GF100 DIE. 50% or maybe less, i dunno how much the 2x float takes of space. but i reccon its roughly around 270-330 nm. Ati has 334 NM for 5870. GTX285 has ~484 Estimate suggests its a fairly high production cost for the performance. The question will remain, is the GPGPU stuff that nvidia taunts the big deal, or wont it be much use for us. Surely, they HAVE to do something, cause they are getting well, smashed between AMD and Intel, both making ONdie NB, SB, GPU. Making Nvidia chipset with IGP obsolute! Nvidia chipsets all in all. Thats huuuge incomes, immagine, Only high end laptops would have nvidia, thats just about 20% ? ouch... Nvidia's GPGPU (Tesla) really is a great income source! Will it affect us costumers, design cost for two seperate designs really isnt worth it either.(archs) Really no hard fact on the die size, estimates, but well, atleast 260mm^2. unless nvidia has a magic way to shrink the size of a cuda core.
