Not sure is scrypt ASICs can make that much difference, the hashing requirement is limited by memory. I think the cost of these ASICs + the memory chips would be somewhat equal to most GPU's in the market.
Yes that will be the case, scrypt asics even IF they arrive, won't be as big a game changer as the BTC asics were. Thats just the way scrypt works.
Plus given the choice of going with GPUs vs ASICs : I would prefer GPUs since they can be used for other tasks as well. As far as ASICs are concerned they will just do one funtion only,i.e, the function for which they are built. So resale value/price guarantee is much more with a GPU vs an scrypt ASIC.
Main advantages are:
1. Lots of power saving. Best suites for the countries where the cost per watt is high.
2. Initial ASIC scrypt mining hardware is just a stepping stone. Based on these, future ASICs will be re-designed in cost effective manner. More china manufactures will enter the market that will reduce the cost significantly.
3. Ease of use.
4. Occupies less space.
Well the power difference will not be that much as compared to a GPU of the same hash rate. the ASIC may consuming a bit less if using 28nm chips. but the main problem is the memory requirement for scrypt to function properly. the ASIC needs to be integrated with a memory chip most probably a inbuilt RAM . The ram problem is solved by GPU's, as it comes with inbuilt ram.
The only way scrypt ASIC would be cost effective is by introducing something like a 16nm (currently developed by IBM) or an experimental 8nm carbon nano-tube based ASIC. This will significantly reduce power consumption and increase hashing power. Till then ASIC's and GPU might be going on head to head. But development will happen and ASICS will become far more efficient and faster. on the long run ASICs for scrypt is the way to go.
Will connect you to a Hyd chappie who has access and knowledge of FPGA. He was talking to me about a scrypt FPGA.
Sounds like an interesting project.
Yep I'd like to know more too if possible.
