What is the size for the caches (L1 and L2), what ghz range is it? 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. > >Not trying to sound condescending, I really dont understand it. > >Sincerely, >Joshua Shriver > >On June 15, 2004 at 04:17:09, Gian-Carlo Pascutto wrote: > >>On June 14, 2004 at 21:07:03, David Mitchell wrote: >> >>>2) Xeon >> >>>4) Centrino >> >>Centrino should easily outperform Xeon clock for clock. >> >>For some programs it will even outperform an Opteron clock for clock >>in 32 bit mode. >> >>-- >>GCP
