AMD States That a Dual 3D V-Cache Design for the Ryzen 9000X3D Series Simply Doesn’t Offer Enough Performance Gains to Justify Costs

[Peter_Brosdahl]

AMD states that there are no technical reasons why it didn't launch a dual CCD processor with dual 3D V-cache, it came down to performance and pricing.

I'm guessing they prototype tested it, and it didn't provide enough uplift to justify the cost. I'd imagine the latency between CCD's and how the Windows scheduler works just didn't work out.

That's a better answer than just saying "Oh people wanted that?" At least they tested and said it wasn't worth the squeeze. 1k chip for on par performance would have pissed people off.

It may not have had benefits for games, but I sure could have found uses for it in distributed computing.

Oh yea totally but they would also want more PCIE lanes, and a ton more ram. I'm not building a hypervisor today limited to 256 gig of ram.

BUT yea that is still a fair point. Though for a home lab a 16 core box with 256 gig would have been fine.
