Now that there is new data on die size, I updated the GH/wafer table:

Code:

wafer(mm) chip process(nm) die(mm^2) GH/s(per die) DpW GH/s(per wafer)
300 KnC 28 441,00 25 128 3200,00
300 bitfury 55 14,44 2 4717 9434,00
300 bfl 65 56,25 4 1167 4668,00
300 asciminer(?) 130 17,50 0,333 3877 1291,04
300 avalon 110 16,13 0,282 4214 1188,35
300 asciminer(?) 130 21,7 0,333 3112 1036,30
(DpW, die per wafer; yield percentage not taken into account)

Die size is less than 336mm2.
I think 18x18mm

Another detail for a better table. As far as I know, 130nm(110nm) are still manufactured based on 200mm wafers. 65nm(55nm) nodes were the first built with 300mm.

Ummmm. KnC is doing a 28nm process and getting only a third of the GH/s per wafer that bitfury is getting at 55nm?

its ok, all the knc supporters tell me that its not an issue. Since they dont care about power i guess, which leads me to the conclusion that they have unlimited power capacity at their mining location. Oh ya they will also say that the power usage predictions are the worst case scenario so it can be better than bitfury when released.

um.... Yeah? If you had read some more in here you would know that they like to understate specs instead of giving specs that look good but can't be made into reality...

BFL had more per wafer also, and they have been getting chips made for a while now... So it most certainly has been "made into reality", for less, at an inferior process node.

Pray tell, where exactly did I mention BFL? funny thing that you mention them... I only told you what KNC stated, which is only that they don't like to give specs they can't deilver,
Please stay focused on topic, you sound like a kid with OH A CUTE LITTLE DOGGIE... if you catch my drift.
