~1000 Luts. 1 Lut = 6-24 gates on average. a bit pmore but still pretty close.

A LUT can be 10 gates and it can be 100+ gates. You just can't compare FPGA LUTs to gates like that.

FPGAs have things like block RAMs and multipliers. Those require a ton of gates, but don't increase required FPGA LUT count by much.
