AMD ‘had to re-engineer’ the Ryzen 7 5800X3D for a re-release — 10th Anniversary Edition chip had ‘a whole body of engineering work’ put into it (www.tomshardware.com)

AMD’s David McAfee, VP and general manager of Radeon and Ryzen, says that “a whole body of engineering work” went into the re-release, as the original bonding process TSMC used for the Ryzen 7 5800X3D was no longer available.

[...]

“It completely changed the characteristics of how those two pieces of silicon are bonded together and how they were stacked together, and so when that first-gen facility really kind of went offline, then it meant there was a whole, you know, body of engineering work that had to be done to understand if we could even migrate the 5800X3D to the new, second-generation stacking process,” McAfee said.

Well, a facility that can handle that process going offline explains why the processor stopped being produced even though it's been in high demand for a while.

Why are they re releasing a 10 year old chip?

Is not really answered, just that supply is low and people still buy it?

The specific chip is only 4 years or so old. The 10 years refers to the Ryzen series first release.

Why this specific chip? It is the fastest available for the older AM4 socket + DDR4 combination, so it is highly sought after by people upgrading their older rig without having to buy new expensive DDR5 RAM or a new mainboard.

Quick recap of what's been happening recently:

  • The Ryzen 7 5800X3D is one of the best performing chips for gaming on AM4 motherboards that also supports DDR4. Demand has been high for this CPU even after it ran out of stock and even used units are sold far above MSRP.
  • Micron announced that they would stop providing RAM to consumers due to increasing demand for datacenters.
  • RAM prices skyrocket (especially DDR5)
  • Consumers turn to older DDR4 RAM since prices haven't gone up as much as DDR5
  • Demand for older Ryzen AM4 chips increases even more.

Consumers turn to older DDR4 RAM since prices haven’t gone up as much as DDR5

In absolute dollars, sure, but hoo boy those percentage jumps are ROUGH! I bought 16GB of no-name DDR4 for my aging desktop 15 months ago for USD 22. That same listing is now USD 100, and still pretty close to the cheapest retail I see, though that's only with an admittedly superficial search of Amazon and PC Part Picker.
