In the case of the Centrino (Banias architecture) the L2 cache is not a factor
because use of the L2 consumes power and the the main point of the Centrino was
to reduce this for mobile computing. The combination of a very advanced branch
predictor, micro-ops fusion and a dedicated stack manager make the Centrino a
much more efficient CPU and thus faster. The biggest boost a chess engine sees
on one of these CPUs is due to the advanced branch predictor.
