the cost of the gates is irrelevant [except for leakage current],
it doesn't come into the equation of satisfying both end-user
requirements.

that post clearly indicates that there are different user requirements,
where different hardware fails to meet both.

i will state it again: we may solve this by providing the *end users*
the option to choose the level of accuracy that they require.

what the Khronos Group demands can take a back seat.
