If Intel *really* wants a higher TDP, they'll have to recompile the VHDL for the chip with the TDP paths specified as 16-bit rather than 8-bit.

The 4095.75 is basically a hack where the chip re-interprets the 8-bit unsigned integer path as a weird 8-bit floating point value. This is only to support over-clockers.
