When used on a single processor, the search is said to be slowed down about 5% compared to Junior 8.0, which we also have tested. After 545 games Junior 8.0 Athlon 1200 MHz now has a rating of 2784, 85 points more than Junior 7.0! The present rating difference between the single and multiprocessor versions of Junior 8.0 is 36 points. The slight speed difference between them should give only 3-4 rating points. If the programs otherwise play identically, and that is what I have understood, the rest must be attributed to statistical factors."
