It is not bitcoin.. for FPGA it should be in the KH/s, even multiple graphics cards only give you low MH/s
Wrong. FPHA has nothing to do with it. It's because LTC is SCRYPT, and I am assuming the goal of the FPGA's would be to reach into MH/Sek otherwise why design them?
FPGA's are likely to continue to lag behind GPU for litecoin, currently there are no products I know of that can produce in the MH/s range for a single unit.
I.E a single GPU/ FPGA (even with multiple cores), and the reason to design with FPGA are numerous, I will give you two.
1. lower power consumption
2. Ebay scrap. (this works fine for individual miners, but not if you want to build and sell to the public.....)
So even if I cannot match GPU:FPGA on a 1:1 basis, I can out purchase on a 1:n basis
