I have Ubuntu 19.04(this problem occurs in 18.04 and 12.04 too), AMD-4600M processor.

A lscpu command, settings and /proc/cpuinfo say that my processor has 2 cores, 2 threads, 2048M l2 cache. But I find out that it must have 4 core 4 threads and 4096K.(Official site AMD)

How is it possible?

Am I fool?

Is the driver's problem?

Or something else?
