There are many variations of the Athlon XP 2600+. One infact runs 1916.6MHz
(11.5x166) and has 512k L2. This is the model 10 XP. The model 8 XP with 256K L2
runs in two flavors. The 2083MHz 166fsb version and the 2133.3MHz 133MHz fsb
version. The mobile Athlon XP 2600+ has 512K of L2 and runs 2GHz with a 133MHz
fsb.

Since L2 doesn't make a difference on these chips in chess.. you're looking at a
maximum performance difference of 11.3% between the 2600+ chips.
