Just got an Intel i7 920 processor and am running Ubuntu 8.10 server on it. It's supposed to be a quad core CPU but when I looked in /proc/cpuinfo it showed eight:
$ grep -e ^processor -e "^model name" /proc/cpuinfo processor : 0 model name : Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz processor : 1 model name : Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz processor : 2 model name : Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz processor : 3 model name : Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz processor : 4 model name : Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz processor : 5 model name : Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz processor : 6 model name : Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz processor : 7 model name : Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz According to the wikipedia article[1], that's to be expected: "Re-implemented Hyper-threading. Each of the four cores can process up to two threads simultaneously, so the processor appears to the OS as eight CPUs." That is a very pleasant surprise. http://en.wikipedia.org/wiki/Intel_Core_i7 Regards, - Robert --~--~---------~--~----~------------~-------~--~----~ Central West End Linux Users Group (via Google Groups) Main page: http://www.cwelug.org To post: [email protected] To subscribe: [email protected] To unsubscribe: [email protected] More options: http://groups.google.com/group/cwelug -~----------~----~----~----~------~----~------~--~---
