Hi Jirka,
>Any comments on this?
I am not familiar with the Athlon64.
It is possible that some marketroids misunderstood "simultaneously processes four 32-bit floating points" as "128-bit floating point arithmetic".
>Which processors supports 128-bit floating point arithmetic?
None that I work with. These days, I just know about Pentium 4, PowerPC G4, SPARC64, DEC/Compaq TRU64's Alpha.
If you REALLY need the higher precision of 128-bit floating point (or better), there are C++ libraries to support floating point (and fixed point) numbers with greater precision.
HTH,
