Hi Tom, if you click on the link it shows the following: Up to 8 physical cores or 16 logical cores through Hyper-threading
The old Hyperthreading implementation was not really two logical cores per physical core (some things were shared such as the floating point unit), but Intel changed the implementation when AMD came up with the 6-12 physical cores, such that now Intel Hyperthreading logical core is performing much better and AMD comes not even close in termes of performance. So if you calculate with an Hyperthreading enabled 6 core, you get 4,5 instructions per clock cycle per core.

That translates to each core completing about 9 instructions per clock cycle. I am skeptical. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN
