So my concerns about the skyscraper effect are unwarranted as H personally asked AMD about my questioning of HSF removal and the worry about damaging gfx cards. Still they may only be answering the question i posed about 1st Gen HBM because it can only achieve 4 stacks but Gen 2 will be 8, 16, 32 stacks(?) and then they might have an issue with the skyscraper effect. I'm not sure if it means 4x4 Gen 1 =4 gb but future Gens maybe 8x8 or 4x8 or 8x4?

Ide imagine the new gpu's are going to look like the old ps3's gpu when delided. http://community.us.playstation.com/t5/PlayStation-3/My-CPU-GPU-look-different-to-repair-guide/td-p/6883680

Thanks Hilbert, I think understand how HBM works now. I know I didn't before reading this article. 🙂

We need unified RAM tech...(similar to consoles), imagine 16+ of these..
