What is the current FPGA:GPU ratio among miners?

Please vote your informed opinion!  I would love to know how efficiency of mining hardware has evolved over time, but historical values are hard to estimate because most of the history has been a transition period of some sort. This poll might at least provide the current estimate. Thanks!

I think you can look at some of the forum posts that have order and delivery history to help get some data. Interesting question.
I'm curious why you are curious

GPUs will be getting turned off in large droves, however FPGAs can be expected to remain on until ASICs hit, due to their negligible run cost. If you know the FPGA/GPU ratio, you can make a reasonable stab at what the hashrate will be after halving.

I have convinced myself that network hashrate is essentially irrelevant for my understanding of mining economy. What I want to know is the history of total mining investment: hashing power expressed in USD (equipment cost), and hashing efficiency in electricity USD/day.
Many things could be inferred from such estimates, for example how expected ROI has evolved over time.
I'm afraid you are right: the only way to get some estimates would be to skim through old advertisements. That's lots of work for someone who is simply curious.

Also the fact that FPGA's aren't easy to sell while GPU's, espescially newer well working units still have most of their original value... and christmas buying season is approaching.

You may have seen the other thread are you shutting down. yes/no/ i have fpgas
last I checked it was around 11% saying they have FPGAs.

Fpgas here to:)

Once ASIC hitting ill decide what to do with them.
The worse part are the climbing energy costs here in Germany.
I'll now pay about 30ct € (that's about 40ct $ US)... It's going to climb to shocking 45ct € to 50 ct €... (about 49ct $ to 55ct $ US) as the first forecasts tell.

Mining will be getting less profitable around here. Even with ASIC...
