Igor: I guess this one would be more interesting:

If I understand the specs on their site right, they achieve 5,6 billion DES keys per second with only one or two cards. Now imagine what will happen if you got enough money and put in 15 more cards...
My (terribly uninformed and based of calculations that might as well be wrong) guess is: not much more if you'd spend the same money on graphics cards (and don't care about the energy costs and cooling requirements).
As posted above, achieving the same WPA-PSK-"bruteforcing" speed as a single E16 with graphics cards requires almost the same amount of money - not taking into account the possible improvements in WPA/PSK-bruteforcing speed sc00bz posted ITT.
So I'd say that FPGAs aren't really "faster" than graphic cards when comparing the purchase price. It's space and energy requirements where they really shine - the E16 here draws just 3.45 watts. No need for a 800 watt PSU there :sigh:
Well, and as others said, FPGAs require someone to code shit for them - and there are only a few people doing this, and they're all David Hulton
I looked around, and the only current/free FPGA-accelerated software seems to be jc-aircrack
. The stuff from OpenCiphers
is rather dated and it wouldn't be fair to compare it to other crackers.
Also, since AirCapture uses PICO cards, I guess their system with multiple FPGAs is actually a PICO supercluster. PICO sells two versions, one filled with E12s and one filled with E16s. The E16 versions consists of a maximum of 77 FPGAs in a cluster - 210 would be three clusters then, using 12 U of rackspace.
Any owner of a PICO/Aircapture FPGA supercluster up for porting the future distributed BarsWF to Verilog/VHDL and connecting it to the internet? C'mon, there must be at least some spooks around here.
