<I do not know enough about the trace cache yet. Why does it transfer every other clock? Does it simply take two local cycles to move all the data to the next stage, or does the TC happen to have, as others might suggest, an 0.5x local clock multiplier and the "every other clock" thing is a reference to the MCLK?>

Its the latter. Look here on page 1-9

developer.intel.com

The decoder and the TC are in a box called front-end. They are both running at half of the MCLK. The front-end is probably as large as 30% of the chip, running at half the nominally quoted frequency. This is why Intel is hiding this information. It would be devastating to P4's marketing scams.
