Are we really going to play this game? From the guru3d review 10900k wins in CBR15, cbr20, blender bmw
Anyways, you said that the 5800x consumes half the power while it performs similar, which is NOT true. Gnexus had a pretty good blender test, the 10900k @ 125w performs on par with the 5800x. So you are off by a margin of 100%. Not a biggie, rounding error
When the 10900k does consume double (clocked to 5.2ghz), it destroys the electrons of the 5800x. Again, as shown by the gnexus review. So yeah, please, chill a bit with the amd glasses.
