Core i9-9900K
Performance
Description
The Core i9-9900K is a cpu manufactured by Intel that was released on October 2018. This model has 8 Coffee Lake-S cores with HyperThreading, runs at 3600 MHz as base frequency and has a a thermal design power of 95 W.
Coffee Lake is the second refinement of Intel’s 14nm (Tri-Gate) technology. While it uses LGA1151 socket, it is incompatible with previous generations due to electrical changes in socket’s pins so these CPUs require Z370 chipset. This kind of generation introduced more cores in every range to compete with new AMD’s architecture. Coffee Lake uses DDR4 memory at 2400MHz for i3 and at 2666MHz for i5, i7 CPUs plus iGPU frequency has been increased 50MHz with respect to previous generation.

Non-optimized benchmark
The benchmark in Mode 0 (FPU) measures cpu performance with non-optimized software. It uses the basic µinstructions from the i386 architecture with the i387 floating point unit. This mode is compatible with all CPUs so it's practical to compare very different CPUs

Monothread performance graph
Monothread performance graphics gives the performance vs time. They are useful to measure the time it takes to the CPU to reach the maximum performance.
Usually, CPU's performance will be steady during these tests but if it has a slow frequency strategy, the first samples will show a lower score.

Multithread performance graph
Multithread graphs measure the performance against a heavy load during certain time.
If CPU's TDP doesn't limit the frequency and the machine is properly cooled, performance should remain steady vs time. Otherwise, the performance score will oscillate or decrease over time.
