sorry - (28/65)^2 is 0.18. so, roughly 1/5th the power consumption
of roughly 8 watts worth of performance with rubbish leaking current.
i'd say you'd be on target for somewhere between 0.5 to 1 watt power
consumption for the FPGA, but the only people who can really confirm
that are Xilinx.
and the performance of the FPGA is rouuughly equivalent
(finger-in-air) to the Spartan 3 4000, so roooughly finger-in-air,
whatever specs were projected for the OGP, it'll be about the same
(half or double). it's not far off. it's certainly not going to be
close to order-of-magnitude either way [performance-wise].
