NetBurst (Prescott, Nocona)

Intel NetBurst (Prescott, Nocona) (2004) supports x86-64-v1.

x86-64 level
x86-64-v1
Vendor
Intel
First products
2004
Products
Pentium 4, Pentium D and Pentium Extreme Edition models with Intel 64; Xeon (Nocona, Irwindale), Xeon MP, 5000, 7000 and 7100
Segments

GCC target
-march=nocona

Only the later NetBurst models implement Intel 64. GCC's -march=nocona leaves out LAHF/SAHF in 64-bit mode, which -march=core2 adds.

Why not x86-64-v2?

NetBurst (Prescott, Nocona) lacks LAHF-SAHF, POPCNT, SSE4.1, SSE4.2 and SSSE3, all of which x86-64-v2 requires.

Feature checklist

Features required by each x86-64 level and whether NetBurst (Prescott, Nocona) has them. OSFXSR and OSXSAVE are set by the operating system; the table checks the hardware features they depend on.
