Okay so just to be completely upfront here. The integrated GPU on the i9-9900K isn’t any different than on the 8086K, 8700K, or even the 7700K. They all have the Intel HD Graphics 630. It wasn’t amazing with the 7700k and that isn’t going to change with this launch. Not to mention that I don’t think anyone should be buying a high-end CPU only to use dedicated graphics, unless it is a workstation situation where you don’t need any gaming or GPU compute performance. That said I did still test the 9900K in our onboard GPU test suite, just to be thorough.
My first test was the Cinebench R15 OpenGL benchmark. Here the 9900K came within a few FPS of all three of the 630 based CPUs and with the Intel 5775C and both of the Raven Ridge CPU ahead.
In both 3DMark tests, the two Raven Ridge CPUs are WAY ahead but you can see that the 9900K is slowly catching up to the 5775C, most likely because of overall CPU power.
In Unigine Superposition the 630 based Intel CPUs are all grouped up and then again the 2400G is at nearly double that score.
The rest of my testing was taking a look at actual in game performance. This was across a range of games from the past as well as a few new games mixed in as well. What I found was onboard performance was good enough to play older games like F1 2013 and tomb raider with the FPS being in the 30 FPS range. Not smooth but playable. This should translate to games like LoL, CS:GO, and DOTA 2 that are all flexible to handle lower power computers being playable as well. Newer games like Wildlands, Far Cry 5, and Shadow of the Tomb Raider, on the other hand, were all unplayable at 1080p, even at their lowest detail settings.
