The past few days a number of entries have been spotted for intel's pending 10 core Core i9-10900K. The numbers are very interesting to see back and forth.

The Core i9-10900K is to be the consumer flagship, hopefully, listed under 500 bucks. It has ten-cores at 3.7 / 5.1 GHz turbo, the Ryzen 9 3900 X with 12 cores and 3.8 / 4.5 GHz is also compared in the leaked benches. 

• In Time Spy Extreme, which only measures the CPU. A Ryzen 9 3900X (12C / 24T; 3.8 GHz / 4.6 GHz; 4 x 8 GiB DDR4-2400) scores  6,570 points.
• The Core i9-10900K (10C / 20T; 3.7 GHz / 5.1 GHz; 4 x 16 GiB DDR4-2666) achieves 6,124 points.

So that's lower than the Ryzen 9 3900X, however in regular time spy only 10 cores/threads are taken into the measurement, and then something interesting happens. The results are based on screenshots from Rogame and Tum_Apisak as linked above.

I've added the CPU score (stock clocked) towards our own CPU test results so these charts remain unofficial and speculative. As you can see the Core i9-10900K shines really well, the 10-thread load is in fact very representable for a good gaming processor. Since it is the other way around with Time Spy extreme, this indicates that intel can run several cores faster in that 5 GHz range as opposed to all cores, where performance drops. It is hard to judge and compare from leaked numbers though, keep that in mind:
