Your's is an interesting data point.  It makes you wonder whether or not RDRAM
is a terrible choice for a chess computer.

The main question it raises, however, is:  "How much difference is there between
Fritz 8 and Crafty v18.11?"  The Crafty v18.11 Benchmark may not be
representative at all when predicting Fritz 8 Kn/s.  We need Fritz 8 data versus
computer configurations.
