Weird they didn't talk about the DDR4->DDR5 transition. The 5800X3d->7800X3D went from DDR4->DDR5.
DDR5 is literally twice the price per GB. It's better for sure, higher bandwidth but waaaay more expensive. The 9800X3D supports much faster and even more expensive DDR5 than the 7800X3D too (DDR5-2667 to DDR5-5600).

  Ram is getting better, faster etc. except for the latency. I guess we still cannot bend the rules of physics.

    Latency has roughly remained the same since DDR2, no? So that has just about nothing to do with the improved performance of every generation.

    Latency had to improve because of the increased CPU speeds, but it didn't, causing a regression that's easy to perceive.
