Infinite Loop / The Apple Ecosystem  Benchmark: Leopard needs
64-bit Intel to beat Tiger  Leopard wins this cat fight in
64-bit mode on an Intel Mac, but in 32-bit mode …  The folks up
north at Primate Labs have some benchmarks of a PowerMac G5 and
a Core 2 Duo iMac running under Tiger and Leopard. They used
their cross-platform benchmark Geekbench for the tests.  The
iMac did pretty well. Under Tiger, it got an overall score of
2699, with 1000 on the scale representing a 1.6GHz G5. Under
Leopard, the iMac's score went down a bit to 2618, but in 64-bit
mode, it was 2878. Although the results varied from one test to
another, the trend was pretty clear: the iMac performed the
tests included in Geekbench a bit slower under Leopard 32-bit,
but faster under Leopard in 64-bit. The only exception was
memory performance, where Leopard was 5 percent slower,
regardless of the number of bits.  When it was the G5's turn,
things didn't look quite as rosy. This machine had a score of
1013 under Tiger, but performed a good
