Performance - dGPU - Games: 3DMark Time Spy
Performance - Games - GeForce RTX 2080 Ti - 3DMark Time Spy
3DMark includes everything you need to benchmark your hardware. Time Spy is way more GPU dependant though. But still a very representative title in relation to PC gaming performance. Where in games the 9900K still is the leading processor, in a synthetic benchmark like 3Dmark, the tide has turned.
