Title: Which chips support the hash functions for bitcoin mining
Post by: papajo on October 10, 2013, 06:45:57 PM
This question is technical I would like to know which family of chips are capable of doing this job (and as an extend are used in the GH/s machines out there )

Are other electronic chips capable of doing this job?


My ultimate thought on this is the idea of maybe purchasing a big batch of chips directly from a manufactuer and hire an engineer to combine them together in a pcb for just doing bitcoin mining..


It could make sense if the chips used for this are not expensive (the high price on the miners could be more like because of the high demand big rush ) the actuall cost to make them from scratch maybe not so bad.. more simply to put to buy a retail miner machine that does 2th/s you need atleast 5000usd.. why not pay 3000-4000 usd to a professional to make some basic microcode and design to combine lots of chips for integer calculations supporting SHA256 (which would cost lets say an other 3000 for 100 of them maybe that would produce little lower same or better GH/s perfomance at the same cost but could be almost imediatly available to you every time you want to upgrade (just ordering the chips the pcb etc the design is already done in the first place and you got another TH/s machine without waiting half a year for it to be delivered)

so anyone that could tell me some technical details on this?

thnx

You can order bit fury Avalon etc chips.
You will need to dedign your own ASIC otherwise (or have someone else do it)

Or you can get chips like the kintex or virtex 7 and have someone design PCB and code for those (not as efficient)

I would like to get more into it just for the science of it I mean what is the target when designing an asic for hashing bicoins? I know a few things about GPU and CPU x86 architecture but very little to nothing about those chips

You want something that is good at sha-256 hashing and Integer calculation (not Floating points, that is difference between NVidia and AMD, NVidia is better at Floating Points, AMD is better at Integers)
