Comparing LUTs isn't a particular effective way to compare fpgas, especially between vendors. Altera uses a different Logic cell so the number may be actually higher.

While they aren't exactly comparable it will give you a ballpark figure.  If you get 20MH/s w/ chip from one vendor with X LUTs a chip from another vendor that also has X LUTs isn't going to get 500MH/s.

Although I would try to find one of the bigger chips of them.

This one is listed on hardware mining comparison
https://en.bitcoin.it/wiki/Mining_hardware_comparison.
Board is Terrasic DE0-Nano. Its rated at 6.25MH/s but thats are old cores. With some further improvments it may reach 10MH/s.

I take that back.

According to the Cyclone IV overview [http://www.altera.com/literature/hb/cyclone-iv/cyiv-51001.pdf],  The CE115 has 114,480 LE's (logic elements) and gets ~100MH/s, the CE22 has 22,320 LEs

Probably more like 25-30MH/s.

Sub 20MH.  w/ only 22K LUTS to work with the bitstream is not going to be unrolled much which means more loop overhead.

Without researching the chip on this board, just going by the Altera EP4CE115C7 listed on the mining hardware comparison page (this one is a EP4CE22F17C6), maybe ~60-80MH/s?

Probably not worth the 139EUR they want for mining purposes when there's better FPGA options around the forums.
