Come on! Give us 5950X3D already
Now If they to were to make a 5900X3D or 5950X3D I will totally upgrade to those. Right now I have a 5700X and this CPU is awesome. At this time a X3D in a 5600 to 5800 would not be an ideal upgrade for me. I am still curious on the performance the new 5700X3D and hopefully it's a solid CPU.
Don't get me wrong, I'd adore a 12 or 16 core X3D Zen3 on AM4 chip, too.
However, 5600X3D-5800X3D all use one CCD. The Dual-CCD 5900X3D and 5950X3D absolutely did exist, by AMD's own admissions, presentations, etc. Merely, they were never serially-produced into a retail/OEM SKU.
Well they have to have left over 5950X chips that don't meet spec. So lets make them into 5900X3D or make them into like say a 595*X3D "16 core" variant to top off the AM4 socket series and get rid of all remaining stock. One hopes.
But for $550 no thanks Say $380 to $450 range.
Sadly, the TSVs and the vCache stack are bonded in manufacture; even if that were possible, it would not be commercially viable.
Had AMD produced Dual-CCDX3Ds for purchase, there'd be some
complications.
For instance, the 5800X3D already factory-recommends liquid cooling. Without dieshrinks, I'd imagine 12-16 core X3D chips would've required impractical levels of efficiency binning and/or would be at a high-risk for 'cooking itself' (from thermal density and vCache's
sensitivities)
To be completely honest, I think the 5900X3D and 5950X3D would've cannabilized AM5 sales (while being amongst the least-profitable-per-unit SKUs)
The 5600X3D and 5700X3D can be 'made from' single-CCD ZenX3D assemblies; a dual-CCD variant would require expanding production for a (slowly) sunsetting platform.
As far as I can tell, the base-silicon configurations we've seen on AM4, are
all we're gonna get. No backportings, no new dieshrinks, etc.
I can 'accept' no (consumer avail) dual-CCD AM4 X3D.
