I am probably planning to buy an FPGA. Which one is faster?

The Xilinx Spartan 6 XC6SLX25 FPGA, Speed Grade 3 or an Spartan 3E 500,000 gate FPGA?
Both aren't really suited well.
I estimate the XC6SLX25 at about 20MH/s, and the Spartan 3E 500K at <2MH/s.
You'll want to get an XC6SLX150-2, those can do about 190MH/s (at least ArtForz claims to have achieved that).

The next best Spartan3 has 1200K gates vs this 500K, so it might be able to quadruple the units.
Still <5MH/s.

But congratulations for making it work Smiley
