured to roughly 330mm^2 using accurate instruments. The rough part comes from the fact that the die package was damaged slightly when they cut the heat spreader. However this is relatively inconsequential. I do have to agree that Southern Islands could be quite powerful. Especially as they can take advantage of faster and larger 2Gbit GDDR5 32bit wide ram chips. This would solve their bandwidth and especially frame buffer issues whilst at the same time allow them to take advantage of better shader utilization and front end architecture. I also have to agree that they are only really producing Fermi chips for the professional market. Its pretty much the same deal as the EOL of their last range of high end cards as well. |
We're going to have to disagree about Charlie. Personally I believe him, but what ultimately matter is i) are Nvidia's products good value for money? and ii) Are they making enough profit on them to be viable as a company?
In the case of i), even Charlie admits the GTX 460 is a good product.
In the case of ii), I currently believe Charlie that Nvidia will not survive long in the post Llano/SB era as their core business is poorly managed and their other businesses (chipset, Ion, Tegra, Tesla) are not expanding.

Is this your source: http://image163.poco.cn/mypoco/myphoto/20100731/19/5519975820100731193928021.png
If so, that wasn't measured directly but instead the person who took the photo and person who measured the die only from the photo were different people. Not as accurate as getting a laser out on a real die.
