The benefits of reusable design seem clear.

The only question I have is why can't they do a different IOD to put Zen4/5 on AM4 with DDR4 to combat the RAM shortages?

Isn't that one of the benefits of splitting CCD and IOD, or am I missing somethng and the memory standard is baked into the CPU µArch regardless?

RAM shortage will not last. You'd be an idiot to make a product that no one wants to buy in a year or so.

tbh I think they were the idiots for not making a separate IOD in the first place.

Why keep releasing new Zen3/AM4 products even before the RAM crisis?

Because even before that DDR5 was not exactly super cheap, they could have folded Zen3 and simply kept AM4 going with Zen4/5.

How many times do I have to repeat this?
They do not care about client.

They had, like, an actual mobile roadmap once.
Killed with zero remorse.
 
It is still ~98mm2 and not 70-80mm2 like older CCDs. Not that it is super huge or bigger than a smartphone SoC, but it is bigger than its CCD predecessors. The biggest of all time for consumers since Zen 2 switched to chiplets.

One huge benefit is, that it will be 16x the same structure (=1 core + cache), where salvaging is much easier than on a smartphone SoC.

If you're poor they have a peanut 8c CCD.
That's the point.
16c one is mostly for populating SP8 with goodstuffs.
 
"Xbox’s Asha Sharma Warns Memory Crisis Will Drive Up Project Helix Pricing and Availability"

"All of these things are an equation. Memory costs will impact pricing, will impact availability. As we think about being where the world plays, we will take that into consideration. So we're not ready to share a launch timeline right now. The world's pretty dynamic."

In other (old) news new Xbox is not custom chip, so it's basically vanilla RDNA5 as far as GPU is concerned.

officially as per Lisa Su, CEO, AMD, magnus/helix comes under semi-custom category

  1. soc as a whole is considered semi-custom
    1. unified memory
    2. direct storage & dedicated compression hardware
    3. poweful NPU
  2. GPU is standard replacement for 9070xt, but
    1. AMD has customized GPU as per DX 13 specs
  3. games built as xbox play anywhere share same code base with PC xbox app & Xbox helix console but
    1. at compile time, separate dx13 hooks/optimizations for console are created (unified memory & dx storage)
    2. separate deployment packages for xbox pc vs xbox console
    3. testing to be done separately for xbox pc & xbox console packages
  4. further changes for handheld / medusa premium optimizations
  5. further changes for xcloud deployment. but here Microsoft helps with some free server side support such as playfab etc.
  6. series x back compat may need further customization but I could be wrong too here

SoC itself - yes, but not the GPU part, at least according to Xbox, it will be same as RDNA5.

Perhaps it will be more custom for Sony OR their stuff will also be part of RDNA5, which seems likely to me.

as I said earlier RDNA 5 as a whole is customized for DX13 specs by AMD.

so Sony's customizations are about mostly removing (unnecessary) DX13 from RDNA 5

Customisation like that is easily a few hundred million $$$, for area purposes easier and cheaper just to scale down CU count, and try to pump frequency.

If Sony pays this money it's to add something really important, which from their joint venture likely to be just incorporated into RDNA5.
