I thought numatop should work on Haswell chip. However, it failed to launch. More info below.
$ sudo yum info numatop
Loaded plugins: versionlock
Installed Packages
Name : numatop
Arch : x86_64
Version : 1.0.1
Release : 5.fc20
$ numatop
CPU is not supported!
$ cpuid
CPU 0:
vendor_id = "GenuineIntel"
version information (1/eax):
processor type = primary processor (0)
family = Intel Pentium Pro/II/III/Celeron/Core/Core 2/Atom, AMD Athlon/Duron, Cyrix M2, VIA C3 (6)

extended family = 0x0 (0)
extended model = 0x3 (3)
(simple synth) = Intel Core i7-5000 Extreme Edition (Haswell R2) / Xeon E5-x600 v3 (Haswell-EP C1/M1/R2), 22nm
miscellaneous (1/ebx):

Could you try with latest kernel?
4.12 4.13 should be all ok.
Thanks

Cpu detection has something to do with kernel version as well? I looked at the code, it does not seem to check that.
