Can I run multiple cores at different clock speeds?

http://unix.stackexchange.com – I see the cores on an Intel i5 machine I'm looking at can only be run at the same clockspeed: /sys/devices/system/cpu/cpu1/cpufreq/related_cpus lists all of the CPUs. Setting cpu1's clockspeed changes cpu0's, as expected. Supposedly the AMD A6-4400M machine I'm running should be able to run each core at a different clockspeed:/sys/devices/system/cpu/cpu1/cpufreq/related_cpu only lists cpu1. When I set cpu1's clockspeed by using the performance governor and echoing 1400000 to scaling_max_freq, cpu0's clockspeed remains at 2700000 as expected. Cpu1's scaling_cur_freq reads 1400000 as expected. (HowTos)
