Why is this? that AMD is not advertising AMD Sempron as 64 bit processor, Even they are more superior to old (Socket 754) Athlon 64 As have SSE 3 also...

This puts me ask ?

Are they Really Sempron 64 bit....

QUOTEAre they Really Sempron 64 bit....
Not all 754-pin Sempron processors are 64-bit enabled (Socket A Semprons don't have 64-bit capability at all as they're Athlon XP based).

Those 754-pin parts that do support AMD64 (64-bit capability) are pretty much equivalent to a 754-pin Athlon 64, but with a smaller L2-cache and lower clockspeed (and without Cool'n'Quiet support on 'smaller' models, usually <3000+).
Unlike the old 754-pin Athlon 64, they also use newer 90nm SOI cores - the mainstream Athlon 64s have moved to the newer Socket 939 platform.
