What about power consumption?

[pclmulqdq]

The FPGA will have higher static power (running all the overheads) but probably lower dynamic power for the same design. 40 nm is old at this point for high-performance chips.

The static power might also depend on whether the FPGA is an SRAM type or a floating-gate type, I'd think. Does Lattice have any parts fabbed in relatively new processes?

[pclmulqdq]

You're right. Pretty much everything is SRAM now, though. Even the MAX 10 is an SRAM FPGA with a flash-backed storage memory.
