Tried 4.8.0-1 with similar results. Perhaps slightly better, but not much.

$ uname -a
Linux desktop 4.8.0-1-amd64 #1 SMP Debian 4.8.5-1 (2016-10-28) x86_64
GNU/Linux

Like 4.7, can't see what's hogging the CPUs as per-process CPU stats don't
appear to be correctly reported in /proc/<pid>/stat.

4.6.x continues to be perfect with respect to both overall performance and
the correctness of /proc/<pid>/stat.
