Does my processor support SSE2 and EM64T, required by the 2010-family CAD application?

The CPU instruction set extension - SSE2 (Streaming SIMD Extensions 2) can accelerate some computations used in CAD software applications. This extension is supported in all current processor types (sice Pentium-4) by Intel and AMD. The SSE2 support is required for AutoCAD since version 2010, for Inventor 2009, Revit 2009 and 3ds Max since 2009.

Processors with SSE2 support:
Intel Pentium 4, Xeon, Celeron, Celeron D (NetBurst), Intel Pentium M and Celeron M, Intel Core CPU (Core Duo, Core Solo), Intel Core 2 CPU (Core 2 Duo, Core 2 Quad), Intel Core i7, Intel Atom, AMD Athlon 64, Sempron 64, Turion 64 (K8), AMD Phenom, AMD Opteron, Transmeta Efficeon, VIA C7, VIA Nano and newer.
Processors without SSE2:
AMD CPU with Socket-A (before Athlon 64), Intel Pentium-III, Pentium-II, their Celeron versions and other CPUs older than Pentium-4, Via C3, Transmeta Crusoe.

If you want to use the 64-bit version of the given CAD software, your processor must also support the EM64T technology (Extended Memory 64 Technology), labeled also as "Intel 64" or "AMD64". This technology is also standard in all modern microprocessors by Intel and AMD.

Examples of processors supporting the 64-bit technologies:
Intel Xeon, Intel Pentium 4, Intel Pentium D, Intel Pentium Extreme Edition, Intel Pentium Dual Core, Intel Celeron and Celeron D, Intel Core 2, Intel Atom 200 and 300, Intel Core i7, Athlon 64, AMD Opteron and newer.
