Intel's Pentium 4 3.06GHz: Hyper-Threading on Desktops

High End Workstation Performance - ScienceMark 2.0 Beta

With this review we're also introducing ScienceMark 2.0 into our test suite; the benchmark focuses on FP-intensive scientific calculations. For more information on what's going on in the tests themselves visit www.sciencemark.org.

High-End Scientific Performance ScienceMark 2.0 Beta - Molecular Dynamics AMD Athlon XP 2800+ (2.25GHz) Intel Pentium 4-HT 3.06GHz AMD Athlon XP 2600+ (2.13GHz) AMD Athlon XP 2200+ (1.80GHz) AMD Athlon XP 2000+ (1.67GHz) Intel Pentium 4 2.80GHz AMD Athlon XP 1800+ (1.53GHz) Intel Pentium 4 2.53GHz Intel Pentium 4 2.26GHz Intel Pentium 4 2.0AGHz (400MHz FSB) Intel Pentium 4 1.8AGHz (400MHz FSB) 80.8 81.0 88.8 100.2 107.7 109.4 121.8 125.9 143.4 169.6 197.2 | 0 | 39 | 79 | 118 | 158 | 197 | 237

The Athlon XP does quite well in this test thanks to its very strong FPU however the presence of Hyper-Threading helps keep the 3.06GHz Pentium 4 within 0.2 seconds of the Athlon XP 2800+.

High-End Scientific Performance ScienceMark 2.0 Beta - Primordia AMD Athlon XP 2800+ (2.25GHz) AMD Athlon XP 2600+ (2.13GHz) Intel Pentium 4-HT 3.06GHz AMD Athlon XP 2200+ (1.80GHz) Intel Pentium 4 2.80GHz AMD Athlon XP 2000+ (1.67GHz) Intel Pentium 4 2.53GHz AMD Athlon XP 1800+ (1.53GHz) Intel Pentium 4 2.26GHz Intel Pentium 4 2.0AGHz (400MHz FSB) Intel Pentium 4 1.8AGHz (400MHz FSB) 466.3 507.4 531.2 576.8 589.9 613.5 643.1 653.7 711.9 841.2 899.9 | 0 | 180 | 360 | 540 | 720 | 900 | 1080

Hyper-Threading does not help nearly as much in the Primordia test where the Athlon XPs manage to pull away from Intel's flagship.
