Using the same graphics card, we tested the 3Dmark suite at the default.
Sky Diver is a DX11 test running at 1080P. 3DMark Time Spy is a DX12 benchmark test for Gaming PCs. It renders at 2560 x 1440.
At default speed, the Intel Core i7-8770K outperformed the AMD Ryzen 7 1800X by a fair bit. The difference is widen with the Core i7-8770K running overclocked at 5 GHz.
Time Spy shows that the result of both platforms perform equally well.
Fire Strike is a test on high performance gaming PCs. It renders at 4K UHD 3840 X 2160. It is the most demanding tests among the three.
We see another close call between the two platforms. The Intel Core i7-8770K has more potential for overclocking from 3.7 GHz base clk to 5.0 GHz gave it a better boost in performance than the AMD Ryzen 1800X.
