I think we should use SSE3 as default. It is already ten years old. Most users (99.999 %) who want binary wheels have an SSE3 capable CPU. According to Wikipedia: AMD: Athlon 64 (since Venice Stepping E3 and San Diego Stepping E4) Athlon 64 X2 Athlon 64 FX (since San Diego Stepping E4) Opteron (since Stepping E4) Sempron (since Palermo. Stepping E3) Phenom Phenom II Athlon II Turion 64 Turion 64 X2 Turion X2 Turion X2 Ultra Turion II X2 Mobile Turion II X2 Ultra APU FX Series Intel: Celeron D Celeron (starting with Core microarchitecture) Pentium 4 (since Prescott) Pentium D Pentium Extreme Edition (but NOT Pentium 4 Extreme Edition) Pentium Dual-Core Pentium (starting with Core microarchitecture) Core Xeon (since Nocona) Atom If you have Pentium II, you can build your own NumPy...
