Geekbench's single threaded benchmark continues to show the superiority of Intel's single thread performance, including a 27% advantage of the Ryzen 7 2700X, and a 5% lead over the previous generation i7-8700K.
While the i9-9900K easily beats the other mainstream processors in the multi-thread test, the more interesting comparison is against the HEDT processors, with the i9-9900K only 10% behind the Ryzen Threadripper 2950X with double the core count.
This fluid dynamics simulation is very CPU and memory intensive. From the benchmark source website:
"The benchmark test case is the AGARD 445.6 aeroelastic test wing. The wing uses a NACA 65A004 airfoil section and has a panel aspect ratio of 1.65, a taper ratio of 0.66, and a 45-degree quarter-chord sweep angle. This AGARD wing was tested at the NASA Langley Research Center in the 16-foot Transonic Dynamics Tunnel and is a standard aeroelastic test case used for validation of unsteady, compressible CFD codes. Figure 1 shows the CFD predicted Mach contours for a freestream Mach number of 0.960.
The benchmark CFD grid contains 1.23 million tetrahedral elements and 223 thousand nodes. The benchmark executable advances the Mach 0.50 AGARD flow solution. Our benchmark score is reported as a CFD cycle frequency in Hertz."
Euler3D performance is impressive for the i9-9900K, trading blows with the 16-core Threadripper 2950X, and only losing outright to the 10-core Intel i9-7900X.
In both 7-zip compression and decompression, the i9-9900K only falls to the i9-7900X, managing to best even the 16-core Threadripper CPU.
