@inf64 Actually it shows 4% according to the Computerbase.de data.
The 10900K is underperforming. The 9900KS and the 9900K are both at 5GHz. The 9900KS does slightly better.
Also the 10900K gets 1.528 Geomean, while 9900K gets 1.542. If you divide by clocks, Zen 2's advantage is 7.13% against the 9900K, but 8.1% against 10900K. Why? Because Spec doesn't scale linearly with clocks like any real world application.
If you only look at SpecInt, then the advantage over the 9900K is only 4.88%. SpecInt is more representative of consumer workloads.
And that's just SpecInt_2017. In SpecInt_2006, the 9900K is actually 1.87% faster per clock than Zen 2.
