I ran the Deepfritzmark and Shreddermark tests with hyperthreading disabled then enabled with some very confusing results that I am hoping someone can help explain: Test set #1 Hyperthreading Disabled, 64MB Hash, Engine Parameters @ default Shredder 7.04: Shreddermark: 2227 +- 0 (1.5s) 705kN/s Deep Fritz 7 : Deepfritzmark: 2724 +- 44 (3.1s) 2252kN/s Test set #2 Hyperthreading Enabled, 64MB Hash, Engine Parameters @ Default Shredder 7.04: Shreddermark: 2227 +- 0 (1.5s) 803kN/s Deep Fritz 7 : Deepfritzmark: 2476 +- 0 (3.2s) 2555kN/s Test set #3: Hyperthreading Enabled, 32 MB Hash, Engine Parameters @ Default Shredder 7.04: Shreddermark: 2784 +- 0 (0.4s) 907kN/s Deep Fritz 7: Deepfritzmark: 2476 +- 0 (3.4s) 2532kN/s Test set #4; Hyperthreading enabled, 16MB Hash, engine parameters @ default Shredder 7.04; Shreddermark: 2784 +- 0 (0.4s) 1008kN/s Deep fritz 7: Deepfritzmark: 2476 +- 0 (4.5s) 2544 kN/s This is somewhat confusing as Fritz scored the highest fritzmark with hyperthreading_disabled_ even though his kN/s were_far_lower. Shredder scored far better with it_enabled_ both in result, speed, and time to solution. Also Shredder seemed to benefit more from the smaller hash sizes where Fritz seemed relatively worsened by them. Does anyone have any insight as to these seemingly contradictory results? And would I be better to run Deep Fritz with the hyperthreading diasabled even though his kN/s is considerably lower? Charles
