Are there any Tukwila benchmarks that show it leads over Sparc ?

The out of order execution will likely be restricted to the instruction
blocks that the compiler has determined can be pipelined. This may be
more marketing hype than a true change in architecture.

Consider that a true change in architecture to really make it out of
order, would likely require changes to all compilers and recompiling of
software with new compilers, and it would also require that the new
chips support the old executables with the EPIC mentality. Me thinks
this would be way too big of a change to be acceptable.


Intel likely needs to hype up IA64 now that it has been declared dead by
Oracle and it will try to find any way to hype it.
