The ply next to the name of the engine is where I took the total node count and divided it by the time to ply. Here are the results: Athlon XP 2.5GHz and 384mb hash for all engines: Shredder 8 @ 18 ply: 218fsb: 409kn/s 166fsb: 409kn/s X3D Fritz @ 15 ply: 218fsb: 1116.9kn/s 166fsb: 1116.9kn/s Hiarcs 9 @ 13 ply: 218fsb: 275.35kn/s 166fsb: 269.23kn/s Junior 8 @ 17 ply: 218fsb: 1999.54kn/s 166fsb: 1987.98kn/s Deep Fritz 7 @ 15 ply: 218fsb: 1144.69kn/s 166fsb: 1129.83kn/s As you can see a higher fsb (and lower latency) did next to nothing. ShredderMark definitely has some problems.
