Not even that!

This is totally wrong the passmark score for the 6400 should be higher
Keira (01:56 PM, May 16, 2016)
CompuBench 1.5 (Face detection) why so different?! It looks like error in benchmarking process.
Cattman (11:25 AM, April 19, 2016)
the passmark score is worng. I Just tested my i5-6400 and it scores at 6742 points. please fix this.
Oltean (05:21 PM, January 5, 2016)
I think that PassMark score has an error...

Thanks, good to know! Also glad I'm not the only geek looking at this.
maximus buckley (02:16 AM, December 29, 2015)
the passmark scores are totaly wrong

Are you sure that's the PassMark score for 6400 single core?
