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).

There was a brief and glorious time before September 2025 where DDR5 was actually pretty comparable.

Even really good DDR5 could be had for cheap; I remember paying like 300$ for 96GB of high-quality M-die hynix DDR5.


July 11 last year I got a Crucial 128GB kit for $299. Those were the days…

DDR5 has always been twice as expensive as DDR4. But yeah when they were a lot cheaper maybe it didn't matter as much as it does now.

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.
