Performance - Games - Integrated GPU - 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.
If your Comet Lake series processor has an active IGP (Integrated Graphics Processor), it is based on Intel UHD Graphics 630. UHD Graphics 630 is an integrated graphics processor introduced by Intel in 2017 for the performance desktop Coffee Lake microprocessors. The 630 are the mid-range (GT2) IGP offered by Intel with 24 execution units. UHD Graphics 630 are found in 8th, 9th and now 10th generation desktop Core i3, Core i5 and Core i7 processors. The UHD Graphics 630 is simply a rebranding and is otherwise identical to the HD Graphics 630 found in desktop Kaby Lake processors.
