"As perhaps can be understood from it's name, Deep Junior 8.0
is primarily intended for PCs with several processors. 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."
