I was browsing the Baikal X10 thread and what the OP said there, this was March 12:

I am building my own FPGA rig and after a detailed analysis of all current algorithms, I can say that all algorithms will soon be mined by ASIC/FPGA except equihash and ethash.  Equihash will fall to ASIC's in about 6 years when we can get 144MB of SRAM on a single chip.  Ethash will not fall to ASICs ever, in my opinion.  The 2GB scratchpad is just too big.

Cryptonight and Cryptonight-Lite are mildly ASIC resistant.  This means that even a dedicated unit like the Giant-N cannot 'crush' GPU's.  It can beat them marginally in terms of ROI.  But for other coins, ASICs crush the GPU's by hundreds of times.

Eric

Two things to to note: Equihash falls to ASIC in 6yrs and Cryptonight ASICs will beat GPUs only margnially.


So a couple of days later, Bitmain announced X3 with 10x Cryptonight performance than Giant-N, and equivalent to 100 odd Vega-64s.

And 2 months later, we have the Z9 Equihash ASIC.


And now I have my doubts on OPs assessments...


Edit:

This is proposed performance for Phi on VC1525:

Phi1612 (Luxcoin, Folm): 5.2GH/s (650MH/s per card x eight) ($456/day at Apr-30 prices)

So 650MH/s = 20x 1080Ti

That should be well within an ASIC range, if and when one emerges.


Edit2:

While the OP maybe an FPGA expert, he does not appear to have much experience in what ASICs can do. Bitmain has!
