can someone find the benchmark numbers for these 2 intel cpu's, the passmark or whatever is used. intel xeon x7542, 2.66ghz, 18MB cache (cpu family = 6, model = 46) intel e7-4890 v2, 2.8ghz, 37.5MB cache. the first is a 6 core cpu, the 2nd is a 15 core cpu. i'm trying to quantify the speed increase, such that if i have a piece of software that does NOT run threaded over multiple cores, how much faster is the newer cpu versus the old. other thing is, the operating system is linux. novell sles 11 or opensuse. thanks.
