<Which tags?> I could be wrong about increased
superpipelineability. It looks like every tag was
redesigned with newer XOR gates:

"To achieve Pentium-III processor operating frequency,
numerous speed paths needed to be optimized. One
category relates to the use of domino tag comparators
incorporated in various caches and buffers across the
micro-architecture comprised of 8T XOR cells. An XOR
gate shown in Figure 5.7.3 outperforms previous
implementations on this processor in terms of delay,
contention, backwriting, and reduced
cross-capacitance impact." - from ISSCC '99
