I'm not sure if you can boil everything into 'just 200 MHz more' TBH. (Oh where are the days when 200MHz was all we ever had... gone, with t3h wind(ows).) Newer processors tend to, besides higher clock and cores/dies, possess more cache (L1, L2, L3) so, more, and faster, memory, closer to the processor. Also improvements in the processing pipeline/branch prediction, RAM bus throughput (memory clocking x width) etc. All that matters and improves (if you can find this data for your old machine, compare it with the new one) regularly. If there is a 'single threaded, memory intensive' benchmark you can compare on both machines, there is a good chance, that compilation MAY improve that much. It's not scientific, as benchmarks can not compare (or rarely can compare) to the real load, only for comparing benchmark-to-benchmark. Hope this helps -L. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
