They are _not_ the same chip. I am talking _xeon_. And all current clock speeds of xeon support SMT. You are talking PIV. Only the 3.06 ghz and beyond will support SMT. DO you get the difference now? PIV != xeon. xeon != PIV. In fact, from my recent testing, using intel's compiler to target a PIV produces an executable that works fine on a PIV but not on my 2.8 xeon. > NoNoNo > > System Bus > System Bus > > 533MHz > Up to 533MHzUp to 133MHzUp to 100 MHz > > > Cache > Cache > > 512 KB full Speed L2 Advanced Transfer Cache >" > >the >http://www.intel.com/eBusiness/products/server/processor/index.htm?iid=ebus+servers_info& > >link is a very recent one. > >before that the handbook just said Xeon MP processors had SMT. Look at their web site.
