And in fact, AMD processor support not only ssse3, but even sse4.1.

I am not a CPU expert but I think it is SSE3 made the difference in my case: image worked in Athlon64X2 while it didn't in Pentium-M. According to http://en.wikipedia.org/wiki/SSSE3, SSSE3 doesn't make to AMD chips. > How does the performance balance out across the architectures if this is a > generic OS ? I don't know how to do test but found http://www.anandtech.com/show/1618, obviously it didn't test Inter CPU esp. Atom. Does it make much difference? >If ATOM benefits so heavily from SSSE3 instructions, how does ARM keep up. ARM is RISC so that it doesn't provide more and more instructions for some purposes like CISC chip. According to my experience, armv5 is good enough for most ARM chip with very good backward compatibility and VFP boosts the performance for floating point operation like 3D. Thanks. JD Zheng
