Still a big difference tho: Get a used 7800X3D if you want to be close to the 9800X3D, IF YOU PLAY AT 1080p.

I get that this is about DDR4, as DDR5 RAM prices are high rn, but, check this out: They want to see the theoretical maximum CPU-bottleneck, but nobody has a 9800X3D and is playing at only 1080p?, Hardware Unboxed should have at least added 1440p tests, then the CPUs would be much closer together and the justification to use DDR4 would be even greater. They were blinded by their "we want to know the theoretical CPU-bottleneck". Well, Hardware Unboxed, then test in 720p, if you want to be scientific about it.

I do, however, like them exposing that for modern AAA games, 8 GB VRAM are not enough:
